Definitive EFI ECU Pinout (KS Mod-friendly)

[foxdie]

Hi all!

The following is the current known pinout for the EFI (engine) ECU. It encompasses research from other dedicated members and myself through service manuals and wiring diagrams. A big thank you to all who contributed (and who contribute in future) :thumbsup:

Because different people reference each pin in different ways, this diagram refers to pins in both the wiring diagram format (absolute pins ie. 52) and by connector (C2).

In addition to that, I've also added the following;

1. A basic description of each pin to help diagnosis of faults
2. Where possible, additional uses for some pins, these are described at the bottom of the diagram

Very nice... so, reading the document I'm seeing your third note... is it possible to get the standard ECU to read from a MAP sensor on pin 75, instead of the MAF?

[foxdie]

Very nice... so, reading the document I'm seeing your third note... is it possible to get the standard ECU to read from a MAP sensor on pin 75, instead of the MAF?

Yes, but only for the purpose of logging (with EvoScan or the OpenPort 2.0s Standalone Logging-to-SD function). The ECU doesn't (yet) have the code to make use of a MAP sensors input, also this pin is limited to reading signals between 0-5 volts, applying voltage outside of this range WILL result in damage.

Things Pin 75 can be used for logging the following;
Wideband O2 sensor signal
MAP / Boost sensors that outputs between 0-5V
Any pressure / temperature sensors that output between 0-5V

Hope this helps.

[Nutter_John]

Yep 0-5v is the swing for the sensors on the car so do not apply 12v to it as you WILL feck your ecu

[foxdie]

Updated, thanks John :thumbsup:

[Reconstructor]

I heard, that VR4-s after 2000 have a different ECU. Is this correct? :)

[foxdie]

I heard, that VR4-s after 2000 have a different ECU. Is this correct? :)

Partially correct, although they were technically the same ECU (as all are interchangeable without any major problems), there were minor revisions; 7201, 7202 and 7203.

All pre-facelifts (1996-1998) came with a 7201 ECU, facelifts (1998-2003) received either a 7202 or 7203 ECU, the latter being fitted towards the later end of the manufacturing period.

All ECUs had near identical programming, the only differences were as follows;
Only the 7202 and 7203 can be reflashed with a cable. Reflashing the 7201 requires desoldering the EEPROM.
There are very minor differences between automatic and manual gearbox ROMs (such as "do not start if in gear").
7201 ECUs on Automatic cars were tuned for 260 PS (256 HP). 7201 ECUs on Manuals, and all 7202 / 7203s, were tuned to 280 PS (276 HP).

Hope this helps!

[Reconstructor]

Thank You very much for this detailed explanation. :) As I understand it, there is no any changes in pinout layout in different versions?

Nope, no pinout change between 8G VR-4 ECUs, although there are a couple of pins that only get used in some cases (auto vs manual for example).

[Reconstructor]

Understand, thanks again. :)

[Kenneth]

Some pre-facelift VR-4s (Notably Super VR-4s) came with MH7202 based ECUs.

[GalantOnly]

On FL ECU's pins 31, 32 and 46 are not connected...

[foxdie]

Thanks guys, doing an update now.

[GalantOnly]

...and pin 79 is brown/green on FL :)

[foxdie]

...and pin 79 is brown/green on FL :)

Brown / Green for Diagnostic Pin 26? You absolutely sure? Browns not used anywhere else on the engine loom (to my knowledge).

[GalantOnly]

Absolutely /yes
Sitting here with FL A/T loom on my table and wiring diagrams beside :)
It's Brown/Green from the ECU untill connector C-83 (under the radio) and then from C-83 till diagnostic connector it become Green/Yellow.
PFL loom have green/yellow all the way...

[GalantOnly]

And I can see that pins 53 and 59 are very complicated fellas:rolleyes4

Pin 53:
PFL - white and goes straight to ASC ECU pin 19
FL - black and goes straight to A/T ECU pin 54
Cars with TCL, but no ASC, it goes to TCL ECU

Pin 59:
PFL - black and goes to ASC ECU pin 6 (and grounded)
FL - white and goes to A/T ECU pin 53
Cars with TCL, but no ASC, it goes to TCL ECU

[foxdie]

Cool, updated first post :thumbsup:

Edit: missing info in post 17

Jeez, um.. okay.

1. I was under the impression that all facelift autos did NOT have ASC or TCL, is this correct?
2. What about manuals?

[GalantOnly]

...and pin 60 ain't connected at all :) And it's both on PFL and FL...

[foxdie]

...and pin 60 ain't connected at all :) And it's both on PFL and FL...

??!? What are you talking about? Of course it's connected, it's how the ECU measures your speed, people cut this wire to get around the speed limiter.. :)

[GalantOnly]

Jeez, um.. okay.

1. I was under the impression that all facelift autos did NOT have ASC or TCL, is this correct?
2. What about manuals?

1. Correct. That's why those wires goes to A/T ECU instead of ASC ECU
2. On manuals the pins 53 and 59 are empty :)

[GalantOnly]

That's pin 86...:)

[foxdie]

That's pin 86...:)

Great, that's 2 problems I've got to deal with now :) *gets his soldering iron*

[GalantOnly]

Here's the pics of the low row of connector "C", which is called C-37 in diagrams. You can see pins from 57 (blue/white) to 62 (red/white). As you can see, pin 60 and 61 are empty on A/T's...:) Also pin 59 is empty om M/T

Connectors from left to right: PFL M/T, PFL A/T and FL A/T

[foxdie]

Thanks for that Alex, that's great :)

Question, does pin 59 serve any function other than ground, particularly on FL auto?

And anymore to add? :)

Not sure about any other functions, but you can see how pin 59 looks like on the diagrams...:)

[foxdie]

Okay, before I upload the next version, can anyone confirm if Pin 60 (Vehicle Speed Sensor Signal) is present on a Facelift Manual?

It was on Kats pinout as a white wire with green stripe, yet we've got proof above that it's not present on all prefacelifts and facelift autos.

[foxdie]

Version 5 uploaded with expanded definitions of some pins and all information above (up to this post), as FL M/T pin 60 presence is unconfirmed I've put a question mark beside it :)

[taylor]

D-1 is Start signal from ign barrell on manual

[BCX]

D-1 is Start signal from ign barrell on manual

This is correct. this should be start.

Also, shouldnt C-10 and C-11 be front and rear O2 heaters?

if i cbf getting to my ECU, i'll double check...

Edit: this is based on disassembly.

[GalantOnly]

D-76 is for the front O2 heater and D-75 is for the rear (on N/A V6 only)

[foxdie]

Ahh! This would explain why I'm having problems as described in this post (http://www.clubvr4.com/forum/showthread.php?60947-Switched-maps-testers-wanted&p=676453&viewfull=1#post676453).

I need to consult with Ken why he labelled this pin as being usable. For now, I've removed it from the list of +12V pins and amended the description for the diagram for pin D-1.

Before I release a new version, please can I double check pins A-12 and A-25 are both only connected to +VE when the ignition barrel is set to "On" and not "Start"?

I'm going to relabel them as clearly as I can.

[BCX]

Before I release a new version, please can I double check pins A-12 and A-25 are both only connected to +VE when the ignition barrel is set to "On" and not "Start"?

they look like the power source for coils, injectors or something. Usually after main engine control relay, colour turns to red as well. black/white usually is ign1 from barrel.

i'm only going from all the mitsu looms i've dissected over the years. Is there any decent wiring diagram for our car?


D-76 is for the front O2 heater and D-75 is for the rear (on N/A V6 only)

Those pins sound like the o2 signal. our oxy sensors are 4 wires, so they have an internal heater that the ecu usually controls. (unless they are perminately connected to 12v)

i couldnt get to my ecu tonight, so i'll try and have a look tomorrow.

[lathiat]

Merlin's legnum tuning guide refers to using pin 7 on connector 4 to connect your MAP sensor. presumably a 0-5v input.

but his document never expands on what address you can log it from and such.


anyone know about that?

[foxdie]

Is there a link to said document? I'll try and trace that pin back tonight and see where it goes.

Curiously in section 10 he talks about using the 1 rear o2 input as EITHER map or wideband.. but in his ecu pinout he marks the map sensor for a different pin.

so not sure where he's got it from.

[foxdie]

Yep, I suspected as much after digging around Evo 7202 / 7203 pinouts, he's referencing pin 77 which is unused as Hamish@EvoScan told me, sometimes you just gotta try wiring something to it and scouring the MUT requests :)

I also suspect pins 73 and 74 can be used, and that all "D" (C-39 in wiring diagrams) are all 0-12V tolerant inputs. I'm not willing to bet an ECU on that though, someone fancy donating a 7201 to science? ;)

[foxdie]

Right, I've traced all the unused pins on a VR-4 7202 PCB (JE331B154C).

Pins 9, 20, 24, 34, 51, 61, 73, 74 and 77 all abruptly end where there's a missing component (ie. different board revisions).

Pin 42 however appears to go someplace, first through a resistor and then into a whopping capacitor, then to an unpopulated IC connector, this says to me it's some kind of output that can possibly be made to work as an output if we can identify the IC (IC104), however this doesn't seem to be used on Evos 4-6 either so may be a lost cause. Pins 39 and 40 also go straight to this IC104.

Pin 33 interestingly goes all the way back to close to an IC right next to the main CPU, passing through a darlington pair (http://en.wikipedia.org/wiki/Darlington_transistor), on Evo 4-5 this is used to turn the alternator on and off (G terminal), so this may be a viable ECU output for something like an Intercooler Spray :thumbsup:

Pin 6 also goes to transistors near the ECU connector, this is used as the Secondary Air Solenoid (http://www.zorce.com/zforums/viewtopic.php?p=43946) on Evos 1-6 to keep turbos spooled up during gear changes and as the Exhaust Gas Recirculation control on Evos 7's for emissions. This could also potentially be used as an output :)

How Merlin used pin 77 for a MAP sensor then I have no idea, I'm wondering if the information he posted was untested and using info from Evo ECUs which have MAP sensor circuitry. What we might find is we can add these components manually, I'll do some more digging when I get time.

[foxdie]

That said, I've just compared the above board to an Evo 5 7202 ECU JE331B153C (http://i245.photobucket.com/albums/gg67/2rortu/EcuFlash/Dead%205%20ECU/dead5ecu2.jpg), the PCB layout is notably different. Could be the above are just remnants of development removed or reserved for later use.

Still, it might be worth someone looking into repopulating certain components to see if extra inputs / outputs can be manually added.

Also doubly worth investigating pins 6 and 33 as outputs as those look like they could be ready to rock :)

[lathiat]

Thanks heaps for your research foxdie it's highly appreciated.

I wonder what the pin 53 A/T ECU input is. Is that the torque reduction request switch line or something fancier?

[lathiat]

Also did you trace pin 60?

Pin 60 is front o2 heater sensor on the evo 6.. might be of interest given the input is still there.


doesn't look like there's likely to be more 5V inputs connected, theres certainly nothing on the evo 6 for comparison.
only hope would be to trace the pinout of the MCU itself and look for the analogue inputs i think?

[foxdie]

There's more science to be done yet!

I started at the other end, the Hitachi H8/500 series CPU has 12 Analog inputs, each capable of reading 0-5V with 10-bit precision. I'm trying to match each one up to their respective ECU pin input to then determine if any are left over for use / abuse ;)

After that, we should have a good idea (for the hardware side) if we can add more inputs, software however will be left to those with the tools to edit roms such as IDA Pro, this shouldn't be too difficult. Here's the list of all the ADC inputs and their addresses;

51151

More info to come as it unravels :)

[foxdie]

Yep I've been doing that for the last couple of hours :)

Unsure about pin 53, could be the torque reduction signal, but then didn't that just ease up the torque converter not engine power? Someone will confirm.

Pin 60... Nope, I've been waiting for someone to confirm its function, I'll take a look at that too.

[lathiat]

So there is likely:

TPS, IAT, WATER TEMP, BAROMETER, VEHICLE SPEED, CAM PS, CRANK PS, MAF, KNOCK, LAMBDA1, LAMBDA2

I'm fairly sure those are all going to be analogue inputs - which is 11 total.. not sure what else there is or if any of those are not 5V analogue.


It would appear that basically all the analogue inputs are on that 1 connector, which would make sense I guess.

[foxdie]

Although logical, I don't think thats true. Until I see direct proof, I'm not convinced that all those inputs are analog, given there's a total of 86 possible input pins on that CPU (76 digital input / output lines + 12 analog input lines).

TPS, IAT, Water Temp, Knock, Front Lambda and Rear Lambda will most likely be analog.

Barometer and MAF I'm not sure about, I believe that's a frequency input.

Cam PS, Crank PS and Vehicle Speed are hall effect sensors and will most likely be digital.

I'll update when I know more :)

Ahh fair point the hall effects would likely be digital and at a guess possibly interrupt driven. I'll stop thinking about stuff while its 1AM and let you finish tracing the board. :-)

[Nick Mann]

The air flow from the MAF is definitely Hz, but I have no idea on the IAT and Barometer. I am pretty sure all those signals originate from the MAF though.

[foxdie]

Sorry Trent, Pin 60 is a dead end too, missing components :)

[foxdie]

Right, it's taking about 30 minutes per trace :rolleyes4

AN0 = Coolant Temp Sensor
AN1 = Intake Air Temp Sensor
AN2 = Barometric Sensor

I guess all bets are off :uhoh2:

[BCX]

Sorry to ruin your parade :p

Here's what i've got from my notes. I'll be releasing a bunch more info about pins to use, etc once i can get my notes together into something that I can present.

AN0 = Coolant
AN1 = IAT
AN2 = Barometer
AN3 = Front O2 / Second Front O2 (input is multiplexed)
AN4 = Rear O2 / Second rear O2 (input is multiplexed)
AN5 = Battery
AN6 = Knock Sensor
AN7 = TPS
AN8 = fuel tank pressure - Unused on VR4
AN9 = Fuel level - unused on VR4
AN10 = Fuel temp - Unused on VR4
AN11 = MAP sensor - Unused on VR4



Cam Angle, Crank Angle, MAF, Speed, IFS all feed into H8's timer (pins are set as inputs for timers) as they are digital - H8 looks for either the rise or fall of a signal, generated an interupt that the ecu actions immediately (ie load next value into timer for injector time, coil dwell, change other I/O pins) - then resume back to the normal program loop

Airflow, vehicle speed timers are slightly different - it measures the time between pulses to determine these values - no action takes place in interupt, just update memort location with new value.

TIMER1 = Injectors
TIMER2 = Coils

Have fair idea on the other timers, but just confirming a few things before i release info.

I'd rather get my fact right before releasing info then let people discuss and prove it wrong, than for people to assume its correct.

[BCX]

The air flow from the MAF is definitely Hz, but I have no idea on the IAT and Barometer. I am pretty sure all those signals originate from the MAF though.

air flow is digital, IAT and Baro are analog.

Also field response from alternator is digital i believe.

[foxdie]

Ruin my parade will you eh?? *takes off his Stilettos* You're off my xmas card list now!

Just kidding ;) I'm grateful you've saved me a lot of hassle, tracing lines with the naked eye has given me eyestrain.

Interesting about AN8-11, I'll focus my tracing on there to see if those can be repopulated :)

Have some rep :thumbsup:

[foxdie]

This is proving most difficult given the fact the traces for those pins go straight under the CPU. Anyone got any photos of a VR-4 7202 board with the CPU desoldered? /help

Your other problem is these ecu boards are multi layered. I think I counted 5 or so layers...

[Kenneth]

Run a continuity test between the pin and the point the track disappears.

[foxdie]

Run a continuity test between the pin and the point the track disappears.

Thats what I've been doing, although I'm wary the wrong combination could send the "wrong" voltages into the CPU and damage it.

[Davezj]

please bear in mind, when you do a continutity/resistance test you put 2V (ish) into the circuit, this is how the meter calculates the resistance. so as long as the circut can take 2V you will be OK.
and by all reconing the inputs and outputs are 5V and 12V, even if there are 3v3 in's or out's you should still be OK.

[foxdie]

Although your logic is sound, I only have a cheapo £10 multimeter from Maplin, it's got a 9V battery in there so I wouldn't put it past it to use 9V again for the continuity tester.

[wintertidenz]

Chuck an LED across it to see how bright it glows with the continuity test.

Mine is an Anco cheapish multimeter, and I would estimate the voltage to be about 2v as it's quite dim.

[veegeeta]

hay mate have this diagram and can see tps signal wire goes to ecu pin 84 or as some know it as pin 14 now my question is that there are 3 wires to the tps i need to find out where the other 2 go i know one is a earth and the other is a 5 volt power suply if im correct? i need to know exactly where these 3 wires go if pin 84 is signal then where on ecu does the other 2 go ??????? thnks for your time so sory didnt mean to afend not very good with computers

[foxdie]

Hi Shane,

This isn't the thread for that kinda discussion, also I don't know off the top of my head, it'll require some research.

These threads might help:
TPS measurement. (http://www.clubvr4.com/forum/showthread.php?61403-TPS-measurement.)
ASC to Manual Throttle Body questions (http://www.clubvr4.com/forum/showthread.php?55710-ASC-to-Manual-Throttle-Body-questions)

Ps. Asking that question in this thread, via PM and as a visitor message on my profile could be considered as harassment, please don't do that.

So is pin 86 the pin for speed signal from sensors or abs INTO the ECU or is it the speed signal OUT of the ECU for driving the dash? The reason I ask is I am prototyping an in car mpg display and I am looking for the speed signal probably to the instrument cluster to do the calculations on the fly to produce the correct figures. I hope to sell them after, they will replace the clock which will hopefully be displayed on the same display.

Kind Regards

[BCX]

speed input so ecu knows vehicle speed. signal is produced by pulse gen on gearbox.

Will pins B-11 and B-14 be suitable for 'alternative input' on automatic transmission PFL/FL's too? The pinout diagram shows this for MT only. Since they're listed as unused in AT I expect they will work too?

Hi Dice,

I'd look at your wiring loom and see, if there's no wires in those slots then I'd probably say yes. You'll still have to flash Kens KS Mods ROM to make use of them, which I believe is a MT ROM anyway, so they should work. You may have issues with your AT ECU and TCL if fitted, but I haven't actually heard of any problems to date and KS Mods has been run on AT already :)

On both my early PFL and late FL, the wire colour from OBD pin 1 to ECU pin 56 (pin 6 of third connector), is grey with a red trace. Not green with a red trace. I've checked at both ends of the wire, to be sure!

Also, pin 26 is black on the diagram, but the white writing says 'white' instead of 'black'! /lol

[BCX]

C3 is not digital output, it's a serial output. Baud is 15625. Outputs 4-5 parameters (rpm, load, accel enrich, etc) with a rudimentary checksum for TCL system to get this info from the ECU.
C9 is the RX pin on the same serial interface. Tied to ground as it's not used in VR4.

C6 - typo. This isn't L-line. Mitsubishi use K-line only, no L-line as per iso9141-2.

[BCX]

some more info I posted on OZVR4 attempting to reverse engineering the hardware of the ECU.

https://www.ozvr4.com/threads/ecu-pin-out-complete-for-vr4.6395/page-2

[Confused]

That's really interesting, thanks BCX!

Don't suppose you've decoded the signal from the Gearbox ECU into B16? :D

[BCX]

Nah I haven't as mines a manual.

Looking through the Magna workshop manual, there mention of "Engine-A/T ECU requesting torque reduction", the troubleshooting guide implies its a simple pull-to-ground digital input that the TCU controls.
Haven't looked at how the ECU actually reduces torque, but there is a table that appears to modify timing. Might be related? Might have to rabbit hole and get back to you.

[Confused]

My initial thought was that it swapped between the two HI/LO Fuel/Ignition tables - I could have sworn that they had slightly different values in them, but looking back now, they seem to be duplicates of each other. Any insight you can provide will be great!
