...or has one out and can take picture of it?
Just the outside of it?
96-97 Mitsubishi Legnum VR-4 Type-S
I was actually interested in this part of it:
-LegnumVR4- Thanks anyway.
The reason I asked was this link:
2G EPROM DSMLink ECU upgrade
Its an ECU upgrade for 2G DSM cars (95+ years) with an OBDII, with lots of usefull stuff... most of which could only be found on a good aftermarket ECU.
" To check for an EPROM inside your ECU, pull the ECU out and check the sticker on top. The sticker should have a part number on it (e.g., MD309947) with some other numbers and a letter in the lower right hand corner. If the letter in the lower right hand corner is an "E", then the ECU has an EPROM."

Took a photo of the sticker and a photo of the insides.
Thanks again -LegnumVR4-
Will try to find out if it is possible to get this thing working on our cars...
Not sure if it will work. I think its for the 4g63 engine. I'm pretty sure the US guys are working on the next type of ECU's which are the same as ours. Same as their 8G Galants and Eclipes.
Reply from DSMLink stuff:
Currently, no. But we're always open to ideas. In those pictures you
sent, can you get me the numbers off that processor? It's the biggest
surface mount chip on the board.

Well the biggest chip number is:
Main number with Mitzy symbol is:
MH7201FS
Other info under the main number:

For those of you who are lazy enough to check out their site ( www.DSMLink.com ), here is the "short" feature overview of DSMLink:
" DSMLink is the datalogger and tuning tool for the second generation (1995-1999) turbocharged Mitsubishi Eclipses and Eagle Talons. Rest assured, this is not just another OBD II datalogger. No, no. This is a full-fledged datalogger and tuning tool. DSMLink not only provides high-resolution datalogging facilities, but also provides the tuning tools necessary to actually do something with all that data you capture. DSMLink includes fuel and ignition timing adjustments in the factory ECU. You retain all the driveability of the factory-calibrated fuel and timing maps during cruise operation, but gain full control over things at wide open throttle. You simply specify RPM-based adjustments and DSMLink automatically creates the 3-dimensional mapping used internally by the ECU. It's a very easy, yet very powerful way to tune your car's performance at the track.
DSMLink development is focussed on one thing and one thing only. That is to provide the DSM community with the best engine managment system we can fit inside the factory ECU. We constantly ask users for their feedback on which features they want and we strive to provide the ones we can. We feel version 2 is a clear example of this dedication to the user community."
DTCs - Allows the user to disable some of the more annoying check engine light conditions.
Fuel Cut - Removes the airflow fuel cut.
Speed Limiter - Removes the speed limiter.
Knock MIL - Flashes the check engine light if timing is pulled back more than 5 degrees (user definable) due to knock.
Fan Control - Allows the user to turn on both radiator fans to their highest speeds.
Fuel Pump - Allows the user to force the fuel pump on without running the car. Useful for draining the tank without heating up the engine.
Cam Inverter - Manipulate the cam sensor signal so that injector firing order is swapped. Useful when DSMLink is installed in a car with a '97+ or 1G-style cam sensor. Yes, you still have to swap the plug wires...there's not much we can do about that one.
A/T Timing - Retains ignition timing in between shifts on automatics.
Injectors - Provides compensation for aftermarket injectors; idle like stock even with 720 injectors.
Fuel/Timing - Provides RPM-based fuel and timing adjustments. The ECU automatically calculates the more complicated airflow based adjustments from your settings.
RPM Limits - Allows adjustment to rev limit, launch RPM, and idle point.
Datalogging - Capture everything you could imagine, including knock retard! Sample rates of almost 300 bytes per second, which translates to roughly 20 frames of 11 values per second.
Log Notes - Enter notes with each log file to record things like quarter mile time and fuel and timing setup (optionally grabbed from the ECU for you).
Autoframe - Frames a data capture automatically for a drag strip pass. This trims the data before and after the pass so that you're left with a clean, concise view of what happened going down the track.
Octane Reset - Resets the long term octane value on every restart of the car.
BCS Flicker - Removes the boost control solenoid (BCS) flicker between 2300 and 3900 RPMs.
Export - Exports displayed data to a file appropriate for loading into Excel for further analysis.
MAF Comp - Allows the user to "dial in" changes made to the air metering system (hacked MAF, bypass tube, or GM MAFT type unit).
Speed Density - Allows one to switch over to basic speed density operation when the existing MAF system is about to over run. A functional MAF is still required and the user needs to provide a manifold pressure signal to the ECU.
MAF Clamp - Defines a switch off point for the MAF, above which the ECU will extrapolate airflow data rather than read it from the MAF.
Coolant Offset - Provides adjustments for aftermarket (lower temp) thermostats.
Coolant MIL - Warns the user when coolant temps exceed a certain value (defined by the user).
Nitrous Controls - Provides basic nitrous controls. Parameters include RPM window, throttle position, speed, and knock retard.
No-Lift-To-Shift - Keep the throttle down during shifts. Reduces lag and provides smoother shifting in many cases.
Antilag - Provides a drag-style antilag system for spooling those large turbos at the line and during shifts.
Higher Idle - Provides necessary adjustments to cleanly support higher idle values (over 1000 RPM).
TPS/Idle Switch - Provides simulation of an idle switch and adjustments to the throttle position value "seen" by the ECU to support aftermarket throttle bodies.
Knock Control - Allows the user to adjust the conditions under which the knock sensor is used by the ECU. This provides a work around to the common "phantom knock" problem.
Gauge Display - Allows the user to change what gets displayed on the factory "boost" gauge. Common selections include coolant temp, idle control, O2 sensors, etc.
ECU Config - Saves and loads the entire ECU configuration to a single file. Also includes this data inside each datalog so you always know how your ECU was configured at the time a datalog was made.
OBD II Fix - Fixes the OBDII MIL bug in the '95 ECU. Mitsubishi did a recall on the '96 ECUs but offered no fix for the '95.
Cranking Fuel Cut - If the throttle is wide open while cranking, injectors are shut off. This seems to help clear out flooded conditions produced while attempting to start in REALLY cold environments.
Faster Comm - Tweaks to the ECU communication layer provide for quicker responses to ECU configuration changes made via the laptop.
The Dataloging feature has a lot of displayable values... you can find a list of them in DSMLink V2 PDF User guide. Really impressive. Actually I found this link while I was searching for a good OBDII Dataloger for my car. Well, this thing looks promising...

My friends here with their 4G63 VR4/EVO's run software like this. All types of programing can be done to the chips. Very impressive what can be done.
Was the guy going to check on the chip info that I posted up Valmes?

Reply from Thomas Dorris of DSMLink:
"That processor does seem familiar, but without an ECU
here to verify, it's hard to say for sure. It's also very hard to know
if/when Mitsubishi might have changed anything in that ECU line up. For
example, in the 2G DSMs ('95-'99) there was a different ECU *every* year
with three different processors! The '98/'99 DSM ECUs used the MH7202F
processor, which we have just recently begun to play around with. It's
possible that your VR4 ECU is very similar to this one. If so, that
means it's reflashable (no EPROM).
So yeah, I'm interested, but it would be a hard market to enter with so
little information (we don't even get that car here in the states!). I
will definitely keep it in mind, though. If there's any chance you can
locate one of these ECUs for us, I'd be more than happy to take a closer
look. I'll re-imburse you for the expense, of course. It would also be
useful to get some pictures and/or processor numbers from other users
with different years of that car. It would be GREAT if Mitsubishi stuck
with one ECU design for 5 years in a row, but that's highly unlikely.
Do you know which year car that particular ECU you sent me pictures of
and the information below came from?
Thanks again,
Thomas Dorris"
Interesting stuff Valmes
That ECU of mine is a 1996 model from an auto so thats the 250/260bhp model.
Chassis number is: EC5W-0003617
Model number is: E-EC5W LYGF
If any of that helps.
I do have the 2001 ECU in my car at the moment which is 280bhp but haven't gotten around to looking at it yet. Maybe one of the other uses out there could crack one open? I'm thinking that the auto 280bhp model is the same as the manuals 280 ECU.
I've had no problems running the later models ECU in my car so everything could be based on the one model, manuals included.
Big Dave u have a face lift Legnum VR4 and a camera, nudge nudge, wink wink
So does anyone has a spare ECU? Or where to look for a used one?
I doubt I will be pulling the ECU anytime soon though
Can't part with the spare one at the moment. Maybe a ClubVR4 fund raiser to buy a ECU for research?
How much would a used VR-4 ECU cost?
I'll try and do some ringing around tomorrow to find out.
So how much boost is safe to run on a stock 97 VR4 ECU without the fuel supply dangerously leaning out?
