Kenneth's ECU Mods V2.0

[foxdie]

@Adam.Findlay I believe I spotted on the net once the Supra looms were near identical to ours, be aware there's 2 pin sizes, large ones near the edges of connectors for high current purposes, and lower current smaller pins in the middle. It's the smaller ones you need for the switch inputs.

[Adam.Findlay]

Yip i know that. the stock mk3 supra connectors were all the large type ones. maby you looked up mk4 supra ones.

[lathiat]

The connectors are the same as Magna in Australia, might be able to pick up some connectors/harness cheap.. I had to destroy my connector to get the pins out.. seemed impossible to get them out.

I'd be happy to finish cutting up my connectors and post people out a set of 4 for $10 PP.

Hey Adam,

Map Tracer is picky about the names used in the tables, I found that removing the # characters from the names of the two hi octane ignition and fuel tables would allow them to load correctly.

I would load up a copy of the xml def file I was using but it is modified significantly from what Kenneth originally published to attempt to tidy it up and remove unused scalings. Just tweak the table names and see how you get on.

Cheers

@pbaron could you please post your def files for evoscan Im having real trouble getting map tracer to show the extended maps want to tune for my cams ASAP

[pbaron]

Here is one of the cutdown versions I was using, I just checked and this loads kens 1.03 image in maptracer.

You should be able to tweak it for the 2.0 image or use it as a guide. The 2.0 image is not available to download so I could not confirm that this def will work with it.

Cheers

More documentation time!

Although Ken is working on a Windows app to help automate setting up his ROM, the following documentation should help people in the short term understand how certain complicated parts of this ROM tick. Hope it helps someone

Link is broken!

Fixed, seems the forum software decided to turn the PDF into an image, d'oh

Update:

Jason was right, the image I had up was FUBAR. It has been corrected now.

I have also added a little program (Requires .Net framework 4.0 or it won't work). The program isn't finished and I make no guarantees about it working. Use it if you like.

Some notes on the program

• You can change the configuration names on the matrix tab
• Some of the values have scalings (such as tps) which add stuff like a % sign. When editing the value, don't put a % sign or it wont work. And don't prefix hex with 0x.
• In theory you can change the names of the maps too, but I haven't finished that yet.

The idea is that it makes it easier to setup the maps as you can better see what you have done. I wrote the program for myself but thought someone else might find it useful.

[scott.mohekey]

The new app looks good Kenneth. I'm going to have to reread all of this heavily when it comes time to setup and tune my car with the extra turbo etc. But you've made it more than possible to go to ridiculous extremes like I'm planning with my car using the stock ecu, and for that I thank you! I'll definitely be flicking you some money when it comes time to get everything up and running.

[Adam.Findlay]

cheers Pbaron didnt end up needing it carl and i got it all sorted and switched maps are go! just need to spend some serious petrol money on tuning the maps..

[Kenneth]

feck. Another error found.

I am currently writing more code in the configuration program and since it actually does the same sort of thing as the ECU to do lookups, its finding typos

I'll amend the first post when it is fixed. In the mean time, don't use WGDC map 5

[foxdie]

In the mean time, don't use WGDC map 5

Although it'd be good to have fixed for completeness, I doubt this'll be a hassle to anyone Ken, it's not like they've not got another 7 WGDC maps to play with

Hello guys, i have made a setup with TD04 13G ( GTO turbos ) in my VR4 and now i'm trying to tune this one with the KS Mod V2 but i need the STARTING IPW ADDER vs TEMP because i use E85 and i have a very bad starting.
I don't find this map in the Ks Mod V2, she is available ???

It is this MAP

Thanks

Hey all !!

No ansewer on last post??

For all please , i would like to know if 'im right :

For the scaling:

<scaling name="IPW mcsec" units="mcSec" toexpr="x*432/1000" frexpr="x/432*1000" format="%.0f" min="0" max="255" inc="1" storagetype="uint8" endian="big"/>
<scaling name="StartupIPWTime" units="ms" toexpr="x*0.008" frexpr="x/0.008" format="%.1f" min="0" max="500" inc="1" storagetype="uint16" endian="big"/>

For the table:

<table name="Cranking Enrichment IPW Adder (Main)" category="Fuel" type="2D" level="2" scaling="TimeInjCranking">
<table name="Coolant Temperature" type="Y Axis" elements="8" scaling="Temp"/>
</table>

<table name="Cranking Enrichment IPW Adder " category="Fuel" type="2D" level="2" scaling="TimeInjCranking">
<table name="Coolant Temperature" type="Y Axis" elements="8" scaling="Temp"/>
</table>

If yes , it will be nice , because cold start with E85 is little hard!

Thank's all

i believe the table your after is already defined in my defs... just haven't applied a scaling to it.

If not, i can have a look for it.

Cheers mate, i'll amend my defs to apply the scaling... hope to have a new version published soon (will try and incorporate KSMods too)

Off topic: i have some stuff defined for 7201 roms.

Thank's a lot Sir . I add this code on your KSModsBase and i'll try this afternoon on the car ...

Big thank's

Let us know how it goes.

Please also post up your values for E85, It would be a great help for those of us considering going with E85.
