Hey guys,

i did an adapter harness for my evo3 and car runs fine beside of the boost control, my wastegate solenoid somehow doesnt works.

My ECU is an Evo7 one MR560648

Anyway i want a fresh working Rom adaptation for my evo3 and thought i may ask if there is someone willing to help me to get the values over from the rom i got from the early evo forum, i think its the one from evonut270 with Rom ID 96530006.

The difficulty i am facing here is that a few things may have changed and the scaling is in kPa instead of % or Fahrenheit instead of Celcius.

Regards

 

I did a similar project 4 years ago, the stock E7 rom should work fine, or use the Tephra 9055 v5.1. Use the injector scaling/latency found in the evonut rom. I had hard time attempting to scale maf, I ended up installing a MAF from a newer evo (4-9).

 

You cant run dsm maf on Evo 1 to 3 or on DSM swap when you run the 8 ECU


disable imobilizer too dont forget

 

???

2G DSM MAF and Evo 1-3 MAF are the same and can be used with the Evo 8 ECU. It's just a matter of transferring the right MAF configs. over to the 8 rom. Been running my Evo 1 on an 8 ECU with stock MAF for 5 years now.

 

Im Driving with my e7 ecu since 3 weeks now and i guess the rom i have is the v5 Tephra Mod...

Wreckleford, do you wanna help me to get the v7 file running and adapt the values over?

 

I run 96530706 V7 on evo3 years ago but with evo 8 ecu. pm me your email and I can send you that working rom with rescaled maf, 510 injectors, tuned fuel/ignition maps etc.
you may have to adapt your maf scaling, fuel/timing tables for your car though

 

totally wrong information

use the 90550001 rom

 

as far as i understand, the roms dont have a restriction regarding to the MAF you use, you only have to rescale it and thats it?

 

yes!
finally i have good base file which works fine, even the boost control/wastegate is working now altough not perfect but its okay for now =).

Big Thanks go to stunt2 for his great rom file with Launch Control (y)

But i still have a small problem with the boost control, when i hit boost my wastegate/boost is fluttering between 1.0 to 1.2 bar.

similar to this video from 5 to 7 seconds

I still have the stock setup wastegate solenoid which ive removed the restrictor inside, with the stock evo3 ecu i have a boost from 0.9 bar to 1bar peek but its stable and not fluttering.

Im running an Apexi Cone filter and have a BOV which looks like a Forge but i think its a cheap knockoff (was on car when bought)

Is my Problem anyhow regarded to the ECU Wastegate settings, anyone familiar with it here?

Or just get a 3Port/TriPort Pierburg Solenoid and come back here again?
