Hello friends. I'm from Poland and few days ago I've sold my Evo 9 because, I've built this:

My problem is very agressive throttle work. I mean - when I put gas very gently, car just kicks to front very hard and the same, when I ease down.

Second problem is very irregular idle. My cams are Kelford's 272'.
What should I do ? Mechanical I think everything is ok, so this problem prep ECU. I have Ecuflash, but I am....yyaa amateur in this :/

Please help

HAve you tried adjusting the throttle cable? That might help for that problem, not to familiar with the Colt and what tunning device you are using. I do know that for DSMs you can make the iddle not as bad by tuning the car with DSMLink or something similar. Hope that helps.

ECU is from Evo 9, just like all electric harness. What is procedure of adjusting the throttle ?

And one more thing: My car do not have EGR system, engine is from Evo IX MR. Maybe I should disable EGR function, but how ?

Maybe should change other values? Like RPM, ignition or... ?
