I’m going to try and get the best description of my car, so I bought this from a guy a few weeks ago and it definitely needed some work (too good to be true deal) 2010 Lancer Ralliart
I’ve been having the biggest issue down the highway mostly up hills above 60 mph it’ll cut off and go into limp mode. The car does need tuned, but the guy had put 1000cc injectors, fuel pump, evo Mr turbo and intercooler, evo Mr transmission, intake, exhaust and has a Chinese hks blow off. Only other thing I do have front o2 sensor out. This is my first time getting into modded car stuff. Opinions?? Thank you!

I ordered all the things to do the tuning myself, and flashed the transmission so it seems to be working properly now. The limp mode issue still persists.
I am stuck though, in that EvoScan is not logging data properly, and cannot read from ecu as it does not show my ecu. Along with this, using Ecuflash pulling from the ecu it doesn't bring anything back.
I found a stock EvoX tune map rom that I thought about uploading, but hesitant in that if i do, there doesn't seem to be a way back.

Any help is appreciated! if this needs to be posted elsewhere also let me know!

 

Hmmm, I'm the local yappy idiot so ignore most of what I say, but like no front O2 installed at all? Start there. Does condition persist when ECU gets proper feedback from complete sensor kit?

 

Update on this, it seems replacing the o2 sensor did help. But now it’s throwing a system lean code which is weird I thought it’d be running rich with the injectors

 

replace knock off BOV, boost leak test, fuel pump relay and tune.
with the mods you listed the car will make nice smooth power once its sorted out.

 

any updates about this ?

 

Yes! Update, as fair as the limp mode issue goes it’s been taken care of. The transmission needed flashed, currently using the 7% pressure pack, I tired the 5% and it happened again 7 is good.

The car didn’t have a stock rom but a messed up tephra just enough to run. Found someone to tune it for me and now it runs really well! Only issue I’m having now is it’s not getting enough fuel, going to replace the fuel pump and hopefully as is well from there.

One step at a time it seems
