Hey guys i have a obd2 USDM gsr Motor, and my tuner sugested i barrow this JDM ITR ecu he has to see if it helps any, well i did and the pull of the car feels totally different..

Now i know the stock Gsr Intake Manifold has a secondary butterflies, which on the stock Gsr ecu opens up at 4400, and than vtech hits at 5700ish. its like i have 2 stages of vtec, the car pulls consistantly, pulls a tad harder at 4400, and even a bit more of a pull at 5700ish.... With the Gsr ecu controlling the butterflies, it felt like a constiant pull...

SOOOO with the JDM ITR ecu in the car, the car feels ok from low rpm, but dosent seem to have the exact same pull like the gsr ecu had (partly because i dont think my butterflies are being opened). But once i hit around 5800/6000 rpm's vtec hits like ive never felt before with this ITR ecu....


Ok so im ending with that, the GSR ecu has more low end (butterflies) pull and less of a top end pull, and the ITR ecu has less low end but a much strong top end..


Do you guys think im getting any avantages with this JDM ITR ECU, becides that it dosent have a secondary o2 sensor. is there anyhting i can do about the ITR ecu not controlling the butterflies, like somehow open them up all the time?

or should i ditch it and stick with m stock and save for a P28chipped

Oh and i know a dyno will only give me a true answer but im broke haha


PLEASE HELP MEEEEEEEEEEEEEEEEE THANKS H-T!!!!!
