hey, obviously im new to the forum, but i am at my length of knowing what to do about my car. if possible, please only reply to this information with helpful stuff, i dont care to hear opinions, just solid fact and tech data. here is whats going on. i have a 2002 honda civic si. amongst many upgrades i just upgraded to a rev hard turbo system. here is the thing, the guys working on my car are knowledgable and have done turbos before, but even they are having a hell of a time trying to get my car to work. here is whats happening. basically the car jerks and seems like there is a problem with the gas transfer because during driving and turning the car over is hell. they have got it to run without boost and said it ran beuatiful, but the same problem remains, o2 sensor and all. basically, the guys in harrisburg dyno tuning said they thing the reflashed computer is the problem. they think somehow the computer codes are screwed up and thats whats cuasing all the problems, that or the spark plugs, but i dont see why it would be the plugs because they are practically brand new. does anyone have any clue what might be going on? does the computer theory make any sense?

 

its obviously and ecu/rom problem
what fuel/timing management are you using?

my eyes hurt after reading all that; enter is your friend

 

ECU reflash, probably hondata? maybe a problem with wideband O2 sensor correction, or not being disabled.

sorry bout your eyes . i checked a couple other things as well. at the moment the only fuel timing is with whatever is part of the reflashed ecu, i dont have a seperate unit or piggyback, although the AEM one seems kinda nice.

after all this stuff is taken care of, we are bringing it down to harrisburg PA to have it tuned, and are also putting a VAFC-II on it, but thats not on yet.

from what the guys at the shop said, it was revhard who reflashed the ECU, it was the EP3 system for the k20 engine i believe. i heard a few things about revhard not being the best with software, there hardware (turbo's and stuff) were fine. but maybe there reflashing job is somthing that has happened before. for all i know though, revhard could be just sending it to hondata.
