2002 civic si hard acceleration issue
Posted: Sun Oct 01, 2017 7:23 pm
I'm new to this so please don't flame me for what may sound like a stupid question. I just bought this car and i'm trying to get it to run like it did when i bought it. the data logging wasn't working, so i erased the ECU. upon doing that i was forced to put a new map on. I tried the stock map and the car wouldn't even start. i tried the dyno tuned maps and the car runs but under hard acceleration it hits a certain RPM and it feels like i threw an anchor out. It just stops accelerating. I made sure the "lean protection" was on. I tried closed loop, no lean protection and a few other things. Any thoughts on what it may be?
Thank you
