my issue is i have a 2000 integra ls/vtec running having to run on the ls ecu, the car runs but it sounds like a loud truck, is it possible to chip the obd2 ecu or would i have to get a standalone to make the car run smooth. the car is throwing a cel but i believe that is because it's using a vtec engine wire harness and because the ecu was not meant to work with a vtec head, any other opinions? flame all you want just as long as help is given i'll think of it as constructive criticism.

ok kinda cancel the running part but it should just be the throttle is not staying open enough at idle

if u have high compression pistons i think that ecu would fry your motor after a while. if the ecu is set up for hondata,chrome or whatever u can run what ever base map u want just have to activate vtec. to me obd-2 is to sucks *** anyway i would go obd-1. if your gonna run obd-2 i would get a vtec ecu and disable the knock sensor then you'll be good
