adjusting fuel ratios without new ecu???
Hey guys
i am in the process of completing some breathing mods on my car... intake, dump pipe and bigger TMIC...with stock turbo for the time being. i have thought about just fully resetting the ECU??? Is there a way my fuel ratios can be controlled with out having to get a new ecu...just a mild fuel tune to prevent leaning out??? Dont know if what i ask makes sense, but yeah any feedback appreciated.. Thanks guys

adjusting air and fuel mixtures without having to get a new ECU? NO. You can do it with a piggy back solution though.
The ecu will adjust to mild mods by itself. You may be able to get away with using stock ECU for those mods you listed. I know of a few my99s running those kinds of mods and still on the stock ECU. The only way to know for sure is to get on a dyno as soon as the mods are installed. While on the dyno, get the operator to do a AFR check and also knock sensing. Just remember that with those mods, a freer intake and exhaust system may cause you to hit boost cut in higher gears. So I would be budgeting for a new ECU anyway. For such mild mods, a Power FC would be a good and affordable option.

SAFC is only Air/Fuel - Power FC is full replacement. Power FC will be better. They're about $1k + fitting and tuning.

see how how car goes with just the SAFC, as i am more worried about preventing it from leaning out (even more)..
