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

Apexi SAFC

SAFC? Jaycar DFA?

awesome will look into it boys...thanks

No problem it will give you more power aswell get it tuned correctly and its a good bang for your buck!

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.

IS the SAFC II a better option or no real difference???

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)..

thanks guys for your feedback, have taken note of all of it.....later on will budget for power fc...thanks again

get a second hand powerfc fork out the dollars bro its well worth it
