i will as soon as i figure out how to use the logger . sounds dumb.. sorry but im new to this tuning shit. i got alot of ppl like keith(wiseman on here) and team trinity that kno what there doin' i just gotta get some hands on with the logger first.

like i said last time -20 across the board hi and lo i was still rich. but safe from what i could tell.. w/o the logger.

On 550s? That doesn't sound right at all. You still using 43psi fuel pressure (vac line disco)? Because you should be tuning your way from -14% or so to -18%. Your afpr may be set wrong.

But yeah, no one can help you tune without logs.

evo8(190) rewired fuel pump
550s

are my only fuel upgrades everything else is just like it is stock. so my afpr can't be wrong cause its stock not aftermarket. and it was just replaced about a month ago anyways.

I don't see a a/f gauge or wideband in your profile...how are you certain you are running rich at -20% on 550s?

The tuning spreadsheet here is really helpful for referencing your settings:

You shouldn't be at -20% on 550s without logging. -10 to -14% probably safer range to start.

how do i know im running rich? well im sure a few friends that road behind me can vouch for me . and the flames i shoot out the exhaust are kinda cool but i'd rather they go away thanks for the help!


A LOT!

im pretty sure i got the safc set at -18 right now since i put the 550s back in the car

Is Palm N stein a workable program for a 2g? i've heard mixed reviews about it.
