General EPROM chip, MAFT, SAFC, and car not running right

[93xsg]

My mods include, B16g, 650cc FIC, 3" GM MAFT (blo-thru), AFPR (stock psi), PLX wideband, SAFC, MMCD datalogger


So before I installed the chip, I had maft base on 6 (thinking it was v1.3) But I have v2.01 so that would be for 490cc injectors. On top of this I had about -10-15% on the SAFC. Car ran great like this. (didn't have logger yet, tho).

Anyways, installed a stage 3 eprom chip w/injector comp, maf comp and enhanced closed loop/timing from a freelancer on here. I set the base on maft to 2 (for 450cc), and 0'd out the SAFC.

Car is sluggish, turbo spools up almost instantly (like 2k rpm) and I go into open loop. AFR's are great and no knock but no power.

I put in the stock eprom and returned the settings to 6 base and -10-15% safc, and car ran just like before.


I'll get a log up soon, but just wanted to get this out there, see if anyone else might be able to point me in the right direction.


Stacy (guy made my chip) said it looks like I need more fuel. Lean conditions would cause faster spool up right?

haha thought I'd let you enjoy your weekend and stop bugging ya

I ended up just resetting ecu again and not ####ing with anything for a while and just driving it.

Its doing a lot better now, I think I need a little less fuel at high thr, but I added some fuel initially so I wouldn't blow anything.

Mid thr all the way through full boost is solid.


And low thr is still a little bit sluggish, mostly from 0-3k rpm. Ill get you a log soon stacy (by email), if you even check here again .



Ended up forgetting bout posting a log here anyways so it was pointless
