Please help tune w/ 650's, Maf-T, S-AFCII

[project_tsi]

I know 650's are hard to tune w/ out a chip, but I've heard it can be done. Mods are 50 trim, Large FMIC, 255 HP pump, AFPR set to 42 psi, FIC 650's. Maf-translator V.2, S-AFCII.

Ill be honest, I know almost nothing about tuning, and I've read almost everything I can get my hands on. Basically Ive just been monitoring knock, fuel trims, and EGT guge. I set the Maf-T to 650cc injectors, and have been basically been playing around w/ the S-AFCII settings. The car is just running PIG ASS RICH. Could someone please help by telling what I need to be looking at on the logger, and maybe a basic starting safe point w/ the Maf-T and the Logger settings for 650's. Something so it wont run pig rich. I dont expect it to run top notch at all, just better than what it is now. Its like driving a Geo Metro. The worst bogging is about 2500-4500 rpm's. Also please no flaming. Ive read alot about tuning and it doesn't seem to help me. Would getting an Eprom chip w/ injector compensation for 650's help out tremendously, or more of last resort?
And Basically, what should my initial starting points be using BOTH the MAF-T and the S-AFCII? Or should I only be using one or the other?
Thanks, Dan

Alright you should look on your logger all the fuel trims. Adjust the BASE knob to keep the total trim between 80%-100% during steady state driving 35-45mph. If you wanna lean out the fuel curve set the AUX/BASE to a larger injector size. after you lean out the whole fuel curve you can add fuel where its needed. I personally just tuned everything with the MAFT. Try to keep your trims between 80-100%. Hope this helps a bit. good luck
