tuning help , where and how too start

[d1verDSM]

Ok i would like advice from experienced tuners

I have

colt 91 200gt,4g63t 1g stock pistons rods, 20g , 660cc , 255 pump , for tuning i have , a safc (blue first one) a 2.0 mafT with a 3.5 inch gm maf in draw trew mode (before turbo) with a bov return and all.

i also have a innovate wide band witch can log Rpm , and tps , etc, but not knock

so my questions are , where too start ?

my maft is set with the pre settings for 660cc's now , and all the other knobs a zero out. the safc is zero out on low , and about + 5 above 3500 on high just too be safe.

So do i log my afr, and tune my maft first then finish off with the safc, or do i just let the maft at the base settings for 660cc'S and tune only with the safc ?

for the safc , how do you guys tune ? do you tune for low , and log at lets say a third pedal , and then tune for high at WOT ,in what third or fourth ? i doubt ill hook in third . i was thinking of tuning for 10psi (stock ) and then moving it up all the way too 20-23psi , is this the way too go ?

whats the optimum afr 11.4 ? 11.7 ??

any tips , ideas and comments are welcome

I would leave the MAFT at the base settings for your injectors and use the SAFC for the fine tuning.

for the safc , how do you guys tune ?

Read the above link and post any questions you may have later.

I would start a couple of psi below where you would like to end up. Starting 50% lower than your target is going to mean a lot of ongoing changes. I would recommend you start around 17psi and work your way up from there.

That will vary from car to car, but most people like to tune pump gas to 11.3:1.

Do you own a logger? Although a WBO2 is great, a logger/WBO2 combo is the way to go short of dyno time.

Let us know if you have any additional questions.
