SAFC tuning questions with Big16G...

[gotdsm?]

Ok I tuned my car with an SAFC and a logger before I put my injectors in my car and my car seemed to pull really good. However, since the install of my RC 550 injectors I cannot seem to get the car to feel like it did.

Here is my current setup.

ACT 2600 Clutch
Big 16G Turbo
NGK spark plugs
NGK spark plug wires
Carbon Fiber Autometer Boost Gauge
Joe P. XZ Manual Boost Controller @ 15psi
Walbro 255lph High Pressure Fuel Pump
Apexi S-AFC
550cc RC Injectors
KYB AGX Shocks

I was wondering what type of fuel trims I should be running... I own a 91TSi AWD Talon. I dont have a logger right now.. I ordered the m100 off ebay and I am awaiting my loggers arrival.

Thanks!

You really shouldn't have installed the injectors and played with fuel control without the proper tools (ie logger). Hopefully you haven't done anything harmful to your engine...

I don't know 1g tuning as much as 2g tuning. But for tuning the lo safc settings for a 1g, you'll want to log fuel trims, rpm, throttle position. I believe 1g's have low, mid and high fuel trims. And I believe you want these to be dead on 100%. There are plenty of comments about this if you do a search.

For hi safc settings you want to log knock, timing advance and o2 voltages. You always want timing to advance; never retard. You want a little knock as possible, 0-3 I believe. And I think your o2 voltages should be around .82; but I don't know about that so find that out from another source or from a search.
