Newbie tuning ?'s

[Irrational]

Ok I have my gm and translator set-up and now trying to tune. Can some one tell me where I am looking to be at. Instructions suck and tried doing a search but just causes more confusion. I am hitting fuel cut and confused on why. Did a pressure test tonight and no leaks! Ok heres the questions I am trying to get the settings right so i no longer fuel cut. Where should my goals be for the settings Low trim? Mid trim? High Trim? and volts for o2? I know my target timing is like 18. Please dont flame I am just so confused keep getting told diffrent things so i am lost. any help would be appreciated using a dig- tuning pocket loger.

Hey my post is a little below yours "Maf-t" and i am having the exact same problem. The thing is though i dont have a datalogger till this friday so i cant exactly check my knock or fuel trims. I installed it on my car and every time it gets to around 4k rpm it cuts, then after that it cuts every 300 rpm or so. btw, where did you or neone else put the vaccum line for the selonoid that is supposed to be hooked up to the nipple by the plug for the stock maf?

Forgot my trasnlator is 2.02...is there a major difference between this one and .01?

You don't say what injectors you are running, but larger injectors with a MAFT *should* hold off fuelcut. But, if you have the base settings too rich, you will hit fuelcut sooner.
Your trims should stay right around 100. Not that it means much, but you usually want the O2 to be .90 to .92 volts at WOT. O2 sensors vary too much, so MAINLY watch your knock. Back the boost down, lean the car out, and watch the knock. If you see more than 4-5 counts, richen it back up slightly.
You will ONLY see 18 degrees of timing at 7000+ rpm when you hit the top airflow map.

Agreed. If you are hitting fuel cut, lean the WOT setting out one point, then do a pull in 3rd or 4th. Keep doing this until you no longer cut. At each point, you should feel the cut happen later in the RPM band to some degree until it is gone. Make sure you keep an eye on knock while leaning out at WOT.

thanks alot guys, what should my 02 read on my loger at idle?

Your O2 should fluxuate freely at warm idle.
