Well what the hell kind of response are you looking to get saying something like that? And if you don't like it so much, give it to me, I'll take your crap off your hands.

Well if you're running just the S-AFC with no upgraded injectors or fuel pump you can't expect it to somehow just add more fuel. If your injectors are already maxed out just adding the S-AFC won't somehow create more fuel, you need to upgrade the rest of the fuel system and control it with the S-AFC so you don't run rich at times when you don't need the bigger injectors spraying at a duty cycle the 550's (that your ECU thinks they are) would need to be at to give enough fuel.

If you can't tune an S-AFC, you can't tune a Haltech.

Good point about the fuel. What are you fuel upgrades?

the S-AFC will only control a percentage of what the stock computer does. so it couldn't smoothly control injectors over lets say 850-900 CC. 720's should be enough for you to run. Low 13's high 12's. It's not a piece of ****. Learn to use it.

I have the 720cc secondarys... 550 primarys... I have the 255lb/min fuel pump... can someone persay help me set up the sensor types... I think thats whats ******* things up.... every sensor is on 01
on high and low....

I have a 88' 7 TurboII

T3 turbo, bigger injectors, and bigger fuel pump...


Any help?

I just need this to last me until I can get the haltech. Otay said he would help me setup the haltech :-D
(but it comes pre-programmed)

Maybe I can call you, or you can call me, and you can perhalps walk me threw the sensor settings... and what else i might need to know... I have the fuel curves pretty much setup pretty nicely....
