I know my fuel management isn't the greatest but I never thought it was this bad. I just had a baseline dyno done on my Turbo LS running about 10lbs of boost. I have an intank fuel pump and a vortech 12:1 running off of stock injectors. At about 3 1/2 thousand rpms the Air to Fuel Ratio jumps all the way to 15 and stays pretty constant, we stopped the run at about 5,000 rpms. I wanted to hear of some temporary solutions just to get it running a little richer. I have some RC 310s coming. I can't afford standalone since I have an OBDII motor. Do you think 310s and safc may help in making it run rich. Should I keep the vortech 12:1 FMU when I add the bigger injectors, or is that too much pressure in the fuel lines when I get the 310s. Any advice would be great

run the hack, (440's vafc) vortech 12:1 sux. I cant believe it made it that lean. Mine was so rich that it stopped pulling above 5600. But i bet 310's with the 12:1 and a vafc would work too, i would rather go with the hack though. But also i dont know if 10 psi is to much for that set up??? mine was at 7 when it was richer than hell, 10 might be leaning it di you try less boost at the tuners???

 

Nope, the spring's lowest boost on the wastegate is 10, but i just bought a 7psi spring and will get that in there too.

 

check my sig for advise on how to temporarily run richer.

(hint) The map sensor......

 

You know I think I may try that and see what happens.

 

Let me know if it works......

 

Its just gonna force it into open loop mode. Some engines dont run to well but it should be richer .

 

Here's a link to my A/F Graph so you can see what I was talking about. You think it's possible my FMU is not working right anymore. I have about 10,000 miles, is there any maintence that needs to be done to a vortech fmu. Let me know if the link works or not too.
