Hey
ive put a ct26 turbo ( i no to big) on a stock 4ltr . Running stock comp and stock injectors atm . it idles fine and free revs without a problem but as soon as i take it for a drive , it cuts the motor out at about 3100rpm as if it was in safety mode or if the spark in getting blown out ?? i have got the blow off valve set at soft. wat am i missing ? Cheers |

When the standard map sensor sees boost pressure it cuts the engine..

How much boost u running ? Usually around 10 psi it will cut boost , since you have a au you can put a 2 bar map sensor on.
You will also need a 12:1 fmu to increase fuel pressure , it would be running lean

Pretty sure u still need to keep the fuel reg hooked up for the car to actually get fuel .did you plug the vacuum hose for the reg .? If not boost will be coming out of the vaccum hose . At least get a 12:1 fmu . I have one if ur interested .

I have one if ur interested . this dodgey set up is for this weekend only causer it ment to be at a show . i got intercooler, tune etc coming but wont be here in time .. so that why we diong this..the vaqccum line tgo reg is on boost gauge . i normally have that line blocked off to fuel reg , goes harder with it unplugged.12:1 fmu what is that . ( sorry sounds like a silly question) |

au map sensor will cut fuel/spark around 2 psi...you need a xr6t map sensor and the ecu will need to be flash tuned. otherwise i can see big problems ahead...
also you should have vacuum line connected to the fuel reg as the fuel reg will rise fuel pressure as boost rises at a 1:1 ratio,,, |

So did this guy grenade an AU motor for s**t and giggles, fix it or just give up?

In series 1 AU's there doesn't seem to be any ignition cutout on boost - there wasn't on mine, I ran my Raptor kit quite happily without the MAP cheater. Series 3's definitely cut out on (around 2psi) boost, not sure about series 2.
