right was running stage 1 with yellows today i put a stage 3 chip in for l6,greens.
i fitted a set of greens with are used but told there in gwo there is no leaks from inlet.

i havent yet fitted a 3bar yet but i only just started the cosworth (dont worry i wernt going to drive in untill i have 3 bar) but on idle it has a missfire. would this be because it aint got a 3 bar fitted yet? i thought it would still be ok on idle

 

having the wrong map sensor fitted will completely cock it up.

the ECU is getting told the WRONG values

 

infact, your ECU probably thinks you're actually on boost

 

i dont think u should be doing this ur self.....lol....

 

ive done this before im sure just starting it for 30secs aint going to kill it
