R32 Gtr Fuel Presure

[PHA71L]

what should the base fuel reg presure be at?

r32 gtr stock fuel reg....

i have a sard intank pump and have re wired the pump

i was told it can make it run richer and have a higher base fuel reg presure?

as i now have a miss......

From memory, 43psi base pressure, vac line disco'd from reg.

ok thanks mate going in tomorrow now to fit a turbo smart fuel reg and check afm

[PHA71L]

ran it on the dyno found the miss! small leak in one of the inj rubbers!!

fixed that, ran it again with stock fuel reg after re doing the fuel pump wires very rich! 10 afm was about 13 befor up top in the revs...

fitted the reg and backed the presure off and a little bit more boost now making 336rwkw on 17 18 psi

up from 285kw on this same dyno befor the fuel pump wires and reg still needs to be tuned again yet tho

Just wondering, you found a small leak where? Are you talking about the injector insulators?

I miss the economy I had before I fixed everything, was getting almost 400k's to a tank, now lucky to make 200.. oh well. More fun now anyways.

bottom inj seal rubber...

really? i still get over 500km to a tank

How did you fix the leak? I'm fairly sure that a couple of mine may be similar.

Not a good tune, rich as, and a baby gtst size tank..
