Hi all,
Im having teething trouble with my b18ft the car is on the richer side of things somewhere between 12.8-13.5 of boost, drives well doesn't splutter etc. But as soon as she comes on boost AFR's shoot far left to the 10's
Currently im only running 8 psi on a T34, I dont know what the standard boost for the b18ft is but cant imagine its much more than that?
Injectors are standard, AFM hasnt been touched so im really struggling to see why its so rich
I could bleed of some of the pressure to the actuator but is this not just masking the problem?

Re: B18FT To rich
Hi Benji, standard boost is only around 6 psi I think.
I've got no idea why the car would be running rich tho sorry. The standard ECUs are suited for the T2 turbo maybe the T34 is sending too much air in so the closed loop system is trying to compensate??? Just guessing

Yeah could well be a possibility. Going to adjust the afm and up the boost to see if it'll lean it off a bit

Re: B18FT To rich
Well done getting a T34 on there though not many of those about on a B18FT. Maybe a rolling road session might help you for some better advice.

Yeah man, it's probably what I'll end up doing?
Are you the same Jamesy that's just bought the turbo2 on rtoc?
