AFR deeps into 10~11 when full throttle.
Hi,
my current tune on my pfc is quite disappointed as the mid and high end power is good. Knocks count under control but my major problem is whenever i full throttle on 1st 2nd & 3rd gears, my car AFR will deep til 10~11 which make my difficult to accelerate (or it hard to move/very very heavy feeling) until ive to always let the throttle off a bit and throttle again and only then my car take off with power!
I hv discussed with my tuner and he said my Pfc L-jetro type ecu is unable to adjust the lower rpm/load fuelling (hope i get it right).
Is there a way to overcome my problem?
Thanks

I m using a FC with Djetro not sure how big is the different... most of the time i would have adjust the fuel to a bit lean on the load from 1000rpm to 3000rpm which is around 12.30 to 12.80 AFR at that point... then when the turbo start to kick in i try to make sure the AFR is around 10.80 to 11.50.. by the way i m using FC datalogit to tune it...hope it helps
