r33 gtst AT with z32 ecu rb25det over fueling fault
Posted: Sun Jan 25, 2015 7:00 am
hi wonder if anyobody can help me ive done a map on a r33 rb25det AT spec2 with z32 ecu
i have a fault with over fueling when i set the fueling at idle (kconst at 175 ) it idles very badly hunting and under fueling if i correct this at idle it runs fine but when i start to run it up on the dyno it is off the scale on fuel ive checked the file against others and the only thing i can see that does not look write was the enrich (warm crank) was of the scale very very high any help on this would help thanks
and its an auto gearbox does this make a difference to base image
kconst is 193
injection latency 530
fuel is good under boost
hesitates when on low rpm 3000 rpm when you put your foot down (this could be mapping needs more work)
and hunts now on idle and cant get fueling write at idle with out messing up the rest of the fuel map when adjusting kconst
any help would be great
regards fred thanks in advance
