Ok I logged my car a few weeks ago and was told that I had a boost leak, so I finally got around to fixing the leak and tested it. It is still low peak timing and I am still hitting fuel cut.
rpm/o2/timing/air flow
2304/.84/14/6.12
2596/.87/10/8.22
2912/1.00/10/10.96
3288/1.00/6/16.32
3748/1.00/5/19.05
4276/1.00/7/22.68
4828/1.01/8/26.27
5340/1.00/11/29.95<----already exceeded pre boost leake rpm and airflow
5868/1.00/13/32.80<---- hit fuel cut at 3.72lbs/min more airflow then pre boost leak
6203/1.00/30/9.10
4608/.62/26/5.28
Whe I nail the throttle the timing it retards to is a little higher then before, but peak timing is still the same 13 btdc. Airflow has increased since I fixed a boost leak, but my timing is still too low. I have my boost controller set at 14psi and it creeps to 16-17psi before hitting fuel cut. I have been told that 30-32 lbs/min are what the maf reads max before cut so I think Im doing alright there, but why is my timing so low? thanks for looking
