Inj Const, Knock at PE with 128blm? what gives
I thought I had found the proper injector cont and adjusted the battery tables as well for 19# southbay and a 88 MAF 305 auto. See earlier threads below I tried 19-20 but after 1 run I was very lean. I kept the battery table the same as my earlier edit (all increased) but lowered inj cont back to 17.
That worked, I was 121-127 INT and BLM across the board BLM were rich but even at MAF table 1-3 until AE/PE kicked in
I disabled PE and saw that MAF 3-4 also ran at 127BLM across the cells.
But I am seeing around lv8 160-200 at 2000 RPM and in PE above 2.2volts TPS above always have knock around 1-2 degrees. with OE disabled I do not get any under 2 volts.
My NB O2 without PE is reading 920-940mv with lots of PE enrichment I hot 1000mv in PE.
I lowered timing back to 6.5 degrees, I have noticed i have EST 42 erroe set in the datalog but I do not get the check engine. I disconnected battery but still there. This timing issue was there before the est error though.
So is it safe to turn off PE enrichment and drive with full throttle stabs for testing? Can too much bog/fuel at AE cause knock? can I disable the knock retard in the bin as a test?
