From what I've been able to deduce, previous tuners have tuned my car by adjusting the ifr table. Seems sloppy, but understandable given it's all been done via email without wideband information. I'm gathering this due to the fact that I've got fast/Bosch 36 lb/hr injectors and all ifr data I can find is in the 5 g/s range (it slopes due to the unreferenced regulator).
However my tune has it in the fours, about a full point off. Due to the fact I'll be OL for auto ve tuning, I'm concerned about how lean the engine will run once I correct the ifr table. Is this not a valid concern? I feel like I'll want to somehow adjust the ve table at the time I change ifr data to at least somewhat compensate for the lean condition I'll create.
Currently with my injector flow rate in the low fours, I'm running -3.1 and -3.9 ltft so apparently for the ifr table being wrong it's fairly close in closed loop
Given that I know my tune is sloppy, and I highly suspect it is running lean as is under wot, is autove the correct place to start? Am I to assume that I should adjust the power enrichment table before I begin to run in OL to ensure I don't run too rich?
Thanks!
