Goodbye MAF
Spent a few hours converting over my ROM and trying out a few iterations based on some stuff I had seen posted online. Initial impressions: WOW! The car is so smooth. Idle is ROCK solid (albeit a bit high, gotta work on that, 1300rpm), and any stuttering/bucking I had while on the freeway before is GONE. The car is SO smooth now its amazing.
A few notes:
-It took a few iterations to get the car to start/idle correctly. It wanted to idle in the 11's and load was way high. I got one that would work ok, made a few trips around the block, and all seemed decent.
-initially I set my WGDC all to zero. No boost! I'd hit about 9-10psi and confirmed seeing AFR in the 10's under 'boost' before trying anything more. No alky on or anything yet. Baby steps.
-Made a few more iterations to the SD maps this AM on my way into work. Tried a bunch, with mixed results. Ended up going back to almost exactly what I had the night before:
-turned up boost to about 19, just keep it simple. AFR in the 10's and high 9's (I used my old afr map from my tuned rom @ DB Performance) and while it is SMOOTH as silk this new rom has lean spool completely disabled, and i don't think my previous one did (my bad).
-Got all the way to work and got CEL for fuel trims. Oops, forgot to log those, even though I had been watching AFR all the way. low/mid are -12/-12, so now I need to try and figure out what to do to fix that.
-lastly, the car wants to buck if I leave from a stop w/o revving it up to ~2000rpm. It would do this before, but I'd give it more gas and away I'd go. Now, it looks like it is leaning out as rpms drop to ~500 and then I need to feather them back to life. Not sure what's causing this, but I'm sure my messed up fuel trims have something to do with it.
