Just started tuning in Jan 08 so please bear with me...
The problem is that the car is rich at idle and a lean when cruising. It's got a S/C on it with SVO/Bosch green top 42lb injectors and a Racetronix fuel pump. Stock MAF w/screen.
What I've tried so far:
1) B4001 The IFR table is dialed in according to the injectors.xls
2) B3701 The Inj Pulse Width Voltage Adj table is dialed in. Got specs from Ford to adjust this table. The car was VERY lean in the 35kpa and up columns before bumping up that table. Tried pulling down the 30 kpa and under rows and it didn't make much of a difference.
3) B0101 Been tweaking on the VE table based on LTFTs and it's made a lot of difference in the 35kpa and up trims, but almost no difference in the 30kpa and lower under 2000 RPMs.
I noticed that my Injector Pulse Widths at idle have had a range of 1.892 to 2.107 ms. I can't seem to get the PCM to command a pulse width shorter than 1.892 ms even when the injector can do 1.13 ms!
I know, I know. I need a wide-band and do the AutoVE. I'm getting one in a month or so, but the car's inspection is out so I need a quick fix just so I can get it inspected. Right now, you can just smell the fuel when it's warmed up and idling. Any one have any ideas?
Thanks,
Dan
