quick question -- block 032 -- is it bad if one bank shows slightly more negative for part throttle?
on the highway while feathering the gas i get about -16.4% for bank 1, and about -15.4% for bank 2
is that a big deal? i noticed one bank running a bit richer than the other before i put in k04's (about a year ago when i changed the plugs - one bank had more carbon on the plugs)
since a lot of minor parts have been changed, and this still seems to be an issue, i'm guessing the intake manifold casting for the one i got was just better on one side than the other - i doubt it's the injectors, since those were swapped since the last time i noticed one bank running slightly richer.
also, those neg % numbers correlate to the % that the ecu is bringing down the entire fuel map, right?
fyi, at idle i get about -1.7% (idle numbers) and at WOT i get about -2% for the part throttle numbers. as soon as i let off the part throttle numbers go back to around -16.4% for bank1 and 15.4% for bank two
oh, and these numbers are with the awe stage III kit. egt's at cruising (no gas in 3rd or 4th) are around 550C. at wot they don't go above 800C

Nothing at all
I'm trying to find out what the difference in housing diameter is between Bosch (2000 MY ) and Hitachi MAF. My Bosch internal diameter is 3". Doesn't apply to Forcefed at all, just to me, as I am considering Stage 3 kits and I have heard the AWE w/ Hitachi MAF conversion may be running rich. Just trying to track down some possibilities.

Housing diameter is same. The reason for change to Hitachi is a more stabe/reliable sensor. As far
as running rich or other problems, am working on a stage 3 A box install now. Will see how it works out.
