DW 555's

Alright the problem occurs when im coming off of fuel cut after shifting and i let my foot back on the throttle, the a/f shoots down to about 10:1-11:1 then slowly creeps up to where it should be after about 4-5 seconds, 14.7ish while cruizing. It just goes from 20.9 (fuel cut) and while comeing down it goes right to 10:1 or 11:1, then progresses up to 12 then 13 then 14 or 15.

It wasnt doing this when I had my 370's in and I am pulling a little fuel in the vaccum boxes on the emange map i/j adj. Kinda weird. If I pull any more fuel at the cell that I hit when i come off fuel cut, it will be really lean at idle. I guess I can try pulling a bit more fuel and see what happens.

Anyone have any ideas ??

Curious to know because I'll be inserting my 555's after EU install. Keep me updated about your outcomes. Thanks.

 

Without EU. my A/F goes from 21 to about 12-13.5 before back to 14.7 again thats with no EU and I have DW 500cc. Could it be injectors dumping fuel?

 

I figured out the problem.

With all that raw gas I was kicking out when I was trying to get my new motor started without lagging my injectors I must have really messed up the setting on the WB. Re-Calibrated the Wideband 02 sensor, and its perfect. Goes right to lean during Fuel Cut, and only goes to about 13:1 before it goes back to 14ish after I get back on the throttle.

I knew the readings were screwy. Wayyy to much fluctuation
