Thread: Lean spot MAF around 5150 hz

    Lean spot MAF around 5150 hz

    Trying to get an OL MAF curve & I'm having some grief in around the 5150hz area. No issue I'm aware of above or below this area. I actaully thought I had it resolved in the screen shot. Just prior to the cursor I'm throttling up thru the MAF & run thru that 5000hz area just slightly rich, then where the cursor is it goes lean. I pedal around the spot as I don't want to run to lean, the same freq area's that were just previously slightly rich have gone lean. The injector pulse is following the rich lean spots. Then as strangely as it appears it goes away.

    I've attached a screen shot of the issue as well as my MAF curve from hpt. Any thoughts or ideas would be appreciated.....Tx's

    It is NW 102 on a ported Fast 102 with a Haltech C5 Super Bee using a LS3 card MAF
