Default what am i missing???

Now that I've got that burst knock issue resolved I'm working on VE...

Keep in mind, I still have long and short trims enabled.

I'm trying to lean out my cruise, I'm seeing 14.5-15.0 on the WB, I would like to see closer to 16.0.... Under boost I want to be 11.5 to keep safe. Right now, I'm still in the low 10s. I've added 5% where I wanted it and no change... Then I went back and took that back out and took 5% more out from where I started... No change on the WB.

My idle is a hair lean in the high 15s but I can live with that for now. What am I missing??? Am I going the wrong way with my adjustment? Adding % leans and taking away richens right??? What the hell lol....

Thumbs up

I am not at the laptop right now but your maf must fail
Set maf max fail freq. to 0 and make sure you have your p0103 code enabled,either set the code to no mil or leave on first error,make sure the box still has the check mark
Copy your high octane table to your low.when the maf fails you are running on the low octane table
When it throws the p01 3 your mad has failed and that is what you need
Higher values equals more fuel and vice versa

I'm using the 2 Bar SD operating system... Maf is already off... I'm talking about getting fueling right... I've already copied my spark table over to the low octane table... I'm not quite following you there.

Dude, you gota turn off the trims to run stricky off the VE table, other wise the O2's are correcting the changes you made.

dont forget to reset the fuel trims after you shut them off otherwise your long terms will still be in play.

Didn't know that, ill do that in a few minutes...

I had them both off but had to go in and set the closed loop enable ECT high enough it wouldn't come on. I'm idling mid 14s, cruising close to 16.0 and under boost it falls to about 11.0 in boost. Gotta play with boost enrichment some, but it gets better every day.

High Octane table to Low Octane table isn't necessary with the 2bar SD OS. It still uses the High table with MAF failed.
