I'm running EcuTek and my car does this as well. It really doesn't matter to me as long as it's not causing any issues with my car.

wow that was an old quote. I'm on OFT tune now and it still pops, probably louder now with no cats.

Just did the -10 @.15 load in Base Timing B on a E85 tune. This is after just 10 or so miles of driving. Sounds like the Ken Block Gymkhana Fiesta under deceleration. lol

MAF voltage(and therefore engine load) is lowest when decelerating in gear. If in neutral I rarely hear the pops as of right now. Have only scaled my MAF for 3v+ so this may be part of the problem, but I suspect it will get better with time as yours did.

In ECUTek, what would be call the "Base timing B" and the "Primary Open Loop Fueling"?

They are just the main base ignition timing map and the main fuel map. It's quite easy to figure out

I noticed that you actually just changed the columns .3 and .4 to .15 and .3 respectively in the open loop fueling table. I'll do the same I guess as they are near duplicates anyways. shoot flames yet?

Anyone know if you can add rows to our ROM? I would like to add rows to the open loop fueling table.

Not in standard maps, no. You can rescale the axis though to suit.

Stage 2 E85 tune with afterfire here:

[ame="https://www.youtube.com/watch?v=8t-Tjm4XGTY"]FRS just the afterfire(edited) - YouTube[/ame]

Had to give just a tiny bit of throttle after revving to get it to work. Not sure exactly, but I guess I wasn't in the right load range. May do some logs of just revs and see what's happening.

Thanks! @andrew5826
