for starters the file named "b adjuztment tune" (sorry spelling had to remeber unique name) is a tune that was done remotely.
the file "10" is my own tune that all I done was run hours of autotune and my ve table ended up like that.

I have a hotside mp62, dual tb with big tb at charger and stock in oem location with bypass valve and bov. fmic, fic 1000s, ls coils, jrsc header, bofi 2.5 inch midpipe and a RB dual exit muffler. stock bp4w as far as i know (charger installed years before i bought from PO. hope this is enough info to determine why my VE table is so odd. i dont believe i have any vacuum leaks i checked recently. but yeah this is strange. i am hitting my target afrs or close to it. car doesnt feel strange at all. also the table hasnt changed much from what the remote tuner did. can someone explain how im running 100% efficiency in most the cells?

Sorry correct myself. Not 100% efficiency but close to it. From all the ve tables I've ever seen there are greater change in the numbers but mine seem to trend around mid 80s to 110. Even after my final autotune session the numbers were trending upwards.

Those numbers are just a multiplier in the full pulse with formula. You can adjust your required fuel number to move those numbers up or down, for example, adjusting rec fuel up 10% and those numbers down 10% will have zero effect on the formula. Do some googling on the site, there are several threads on this. I have read that having those numbers take full advantage of the resolution canallow for finer transitions between cells. Honestly, I wouldn’t worry about it. Some good reading here: How MegaSquirt(R) EFI Controllers Work

Thank you for tue response. I have looked around and such and know about the fueling formula although I still have quite a bit to learn. I guess I wasn't so worried about the high numbers but the shape of the ve table with tue numbers being close together from 80-100. But you make a good point and if I think about it more the shape is almost similar to others I've seen just bigger numbers. Also yeah like you said my required fuel can be changed but for now I'm just going to go with it. I think it also has to do with my fuel system being that the nb is 60psi so I had to put my 1000cc injectors as a bigger flow to 1190. I'll just continue and try to get my table more dialed in then.

Looks like how mine did. 4500-5500 rpm is where it drops back to between shifts. then you get back on it real fast and it passes thru that area but the accell enrich isn't right. when you crack open the throttle fast it goes lean so VE tries to constantly add fuel in those zones. do single gear pulls slow on to throttle, should help.

@austin102085 the thing is I've tried steady throttle and I don't buy accell enrichment influencing this map. I even have a custom filter that disregards any rapid mapdot change and autotune filters out accel enrichment. Idk it's just odd. I'm having issues where on light steady throttle in those areas 4.5-5k I go lean randomly. I'm starting to suspect my iac is cracked open ever so slightly causing the lean conditions
