    I'm confused. Are you out of injector, and what is up with the 3 7000 rpm columns?

    thank you for pointing that out. i seriously did not see that. i have to figure that out. i think it is because i made redline at 7000rpm.

    Ron, if this auto tunes an it is putting what it thinks it needs in the cells, you could be out of fuel pump. Check your FP if you log it and see if it drops.

    i don't think it drops. i have the magna fuel ProTuner Series MP-4301 and 160 lb injectors, actually i have had the engine happy to 110 kpa @ 4800 but after that it goes lean. im going out after work, running the numbers up and making a few runs. i will keep you posted.

    Ron, if you could take a screen shot of your a/f chart would be good. If the numbers in the map are VE % I think they are high. I am not familiar with mega squirt but ve is ve and a/f is a/f.

    I understand.I made some changes to my fuel map I limited the kPa 175 and now the RPM starts at 800 goes up to 7500.and there's not 3 7000 rpm rows. can you text me your phone number and I'll send you a picture of it.that might be the easiest.oh that's right you can't put phone numbers on this forum.you can send me a private message

    I did eliminate the fuel map above 175 because I don't think I'll ever go that high in boost

    I have no way of looking at ms logs. Your VE % seems extremely high. The last time I messed with VE based tubing was when I had a fast xfi. You are probably better off calling MS and see what they say.

    255 is the max value allowed on a VE table period. (8 bits is 0-255)
    If you have enough fuel pump and injector, the required fuel calculation needs to be changed.

    Looks like you need to check the Multiply Map setting to bring the boost cells down.

    i can increase the calculated required fuel. right now its at 5.2 because i use e85. if my car idles at 76kpa do you need anything below that (on my ve table it would the lower four rows)
