    Default Help with cos3

    I just switched to cos3 and cant seem to get on the right track. The start of this tune was a tune that I have been running for months that was pretty good except for high boost. The engine is a stroked 6.0 truck block 6.7 now with l92 heads, vortech supercharger, long tube headers, no cats, 65lb FAST injectors and TR6 plugs. I just need some input on what to work on my A/F is way lean right now. It may be a little while before I get back to you guys as I am on my way to SEMA.

    What size map sensor are you using,(3 bar??)
    Ve table needs a lot of work. There seems to be an issue with how you are filtering your data judging by the looks of this table.
    A0001 & A0002 are out of range. Set these to 99%, save file,close file reopen & then set to 100% & save again.
    It wont hurt to post some logs up either.

    Iam using a 3 bar map. I dont have any good logs for the current tune, as I made some changes tonight that seemed to help and I don't have time to go for a nice drive. I can have some logs next week. Thanks for the help.
