    NEED BIN FOR 89 CHEVY 350 TPI MILD CAM AND HEADERS 3:27 GEAR

    Anyone know of a good starter BIN FOR 89 CHEVY 350 TPI 3:27 gear MILD CAM AND HEADERS that fits 1227165_16k_$6E ?

    Another question I had was where will I be able to change the gear ratio in the definition?

    It was suggested I use $6E instead of 32B because of baud rate and more friendly but now i won't have a baseline.

    I downloaded a few that are labeled 89 vet and 1227165 but not sure how generic they are.

    I'll keep trying with these first and check back.

    Thanks in advance

    Although the bins seem to be all labled with gear ratios there is nothing in the ECM to adjust for gears.

    Isn't it common for $6E guys with the old style MAF to convert to $8D Speed Density? I've never done a $6E car hands on but the guys I've helped were frustrated with intermittent data issues along with MAF issues. Data issues is all I remember about $6E...

    IIRC that is also an ECM that can convert to the Aussie $12P, or Dynamic EBL.
