    7427 MAF 4L60E Bin

    BLUF - I need a $0D .xdf file running MAF and 4L60E

    My 700R4 decided to eat its internals. Not sure if it was miss-adjustment of the TV cable or what. I've decided to replace it with a 4L60e since the 7427 computer can run it. Searched high and low for a .xdf mask that has both the 4L60E and MAF code in it. I've found bins that have either the MAF or 4L60E parameters in them but not both. If someone has a file I'd appreciate the assist.
    Thanks

    Thanks to Dimented24x7 I got this to the 4L60E and MAF combo to work. The key was starting with the correct $0D MAF bin. The original MAF bin I tried didn't have the 4L60E shift code located at hex address AD48 (03, 02, 00, 01). Changing the code on the original bin only caused the motor to run real rich. The other key was running a twisted pair of wires from the VSS sensor to pins F2/F3. If your speedometer doesn't work, reverse the wires. Below are the starting BIN file, XDF/ADX files for a three wire Vortec MAF.

    Bin, ADX / XDF files.

    Couple of folks hit me up for these files. Again, this is Deminted24x7 and Fast355 sourced info. I'm sure others aided this conversion in the past. These files use the vortec 3 wire MAF sensor tables. I've tried the 5 wire but it didn't run right. This project is on the back burner as I waste time trying to get a Luv pickup running. I'll try to get on here more often as I get back to this project and my LT1 (90s style) nova project.

    I have not looked at the files, but I noticed the .bin file size is 32K. The stock $OD .bin file size is 64K.

    I'll rescan the chip and see what I did wrong. Thanks Dave.

    I keep getting the same 32K result. Here is a file that was labeled from last Jun. Before today, it was the newest one I have. Organization is not my strong suit.
