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.

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.

Please, don't use the files posted above, they are garbage. Here is a BIN and XDF file that will work. This XDF has a 3 wire vortec MAF table in it, however, I'm running this bin with a 5 wire 5.3 MAF and it runs. If you want to run a 4L60E and MAF the key is the code located on the line that starts with AD40. AD48 is the start of the 4L60E shift parameters and needs to read 03 02 00 01 (view in HEX Editor). If your BIN doesn't have that, no amount of table tweaking will get the transmission to work. The first BIN I posted did not have the correct code in it. Hope this helps someone.

Does the knock sensor work on this? I tried to re-enable it and built a bin from the source code. But i haven't tested it yet.

[halljam70]

I believe it does. I never messed with the underlying XDF file other than change the MAF table to a 3 wire vortec MAF.
