5.3 lm7 12212156 manual tune file

[soffenbecher]

I have had success with modifying the attached manual .bin file into a custom 5.3 manual .bin file.

I use TunerCats to copy / paste 5.3 parameters, not segment swaps, into the manual flash.

One of the challenges I've noticed with a custom manual 5.3 flash is the Deceleration Fuel Cutoff (DFCO) parameters. Automatic transmission vs. manual transmission requires very different DFCO parameters.

I often leverage a stock flash that is as close as possible to the custom flash I'm working on and change the essential parameters (fuel tables, spark tables, and MAF tables).

I've also noticed using a VSS is a very good thing with a custom manual flash too.

I have a jet boat with a 2002 5.3L LM7. Since I have no transmission would this bin work with my application to remove the transmission settings? I am currently using a stock 5.3L/4L60 bin.

I don't have enough "marine" experience to provide an accurate answer.
