Manual Swap XDF/Bin question

[greg82]

I use TunerCats not TunerPro for flashing PCM's.

With TunerCats, I start with a 5.7 LS1 Manual Transmission flash and update the engine parameters (fuel tables, spark tables, injector parameters / tables, and MAF tables) to the 5.3 Liter (copy / paste marathon )

Deceleration Fuel Cutoff (DFCO) parameters for a manual transmission are different vs. an automatic transmission, which is the primary reason I start with a manual trans flash.

Perhaps TunerPro has a 5.7 LS1 Manual flash available?

Can you screen cap some of DFCO settings? I'm starting with a BIN from a manual 6.0L truck, the issue I'm having is the engine is stalling when decelerating.

The route cause I believe is that I don't have a VSS installed and won't be installing it, I've read that lots of people have tuned around this just wondering what to change?

You could try seg swapping the transmission seg to your stock file

The 1968 C10 has a Digital Dakota 8K VSS installed on the 3 speed transmission.

I didn't need to modify any DFCO setting. The 8K VSS requires a very ODD pulses per driveshaft revolution number. For the 1968 C10 the pulses per driveshaft revolution was about 3.25 to equal 8K pulses per mile.

Thanks dave,

I'm hoping to do this without a vss, so I'll keep poking around to figure out what settings need to be changed in the ECU.
