The first Edge Juices have a feature that I would like to do with EFI. When you switch back and forth between "tow/haul" and "normal" the power levels will change if they are programed that way. Can we do this with EFI since DSP doesn't work on the LBZ?

to my knowledge NO. sorry. The only thing I know that you can do is program different shift points for tow/haul.

TCM and ECM programming aren't linked. You have to run a seperate tune on the ECM for normal TCM mode and another for T/H TCM mode. You might be able to use the T/H button to activate a DSP2 portion of the ECM to have a different tune for each mode.

good luck, I posted on this some time back, and no one seemed to have much advice. if you could get DSP2 to work on your truck, you could use power from the lamp in the dash to switch on the coil portion of a relay, and thus switch the DSP2 tune in the ecm...just a thought. I was persuing this, but decided against it in the end.

Good luck,
Mike

Unfortunately DSP2 for our trucks wont be available for sometime probably if ever.

to my knowledge NO. sorry. The only thing I know that you can do is program different shift points for tow/haul.

How about the {D5196} table(six speed TCM). I haven't studied this out yet but is there a way to use torque management?
