Is it possible to reprogram the ECM with HPT as HPT supports the E67 ECM?
Complete kit with ECM, harness throttle pedal from Speartech $1695
Same kit from GMPP $815
The difference in price is quite big between the two kits.

I'll swing it by a shop that tunes LSx stuff and see what they say....

Not if it is not even in the programming.
Some of the cruise control systems on the LS2 engines is 1 wire that picks up different resistances from the C/C stem. Not 4 or 5 wires like it used to be.

Is there any way to get the install instructions for this harness? From what I understand there are some specific guidelines for installing the MAF. Anyone know the details? I am also curious as to what kind of VSS signal is needed by this ECU.

this ecm is similar to one used on engines with the 6L80E, 6L90E transmissions. They control Engine Only, NO trans. These transmissions have the TCM (trans control module) built onto the valve body assembly inside the trans. It requires only a few signals from ECM and the TCM is programmed for shift points, lock-up, etc.
