i'd say the 4.3 stuff would control it reasonably well as long as a reference signal offset value can be played with. might have to reorder the injectors, but not much else.
copying all of the 60V6 tables into it..... that could take some time.

Still haven't had a chance to try the software but thinking about cables and cost.
Here is a link to pictures of a VPW programming cable:

This is rumored to be the same cable:

i would need to find the instruction set for the 68HC908, but that looks super simple compared to some other solutions i've seen.

Yep. Introduced for LT1 cars and possibly based on original GM Off Board Programming Device.
The only problem is the 68HC58 is EOL. But I bet it is still available somewhere. Its the VPW chip the pcms use, as well as the AVTs. Definitely the best way to do it. But not the only way, and still requires firmware, though a lot of code would be very similar to whats in the pcm. Ive been testing a mega 2560 based circuit with opto-isolators as a front end. Have the VPW triggering interrupts but its not collecting all of them so isnt usable. Still a work in progress.
Jayme has updated the AVT 852 ADX. It now supports 1x and 4x in the same ADX, can read trouble codes (DTCs), and supports wideband in the data stream via the AVTs ADC input where fitted. We have successfully retrofitted this to some of our cables, and will provide details. SMD soldering required.

Nice work! Too bad I could get this to work with the JTEC!

So the cable connects to the laptop via serial???!

Can VATS be disabled/VIN# changed with this software?

Antus, I am sure with christmas coming up your even more busy like the rest of us are, but I am going to ask anyway. Any updates on the flash version of the software?
@babywag: you can change vin, but not vats until it can write a calibration.
@mecanicman: Sorry no updates.
