Has this been tried on v6 computers yet? If anyone has a cable available for sale I am interested.

Yes, it has been tested, but did not work. There is a possibility that v6 will be supported one day, but not yet.
The man who says something is impossible, is usually interrupted by the man doing it.
Seeing as how some 4.3 equiped vehicles came with a 411, I would assume so, but knowing nothing about them, I dont know how its done.
79 Jeep Cherokee, AMC 401, T-18 manual trans, hydroboost, 16197427 MPFI system---the toy
93 Jeep YJ Wrangler, 4.0L, 5 speed, 8.8 rear, homebrew hub conversion and big brakes, hydroboost, 2.5in OME lift, 31x10.50's---the daily driver
99 Jeep WJ Grand Cherokee limited, 4.0L, auto, 2wd, leather and power everything, 99% stock---the long distance highway ride.
I'm not worried about retaining the original ignition system of the 60 degree v6, and making a crank trigger is not much of a concern. My biggest concern is that the code is able to run in a true 6cyl mode without needing to fudge numbers or do any weird tricks to get the RPM and ignition side to work. I just don't want to have to switch to dizzy like the 4.3 uses.
I'll have a look at that bin later.

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:

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!

Any updates? Eta on software release and cable availability?
The project is still alive but there are no updates currently. Thanks for the interest, knowing people are waiting and want it helps provide the motivation to make time to work on it.
