    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.

    This is what I'd really be interested in, namely the PCMs for the 60degreeV6 family, 3100, 3400 and 3500.

    Is there a way to use an LSx PCM on a V6, such as a cylinder select scaler found in older code?

    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.

    I've only seen the 3x crank sensor system with the 4.3 liter V6 / '0411 PCM. The challenge I see with a 60 degree V6 per cylinder coil ignition would be designing an 18x crank sensor system. Attached is a .bin form a 2001 Chevy S10 4.3 liter.

    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.

    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.

    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.
