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.
I want it. I will even PayPal a deposit in advance to help "Incentivize" the project.Originally Posted by antus
