Re: AVR to Arduino - VPW
Interested if you could post a schematic of how you connected everything in your arduino implementation. Trying to get this to work right now myself.

Re: Sending bus commands
The first part of this project is to get a dash running in a car with a different PCM from a different vehicle. (01 Grand Prix going into a 99 Grand Am). I am trying to take the analog values that the Grand Prix cluster receives and "compress" them into Class 2 data so the installation of ...

Re: Sending bus commands
Honestly I'm focused on just commanding the IPC for the moment. If that project gets off the ground I'll have a bigger green light for more complicated projects. Also if I was to make a standalone programmer type interface in the future, I'd make a custom PCB for it. I'm really trying to stick to th...

Re: Sending bus commands
There is a need of a low cost vpw interface that can handle large packets (> 1kb) and can switch to vpw 4x speed for vehicle programming purposes. If you were to build your own, document it publically and/or sell it cheaply and if it could send and receive whole packets at vpw 1x and 4x it would ge...

Re: Sending bus commands
I have at my disposal HPTuners and a cheap eBay code scanner.
I was looking at using a Bus Pirate (https://www.adafruit.com/products/237) to sniff the data transmission lines.
Any suggestions for a device?

Re: Sending bus commands
What would be the best way to listen to the bus traffic? Eventually I am trying to make this work on other GM IPCs and I have the complete cars available to check along with a slew of PCMs to bench test. I have a basic understanding of the ECUs innerworkings (thanks to you guys!) And would really li...

Sending bus commands
Hey all, new here but trying to figure some stuff out, not 100% related to hacking the NVRAM of a Delco ECU, but somewhat related. I'm working on controlling a GM IPC standalone without an ECU. I am trying to emulate the J1850 bus commands that are sent to the ECU over the Class 2 data line to make ...
