He and another have designed and built it, and put the code for it in pcmhammer. I have used my AVT, MDI, a Mongoose, and an OBD-Link-SX, as well as the allpro, though the allpro turned out to be a non-starter as the guy who was making it stopped making it (Without knowing his reasons I guess it was too cheap and not worth his time when the non-hobbyists started lining up for them). If your using a J2534 interface you need one that works (sounds obvious but some of the super cheap ones dont work well, and the tactrix doesnt support VPW so cant do it either). The genuine vx-nano works well at a low price, but some of its clones do not. Obdlink-sx works, but is very slow compared to other options.


I have an obdlink SX (two of them ,actually; one stock and one from Trifecta), and cannot get it to do ANYTHING with PCM hammer. I gave up on it months ago. Any tips on what I need to even start playing around with it? Is the source available as well?

[Edit] Just read on another thread your Pcm is a E78, that ECU is not compatible with PcmHammer ...

Please try PcmHammer 12 and then attach a Full debug log to a post here so we can see was up ...

The source is here: PcmHacks.

Pin 58 and 59 are tied internally so either works. That's a nice drawing in your link. I kept a copy :)

Horsepower determines the speed you hit the wall. Torque determines the size of the hole you make.

Hi all,

Are you sure the data line from PCM is connected to DLC pin 7?
If so, it should be on pin 2 instead.
