[Diy_efi] Mopar PCM

[brian.trulove at charter.net]

Is this the same as the Tricom? They have a SAE J2534 driver on their developement page. If you're game I can send the DCX2534 application, driver, and a 00' Durango 5.9 bin for you to try uploading. My interface works for diagnostics (BR-3) from obddiagnostics.com. I've never taken it apart so I don't know if they're similar. A schematic is posted on the site though. I don't give up easy either so I hope you're interested in pursuing this.

Hmm... I bet the ones with SCI LOL...
I'm not sure, because SCI is normally done with just a MAX-232 to convert to
serial...
Heck, even the OBD-II is simple... I have the CarCode scantool from www
obd-2.com and it's basically a PIC microcontroller and a few passive
components, and it does all 3 modes (PWN, VPW and ISO-9141-2) Plus now it
also does CAN...  
I'm going to tap direct to the CPU's SCI and hook it to the adapter I built
for my HC11 Eval board and see what comes across...  
I know the HC16 is the master and basically does menial single sensor/output
tasks along with sending proper data to the fuel and ignition HC11's... 
Maybe there will be some insight there??
