So the weather is supposed to start getting better down here (read: < 90 degrees every day) and that means I might be able to manage sitting in my truck without frying like an egg. You may be wondering why I would want to do something so silly as sit in my truck. Well, let me tell you!
I bought an OBD-II adapter so I can hook my laptop up to my trucks OBD interface, and I'm in the process of writing some software (using REALbasic) so that I can pull the diagnostic information. Basically, when the check engine light comes on, I want to be able to plug my laptop in and say "oh, this is the problem". The other cool feature is that it can tell me stats about how the engine is performing.
It's just been too damn hot this summer for me to sit out in the truck and do my programming, so I'm kind of looking forward to the "winter" down here so I can start back in on this.
What sort of cool things do you try to hack? Any success stories? Anyone else ever try hacking OBD?
ohh ohh...

Yes, but have you actually started that project? Gotten any results?
Haven't started yet.. a coworker and I have both contemplated... but we have to pick a platform, we're not going to do anything low level. Why reinvent the wheel? Basically... enhance what the other team (reference on my post) has done and make it more developer friendly than just a C++ API (Wrapper to specific) hardware.

I'm rebuilding my 1999 Dodge Dakota R/T for bracket racing. I purchased PDA Dyno to scan OBD codes and log data during a run. What I really want to do now is play around with air/fuel mixture, ignition advance, transmission shift points, etc. The PDA Dyno does not do that. Hyperchip makes a "tuner" for my truck that isn't very impressive and not worth the money. There is computer tuner software out there but only for Chevy. It is expensive but it is just what I want for my Dodge. So I took up the project of writing my own software. I researched the internet thinking there were hackers out there doing what I intend and I could then get some pointers, examples, shareware, etc. Nothing turned up but this posting and prj.perquin.com has a hardware interface (already have that with the PDA Dyno OBD to RS232). obdii.com has some info but again short on Chrysler and no information on programming a PCM.
I have programed in Basic since 1979. Presently using Visual Studio.Net. I have a spare PCM so I should be able to program in the shade. Would be glade to share information with you. email: dbarnett@servotek.com
