I am pretty sure there is some floating around for OBD2 cars but I wanted to know if anyone has heard of anything for the OBD1 cars. Thanks.

I've been searching for that also....
I haven't found a thing on it yet.
I guess there isn't much of a market for it.

a friend of mine is into that kind of stuff. he and another guy were working on that exact project (lt1edit for palm pilots), but they figured there wasn't a market for it. if people are interested in this, reply to this post and i will call him tonight and have him read this.

 

I was thinking more of a scan tool. Maybe something that could log a small run. Shouldn't be too hard to adapt something along the lines of freescan to the Palm OS.

I did a little research on this.
What I have found so far is that prior to OBDII auto makers were free to create any kind of language for communicating with the ECU.
This means that there may not be any published data on OBD1 computers because there is no standard that must be followed.
The only way that this could be done is to reverse engineer the ECU.

This is what others have done, ie Andy Whittaker and his free scan.

Now if some one can find information on the ecu or even open source similar to Andy's software, we can get started but if not there is no point in developing Palm Software if we will never be able to get it to communicate.

Edit: To Clearify, I don't know for a fact that Andy reverse engineered the ECU but he obviously has more information than I do on the ECU

I believe Andy's Freescan software was originally developed for the Lotus ECU's. I don't know why or how they are basically the same as F-Bodies but the software can be used for both. Maybe Lotus's ECU programming is open source and scanning software can be developed from that.

I would definitely be interested in a scan tool for the palm os.

I would be interested too, I just bought one!

 

I have a Palm. Some sort of scan program would be awesome.

 

I just did an OBD1 conversion. I'd be interested too.

 

I'd be intrested in LT1 edit and scannmaster.
Thanks Ben

 

Are there any new developments in this? All I can find is OBD II.

 

Brainhart, what did you find for obd2?

 

I'd love to get palm software/tuning for the OBD1 as well as a generic OBDII scan tool (friends/familys other cars) to run. I already have a scanmaster, but being able to tune it at all would be awesome on a palm.

 

I just searched Google for OBD I Palm Diagnostic, and found a ton for OBD II on Palm, but no OBD I. Here is a link for OBD II sites if you want.
