Lt1 tune by palm?
Lt1 tune by palm? i have a pda (treo 650) and wondering if you can actually tune a car by it or not? I know there is some laptop software and idk why a palm wouldnt beable to do it. Any help would be appreciated. Thanks
I tried years ago with a Palm III and my 94Z... I hit a roadblock with the Palm SDK. They kept radically changing function calls in the language so that programs didn't compile at all across different versions of the SDK... so I gave up in frustration. 
To my knowledge, nobody makes an OBD1 scan tool for PalmOS. Closest thing was Peter Ohler's EV1 tool, but it was receive-only (and the LT1 requires bidirectional interaction).

With megasquirt you use a Serial port...they have cable available thru several companies. Look on their site, they actually have one lt1 running on this SEM. site is www.msefi.com
Doesn't Tunercat have a Palm version? I'm running a free scanner for OBDII that you can download for the Palm. It doesn't have a ton of variables to watch, but it's better than nothing for free.

I'm not aware of TC having any Palm applications. He's got a pretty comprehensive list of OBDII applications for PC, and his well known listed apps for OBD1 vehicles, but (to my knowledge) not Palm.
OBDII on Palm for scan tools is a no brainer. It's pretty easy, as http://www.multiplex-engineering.com sells reasonably inexpensive hardware interfaces that communicate RS232 to OBDII. From there, it's just a matter of tweaking a comms package (at a standard 19200 baud rate) to interact with the M-E interface. Palm has 19200 as a standard baud rate, so that's no problem.
The problem for me is with OBD1. First up, it's 8192 baud, which is 'odd' for regular serial ports (most operate at standard multiples of 1200). I think the Palm serial port can run at that speed, but I'm not certain how well. Then the issue becomes writing the software to interact with the datastream. Again, to my knowledge, nobody's done it with bidirectional data, though I think a couple of folks have attempted it.
