I'm using my old Palm M500 with my Rtek and it works just fine except for a couple things, its monochrome/black and white screen making it not a very easy to read unless straight on, day or night. Rtek is a color program. Battery Life is getting shorter which I kinda figured since its rather old being a 2002 or 3 palm. And of course it doesn't always jive with my computer and hot syncing. So, I happen to have a palm tungsten which is way better in all aspects that someone gave me, but its a usb hot sync... like all palm's are these days. Also have a nokia N810 with a palm emulator on it with Rtek installed and running, but it too of course is usb. So, Its getting to the point where I'm needing a new/old palm to replace my m500, that happens to use the same cable to my rtek (options are rather limited so I read on the pocketlogger site) so I can at least have something with more battery life so I can go out for a few hours with the car and still be able to have the palm running on its own battery, and something in color would be nice... or I'll just put my smaller laptop in the car with me and plug it into the rtek and run it from a palm emulator which I've done in the past, or like I do with... the haltec in the 20b 2nd gen I had... can I say haltec in this forum? I mean no disrespect, they just dont make a 20b rtek ecu lol

Further more, I'd love to use my Palm Tungsten E because its newer, has all those features I'm looking for, and it can go days without a charge... but its a usb hotsync. Any ideas on linking the usb to a serial cable for a palm? Its easy to do on my laptops by just plugging a "usb to serial" cable in and making a port connected to the palm emulator, but is it possible with a palm? Or sorta better yet, is there any news on a simple windows program I can just put on a laptop and use with my rtek? I think thats the only drawback I find with my rtek's, I have to sit in the car, with the key on, most times with the engine running, just to make a correction... which can take a while when you're making a new timing map, tuning new injectors based off the wideband VR input, or reading the logs and tuning from there. If I could just have it all and tune with a normal keyboard on a laptop in the comfort of the shop or home like the other standalone's do, and then have the Palm for smaller/larger/whatever corrections on the road, this standalone system would be perfect imo. don't think it would be that hard to port to the windows os would it? Anyways, Great product, have loved it since the first 2.0 and still do with my 2.1s. Keep up the good work.
Thanks

 

USB has two "halves", the host and the peripheral. A host can connect to multiple peripherals, but a peripheral cannot connect to other peripherals. A Palm is a peripheral so it cannot be connected to anything other than a host, which in this case, as in most cases, is a PC. A USB to RS232 adapter is also a peripheral. So you cannot connect it to a Palm.

Unfortunately with the Palm E, they removed the serial port. The E2 does have a serial port, but you need a $50 hotsync cable.
The Zire 71 is a good choice. Hi res, color, rechargeable and hotsync cable is readily available.
