I have a problem and try searching but nothing specific comes up. So here is the problem. I have a 2.0 rtek for an s5 na. I was able to link to the ecu using a palm IIIxe but then as soon as I start the car I was not able to datalog because it won't link and would just display an X. This happen ever since. I bought the rtek. I have tried with a pc and it does the same. I have tried it with the palm connected through the craddle and hotsync cable and would still do the same. Just wondering if anyone have this problem before. Thanks. Any help would be appreciated.
