incorrect, bizarre data in datastream

Post by schwad »


I'm seeing incorrect data in my datastream. E.g. the displayed speed is bouncing around between some 20mph and 250mph, while my car is stopped. Happens both with engine off (key on) and with engine on. Other data (e.g. RPM) is crazy too. Log file (.xdl) can be provided upon request.

Some configuration details:
1992 Oldsmobile 88 Royale LS
L27 engine, H body

TunerPro RT version 5.00.9130

Using definition files:

I did succeed in getting set up properly and reading the datastream years ago, but I've reinstalled my OS since then and thereby lost the TunerPro configuration. Any help is appreciated. Thanks,
