AutoProm / TunerPro RT Data Logging Issue. Please Help!

[BWilcox]

Hi Guys,

Have a data logging issue for the data communication experts.

Using an old AutoProm / TunerPro RT combination and the GM 7730 ($8D).

TunerPro RT connects just fine with the ECM on and the engine off. After the engine is started, TunerPro locks up.

Help?

Could the ignition noise cause the issue?

If so, is the interference likely to be EMI or running down the ALDL or USB 2.0 cables?

Best Regards,

Bruce
