Here's the steps I've taken..
Connect the Predator to 12V power supply
Connect the serial to USB then click on the Diablosport Downloader
Went to express tune mode and selected COM3 and 57600 baud rate
Went to options on the Tuner and clicked on Custom Tune then import.
Then clicked "Send Tune file to tool" then selected your tune that was downloaded to "My Documents"
Next it will say"The file download was aborted due to a transmit failure"??
The tuner screen says the same thing "unable to import file, the format wasn't recognized"?
When I connect the Tuner with the USB my laptop screen Doesn't say "Hardware detected etc.. like when you attach a digital camera, could this be the problem? I need help please...Craig

99 SVT Cobra U7146 Tuner revison v.9R05

Problem Solved I used a different USB Port on my laptop and clicked on the Auto connect tab and it was able to detech the predator, I successfully imported the tune. It did do it as a 115200 Rate, is that OK? That's what the U7146 asked for... Just curious when I clicked on the "Modify Custom Tune" the Spark Advance and Fuel adjustments where set where I had them on the canned 93 Octane Tune, 6% Spark Advance and 3% Fuel richment, shoud I reset those parameters to zero and reload the Custom tune? I'll be calling my Tuner about it but he isn't available til tues? I would assume he wouldn't want any additional tweaking of his tune til I send him my Dyno Sheet and Datalogs?

Well, since he is the on who created your custom tunes, I would wait to speak to him about it.
