I received the Predator today, and while installing the 65 HP tune it didn't recognize a "Turn Key On" prompt. The install failed. Now, no matter what I try to do, I get "Invalid license. The tune in this vehicle does not match the last tune written"

Of course I live on the West Coast and both Diablosport and Motorhaven have closed for the day.

Any suggestions?

Im not familiar with the Preditor...but aren't you able to update the tuner via the web?

 

Use a battery charger hooked to the primary battery. You must have all electrical accessories turned off. Any voltage change will terminate the program. Then try to restore the original tune. Then try to load the 65 tune.

 

OK, Invalid License

What this is....you screwed up. Read your manual and call Diablo direct. Any power draw when installing a tune will interupt the process. Unhooking your battery will not work because it is not the truck, you need Diablo to reset your tuner.

It is no big deal.... I did this once by mistake, I admit it...

Nothing is wrong, you just need a reset, so call Diablo and they will help. You need to access your truck with a phone so you can plug the programmer in as they talk you through the reset.

I spent some time with Diablosport's Tech Support. Brian was great. He led me through the password and now everything works great.

BTW when this happened it threw a P1000 code. Something about incomplete system rediness test. I have cleared it and it hasn't returned. Would a voltage drop combined with the programming cause that?

Anyway, I love the added horsepower and torque. Thank you to all who replied!

The P1000 is normal anytime the PCM is reset, reprogrammed or the battery disconnected.
