I downloaded my winter tune to the Predator, installed it in the truck and the truck wouldn't start.
I tried to restore the original tune but the Predator will no longer read my vehicle.
Now, truck won't start, Predator won't work, it's Sunday and no one is open.
A little help would be cool.

 

is the theft light flashing? You may have lost the pats programming.

Did you save a copy of your original program that you sent to the tuner to modify? Maybe you could download that stock program back to the predator and see if the truck will take it.

Otherwise, you will need to ask one of the tuners for advice. Mark at LFP has replied to my e-mails on Sundays.

Hope you get it figured out.

 

Try to put any tune you have back on your truck...stock, winter, whatever.

What does the predator do when you plug it into you truck?
