Hello all.

After researching, and not finding a definitive answer, my question remains: Can one write the custom DYNO tune, from the CAR, into the Predator, over the canned tune, from Diablosport, for additional adjustments? I have to make a shift point adjustment, and wanted to see if anyone had success. I e-mailed Diablosport, but, did not get the impression they understood my question, by the answer they sent to me.

Any help would be appreciated.

Thanks - Chuck

 

if you have a tune in the car, you should beable to upload that to the predator as long as it has not been installed on the car previously. im not sure if you can just to make adjustments without effecting the rest of the tune

 

Using their utility and reflashing the Predator itself,
you can make it adjust about the "found tune" as-is
rather than pushing its set of "install performance"
changes.

This is done as the first step in the RWTD custom
tune process, you do not necessarily need to take
it the rest of the way (just change the Predator's
way of adjusting, skip the over-the-email tune bit).
