Diablosport Predator tuning issues.. No Cruise control, and Cant Change tire sizes.

My jeep is having a lot of issues. Gonna start with the Diablosport predator tuning. I Plugged it in, and found my jeep had to be updated (This is 1 week after i brought the jeep to the dealer for transmission issues and they diagnosed it, and told me everything was updated as far as computer goes).

So I updated it, and then tuned the jeep using the 93 octane tune. However I only had 89 Ocatane in it so i put a bottle of seafoam claeaner stuff in the gas along with a bottle of 104 octane booster. And I made a 200 mile trip, and the cruise seemed to be intermidently working, the I thought I figured it was becuase it wouldnt let me set it at 80 mph. Cuase when i went slower it worked. I thought this could have been some sort of safety issue that changed during the update. But now its not working at all.??

Next issue. The second issue, is my speedometer is about 5 mph off due to bigger tires. So i tried to change the size in the tuner and it kept coming back at me saying not available. Am i missing something?

Thanks for any help!!

Re: Diablosport Predator tuning issues.. No Cruise control, and Cant Change tire size

do some searching...I know there were A LOT of issues with the 05's and the Predator...make sure you have the most up-to-date predator software (I know you said you updated, but after searching check to make sure they are the same). I def remember others having problems lemme see if I can find a post


Edit - here is a thread with some good info, hope that helps
