Diablosport Forums

I have an early buld 300c it would not let me update or change firmness orf shifts nor shift points the controller told me the TCM needed an update. Well i had the dealer do the update on all of my systems today, got the car home and reinstalles the 93 octane cann tune and the car would not start! I reinstalled the backup original and the car would not start! I unplugged the batter pulled fuse 11 i did everything that i could possibly think of as well as asked the guys on 300forumz! Nothing! I have had to have the car towed back to the dealer, makes me sick! Is the predetor not good to use on the very early builds? my bulid was in 3/04

Please help or let me know how i can get my money back!

What year is your 300? what model programmer did you use. Reason being is because 05' is the earliest year you can use the programmer for the chrysler. If you are using one designed for a 05-08 then yea you have done some damage to your car.

Car is obviously an 05. There were no 04s.

Did you reinstall the stock tune before you had the dealer update? If you had them write over the Diablosport tune you messed up the programming between the tuner and the car.

my build is 03/04 and yes i reinstalled the stock tune before going to dealer

ouch
Keep us posted

My 2005 300C had a build even earlier than yours (02/04) and I had to get the TCM update. I didn't go through a dealer on this, I got an updated TCM from Mr. Incredible. Once I got the update, everything worked fine with the Predator for me. Hope you get this figured out.

Who is mr incredible and how do i get ahold of him?
