Gear Ratio Problems

Post by indy0651 »

2008 charger RT...I have tried to tune my gear ratio multiple times now. The unit says "gear ratio changed" but when I test drive the car, it goes into limp mode once it hits 3rd gear. when I get home and check the DTCs it says gear 3 incorrect gear ratio. This is a bit frustrating since I mainly bought the unit to change the gear ratio after I swapped to a Getrag 3.06 rear end. Any ideas?

when you go into the gear param now does it have 3.06 highlighted? *3.06*

Are you 100% sure they are 3.06?

I will check that when I get back home. The diff came off of a stock car and has the factory 3.06 sticker on it.

I just checked again and since I paid more attention this time I noticed that the options go from 2.82 to 3.07 for some reason.

Regardless, I tried to program the gear ratio change again and it isn't locking anything in. after the tune, I go back into the gear ratio and nothing is highlighted.

I submitted a tech support ticket last night. I do not have the serial number on me right now, but according to ignition it is up to date.

i checked for updates again and it had 5. Is it normal to have updates available so often? it seems i have updated 3 or 4 times and I have only had the device for a few weeks.
