I have a 2013 Dodge Charger R/T and I am trying to install a 91 performance diablo tune. When I click install tune, it installs no problem. When I modify the tune, it gives me the message saying it did not install the tune. Then once I hit more info it says “PCM: Error unlock for reflash (-18)”
I then looked on here and saw something about when the throttle booster is over a certain percentage, that person had the same issue. So I set my throttle to 0%, installed the tune with adjustments to other fields and it installed.
I went back and adjusted my throttle to 5% with traction control disabled, and it didn’t not install. It still sent the same error message.
I tried with throttle at 0% and traction control disabled, same error.
Finally I sett throttle to 0% and traction control enabled. Same error.
If anyone is having or has had this issue feedback would be greatly appreciated. Thanks in advance.

Unless the previous owner tuned it. I’m pretty sure it’s factory tuned.mikel wrote:any chance someone tuned it with HPtuners in the past?

Only mods done are catback exhaust. Unfortunately. I bought it from a dealer that sold used vehicles. So I have no way to contact the previous ownermikel wrote:any previous mods on the vehicle?
