PCM: Error Unlock for Reflash (-18)

Post by TrevianB »

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.

I tried to tune it with an intune i1000 before I figured out it didn’t support my year but it didn’t write my vehicle

Unless the previous owner tuned it. I’m pretty sure it’s factory tuned.

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 owner
