[Al Lo]

Hello everybody
Hellcat 2020
I sent my original ECM to the HP tuners for unlocking
After unlocking i reinstall everything
now rough idle, check engine light is blinking, codes 0053 and 0803, and exost smells vierd
No codes or problems before ecm service, battery fully charged, checked battery connections
Please help with advance 🙏 😊

Have you called HP Tuners?

 

[Al Lo]

No I did not
Only email is available
I will try, but I think HP tuners will not be able to help, they unlocked ecm what else they can do

Did you pull your stock tune first and email it to them before you mailed it out? That’s what you’re supposed to do

 

[Unholy707]

If you have your stock tune file still (hopefully you do) reload it. But I’d take a read first and do a compare to see if they loaded your stock tune file

tune

Thank you for your reply
I think with original ECM unlock service I don't have to email the tune
However, I read the ECM before starting the car, it is the same as factory original tune

You didn’t force the plugs into the wrong spot did you? Are they full seated?

 

[Unholy707]

They should have went in the pcm smoothly and connected smoothly and drew the connector onto the ocm when you flip the handle on the connector

Yes they are fully seated, i didn't force it during installation
Its 2 colors i matched it
