Question, new ECM installed

[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

Yes i read the ecm tune before starting the car, it is exactly the same as factory ECM 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

 

[Unholy707]

My color connectors don’t match the colors on the pcm the grey and the tan are swapped lol. But they will only let you put them in one way. One time in a rush I tried forcing it and broke 1 side of the slider - there’s little plastic nubs in the pcm that will prevent you from putting them in the wrong way. I would contact hp tuners asap, could be something wrong with your pcm

Yes I did it
Don't know what to do
Will contact HP tuners, but what they can do, they unlocked ecm,

 

[Unholy707]

But try writing your tune back to it first I suppose, see if that fixes it. It’s just a calibration file

 

[Unholy707]

they could have messed it up when they unlocked it. They change blocks of the code. They also have to open it up on a bench

 

[Unholy707]

@fumanchu182 also does unlocks, not sure if he can do something for you

Yes
I created a ticket with hp tuners
But i think what they can do?
I think i will try to find a tuner near my house, can not drive the car with engine light blinking

I created a ticket with hp tuners, will see....

Mm
Interesting idea
The file on unlocked ECM are the exact match with my original file that I saved
What do you mean calibration file?
Also waiting for my tuner to send me my new file
But I wanted to see if ECM after unlocking will work

Could be
But how to check it
