Cel dod delete

[Buddy B]

I'm thinking about doing a dod delete on my 18 Silverado. Somebody told me if I have this done there's a chance I may get a check engine light thus making it difficult to pass NJ inspection. Can this happen?

Are you talking about physically removing all the parts or just wanting to install a AFM/DoD device that turns it off.

 

One is many thousands of dollars to do and the other only costs like $150. If you removed all the parts, it would have to be re-tuned by a shop and they would have to turn off all the error codes that come with that. The cheaper plug in device should never cause a check engine light.

Yep, as Cam said, full mechanical DOD delete you need it tuned.  

 

If you are talking leaving the mechanicals alone and just turning off DOD, a shop can do it tune style where they go in and just turn off DOD, or you can use an OBD device like a Range.  The only problem with the Range is, if NJ does an OBD emissions inspection, you will need to drive around for a week with the Range removed so the truck can run the readiness monitors, otherwise you won't pass.  The tune the ECM method would make it so that didn't happen.

A tune would make all the check engine lights go off.

 

You can't even start the truck after the DOD delete without a tune.

Thanks for the info
