Sorry, I'm not familiar at all with Diesel tuning.
But I have a customer with a Autocal running an aftermarket tune in his truck.
He flashed it back to stock! But the Monitors all show as "Unsupported".

Back Story, he is trying to get the truck to pass smog. He put all the stock parts back onto the truck. Here in CA you have to smog your truck every other year and he doesn't want to deal with the smog nazi's any longer.

Any help would be appreciated.
I did upload the stock file. I did not pull the modded file at all. I just wanted to make sure the Autocal put the ECU back to stock.

I also included a screen snap of the monitors.
