Mine goes away when I swap the stock ECU back in. So don't think it's related to the valve in any way.

Thank you!

After swapping my factory ECU for the Diablosport supplied unit I constantly throw a P0405 code. If I clear the code, it immediately returns. Purchased the ECU/tuner through Hemifever and after contacting him this was the response.

Diablo has found that there are 2 hardware types for the '15 6.4 ...

Thanks, but if it is stored somewhere in the ECU could the dealer easily retrieve this data and realize it was not in sync with the actual mileage?

This can be fixed by a dealer that's willing to do it. Search on the ramforum.com site and you'll get several hits regarding the exact procedure. My dealer did it free of charge and it worked perfectly.

When I ordered the ECU/tuner, was asked for the vehicle mileage. Can someone please confirm either way if the mileage is in fact recorded/stored in the ECU? If so, how is it accessed since it will obviously be inconsistent with the actual vehicle mileage over time. Thanks.

Appears to have been released on Friday:) Just ordered the kit (ECU/Programmer/Tuning) from Hemifever. Hope it's worth the wait!

Any updates on a release date?

Not sure we are all operating off the same Gregorian calendar here:D

So...any announcements at SEMA regarding support for the 2015-16 Ram 6.4's? Or are we still at the back of the line?

Do you have a date i2 support on 2015 Dodge Ram 2500's with the 6.4?
