2021 Mustang GT Premium cannot read

2021 Mustang GT Premium cannot read

unknown controller detected on latest beta and firmware on mpiv2

Attachment 108246

I saw an ad from hptuners saying 2021 mach 1 support. Mach 1 is supported but not regular GT?

I think you pick the controller from the dropdown menu, check this post and see if it applies:

okay but what controller is it? i know it's tricore but there are multiple versions

I looked and I can't find what controller it is.... Maybe someone else can chime in and help with which one to pick...

Sorry

well I hope THERE NOT LOCKED

I worked with support to get my definition added so there's a new VCM beta version now. Also I've asked them to add some tables that are not mapped that I use on cobb ford applications.

upload???

Just got a 2021 Mustang GT 6MT in today. Guy just completed break in mileage. No ECU identified so selected the latest TC-298B I believe. Went through the setup process but then was unable to initialize and read. Any updates on this. Running the very latest beta updated today. Also tried the non-beta version just in case.

2020 GT 6MT here works with: TC-298, 2018+Ford

Any update on this? Currently trying to read a 2021 GT

Sure would be nice to know this information considering I sold a tune based on the "supported vehicles list" and now am stuck. Have tried all the available processors in the drop down.

latest beta version and firmware update was the fix.

I just bought a 2021 Mustang GT premium and I am getting the same unknown controller error when I try to read the PCM. I tried multiple times, I also tried selecting TC-298, 2018+Ford which it did read but when I went to save the file I got an error that the file was bad and to contact hp tuners support. Does anyone know how to resolve this issue? Am I missing a step or something? Any help would be much appreciated. I have the latest version of the VCM software.

Select TC-298 manually
