Speedometer recalibration tool for ‘22 ecodiesel

[22ramlaramie]

I was told by a hypertec vendor that there are not any speedometer calibration tools out there for the ‘22 ecodiesel because they have not been able to unlock the ecm yet. Does this sound correct? I also have parking sensors so that seems to be another issue. If anyone out there knows of a recalibration tool out there that will work on my truck please let me know. ‘22 Ram, 1500 Laramie, ecodiesel, 5’7” bed, 4x4, 295/60/20 M/T Baja Boss A/T, Motofab 2” level kit
