Late-model RAM trucks lock their factory PCM against aftermarket reprogramming, which is why HP Tuners ships the PCM-0R-16RAM as a pre-modified replacement rather than a stock unit. Built for 2016-2019 RAM 1500 trucks with the 5.7L Hemi V8 (2019 DS body style only), it restores full write access so tuners can calibrate through VCM Editor without fighting the factory write-protection.

HP Tuners PCM-0R-16RAM Compatibility Notes:

• Covers 2016-2019 RAM 1500 trucks with the 5.7L Hemi V8, limited to the DS body style for the 2019 model year.
• Requires PROM installation or a computer flash to configure the unit for the specific vehicle before use.
• Pairs with VCM Editor software for unrestricted calibration access once installed.
