Trinity 2 EX issue trying to tune 2019 Ram 1500 Classic

Post by Stewartd44 »

I'm new to tuning and any helpful information is much appreciated. I just added an unlocked PCM from Diablo and the in-cab Trinity 2 EX with the bypass cable to my 2019 Ram 1500 Classic 5.7 Hemi with an 8-speed transmission. I added the 87 octane along with the transmission tune and tried to disable the MDS, but when I drove the truck, I still got the "eco" indicator on the dash. I tried to reflash the PCM with the 87 tune and tried the diablo tune and I kept seeing the "eco" indicator and each time the MDS selection in the tune was "on" in the parameters. I checked and there were updates for the tuner so I updated it and tried to reflash the tune and turn the MDS off but now it keeps tell me to put the truck in run and touch the screen to continue and never goes past that step until it finally saying "no vehicle control modules detected exiting tuning". If I clear the update it will go past that, but I get a warning that "There are control units in this vehicle that are currently not supported. An update may be required. Connect your device to a PC and run the update agent client to download the update." I have run the update over WIFI and connected to a PC, but I keep coming out with the same issue I described above. I'm stuck and not sure what to do now. My main reason for adding the tuner was to disable MDS, tweak the transmission shifts and any HP or torque gains are a bonus.

eco is not MDS :)

eco just means you arent driving it hard enough, lol. It is telling you that you are driving economically, with a light right foot and ideally getting optimal mileage.
If you set MDS to OFF, then install the tune, its OFF.
