I would have thought Pure would have come out with something by now considering a fully built one is $20k smh
They are not 20k lol...
I spoke with HP Tuners in early 2021 about this. The Dodge system is not like most valve bodies in which you hold first and reverse. Dodge holds first and second gear together. This is purely in the firmware/pcm. HP Tuners has no plans to port this to any other cars due to chipset issues. Here is what it boils down to.
2015 Cars -> Island onto themselves, chipset is different and doesn't have space to hold extra programming of 2018 PCM, Chuck a 2018 PCM into a 2015 and you'll have a bad time.
2016 - 2017 Cars -> Island to Island, chipset is different and doesn't have space to hold extra programming of 2018 PCM, 2018 PCM might work okay on these cars?
2018+ Cars, might be able to get away with loading a Demon Cal but the BCM would have to be configured.
HP Tuners doesn't not want to spend the money/time/research on making a solution that will work. I heard Sipple was testing but I don't know what they would be testing, the valve body is electronically controlled so unless they trick it into 1+2 and locking up I don't know what would do it unless they have a manual valve body. However that would suck shit going through 8 gears so...
Just buy a TH400 and be done with it.
