"As of right now we are using http://soundgermanautomotive.com/pcs/ . His kit comes with a harness and uses a CAN playback box to fake out the factory TCM, making it think it's in a new production vehicles. It also requires a new 8 speed factory shifter. Also we had to purchase hp tuners and 4 credits to unlock the trans and adjust a torque converter setting. Since torque management is disabled on the Mopar crate ecm kit, the trans can drop to neutral when coming to stops because engine rpm may get to low.(currently only in track mode because of the aggressive shift schedule, other modes work fine) We are using a brand new under warranty hemi crate engine and didn't want to touch the ecm in case warranty was needed. A setting in HP Tuners helped with dropping to neutral except in track mode when coming to a stop. With out torque management for the ecm from the tcm to quickly adjust ignition timing to maintain a low precise engine rpm, it gets dragged down to low and trans drops to neutral.(flashing D on shifter) After the engines warranty is up we plan on setting min idle speed up some with hp tuners which should take care of that issue. Since we were very early adopters of this, there was some other bugs that got worked out and SoundGerman worked on software updates in a timely manner. Depending what ECM (factory/crate) / TCM combo could affect what software sound german sends. Our situation may have been a little unique because it doesn't seem like he got many people before us with the actually brand new factory crate. We got the trans used, the crate kit was never meant to be connected to an auto trans. Which is why Mopar disabled torque management. The crate ECM is apparently unlocked so cost is minimal to use hp turners on it. There is another company out there selling a kit that enables torque management but requires flashing the ECM. I don't have any experiences with their kit to know if it is bug less or not. The Soundgerman is working fine for our application. As time goes on if the any kits appear to be flawless maybe we would consider them if cost is not insane. flashing software and swapping a harness is very little labor. But I don't for see that with how this kit works today. Also the 2018 center console looks factory in the 1974 Cuda."
