Message: [QUOTE="Jeremy, post: 1336569, member: 848"] Ok so I've been working with BD's engineering department on my particular issues, and they have been great to work with. I'm 95% happy with how it works now, just a few little bugs to work out. I can say that the engine brake is very effective and it is stronger than the factory option on the 15-16 6.7 PSD. I hooked up the exhaust brake function to my up-fitter switch so I can turn it off if I want to. I wanted the ability to manually select a gear and have it stay there with a locked up torque converter and it does that now. At first it did not like my SCT X3 program when I used the TS in automatic mode 1(basically mode 1 lets you select the highest gear the truck can shift to, so if I pick 4th it will shift up from 1st, shift up gear by gear and stop at 4th it won’t shift to 5th etc) The issue was the SCT was set up for TC lockup in 1,2,3, and TCM was expecting to see that. The TS was not set up to do TC lockup in 1,2,3 in that mode, so I would get a flashing tow/haul light, because the TCM did not get the results it wanted from the trans. BD emailed me an updated file to fix that issue, and with a micro USB cable it was fixed in 30 seconds. BD made it very easy to update the TS. The Edge CTS will not display the TC lockup on its screen, because the factory TCM isn't controlling that anymore when the TS(Tap Shifter) is on. The kit comes with a LED for the 03's so you can see that you have engaged "tow/haul", I used that LED so it lights up when the TS is commanding torque converter lockup. It a nice feature to watch the TC lockup on the CTS and I missed it when the TS is on. So it does not affect your custom tunes, until you turn it on(press the "-" button). Once its on the TS shift schedule takes over. This is why I like the manual mode #7, I can turn it on to hold a gear towing up a grade, and adjust which gear I want it to be in on the way down with the exhaust brake on or off. When I get to the bottom, I just press the "+" until the BD display gets past 5 and it turns off, and I'm back on SCT trans tuning. Its not for everyone and it does not work exactly like a new 6.7 does but its close. I hope this helps. [/QUOTE]
