Today I go over the past 2 months of work I have been putting into my custom #Mercedes 722.6 TCM for the NAG1 gearbox. Watch to the end to see a surprise I did with my older infotainment system project (You all thought that I'd stopped working on that didn't you!).

I will be working on smoothing the gearshifts even more in my own time, but honestly this gearbox is awful to control compared to something like the 7g transmission by Mercedes!!

One thing I forgot to mention. The reason for selecting 1 pressure from the map to use for BOTH SPC and MPC solenoids is due to trial and error. If SPC pressure is increased compared to MPC, the shift is brutal, if MPC pressure is more than SPC, then the car simply won't change gears! So for now, they are both the same until I can tweak adaptations so that SPC and MPC can be independently modified ever so slightly from one-another to achieve a smooth shift with different gearbox wear.

As mentioned, here is the link to the beta tester form if you want to apply!
