7speed getrag DCT transmission swap.

Meanwhile yeah I thought the shifts were a bit slow and clunky. Calzada is going to help us where he can. Whatever we come up with tech-wise will be handed over to KMiata for possible future kit.

The shifts maybe clunky because his ECU can't reduce the torque proportionally during the shift as the TCU would normally request to the stock BMW ECU. The shift speed may be increased through the software but this will increase the jerky shift even more.

its downright brutal when its full on in "sport" mode..
Video of the same controller in a E30 shows that is doesnt need to bee soft and slow like mine. He runs the same ECU i do.

If you happen to know the answers, I have a few questions.
How fast in milli-seconds can this transmission possibly shift when tuned for it?
Can it shift with no torque reduction at all?
Could it take 500-600 hp and also shift with no torque reduction?
Max RPM this box can handle?

Its a good idea to run either throttle reduce or ign cut(outputs in the controller for both).
People have run 750nm on the stock clutches at lower clutch pressure levels than we do. around 900nm on stock clutches, closer to 1300+ nm on upgraded clutches. The gearsets seem to take pretty much whatever you are able to put into them

A full shift operation takes about 80ms, but a normal throttle reduce/ign cut time would be around 30-40ms. One clutch starts engaging while the other starts releasing so in does not really drop drive to the wheels.

You mentioned it's a good idea to reduce throttle or cut ignition. I'm guessing clutch wear if you don't?
