The car is a bmw e30 m50 turbo with Ecumaster and my problem is the TCU dasnt cut the ignition when it change the gears. The aux2 from TCU is connected to analog 5 in Black. the torque reduction is set to 100 in the TCU but i dont have any input signal on Black. i tryed to put on 0 and no change. What can be the problem? Can somebdody to take a look to the attached file?

in tcu 100% means 100% of engine torque. If you want to make a full cut, you set the torque to 0%
you have connected pull up on the analog input in Emu?

The problem was in "Torque Reduction Adapt" box it was sett to 0 now it set to 80.
Now i have spark cut output but now to much time aprox 0.4 sec and i lose to much boost and time.
Which box is responsible for time cut ?
The "Torque Reduction Output" is set to 95 /

At 8hp only torque reduction.
You need to delay the ignition timing.
for the 8HP70 gearbox, the torque when shifting up gears should not exceed 700nm.

do not use spark CUT
