Solved

Changed:
I have same problem with both ECU. Followed the instructions from help menu step by step when it calibrated.

TPS1-2,PPS1-2 inputs calibrated

TPS% without ETC controller is on 5%

At first time when i connected the ETC motor to the bridge(ETC DC was 0%) the TPS went up to 100%. I Tried on ETC DC=100% the TPS=0% . Ok i tought i have to swap the ETC motor pins. I did it but when i raise the ETC DC From 0% to 100% The TB is closing not opening.

My measurements:

The NFET driving bridge output EC10/pin2 was damaged => unable to pull to GND (so output was +12V all the time).

* the NFET also had some (not very strong) coloring due to heat

* since all outputs are tested before delivery (the NFET was originally good, driving the load and the "blue" indicator LED in the tester)

* the only likely cause is accidental short to +12V during install (possibly without a fuse, or high current fuse)

** the FETdriver, traces, and other components seem to not have been damaged at all

Symptoms were (with both ECU):

* Followed the instructions from help menu step by step when it calibrated.

** TPS1-2,PPS1-2 inputs calibrated

** TPS% without ETC controller is on 5%

At first time when connected the ETC motor to the bridge(ETC DC was 0%) the TPS went up to 100%.

** I Tried on ETC DC=100% the TPS=0%

** thought I have to swap the ETC motor pins. I did it but when i raise the ETC DC From 0% to 100% The TB is closing not opening.

Measurements:

Changed:
ETC DC=0% (in Econoseal10 connector)Between Pin1 and GND = 0V, BTw Pin1 and Pin2= -12.14V, Btw Pin2 to GND=12.15V

ETC DC=100% Btw Pin1 to GND = 12.19V, Btw Pin1 to pin2=0.11V, Btw Pin2 to GND = 12.08V

Maybe a wrong FET inside the Bridge because the Pin 2 voltage doesn't change?

* ETC DC=0% (in Econoseal10 connector)Between Pin1 and GND = 0V, BTw Pin1 and Pin2= -12.14V,

** Pin2 to GND=12.15V

* ETC DC=100% Btw Pin1 to GND = 12.19V, Btw Pin1 to pin2=0.11V, ** Pin2 to GND = 12.08V

Replacing the NFET solved it, pin2 reacted as it should.

Note: preferrably use the backout plate in the econoseal connectors (normally yellow in the EC10) to prevent sliding out of receptacles.
