Hello All

Brand new user, so far very happy with the ECU Black  
I have a minor issue. have tried to search. but nothing found.

PaddleShift will not activate due to unknown gear..  
but car is standing still, and gear is calculated = no gearinformation before rooling..  
and hard to rool when not allowed to engange gear..  
there are NO clutch switch.. and engine is an MC engine 1-n-2-3-4-5-6  
my valves engane gears using test outputs.. and i see the upshift/downshift inputs engage..

how to make it activate when in unknown gearstate ?
