Aaron, to clarify a little on what the Impul ECU is allowing.
First, set the Informeter to recognise 100% throttle is 4.12V
Now, When I do a launch from a standing start I get around 45% throttle till about 10kph and then I get 100% throttle.
On a stall launch, I get around 45% throttle. (But this was not done properly as too much traffic around).
But I love this solution... looking for wire cutters on the weekend.
