So, we've established that GreenMarine's results, comparing a learned stock ECU with an virgin stage1, show that the stage1 offers a slight improvement.
Does anybody have any idea how much effect the learning could have? Are we talking 1-2hp or 10-20?
The power mode will not make a difference to the ECU learning, but the california mode might.
