Well it appear we might have solved the issue of the Speedo going into fail safe mode in each heat! Changed the sensor wire and the car ran fine in the final. Just a shame it's still so tail end happy - thinking that a 13.5 is just too fast now with the new Speedo, will pull back on the throttle next week.
I know Chris runs a 17.5 motor, maybe a slightly slower motor will still be quick with the Speed Passion Speedo.
So Maz, have you built the new car yet, or will you do that on the plane home, something to keep you busy in the air
