Guys I experienced first hand the two stage issue?stutter. What was happening with my car was this. Turned on, the speedo was i neutral. Three pulls of the trigger from 0 -100 then the green light flashed one flash consistent. I tried a reprogram, I tried a manual reset, and I tried to call Albert... I thought my speedo was bad due to the fact of the motor was brand new, so I wired the second 2.0 pro, and reset the basic setting, and rechecked. The green light still flashed. I replaced the sensor cable, and it still flashed. Then I said, I will swap motors. Did so and voila, flashing light gone. I opened the motor and replaced the sensor board, and rechecked everything, reinstalled the original speedo, and sensor cable. I had the opportunity to do some testing today. Let me just say, my car has never been faster. People asked all day, what motor is that. I replied "Its a Speed Passion 13.5 MMM", they replied "13.5???????????????...
I added 1 OZ, just to keep the nose down.

I cant wait for the Reventon's. My SP 4400 KV/paired with a 2.0 pro in blinky mode rocked today. I let e few other guys rock it for a little, and they could not believe the difference from their own cars.
