110 - the car had good acceleration on 4.5:1 but was at top speed in a matter of metres. If I geared the car up it would start to bog down. The motor was only running at 35 degrees!! I would say this software would only be good for a tiny track.

107 - basically the same result as 110 but with a fraction more power.

731 - I tested this software because Cyande had good results on big tracks. In my opinion it was much quicker in a straight line than the other two software options and hit top speed much later. The motor only came off at 45 degrees after a 5 min run. My only gripe is that it is very slow off the line ( I think the programming needs a rethink on start up). I tried reducing the timming on the speedo just in case it had too much and this did not fix the problem but did reduce the cars top speed.

I think if speed passion used 731 as a base line with better start up software it would probably be quit fast. I would probably add more timing at a higher RPM too as it could still go faster and considering how cool the motor is, should be fine.
