Dynamometer Test

The last open pit lane session at Knockhill with the Westfield club revealed some performance issues on the straight from Taylors up to Duffus. Every time I changed up the power was taking too long to build up again. I took the car to Sitech to find out what was going on. Simon revealed that in the lower (throttle openings) and high engine revs it was being over fuelled. The theory is that this was throttling the engine when lifting off to change gear. Simon completely remapped the Power Commander such that at all throttle openings and rev ranges the correct fuelling was being delivered. All I need now is a track day coming up soon to try it out. Simon did say tht the power sensor on his Dyno is playing up and could be 10-20% down in absolute numbers. I have pencilled in another session after Croft.
