Ok, thanks I wasnt sure as the one we use got an older software version ! By the way I got a question about that Have you notified lower power results on dynodynamic than other dyno like dynojet ?

The powers not lower.. Its correct.. DynoJets Read about 15% higher and are inacurate.

On my dyno, I have had cars that I thought should read lower, and I have had cars that I thought should read higher. Its a mixed bag really... Could be partly to the effect that I use roller speed to calculate RPM as I always get frustrated trying to pick up a tacho signal from a Honda and partially to do with the ramp rate used when making pulls. They did upgrade my firmware recently and as lucky as I am, my car is down from its normal 289-291 whp to 267...so about 20+ hp from a firmware change. Oh well...
