Sorry but if you turned up with a mapped car he would have no idea what settings to use, if someone were mapping on such a dyno they can trn it down run the car and then map it and turn it up. Which is why dyno dynamics works far better as you know or any operator knows to run a 4x4 car is shoot44 mode. The only variables are the air and intake temps and barometric pressure, which if far out it is obvious and they are print on the dyno dynamics printout and how the car is strapped.
Maha measure the drive train losses but reproduce the at the wheels figures from some strange calc that makes them meaningless. Yes it records the actual losses however if the brakes are binding the tiniest amount it is recorded and massively skews the results.
The dyno dynamics uses 22% losses iirc and although one could argue this is less accurate it is consistent and the variance between operators less.
They often read higher than dyno dynamics as does power engineerings old rollers which is now owned by ecutek and has a temp controlled sound proofed cell for development work now.
It would be interesting to compare data from there but the fact there is no standard settings worries me. Maybe a cheap way to gain power though. Worzel best be ready to order more numbers for the back of the car
