Default Gtimer2 Power/Torque Maps

Has anyone in the US produced power/torque maps from a GTimer2 unit on a stock 350Z?

There is some debate to the actual power output of the Euro specification 350Z. It is quoted by Nissan as 280PS (276hp), but most Japanese performance cars are also quoted at this figure (NSX, Skyline, 3000GTO) due to a gentlemens agreement.
It would be difficult to get decent dyno reference from UK & US cars, due to differences in workshop kit. The GTimer2 seems to useful as a reference for this purpose.

I have attached a map of an early run in my car (it had only just been run-in), though we would need to sync our setup car data to get more acurate results.

Did you put in a correction factor for drivetrain loss, or is that chart a representation of flywheel HP? Which gear were you in?

I am asking because most of the HP/Torque curves from Dyno's seem to show a much stronger low end and a weaker high end than the one you have.

Your peak numbers look very nice if it was RWHP, but not so good if it was Flywheel HP.

Also, my car weighed 3400lbs with me inside (I weigh 170 lbs).

Someday I'll get one of those devices and let you know what I find.

16% was entered for drivetrain loss and I pulled in second gear.
I thought the low down torque did seem a bit low but I'm unsure on how accurate the device is over the entire rev range (the torque figures where calculated from the hp figure output from the device)
I got it mainly because I plan to mod later and I thought it would be nice to see on paper the results.

Has anyone else downloaded data from this unit.
