There is a significant difference in tire diameter between the front and rear but use the rear tire, it is for speed calculation and rpm is in direct connection with the rear wheel
Thanks ,ive double checked my settings and gear ratios,but getting over 400bph showing on stg 1, not sure what i'm doing wrong, ive emailed my settings etc

Loving the concept and idea of the app and I want to be able to use it but I’m struggling with the finer details! I’m DCT and just struggling with the spec of the car and ratios etc here is a log anyway

it’s an old log as she is now off the road waiting for turbos and new engine to go in!

I do realise it’s an old thread too!

R u from Australia or some place other than the US? Cuz I see ur graph is using STD correction instead of the typical SAE.. btw, ur smoothing is set to 1 instead of 5, was this to inflate ur nbrs as much as possible or?? Lol
It appears to be a manual car, a common user error from MT measurements is while datalogging, the driver presses the clutch in sooner, than he releases the throttle, that causes an rpm spike, and spikes the torque reading, which throws off peak numbers and invalidates a measurement.
