This.
By actual, I mean effective. Since we have significant sidewalls, 225/60R16, the deformation makes the effective radius of the tire around 25.71-25.84 (GT lists first size, GTP lists second)
Also curious as to why there is no compensation for torque converter slip.
In that red curved I removed the last data point and it jumped back to the next high of ~330 HP. Still nowhere near accurate because of spikes.
The light green pull is the most believable curve however, does it consider air drag? Third gear covers ~84-125 mph. Significant increase in rolling resistance up there. If anything though, it seems to think there is more drag than what was seen by the vehicle.
Based on how sensitive this program is to bad data, I'm not sure it is worth using with our logs as they all seem to be error ridden.
