For WHP it says to use 0% drivetrain loss.
I use mine in an iPhone holder standing straight up. It has been pretty accurate in the past for my bone stock 240sx (said 130whp) and my friends 2000 Prelude SH (176whp)

If it I have to run a "1/4 mile" every time, then it is useless. First, I don't have any place that long and flat that isn't an actual 1/4 mile track, and second I'm not trying to go 125+ on Rt1.
How would you be able to accurately measure it if you dont do it from a standstill? Your jerking all around when moving and it only uses the accelerometer to measure the power. So any slight movements and it will throw it off
