Hmmm. I'm pretty sure I did it wrong. I have 42.5HP I know the stock M42 is weak but dang. LolLeave a comment:

Yep, always look at the scale if it does not cross at 5252rpm. Also make sure the torque is not in Nm!Leave a comment:

That confused me as well, in fact I emailed the company with that question. When they explained that the HP scale is different from the TQ scale I felt kinda silly for asking, but most keep the scale the same so it's definitely confusing at first.

I used PerfExpert and found the results very repeatable and consistent. The biggest challenge is finding a very level and flat stretch of road that permits you to accelerate and then coast a sufficient distance to establish the drag coefficient. The smart phone must also be mounted with the back of the unit facing straight ahead, and be properly calibrated. So, although there is amble opportunity for user error, if done correctly will produce very repeatable and reliable output. In my case, I had the WRX to provide a standard, which suggested a good setup. Also, the shape of the curve is near impossible to screw up, so that's worth mentioning too. Very fun to mess with and saved me lots of money and time dealing with Dyno shop.
FYI - I didn't find your response offensive, just really excited about this Ap and encourage people to give it a try. I would also really like to see some results from other builds on this thread, only ten bucks guys!!

It seems like a cool app, but what I don't understand is that HP is a calculation based on RPM and TQ. Specifically,
HP = RPM * TQ / 5252
So, at 5252 RPM, HP and TQ are equal always.
I'm still interested to see how it looks compared to a real dyno graph!Leave a comment:
