RSTuner Performance Analyser

[richy22]

Did one this morning first time I've tried it...god knows if its correct??!!

In comparison to the RR day I did recently I had 141nm of Torque and 162.6bhp

This is showing 189.99nm of torque and 113.46kw which equates to about 152.15 bhp.

No-one else done one to see if im doing it right?

You have to keep in mind that a rolling road session is normally done indoors. And a live read done using the RSTuner is done outside. The road surface, wind and the humidity can all affect the outcome of the final result.

For a more accurate reading, you need next to no wind, a perfectly flat preferably half a mile stretch of road, which is as straight as possible.

There is not chance that the two readings you have are going to be close to one another. You have to take into consideration aerodynamic drag. Which when using the RSTuner calculates drag in KW. Which I would imagine is what you loose when comparing a RSTuner run to a Rolling Road run.

Maybe add the drag KW result to the power KW result and the outcome will be more true!?

Thanks

I just wanted to know if I was doing it correctly I.e weight etc?

Well, weight for a Clio 182 is 1090kg, and then you multiply 0.737kg for every litre of fuel you have in your tank, and then add yourself. Then for other liquids like engine oil, break fluid and screen wash, I’d add 25kg max.

This is a good start and probably an accurate of a guess anyone could make. Or if you know of one, go to your local weigh bridge. Mine cost me £10 ago, and that’ll be spot on.

And how much it weighted?

And how much it weighted?

At the time 1384.74kg,

Full tank of fuel and my baby chair in the back.

And my girlfriend in the front
