vr6 rolling road - remaped?

Recommended Posts

had my vr6 on a local rolling road today, didnt look particularly technical the piece of kit they used but they came up with the followng results... dont really understand them too much and i wil scan in the graph tomorrow, but with original (as far as i know!!) ecu, and no enine mods other than k&n and a magnex cat back exhaust (130k miles on the clock too), do these results look ok, is it easy to tell if it has been remapped or had another chip fitted? I am looking at having the top end rebuilt clutch tappets timing chain etc

cheers

Hmm those numbers are just odd.

 

212 bhp at the flywheel equates to 193 bhp at the wheels? That's an incredibly low transmission loss and a rather high power at the wheels too.

 

And 234 what in torque? I assume that's in Nm? If it's lbft that's a spectacular figure for a "standard" VR6. If it's Nm it's a shade low, only about 170 lbft.

 

The shape of the torque curve is odd aswell. Massive peak at 3600 and nothing over 4500? Doesn't look right to me.
