Nope can't do it with mine :( I can't even datalog at the minute as the software has changed on the hondata website and doesn't work with my ECU map.

I'll put the back seats down next time, that give 10bhp apparently
:wink:

James did your civic hit full boost? I only ask as some of the other cars seems to hit higher boost on the road compared to the dyno. I

I think the boost thing doesn't matter as it runs off a belt rather than exhaust gas. I think it's more to do with the fact that 3rd was used rather than anything else.

both mine and christians car runs the same boost on the dyno as it does on the road.

remember this is measuring boost on a controlled acceleration rate and we are building boost with a open throttle.

if we held car at a higher rpm and then quickly open throttle it may well see the spike so many of you are talking about

The AVCR logs boost in Kg /cm2.

1 Kg/cm2 = 0.98066494Bar.

My made slightly less boost on the dyno than it does on the road, but only very slightly.
I cant imagine how running in a different gear can affect the power of the engine. An engine produses the same amount of power no matter what gear you are in i would have thought.
