Something is up, looks like massive wheelspin after 5500rpm, it's not a missfire as the afr's are perfect.
Also you'll probably have to add 10% duty to the avcr to get the same boost on the dyno as you do on the road as the dyno won't be replicating the same load conditions.
We mapped your car to about 1.65 bar on the road and backed it off to 1.55 bar as your engine is stock and you drive flat out everywhere![]()
9.2 @ 165mph on low boost
13.6 @ 103mph in a 2.5 ton 4x4
It was me!
will give hyper tec a call on monday see what he says
any more info please lol
I asked Dyno Dynamics to find out what was up as is would seem some of the UK Dyno Dynamics operators don't fully understand how a dyno works or what a power curve should look like
"We have had a look at your graphs and do not believe it is wheelspin but rather the boost coming on hard n the R33 and the dyno then overshooting to compensate for the sudden increase and then the wiggles later in the power curve are the dyno still stabilising. We had to build some smoothing effect into the software but turbo boost developments have meant that we need to make some adjustments to cater for these developments. We are doing a software upgrade so that the operator can chose a mode for normal cars and then one for cars that have significant boost capabilities. "
