To my knowledge he's only been there for the tune 'read' and 'write' and not 3 times.Originally Posted by Lucas_R
massive boost spike which is still currenty unrectified - so he will have to go back again at least one more time. You should see the dyno sheet.
The dyno sheet was at an alternative dyno centre we have no idea of their work nor set up so I've asked for the car to go and get it on our trusted Dealer's dyno who actually did the tune for proper logging to check whether it's spiking, and if it is, then we'll tweak it accordingly.
I'm told by the Dealer that client did not want the driveshaft off (2wd dyno), which is why it was then logged in full on a road test and no spike - holding a flat 22-23psi everywhere. The limit on the vRace file is 24-25psi which it'll hit and then immediately settle and bleed off to 18/19psi at red line. This one, we have no idea from the dyno run as it was a power run only so not really ideal.
However because this other dyno centre is showing a clear spike when I saw the dyno sheet I said he would have to get it in to have it properly looked at by our dealer - not some random.
If that would have happened in the first place again, this would have been avoided, but client wasn't necessarily to know that.
Really the curves should look like this on his R
Whereas his hits at 3k as here, but then immediately drops on the torque curve significantly before raising back as normal. We suspect the dyno, but need it on our Dealer's dyno for investigation before it can be checked properly and then dealt with/tweaked accordingly as required.
