PC V wrong shift pattern

So my dealer installed my AR exhaust and PC V. Well, I went to have my bike dyno'ed today and the dyno is reading the wrong shift pattern. In neutral the dyno reads 6th gear and as they moved through the gears it read 5th, 4th, etc.

Did my dealer mess up the installation of the PC V? Will this require them to go under the tank to get it right?

Installing the PCV shouldn't mess w/your gear position sensor. You're talking about the one on the dash? If you're talking about the actual Dyno... how does it know what gear you're in (or for that matter, care?)?

Did you have your dealer set up your PCV so that it would pull data from your speed sensor in order to have a custom map for each gear?

Ah. I should have been more clear...it was the gear indicator on the dyno. The bike appears 100% fine, but the guys at the shop thought something was amiss with the PC V installation to make it (the dyno) do that.

The shop does a lot of dyno stuff but I was the first S1000RR...maybe they didn't have something set up right.

I wouldn't worry about it... sounds like they had something weird going on w/their dyno. You're just running a single map, correct? Not a different map for each gear?

Usually they're just hooking to a plug wire for RPMs and then they hook a USB to your PCV and then they have the exhaust sniffer.

Is everything working OK?

Everything appears outstanding...and yes, just one map. I wasn't there just for a dyno run, I was there to get a custom map created. The before and after was pretty amazing. The curve is much, much smoother and the bike is running great. I gave her a bit of the business on the way home and she behaved quite nicely.

BTW, thanks to your DYI, I grabbed some rubber stoppers to block the PAIR valve and got that bit done before I took it in. Wouldn't have known exactly how to do with it without your post so kudos to you my friend!

No sweat... sounds like you're sorted out then. Post up your dyno printout if they gave you one. What mods do you have? Did they do a before run prior to any mods?

Dynojet have sent the units calibrated incorrectly.
We have made them aware of this and future units will be calibrated correctly.

Simple fix if you need to fix it for individual gear mapping.

Re calibrate it using the tools at the top of the Pcv page. Only possible on a dyno.
