Manfred Jahn Basler BT-67 - ASI Problem

Today I am flying around with the BT-67 (V2), but i noticed that the ASI does not match the speeds given in the manual.
VNO should be 180 (on the ASI it is above the redline) and VNE is 228 (which is not even on the ASI).

I found this Video (V1 i think) there you can see an ASI that matches the manual.

Here is picture with the old(?)/other ASI
http://www.avsim.com/topic/378810-basler-bt-67-turbo-conversion-dc-3-released/

Why this one is not in the V2-Version? Maybee can anyone help out with the old gauges/panel.cfg file or know which ASI is used in the vid/pic.

I believe the revised V2 ASI gauge puts the red line at 170, which the panel placard lists as VMO. Since we gained access to one of the real a/c for V2 it is likely that we reproduced what we saw there.
 
Here you go ... you'll find we've done a close approximation.

Ah, thanks for the explanation Manfred. I also see the 170 on the plaque in the cockpit now :wiggle: only in the manual is still the 180 for VMO / VNO


Thanks for the beautiful airplanes which you and your team always give us.

If I recall things properly. The FAA says that if you convert an existing piston airframe to turbine power. what was once the top of the green arc on the ASI now becomes the new (lower) red line with no yellow arc. Due to the (usually) increased power available, it's very easy to overspeed the airframe. So having a lower red line means you won't actually break the plane if you inadvertently go a little over the red line.
