I'm just using the Avcr as a digital boost gauge and have noticed something a little weird. It seems to display more boost than is actually there. Here's the situation: Running hondata S200/w Boost with a gm3bar map. Tial 40mm wg with a 8.7psi spring.Boost cut is set at 10psi. During a run, the avcr will peak hold a .78 bar reading and the hondata will datalog a 6-6.3psi. .78 bar equates to about 11-11.4 psi. ???????????. I am trusting the hondata along with the greedy boost gauge seeing as I never hit the boost cut. Anyone else out there ever noticed this????

And by the way, the manifold is taped for all vacume source. Each seperate componet has its own source. I can switch them all around and get the exact same readings.

 

Mine did the same thing, and I don't think that its at all uncommon.
