The data I am capturing from yesterday's initial run with V2 installed shows a maximum of 15.0psi.

In the three comparisons I made when I was able to induce a spike and had the logging hooked up, the TMAP only showed 15.4 PSI spike in the PROcede. However, other than this discrepancy, they always read spot on. So no, the PROcede did not see this spike.

Now why wouldn't it see it could be for multiple reasons. First is that the boost gauges source is in the intake manifold whereas the PROcede uses the TMAP which is in the intake tract prior to the throttle body. There could be a reversion issue in the intake manifold which is only momentarily seen in the manifold.

Or, it could be the range on the TMAP won't allow it see any higher. But I seem to recall something about this being a 1.5 Bar Gage sensor. So it should be good up to about 21.5 - 22.0 PSI. This needs to be confirmed though and I guess I could test this if no one knows the answer.

Lasstly, and not likely, the PROcede is not quick enough with it's A/D to see the spike. Doubtfull though...
