90 corvette map sensor
Well I was able to finally get some data logging in today just toying around with it to get it to work and was looking at the graph for my map sensor
At 100%TPS it shows 29 inches of vacuum and at cruise it is showing roughly 12 inches. Anyone know if this is normal or needs fixed?
If it helps i can post the log or send it via email
Thanks!

Sounds backwards. You should have low vacuum at WOT and high vacuum while cruising/idle.
Maybe it's displaying PRESSURE rather than vacuum? That seems more likely, given that it's a Manifold Absolute PRESSURE sensor.
