VE table pressure/RPM indicator seems to be incorrect

Hello everyone,

I'm using TunerStudio on my Honda Pacific Coast project with a circa 2011 MicroSquirt. I have been having some difficulty understanding what is going on with the software. Specifically, the VE table when the engine is running has a dot that shows where on the table the MicroSquirt currently is. The pressure (Y axis) reading appears to be wrong. I am in Denver at about 6000 feet above sea level and it normally is around 82-85 KPa here. The MAP and baro sensors read correctly on the dashboard. Here's a screen capture:

As you can see in the image, while the MAP and Baro are reading the current pressure correctly, the little dot in the VE table is in the wrong place!

Is this normal behavior? Thoughts?

Thanks!

Douglas

The engine isn't running, so what happens when it's idling, where's the indicated MAP on the dash, and where's the dot in the VETable.

Weird things happen to the MAP signal when the engine's off. Start the beast up, and it should make a lot more sense.
