Low manifold pressure indication

[Rob Hickman]

If you set the EFIS Altimeter to zero feet the Baro on the EFIS should match the Manifold pressure.

We have three different manifold sensors that can be selected. Since you are not using our sensor will have to guess what you actually have.

1. Select P/N: 41201 Turbo and press SAVE.
2. Return to the EFIS main run mode and set the Altimeter to zero feet.
3. Read the BARO value on the EFIS screen at zero feet.
4. Return to the Manifold Calibration menu.
5. Use the Shift Adjust setting to make the Manifold read the EFIS Baro value at zero feet.
6. Press Save

I think the problem might be the lasar ignition system. It tees off the manifold pressure line to it's own sensor, which I'm guessing would cause both sensors to read about half of what they would normally read?

Only if you have a leak.

it turns out that it was only slightly off the standard turbo settings. It was easy to check today because the barometric pressure was almost exactly 30.0 and the value was only off by about 50. What does the value correspond to anyway? I found a chart with millivolt readings for all the pressure settings for the sensor I have, but the values were way off compared to the sensor readings displayed on the EFIS.
