Reaching out to the brain trust to hopefully provoke a good discussion on this topic. I've just installed a GRT EIS-66R engine monitor; it features an internal manifold pressure (MAP) sensor. I've discovered this sensor cannot be calibrated in software as can be done with the stand-alone MAP sensor used with the EIS4000 product.
With this being the case I would like to touch off a discussion around how one should determine the magnitude of MAP sensor error which exists. We will have some "known" values such as airfield elevation and prevailing altimeter setting as well as reliable and recently-calibrated altimeter information.
Once the sensor error is known, how should one use this information to adjust engine settings to achieve a particular power setting?
The second question arises from my belief that MAP sensor error will ultimately result in incorrect % power readings. For those of us who like to do "apples to apples" performance comparisons it's important that we achieve a consistent baseline in power measurement.
Thanks in advance for sharing your expertise in this arena.
