Question Disparity w/ IFR calc sheets and Edit IFR table?

Why do the injector scale sheets out there (Skiba and Bennight) show the lower number at a lower Kpa and our Edit table shows the lowest number at 100Kpa?

Is this a bug in Edit or the scale sheets?

(I think NoGo answered this for me on the phone a while back but for the life of me I cant remember the answer.)

I assume you are talking about the injector offset table.
What version of Edit are you using? I think in older versions the MAP scale is in vacuum units instead of pressure (reversed values on MAP axis).
Can someone with older Edit version verify this?
So maybe the plots you are looking at are scaled with vacuum instead of pressure...

Ok. Sorry but I don't know for sure with that. My IFR is constant across the table due to vacuum-referenced pressure regulator. Could be the same thing though - vacuum units versus pressure units.

I think the earlier versions of Edit, the IFR table was MAP values in KPA, and now they are vacuum in KPA. Since MAP and Vacuum are opposite of each other, the values are switched.

So you're saying that if you use the calc sheet and enter the numbers from left to right in the IFR table in Edit you are good to go? Thanks for the info.

Sorry, I don't use the calc sheet or have a variable IFR table, so I'm not much help. But I'll bump this one for you...

I just entererd them left to right ignoring the different cell headers, and it seemed to work fine :dunno:
