You are probably correct N= eil.  I was thinking the scale factor was used differently on that func= tion.  Yes, try increasing to 3.78.   To get the first initial inc= rease, bump it up by something over 50% which will cause the EM3 to add 1 + t= he percentage indicated.

Tracy,
            Not s= ure=20 how your monitor counts, but changed the scale factor from 1 (standard) to .= 265=20 as suggested  (divided 1 by 3.78) and now at 2000rpm I am getting a rea= ding=20 of 0.5 gal PH which should be litres!!  Sure makes it=20 economical!    Seems like I should multiply by 3.78 as that w= ould=20 seem more like it.  What do you think ?  Neil.

I'd start by dividing the current scale factor of FF channel by 3.75 , p= lug=20 that value in there and see if it looks right. I'll try it on the bench when= I=20 get a chance.

ONLY?   6300 is at the HIGH end of normal static.  I w= ould=20 be more concerned about over Reving at top speed if this were a 200+ MPH=20= plane.   It will probably be about right for the glastar=20 though.
