at 2500 revs
32.256 x 1.8 = 58 % its asking for 50.2%
7.8 % percent difference
Difference between commanded 50.2% and actual 58% - percent error 15.54 %
Google says
The acceptable tolerance for the error between commanded and actual EGR (Exhaust Gas Recirculation) is generally 5% to 10% while driving. If the error consistently exceeds 15%, the Engine Control Unit (ECU) will typically log a fault code (such as P0400 or P0401)
if its saying you're aloud 5 - 10 percent .. your ok .... if its saying the difference between the two, in percent difference, then your over
Make of that what you will, others with more experience will hopefully comment
all the best.mark
