Hi,

I'm looking at the per injector compensations tables (A to D), the scales are obvious (RPM and last Calc Pulse Width), but I'm not sure what unit the values in this table actually are , are they a percentage to add or m/s Value to add to current pulse width (or perhaps a multiplier...), the UI does not say.

Seems most likely it is a percentage to add or subtract, but I cant find a definitive answer, just wondering if ane one knows for sure?

My Rom is AZ1G800S (GVB 2010-11 JDM WRX STI 2.0 6MT)

Thanks,
Ryan

What ive noticed messing about on my 11 sti it is a fuel system composition per injector map stock system rails lines routing and regulator cause lean and rich conditions do to fuel differences in rail and fuel pulsing waves in pressure when u upgrade to aftermarket fpr lines rails and source fpr to middle plenum vacuum source you can eliminate all comps per injector do to mechanically solving fuel system issues
these tables and load comp a b tables are subarus way of bandaiding bad fuel system engineering

Thanks for the additional information, seems like its part of the whole cludge fix for the fuel rail resonance issues, I did also read that with the c**b tunes - once fuel line/rails are replaced they zero the per injector compensations out as well, but only at that point (when the rails are replaced/stage 3), so I've just zero'd them out for now and testing it out.

Dont forget load comp tables 0 those then add a little back mine was only needed from 2250 to 2480 rpm 5% then i used the positive pressure side or building boost side of table to richin tip in boost spooling which got rid of all transition knock and feels much smoother spooling now
