Gain setting issue -HFS-3

[leman_opc]

Richard, I'm _possibly_ having an issue with my gain potentiometer not having any effect on the injection pattern.

From my brief tests today it looks like medium potentiometer setting results in 1:1 ratio of FAV duty cycle to fuel injectors duty cycle (which I think is OK) and another 90 degrees clockwise potentiometer setting results in 1,5:1 gain ratio, but further turning the gain potentiometer clockwise results in gain ratio DECREASE.

I'm also unsure whether my results with 90 degrees clockwise turn are OK - I thought it would be more like 2,5:1 gain ratio with such setting since I think I read somewhere on the forums here that maximum gain is 4:1 and 90 degrees clockwise is pretty close to maximum setting (maximum is 135 degrees clockwise on mine).

Too bad I didn't check which duty cycle HFS-3 sees (my results above are based on fuel injectors duty cycle calculation as logged from ECU), will do it on Sunday when I have access to the car.

But assuming I will be able to reconfirm the problem with gain setting above what would be my next steps? Is it likely that the potentiometer itself could have failed or something?
