Adjusting thres and gain having no effect
 

Hi All

I have a Golf V Gti, have had an expert friend install the HFS 3 for me (im mechanically challenged - all i can do is drive - :) ) The system was working fine, however it was spraying a bit early. i attempted to adjust the threshold to spray a little later and cut down the gain so it sprays a little less. However since this any adjustments i do have no effect, the dials thres and gain turn but have no effect on the system
I am very confused now, please can someone help.
Thanks
Zed

Re: Adjusting thres and gain having no effect
 

The gain will be at "x1" from the trigger point. As the IDC climbes the effect of gain will increase.

Starting IDC trigger at a higher point won't inject more, so no need to decrease it.
