BISS screw+DSMLink

[eclipsyco]

Car was running fine and I have already done this with my old biss screw.

So I got a new biss screw with o-ring and cap from mitsubishi, took out the old biss and replaced it. When I tried to adjust it with link nothing happens for some reason my ISC motor which is a few months old is maxed out at -0 at the operative temp of the engine why?

Doesn't matter how much i turn the biss the idle will drop or go higher but the isc stays the same or just move a little bit like -4, -6.

Adjusting the biss with link is the easiest thing on the planet but not in my case I'm probably doing something wrong or what?

I follow VFAQ 2G BISS Adjustment, this video and read a few threats on the video Jafro is logging the isc and the Learn Idle Offset, for some reason I can not log this last one just as a raw value is that normal?

i odnt know if it applies with the link, but did you jump the harness? Again, i dont know if its necessary with d-link.This is the only thing i can think of

If by jump the harness you mean ground it then yes I did, with link it can be done just by clicking the 2 boxes under the misc tab.

So guys I found out that if I screw the biss all the way in the ISC goes to -20, I haven't touch anything else why is this happening now... anyone? possible vacuum leak? my boost guage shows vacuum at 18in/hg.
