Anyone know what channel the HKS FCD for a series 4 is to be set on? I searched for the manual and it only listed nissans and toyotas...

 

i believe it is the second channel. but the guy who did it at fc3s.org, http://www.fc3s.org/how_tos/electrical/fcon.html just cranked it all the way up.

 

yeah, mine's cranked all the way, but my car sometimes seems like it hits a rev limit at 6k and I am wondering if this could be the problem.

Why don't you just test it? My car likes 3.60 as a clamping voltage on my self-built unit.

If you're still hitting cut, then turn it down until it doesn't. I don't like this method since I believe bouncing off of fuel cut to be a very detrimental occurance.

 

S5 TII had it on 2.

Never had a problem for over two years.
