I am looking for some tuning help from people who own or have worked on a CSC.

I did a quick scan at idle of my LTFT. They are at 16.4. I heard with an aftermarket cam that they will sometimes go this high. Is this normal?

My 02's at hard throttle(55% I couldn't get to 60% because of all the damn traffic) ranged between the high 800's to the mid 900's. I don't know if that's a little low so I might richen up top just a little to be safe.

I had my afc1.1 at 13467 I will probably put 8 on too now to richen the o2's like I stated earlier. What do you think?

My dial is at -4 on 94 gas and I've seen no KR so far. I can't really give you much more than that right now. I have some runs recorded but the Autotap wont let me view them and I can only watch so many parameters while driving.

Is this enough info for some minor tuning help?

CSC 3.4", HVII, Stage 1 TB, VS cam

Thanks

Frank,

Your best bet is to work with Matt M directly on all CSC tuning. I know that I have an ICCU and my cam specs are as follows:
Duration .218/.230
TIL .538 w/ 1.6 rockers TEL .544 w/1.7 rockers

I tuned my car in on the ICCU so my LTFTs were zero and then, when I went WOT, my O2's were over 1000. I did my 4.8whp dyno being that pig rich. Matt gave me settings to go off of as a baseline and we got the O2's down to where it was supposed to be. He recommended tuning by the O2's at WOT, then to keep the other ICCU settings withing 5%. The AFC will most likely be similar but I'm not sure if you need to do it this way with the VS cam.

Which blower are you using and which pulley? What compression are you running?

I am have the NOVI 1000 with a 3.4" pulley, no IC. I just logged some of my runs and will post them to see if you can get any info from this.

ITA A/F TPS 02 LTFT RPM KR

IDLE 35.5 14.7 9.4 820 4.7 1830 0.3

CRUISE 22.5 14.7 25.1 720 -6.2 2410 0.3

WOT 1 22 9.7 67.1 910 -7 4785 0.0

WOT 2 22 11.4 76.5 880 -7 3225 0.0

The reason I listed these were because of the kr. It's 0 then a blip of 0.3 and then 0 again. I don't know if this is a shift or what. Any ideas? Most of the time my LTFT at idle are 16.4. I've heard this happens with a bigger cam.
