safc II intitial setting on a 2000
ok guys i have searched and i keep getting threads that are too old, and when i switch the show to old it brings up a different thread that's not what i'm looking for. i got a safcII in my 2000 that installed last night but couldn't get set up so luckily i could just leave it at my shop. i need to know what the intial settings would be for a 2000 with a 3" MAF. if anyone knows please help me thank you.
i tried the 1 in and 17 out and the car would idle but not rev up.

yeah i have a 3"ID MAF. that's why i don't want to use the 1/1 but so far i can't get the car to idle right with the 1 in and 17 out. it will slowly bounce from 900 to 1200 rpms. the car will run fine once i start driving but it won't idle. i don't know why. only thing i've changed was the MAF housing. the car will idle fine with the 1in and 1 out but i don't want to drive it like that for the reason that i don't have a WB. any input would be helpful. this is really frustrating me. thanks for the help.

Add 4-7% more fuel @ idle. You'll sacrifice more 'tuning' points, but it might help.
This seems to be a problem w/ MT folks. Mine goes to stoich @ ~ 7% more correction @ idle and in gear (AT).
When in "P" or "N", I have to add 12-15% fuel to be stoich. Being that you're manual (MT), try adding that. Or add fuel until it idles fine, if it ever does.

i'm guessing your saying that when i use the 1 in 17 out? sorry to be full of questions just want to make sure. thanks for you help with this. i think as far as i know i'm the first one to put a 3" in a 2000, not sure but possibly.
so the adding of the fuel will help it from bouncing at idle?
another thing i noticed is that the car won't rev down as fast as before the safcII and the 3" MAF, is there a reason for that?

There are plenty of 00-01 people that include the 3" MAF in their sigs, but none have ever really commented on its performance, nor their particular set-up.
Before I had the SAFCII settings correct, it was a horrid dog, slow revving, etc. After I got my WB, I was able to see why, it was very lean. Now, even with the setting set-up 1/17, it still idles lean. Couple that with the fact that I do not have a PCV line in between my MAF and TB, which makes it even more lean.
Yes, adding fuel even w/ the SAFCII 1/17 settings was necessary.
Is your car FED or CALI spec? How many O2 sensors do you have?

i ended up just putting the stock MAF housing back in. i'll put the 3" one on when i get my car on the dyno so i have an afr reading. a WB is on my list of parts for the summer. you think with all the work i've done to car already i should of had one. thanks for the help.

The reason I mentioned the O2 suggestion is because it seems as if MT's do not run the same as AT's when it comes to idle control, etc. You're the 2nd person that has tried this in an MT that has had idle problems.
So, I thought maybe it's because your O2 set-up is/was different than mine, and so is your idle control (closed loop / open loop MT vs AT).
It's an easy / quick test to perform. But it's till shooting in the dark w/o a WB.
