Apexi S-AFC II Tuning Advice
Before I go any further I did do a search and was not able to turn up what I was looking for. I posted this here because there was not a section for the "S-AFC" in the engine management/tuning fourm.
I am looking for a set of install and tuning instructions foa my new S-AFC II I just got for my birthday. I know Buschur had one at one time, but I don't think my G/F got it from them or I would have gotten that with it. Does anyone have one of those, or any other place to find a map?
My motor mods that would affect a map are as follows
HKS Intake
HKS D-pipe & Cat back w/ ultimate racing cat delete pipe
BOV
Boost controller
PWR FMIC
Any help would be appreciated!
Thanks!
Tom

Hi,
Well if you look at the big thread started by Vivid about sharing SAFC settings, you can get some baseline maps. However, most people will tell you that you really need to tune on a dyno with a wideband O2 sensor. Some of those maps seem pretty aggressive and may cause a lean condition on one car but work well on another. I have found that weather plays a big role as well, esp here in New England where the temp fluctuates a lot over the year.
In general, the car runs pretty rich above 4500 rpm or so, but since you have an open element intake, it can actually run lean in some spots.
In my car I richen slightly (+1) ~3500-4400, then start leaning progressively from -3 at ~5200 to -7 or so in the upper rpms. I check my knock sensor reading on the SAFCII, and I try to make sure I don't get readings above 20-40 or so peak. I hope to tune it on a dyno with a wideband later this year. I currently have no A/F data, no dyno numbers, and no dragstrip times, heh.
On a side note, you may want to get an upgraded fuel pump, there are several posts indicating it can be good insurance.
Take care,

Here's that big thread started by Vivid:

Also do a search on Walbro and you'll see that the fuel pump may be a good idea once you raise boost and have a full turboback.
