s-afc question
been searching for a week now and just want some straight answers...
1) will u benefit from the safc with ony the minor bolt ons i.e injen intake/exhaust
2) do u HAVE to get car dynoed for max efficiently. If not, what are u supposed to set it to?
3)quoting DIRECTQL
"I would say try it. It's $309 bucks plus the installation and dyno tuning. S-AFC tunes the air and fuel ratio so this won't give you such a big power increase as the ECU upgrade since ECU does timing, does something simmilar to S-AFC (but not as well as well tuned S-AFC), increases the red line and other stuff."
Was your car stock when you got the +25hp gains and is AGP the one off irving park and used to advertise the fact they have the only dyno facility in the area?
$309 isnt bad at all to get istall and runing. I thought it cost a lot more to get a dyno test. oh well.
anyway, thanks guys for all the info i have gotten in pass weeks. just bought 5 speed sc.. big change from the HONDA sceen lol. Kind of want to meet with some of the other SC 300 owners in the chicago area.
thanks again

You can benefit from a S-AFC even if your car is completely stock simply because the factory fuel maps are very conservatively rich to compensate for possible adverse conditions, like running crappy fuel, or being in crappy weather.
The only real way to optimize the S-AFC is to first tune it on the dyno, and then monitor the trends of your performance using a pyrometer (a.k.a. EGT gauge) and an a/f gauge would be icing on the cake. I don't recommend tuning it without any such device simply because you can destroy your engine in a big hurry if you run too lean and detonate.
