Need to tune my SAFC
 

Hey all -- I am planning a trip down to Garland, TX to the Rotary Performance shop... supposedly this is one of APEXi's Power Excel shops that would seem to be the best at tuning my S-AFC, considering they make them!

I was wondering if any of you had any ideas as to where I could find something else that is closer? Garland is about 3.5 hours away from me so I was just wondering if it would be worth going to a certified APEXi shop or going somewhere else that has experience in this area. Thanks...

Any shop with a dyno should be able to do it. The S-AFC is very simple to tune.

Installing and tuning a SAFC is a no brainer. Any shop that has a Lambda sensor hooked up to the dyno can precisely tune the SAFC. I've done it and it knocked off .05 seconds in the 1/4 mile. Leave all the settings at default (0) until you get to the dyno shop.

.05 sec huh? That could've been either that the tuning didn't do shit and you shifted better, or your driving was worse and the tuning helped more... I'd figure that .05 is a little small? Maybe .5? Actually .5 is too much but you know what I mean.

I've got everything set on the S-AFC to where it should be, but I haven't gone into all the other fuel curve stuff. I just have the (4cyl, up and to the right) (06 in and 06 out) (Sensor Type: Flap) - that's all... sometimes it's running only 2 over stoich and sometimes 3-4.

Dont really go by the A/F gauge I only put it there for a light show lol....you need to use a wide band o2 sensor.

Damn...I meant .5 sec.

I was thinking that the people with the dyno would most likely have a spare wide band o2 sensor that they could hook up. I don't really care to spend $450 at the moment :D

A Horiba Lambda sensor is an O2 sensor like I said earlier and it doesn't cost that much to have a bung welded on to use the O2 sensor. That's how you tune the SAFC not by your A/F gauge.

Yeah I know, I'm not going by the a/f guage. It simply tells me that it is a bit rich, and even if it wasn't it would be best to tune it for a large HP gain... If they have a spare wideband, they could tune it with that, and put my old o2 sensor back on... even though the a/f guage wouldn't read very accurately I would still know that it's tuned correctly.
