what is better a apexi s-afc or a hks afr
i have a non turbo rx-7 and wanted to know which one is better i think people say the hks is better you can do more with it and the apexi just looks good.And maybe put some turbo II injectors in.

Basically they all do the same thing. I have the Apexi SAFC tuned to my car. It sits all lit up in the glove box for everyone to not see cause its kinda stupid, "Why do you have that??", "Oh thats cause the stock ECU sucks ***."

I've got the HKS AFR. I chose it over the Apexi because its more versitle, less flashy and $15 cheaper. I dont need some punk thinkin I have a $600 stereo system breaking into my car again, and I need as much tunability as possible for my upcoming project.

The S-AFC works by interrupting the maf signal to the ECU into thinking that you have either more or less air going into the engine. You can set it via RPM's, which you can change to whatever RPM's you need, and has a high and low throttle setting.
Very Good unit IMO

no experience with the hks, but the apexi was pretty easy to install...say about 2hours taking my time. still gotta take it somewhere to get tuned though :-(
i am concerned that it is a flashy thing, so i'm trying to figure out how to hide it, but still have it visible.

Yes, the HKS has 11 adjustable RPM points to tune that can be set in 50 rpm increments, when the Apexi has only 8 points adjustable in 500 rpm increments. The HKS allows for much more precise tuning. Another reason I chose the HKS is size... its tiny. About the size of a mini disc player.

Prolly just need a voltmeter going to the injectors, and to know how much voltage is required for a certain duty cycle.. Pretty much the same thing the S-AFC does I imagine...

Just in case anyone wanted to know I found a place that sells the s-afc second gen. for $275.00. The web site is www.gt-sport.com.
