I'm looking into getting a fuel piggyback soon, I don't like the S-AFC's flashy screen or it's high price. That led me to the HKS S-AFR, and I now have one on the way to my house.

Does anyone own or have any real life experience with an S-AFR? I've read about some guys that use it, they like it, but it is far from popular... why?

And please don't give me answers like "The S-AFC must be better because it has a pretty blue screen!"

 

hmm... guess not.

 

OK, well I now have one, and installed it into the car today. The digital tach readout on the thing while cruising is pretty neat... but I'll post some more detailed opinions after tuning it.

 

S-AFC is way better.

It has a blue screen.







Never used the HKS. Let us know how it goes.
