do you guys really think that its needed to have this? or do u think that a a regular af guage will work? the benifts are The HKS AFK is an electronic monitoring device that displays two of the most vital engine conditions; engine knock and air/fuel ratio. Knock occurs when there is abnormal engine combustion, known as detonation, caused by a combination of improper A/F ratios and ignition spark. This can rob power, reduce engine longevity and even lead to catastrophic failure. The A/F Knock Amp utilizes the factory knock sensor allowing you to monitor, in real time, engine knock visually and audibly via headphones (not included). A warning function can be set for both engine knock and air/fuel ratio where an audible alert sounds if the preset warning is reached.

 

Are you asking or teaching

 

just asking and tht what i knw

 

Its what you copy and pasted from the HKS website.

 

yes it is lol

 

fial. lol.

 

ya it is but wondering if its worth it or just get a afr guage

 

if you are not going to use it for feedback to the Fcon then get a gauge

 

so wht should i do get guages or get amp

 

You FAIL on your spelling! LOL

 

Just read what people are posting.

 

I don't have an FCON, but IMO it's one of the FCON's best features, particularly the new version that allows dual sensor input with one control unit. If I were running the FCON, I would have it hooked up with feedback for closed loop control. Given what I've heard about the quality of the knock amp, I'd be much more willing to sport an aggressive tune with the knock amp in place. If you're not looking to break any records or push the car to the limit in extreme conditions, then you can probably get away without it.

 

I have an hks afk knock amp with optional sensor to monitor both banks. It' nice to know exactly what the af ratio is at all rpms and with both cylinder banks. If you do upgrade to fcon u will be happier than spending on gauges.
