This sound just GREAT for those of us with s/cer's(HKS Super AFR)

Sounds great!

The HKS Super AFR is the very first airflow meter correctional device in the industry with a built in CPU. The advantage of having a built in CPU is that instead of making corrections to the airflow meter voltage/map sensor, the characteristics of the airflow meter/map sensor is inputted in the CPU so it can calculate the most accurate amount of air flow. Since the correction will be made to this specific intake volume, the correction ratio of fuel will be precise and proportionally correct. With an illuminated digital display and face mounted adjustment controls, the compact Super AFR is a simple to use fuel computer that offers many of the advanced features that were once exclusive to full engine management systems. The L.E.D screen is utilized to digitally display all adjustments as they are entered along with RPM and fuel % adjustment (over baseline) in real time. The Super AFR is compatible with virtually any fuel-injected vehicle, 12Volt, 2-12 cylinder vehicle that utilizes a hot wire, Karmen Vortex, airflow meter or pressure sensor. The internal CPU allows it to be versatile and utilized on many of the newer type airflow meters.

The air/fuel Ratio Correction function of Super AFR allows complete fuel curve tuning by offering eleven points between 650 and 8000 RPM of adjustment, that can be arbitrarily moved in 50 RPM increments. Each point of adjustment offers a tuning range of 50% rich to 50% lean of the factory baseline setting in 1% increments. Also incorporated in the Super AFR is the Idle Correction function, where Idle fuel mixture can be adjusted from 50% rich to 50% lean of the factory baseline setting in 1% increments within the idle range of 650-1500 RPM. This offers the ability to adjust idle air/fuel ratios as modification progress and require further specific levels of tuning to compensate for the characteristics of high lift cams and/or larger injectors. The response function, similar to the one in the VPC, allows for adjustments to the fuel settings upon throttle inputs to improve driveability and performance. Much like the corrections made to the idle mixture to compensate for high-lift cams and/or larger injections, the response function can also compensate for differences in fuel requirements upon initial throttle input as airflow characteristics are changed from high-lift cams, larger injectors, and bigger turbos. In detail, the response function allows for management of engine response in milliseconds with six points of air meter signal adjustment between 650 and 5000 RPM that can be randomly moved in 50-RPM increments. Additionally, an Electronic Idle Stabilizer function (EIDS) function, which buffers the dramatic airflow meter signal fluctuations, prevents the engine stalling or stumbling effect associated with the sudden imbalances in the air/fuel ratio of airflow meter-equipped vehicles that utilize discharge blow-off valves that vent to the atmosphere.

Warning: Due to the nature of this product, a lean air/fuel ratio can occur which may cause detonation or other severe engine damage. HKS strongly suggest consulting a trained technician before the purchase and use of the AFR.

Sounds like a fancy S-AFC.
Far better. far. Make the car run proper at all points possible. Get another 12hp...at least thats what paul got out of his car with it.

Thats pretty good, but does it do the "S-AFC Phenomenon?"
Paul din't say It did anything bad. INfact he seemed rather happy with it. I have a friend that has a super afc and he has no probs with his, so what phonomenon is it your talking about?

apex's afc is better. cause you can read throttle position, air/fuel voltage, rpm, and mass sensor HZ's- (amout of air flowing through mass sensor). and it looks 983648765 times better than the HK$ AFR. chicks dig-it!!

But it only has 8 selectable points at which to adjust fuel and can only be changed by 500rpm where as the hks has 50rpm and 11. I come from the school of thought that more is better And looks? Well you prob woun't see it when i put it in so who cares.

AFR can also be had for about $250 but it doesn't have as much data acqusition/display options as the AFC, as someone already said!

just a couple more settings will give you a slighty cleaner hp curve, not worth it over all the other stuff i mentioned. but that is my opinion. 99% of the people I know use afc, NOT afr. actually 100% of people i know use afc. and thats a lot of damn people including dsm, supra, 300's, 7's, vr-4......

I'm not trying to knock it at all. It's may first time putting a fcd in a car. So I'm looking everything over. I'm not sure that I really care to have all that data displayed not much I'm going to do with it. Once the shop tunes it in You probley will never see the peiece again.

Let me re-phrase..."Cheston's S-AFC Syndrome."

ECU learns S-AFCs manipulation and puts a halt to all of it...resets the S-AFC and you must start again ? Unsure but I talked to GHOST on Hemstead Turnpike, and he has a S/C A/T and has the S-AFC and same sh*t happened to him.
Did cheston or why not try to get cheston instead of third hand info do any ecu mods? If not do you think moding the ecu would help from having the ecu learn and "correct the s afc.

I think Cheston was on stock ECU w/ S-AFC to supplement his Fuel Delivery Curve. The 5th gen has no ECU mod.
It's the Nissan ECU, its a stubborn piece of electronic wizardry.
Theres ecu mods out for the 5th gen.

JET ?
Yeh and don't get into that it don't work vs work thing. Its vary debatable. Most of the ones that have them don't have much else dun. Jet is a reputable company. Even if theres no hp gain remaping the fuel and ignition and a higher rev limit is good enough for me.

Jayson, whatever floats your boat man.
I'm just trying to prevent a another discustion about the jet chip, thats all. Trying to keep it somwhat on track.
