I did a search and could not come up with anything so here goes. I am looking at getting an AFC or AFR i was wondering if any one has experience with the HKS AFR. I a debating on getting this instead of the apex SAFC because it says it has more tuning point then the SAFC(11 points versus 8 points) not to mention that it is not as expensive. I can get one for $219 and that includes overnight shipping. Any info would be appreaciated. thanks

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.
always check the rpm operating range for these and their limits of how much they can change the MAP sensor's voltage.

so if you need to go higher than 8000 rpm with your aftermarket cams or need to lean down more than 50%, this ain't the one for you.

Plus the SAFC has a crude (gain change) partial throttle tuning adjustment.

More resolution points to tune is always a good thing.
Their other piggyback fuel tuning devices have 12 points to tune from just as an FYI. They don't state the operating rpm range or change in voltage gain or if they have part throttle adjust though.

this thing does the MAP voltage fake out thing to the ECU like the SAFC/VAFC and so you can only lean down at WOT and still need an FPR if you need to increase the fuel up top at WOT (using this to lean down at the lower rpms after you cranked up on the FP).


PS I know our sponsor doesn't carry this but let's try to support this place shall we? I don't need to be editing your posts for other parts selling websites here right?

Sorry i did not know that i was not allowed to post other websites address. I see people doing it all the time on here if it is a good deal. I have a B&M FPR and crower 403s and my redline will be raised to 8000 rpms. So then your telling my for my application that the APEXi SAFC is better?

no problem. you don't have to pay the $350/mo. at least you know how much it costs to give you free no guessing CORRECT non-noob info at your demand and why we need reliable good sponsors and why we protect our sponsors when we get them. you'd do the same if you think this site is worth coming to and keep up.

use your deductive reasoning based on what I said, what you have, and what your priorities are.

I gave you all the info you need.

you have an 8000 redline. is part throttle adjustment important to you or not?

go from there...
