It states in the ads that it has an integrated knock meter.

Am I misunderstanding something somewhere as I though that you can't read knock on an OBDII car?

You can't.:( It works for the older OBDI computers or similar.

It also doesn't read knock counts, but a percentage of knock.

Actually it hooks up to your stock knock sensor if i recall and lets you know if the car is seeing a knock signal.

For the price of the AFC, i would go ahead and get the Emanage instead, it conrrolls ignition.

The only draw back is that you need the profect-e01 boost controller to go along with it

Umm, it won't work on an OBD-II ECU.

E-manage requires a laptop to control ignition.

You can get a second generation AFC for around $300-$350, how much do E-Manages go for??

About $495.00, I think but that's with the basics. I believe in order to get timing control, you have to get the full harness and software.

Are you saying that it bypasses the ecu & just reads it straight off the knock sensor?

I've been pondering this option as well. On the E-manage I'm assuming you can you adjust the fuel with the eo1's little hand held gismo & LCD screen as well as a laptop...I would hope?

Anyway, If is true about the S-AFC II it would be worth it's weight in gold when it comes to "piggyback" tuning just for the ability to read knock. Then again it's only a persentage of the knock & not the actual knock count? So maybe not :?

The S-AFC II does read knock straight off of the knock wire. It is a percentage and so you will need to look for percentages upwards of 140% for getting bad knock counts. Of course, if you had datalogger, you wouldn't need the emanage or the SAFC readings.:)

What I like about the SAFC that I dont' like about Standalones is: 1) I can continuously read and tune as I drive by myself without having a laptop hooked up. 2) I can convert back to stock fairly quickly.

I thought you don't "need" a laptop for the E-Manage. You can do everything just on the regular Profec screen, I though.

Maybe so. I didn't know that the profec could interface with the Emanage.

Yes, the Profect-eo1 does interface with the emanage system so you dont really need a lap top. But its easier with the laptop though.

IN fact on my unit, i can pull up the map for the ignition and fuel and I can program it too. It wont do anything though being that the emange ecu is not hooke dup.



The emange retails for $380. The harness for the fuel and ignition is about $45 or so. The map sensor is about $150 and the hanress fo r map is about $40.

This is etail so you can always get it for cheaper.

Oh by far it will spank the afc.


1. It has 3hr worth if data logging. Thats gold with in itself.

2. It can display A/F ratio unlike a voltage value like the AFC.

3. Has 3 warning , two that show up on the e01, and 1 that gives a 14v output to a wire that you can connect anything to (like a shift light).

4. Can run extra injectors.

5. Has 1 digital input and 1 analog input which you can have an output for each at what ever value you set it to. So i guess you can have NOS turn on at X rpm. (speculating but i think it can be done)

6. You can remove the memory card and share it with yoru buddy. WHen I sell the eo1 for the SRT-4, i set the values in my car then install it in my customers car. Makes it easier to get up and go.

There are alot more features on it but i cant think of them off hand. The BK fish and onion rings have my mind on one thing, food. :)

Won't come close to a true datalogger (which is what I have).:)

Not useful, but the datalogger can display as well.

3. Has 3 warning , two that show up on the e01, and 1 that gives a 14v output to a wire that you can connect anything to (like a shift light).
Not needed. A luxury that will never be used.

4. Can run extra injectors.
Again, not needed unless you plan on running a race car (which the average individual isn't).

5. Has 1 digital input and 1 analog input which you can have an output for each at what ever value you set it to. So i guess you can have NOS turn on at X rpm. (speculating but i think it can be done)
Luxury again. I wanna know about my ECU, not how to blow up my engine with NOS!! :roll:

6. You can remove the memory card and share it with yoru buddy. WHen I sell the eo1 for the SRT-4, i set the values in my car then install it in my customers car. Makes it easier to get up and go.
Done on a pocketlogger and can be viewed on the computer and printed out.

For all that, you only need a knock sensor, timing control, and fuel control, and a logger that logs: rpm, fuel, fuel trims, air flow, air density, timing, air temp, etc.. to properly tune a car with bolt-on mods.

I have all that now for $625.00! :lol:

YOu forgot A/F. YOu need to know A/F ratio to know if everything yoru doing is coming out right. THe warnings are great, you can have it trigger if your A/F goes leaner than what you want.

If your on a budget, go with the afc. I am not so i prefer tha emanage because its easy to controll with my e01. :)
