I put a VAFC into my CRX with the stock computer. I hooked everything up, but the throttle position meter isn't changing with how I push the pedal down, it either reads 63.7% constant or 91.3% constant.
The other problem is that the RPM is readong 3000 RPM at idle and at 3000 RPM on my tach it reads 9999. The pressure reading is perfect and right where it needs to be. Is my voltage wrong, and that's why I am not getting the proper readings, or is there something I have to do with the VAFC?

 

it's probably hooked up wrong

where did you get your diagram from?

 

The wiring from the throttle positon sensor was wrong. I fixed that, but when I press the throttle down the voltage doesn't change. The RPM problem is still there. My car has 2 crank position sensor wires, and one wire is the wire that I am using now, and the other one shows zero RPM all the time. I used the VAFC instruction manual, plus the CRX factory service manual to hook all this up, but I am still not getting a proper signal.

 

Are you sure you have the VAFC set on 4 cylinders, and you have the arrow pointing the right way? Thats what your RPM problem sounds like to me.

As for your throttle problem, you need to reset the VAFC, and as soon as you turn it on hold the throttle WOT for 10 seconds, and leave it closed for 10 seconds. Then set the correct number of cylinders, and sensors. The sensors should read 06 06.

 

I have done that. The arrow is pointing to the upper right. The CYL. # is set on 4, but what does the sensor type do? Why does it have to be on 6?

Keep in mind that I am using this on an ECU and engine that the VAFC does not give wiring diagrams for. I am using this on the D16A6 motor, and just setting my Vtec crossover after my redline. So I'm always runing on the low cam side, but is the sensor voltage different? Is that why I am not getting a correct reading?

 

sensor type needs to be on 4

you have to set the throttle by make the arrow go up and not press the pedal for 10 secs, then u got to put the arrow down and press the gas for 10 seconds,

or vice versa goto apexi website and download the manual then double check all of your wiring and connections.

 

Sensor type should be 06 06. I didn't ask why, but do any kind of search and that's what you'll come up with.

 

Does the VAFC work on a D16A6? Because if I can't get my RPM's to read correctly then I might as well go **** on my $300 purchase.

 

I'm wondering if you even spliced into the correct wires. You said you have a VAFC? Why are you using that if you have a A6 motor? W/out VTEC, you should be using the SAFC.

 

I agree with Todd, I thought you said Z6. You shouldn't have even hooked up the two VTEC wires coming out of and going into the VAFC. If you did, theres your problem, because they don't exist. Go back and redo all your wiring, without hooking up those wires for VTEC. If that still doesn't work, then you should just take it out and let someone with some electrical knowledge install it.

 

There's no reason to insult my wiring know-how. I did not hook up the Vtec wires, because you're right I have no Vtec... I got a killer deal on the VAFC, and I plan on in the future switching to the Z6 head, however at this moment I am using the VAFC with the Vtec crossed over at 7000 RPM, which is after redline. I also went and rechecked all my wiring, I redid the splices. ALL the feature work, even leaning and enriching my mixture using the VAFC, HOWEVER as I have stated before I am getting an inaccurate reading from the RPM and voltage from my throttle position sensor, which is running .050 volts, but there is no change in that voltage when I work the pedal.
I also downloaded the manual for the SAFC, but the wiring diagrams are the same and it says basically all the same installation procedure as the VAFC does, except minus Vtec. Now it doesn't matter wheather or not it's a Vtec or a non Vtec AFC I should still be getting a change in Volts from my throttle sensor, and an accurate RPM reading. Is the voltage from the crank position sensor any different in the A6 than in the Z6?

 

soundman - Your sig says you have a mini-me but you're saying you have a stock A6?

 

i was about to put z6 on when deal fell thru, so i put A6 head back on.
Did you swap computers when you did your mini me swap, or do you have A6 computer?

 

I still have the PM6. I'm thinking of getting a harness converter and switching to a P28.

If you follow the diagram on this page: http://www.geocities.com/bing_....html you should be alright.

But if you're not gonna swap your head or get a VTEC motor I say sell the VAFC.
