Installed ApexxiVafc on NA motor & CEL reads Fuel/Air monitoring? Help
obd2 scanner reads fuel/air monototing for check engine light on. What could it be? I went over the wires for the vafc & it's hooked up correctly. Help.

What ecu are you running with the AFC and please list all the settings on the AFC. If the afc is not setup right you can get all sorts of strange problems. your sure there isn't any loose wires?

No loose wires tripple checked them. I have obd2 ecu on a 99'civic si, no boost yet. 1000 rpm 0
1500 rpm 0
2000 rpm -1
3000 rpm -2
4000 -3
5000 -5
6000 -6
7000 -6
8000 -6
I used these settings by subtracting from the settings that FAQ for the afc said to add for 450 injectors. All the other settings in the afc are set by what the manual said. Car sel=4cyl, throttle=arrow pointing up, sensor #=06 in, 06 out. I have vtech engagement set at 4400 rpm.
vtec unmatched fuel correction= Hi<<L: +-5%, Lo<<Hi: +- 3%.
Throttle position wide narrow setting Lo=10% Hi=50%. These are the exact settings on it. Has anyone else had this same problem? air/fuel monotoring CEL on= scanner result.

Piece of ---- apexi instructions came in japanesse. I had to print out the instructions in English & the wiring diagram wasn't too clear. Luckily I was able to install it but there wasn't a location for the vtm wire hook up on the instructions I printed. I found an update with a clear wireing diagram and a location to connect the vtm signal wire too. Hopefully this vtm wire not being connected is the cause of my CEL being on. Time to whip out the soldering iron again. Piece of ---- companies thinking I know Japanesse.

What injectors are you using?
Stock? Or 450's?
If stock all the settings need to be at 0!
If 450's all the settings need to be at -46 which is the same as the stock injectors, if you are boosted you need to be at -36 all the way across.
