Having trouble with the air/fuel ratio. PLEASE HELP

I have ITR #01-689; and since i added my intake, 4-1 header, and Exhaust; i've been having thlottling problems and i'm running extremely rich in VTEC. I got an Air/Fuel Ratio gauge from Megan Racing, and i've been having problems w/ the wiring. Does anyone know what wire is the Air/Fuel Ratio signal from the engine. the diagram on the gauge's box says temp sensor, but the air temp sensor does seem to be the right one. Any help would be appreciated.

Honestly - an a/f guage won't do you any good. Instead spend the money on an aftermarket tuning modifier like a Field SVC (VTEC & Fuel control) VAFC (I've never cared for them much) or even nicer Hondata setup.

You should then find a decent tuner to tune your car on a dyno. If these options are not available to you, then at least make sure you reset the ECU. This 'reset' will allow your ecu to relearn what air volume is flowing through the system and make some small adjustments to the system. This should help your idle and overall performance.

doesn't resetting the ecu only involve removing the negative terminal to the battery. Because if so i've already do that a coulpe of times, so i didn't get shocked while tampering with wires. i don't know how long you to let the car run before it will relearn the engine parameters.

*Knowledge's ECU resetting system*

-Unhook the positive side of your battery cable from the battery
-sit like that for a minimum of 5 minutes
-rehook the batery cable up for 5 minutes
-start the car and let idle for 5 minutes (Touch nothing, and make sure everything is off!!!)
-Everything should be good to go at this point!
