I've had my V-AFC installed for about 3 months now, and since I've installed it I've been throwing the 02 sensor, MAP sensor, and VTEC codes, while a local shop told me that the ECU is just "pissed off" because the V-AFC is overriding it, but the Apex-i site says that if codes are thrown that something isn't right.

Well that yellow CEL is really getting annoying, and lately I'll start the car up and it won't come back on for a few minutes, when other times it'll be on right away. The V-AFC seems to be working properly and doing its job, and appears to be hooked up right.

Any ideas on how to get rid of the CEL?

 

if the ecu was getting "pissed off" w/ no other problems, you'd be getting a CEL 13 for barometric pressure. Maybe your wires aren't connected as solid as they could be?

 

yes go back and double and triple check the wires.. solder and tape the wires, the connectors that come w/ the vafc suck.. i wired mine up had a code for the map sensor, rewired it completly, code went away.. my boy had a friend install his vafc into his 00 si and it would stall out and **** sometimes, i traced the problem to the shitty wiring job, i literly touched the wires going to the ecu and the car died..

 

Should I just say the hell with those stupid connectors and solder everything?

 

yes get rid of the connectors and solder and tape all the wires.. ive always soldered and taped wires and very rarely had problems with them at all
