Ok i just got the Apexi V-AFC vtec air flow converter from a friend of mine in a trade. I really wanna install this but i have not the slightest idea of how to install it to my Crx its converted to obd1 and it has a jumper harness on the p28 ecu for the conversion to obd1. also the engine is a D16z6. and the only code im throwing is a no o2 sensor code. will that effect the install at all? and also my Main question is can someone please help with a write up for the install? Im still a little new to mods and stuff. and i cant find one anywhere!!!! Please Help!!!

 

Don't install that ecu trickery on your car. Sell it.

 

Why? I dont understand

 

Instead of manipulating map sensor voltage, which is what the V-AFC does, sell it and put the money towards having your car properly tuned.

 

Not sure if you have a 'VAFC' or a 'VAFC II'

You could try searching for installation manuals.

Google even comes up with a harness.
Not sure if they still sell them... VAFC is pretty old technology.

VAFC is a nice toy with a cool display. It does let you change the vtec crossover point on the fly which is sort of helpful on long freeway trips.
With that said, you'll still need a tune to run it properly.
You may consider selling it and chipping the ECU.
VAFC only allows for adjustment to the fuel map and VTEC crossover point.
Chipping will give night/day better power results as it will also allow adjustment to the ignition map.
