does anybody know how to set the fuel part of a field sfc-vtec controller
i dont have the book for it and really dont have tuning money due to kids taking all my money!!!
any help will recieve major rep points!!!!
motor is a sohc vtec with bolt ons
and boost coming next week!!!

 

You can't just say, run +3% fuel at x rpm for your setup without seeing a air/fuel output using a wideband oxygen sensor.

The controller is useless without a wideband.
Btw, setting vtec early won't make you additional power, you can actually loose power.

 

its not set too early i was able to figure that part out at the track
my stock p28 turns it on at 5800 its set at 5000 now that was where my best time was at
ive tried it at all the rpm settings and ive found that 5000 rpm was the best i just cant get the fuel part down
so what is the deal with the wideband
is that just at tuning or is it something i have to buy
i do have an air/fuel guage

 

What is a wideband oxygen sensor?
A wideband oxygen sensor is a sensor which allows you to monitor parts air to fuel. Most people have the preconception that a basic autometer air/fuel guage using the stock oxygen sensor in their vehicle will give them all the information they need about being in a lean or rich condition. This information is false, the factory narrowband oxygen sensor will not provide you with an accurate reading because the oxygen sensor is a narrowband sensor which does not have a wide enough of a range to accurately sense air/fuel mixtures needed to properly tune a vehicle. The purchase of a wideband oxygen sensor is not required due to the fact that almost every tuner provides one with his services etc.

 

oh ok so its usually included in the tuning then hey thanks
i guess i have to save up and find someone to tune it then
ive just heard that its like 500 bucks and to me that seems like a little high but then again i guess its not

im getting ready to boost it next week i have everything just have to get the time to do the install

 

Tuning a vtec controller won't cost you $500

If you are going boost, you should consider selling the vtec controller & getting your self a management solution, you will probably want to convert to obd1 at that point.

 

i am obd-1 i have a p28

 

Great, your one step ahead of the game.

ok i know about chips the last time i got a ecu chipped i spent 100 bucks and the ecu rev limit ended up being 5500 and the guy wont fix it or give me my money back ive had bad experiences with them and the guy was here on tr
he wants me to drive back to orlando and leave my ecu with him for another week or two and i dont have an extra one to drive on
the last time i was out of a car for over 3 weeks
and the thing still isnt right and i dont have the money for hondata or any thing like that if i take to a shop to get tuned for my boost it should be all ready to go right?
i just dont know where to take it too
im used to doin it all my self i get scared when other people start doin stuff to my car
