SAFC (air fuel controller)
dude, our ecm is too old to handle these things!
and f.y.i the only thing they are good for is to control when and where ur v-tec kicks in...any other useage is mainly asthetic (spl?)
also, (correct me if I am wrong) but our comp will just monitor the tbi functions, watch the o2 sensor and vaccum/map sensor info...if they read wrong, a check engine light is flashed...and reset just as easily
no...the V-ACF is for Hondas. THATS the one that controlls the V-Tec crossover.
The SAFC is a very simple computer that modify's signals from the Map sensor and o2 sensor. It has a fancy display and memory so you can store settings, play back settings and play around with it in real time.
Both the VAFC and SAFC tune your A/F mixture but a wide band o2 sensor may be needed depending on the resolution of the stock one.
The VAFC is for Honda V-tec engines....its an SAFC with an extra wire for the V-Tec solonoid!
The SAFC is universal...if it has a map and o2 sensor....SAFC will work~!
see this is where you are confused.....
the o2 sensor and map sensors are all good and fine, but the ECU isn't even what you would call obd1...even the machine to check the codes only reads if the parts are good or bad, it's not a numbers game like the new vehicles out there (bmw in particular)
or mebbe i am right out of the ballpark on this one....(although I have NEVER even seen a 2.8 Camaro with any more
electronic mods than maybe a chip...)
also....the only way to "tune" the air fuel mix is if you actually do something phisical i.e. remove/adjust some vac lines....
remember my s-10? I was bitching and complaining that the idle valve is SEALED .... that is the same for most (if not all)
