VAFC to control fuel on a non Honda?
 
I was going to get a VAFC to control fuel for my Toyota Celica (trubo).

Originally I was going to use an FMU but thought that since I was able tyo get a good deal on the VAFC it would probably work better.

I know its normally used to control VTEC engagment but will I be able to use it in some way for my obviously non-vtec Celica?

Yes, you just don't hook up the 2 wires for vtec. Make sure to get bigger injectors too since you aren't going to use an FMU now.

Would it be possible to use an FMU and the VAFC together, as the ultimate dream team.

For this application is the VAFC going to be a superior system to the FMU?

Any recomendation for the injectors?

people used to use them together, it blows ass. VAFC > FMU. As for injectors, bigger ones.

Just get larger injectors, depending on how much HP you want to make. Keep the fmu out of the equation.

Dumb question...does a celica run a map sensor or a maf sensor? I have yet to see a vafc that will work on a maf or kharmann setup.

Actually...VAFC run much better on the MAF as it actually measures air flow instead of just being part of the calculation.

When you run a AFC on a MAP system, it is a total "hack" which rescales the signal going to the ECU.

Well right now its just going to be IF I get the VAFC. I paid the guy but havent heard anything from him in 2 days.

EDIT : Im not sure which one it has.. I seem to think its a MAP

well ive got the same question. ive got a vafc layin around and was hoping i could use it in my yaris, which has the 1sz-fe engine. it uses a maf. so will it work with the maf? my real q is that, what number would i have to use at the sensor 'in' and 'out' section? and what would the throttle signal be set to?

Yaris = 1NZ-FE

You should be able to get a ECU wiring pinout from the dealer or online somwhere.
