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?

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 ***. VAFC > FMU. As for injectors, bigger ones.

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.
