Drive by wire throttle bodies don't use an idle air valve as the motorisation opens the throttle blade for idle. This is why the ECU does a calibration of the throttle pedal so it can check where throttle pedal takes over from idle position of the throttle butterfly.Would this be suitable for drive by wire throttles?
That was my first thought when I read it, but you'd need an ECU that can handle the throttle (pedal input and throttle output), in which case you probably don't need the separate driver.Would this be suitable for drive by wire throttles?
The stepper motor is a separate part to the throttle butterfly. It opens a valve on a channel that goes around the throttle butterfly. So on a cable throttle the butterfly is fully closed and it's the stepper motor that allows air flow through this extra channel for sufficient air for idle speeds. You can adapt a normal throttle body to be DBW but for the cost of an actual DBW throttle body it's not worth the effort as you need a larger motor for the throttle butterfly with custom fabrication to make it fit a non DBW throttle body.Yeah I understand that.
I'm asking if the stepper motor tech is what is applied to a throttle shaft. Ie, can regular throttles be adapted to DBW.
I did think about that. Now I have the lengths I can make something to replace the bolts. I realise the injectors shouldn't be clamped down.Nice progress, are you planning to make some spacers for the fuel rails for the bolts to snug down on. The injector shouldn't be clamped as such, just held captive between the inj. boss and the fuel rail imo.
