Zongshen RX3 (ZS250GY-3): Delphi Multec EFI

Weldangrind · 10-07-2014, 10:46 AM

I'm geeking out over this stuff.

I was surprised (and impressed) to learn that Delphi offers a stepping motor throttle body, rather than a throttle cable. That would create drive by wire that is so common in cars now.

I don't want that level of complexity on my bike, but it's cool nonetheless.

The stepper motor in this case is likely for idle speed . I think it would still use a throttle cable for throttle input. Idle steppers allow air to bypass the throttle blade and maintain idle throttle position sensor voltage

Of course, you're right. I got a little too excited.
