What do you think about drive by wire throttle for sleds?

[smokingcrater]

One thing to keep in mind, if you have a fuel injected engine, its already drive-by-wire. All the user can do by manual intervention is add air. You need fuel for power, and that is controlled by a computer reading the throttle position.

In any case, it all comes down to tuning. I've driven vehicles that had incredible DBW systems, as well as ones that were intentionally de-tuned and sluggish. A good system is fully capable of snapping open the throttle plate faster than your muscles can react though...

Same deal there. I work for the blue oval, next time you're tinkering with your trucks under the hood, have a look at where the throttle plate is and where the intake ports are. They seam close in relation, but if you took the intake manifold runners and extened them out in a straight line, you could see how long they really are. While I agree from factory the throttle action is lazy and tuning does change that. But the long manifold length used for building torque has a huge effect on responce. The older 5.4 actually has an actuator and a "throttle plate" at the intake ports to control airflow. The 6.8 v10 had a similar deal but actually changed the length of the intake runners.

Ever need to know info on your trucks, pm me

Thanks for the additional info. The tuner I bought improved the power and gas mpg. I was really impressed! I get around 12-14 around town and I'm okay with that as its a big, heavy, un-aerodynamic box compared to my '00 Chevy. I got almost 18mpg with it between Anchorage and Palmer but that was pure highway and part of it was downhill. The new 6.4 Ford Superdutys we have at work are getting under 10 mpg around town. Crazy! My brother drives one and I asked him how many hours he lets it idle around per day and he said he doesn't. Too bad they dropped the manual trans for the Superdutys, the manual shift auto setting doesn't seem to do anything in the real world.

But back on topic, I don't know why anyone would want drive by wire on a sled? It's just one more thing to fail and in its exposed location, I don't think it is a wise idea. I don't think I've ever broken a throttle block but I've snapped off plenty of throttle flippers. I wonder if the 900's flipper is more $ than a regular one?

Well you want one becuase you can get increased throttle response, programable throttlerespons (as in a setting for the wife, for the kids and for you) You could start getting traction control with throttle adjusting if you solve the clutching issues and so forth..

I would actuallt like to se it as I think it the only way to go and the sooner your building it the sooner you will get a solid product. Im sure all manufacturers have drive by wire sleds, question is who will feel secure enough to let it out on the market first..

Fly by wire will probably become more common on EFI sleds.

No one thought plastic skis would ever be as durable as steel, but just about every sled has them today.

It's funny how time changes our perception.
