Does anyone have information or experience with converting a fly by wire thottle body to a cable controlled thottle body while maintaining the OEM PCM? I see cable controlled TB's available, but don't see what it takes to use them. Maybe a stand alone ECM??

Thanks,

 

Not possible because there's lots of things that the computer reads and relies on based by the fly-by-wire position.
You would have to design your own pcm program in order to do so. That or go to carburated which....who the heck would wanna do that???

 

why would you want to convert?

 

because of the extremely select few people that have had their gas pedal stick to WOT and cause accident. This is what has happened with the Prius cars.
For such isolated incidents, i wouldn't even bother. Sure it's an unsettling feeling, but if you think about how many millions of Rams there are out on the roads and only a handful of stuck throttles. I am not worried at all.
You just need to think ahead of what you must do in those situations...such as turn the key off and coast to a stop or throw the truck in nuetral and slow down asap. Some of the few things people dont think of when they panic.

 

Mopar sells one I believe.

 

No they don't. They MAY sell a cable to fly-by wire "upgrade" harness..if you will, but not going backwards in time.
So that would mean;

cable--->fly-by-wire
but not
fly-by-wire-->cable

No reason they would advance to a newer technology to sell an outdated one aftermarket. That would pull in very little profit for them. Most peopel want to advance their outdated rides.


I'f someone else finds other corroberating eveidence please let me know.

very bottom of the page?? I am not for sure if this is it. But I know they are out there are people are running them.

 

The reason to convert is to get actual WOT when racing and eliminate the power robbing torque management!!!

 

That's what the Superchips tuner is for right?

To use that T/B you would need to buy thiese things;
P5153689Throttle Body 392 Hemi Crate Engine $495.00
P5153606abWiring Harness, 5.7L Hemi Crate Engine, Carb. $706.00
P4510342Non-Programmable, 5.7L Hemi Crate Engine, EFI $2189.00 <--This is just the PCM not an engine.

So, it's re-arranging the entire sytem, it's not a plug-play unit as anticipated by Redtruck_VA which is what I was reffering to.

Now, there might be a way to re-configure the factory pcm to make things work, but it would incorporate heavy software knowledge and the system to program it with. Not something I would be willing to do just to sleep a little better at night.

 

I saw another cable driven TB that was 90mm bore. These appear to need a stand alone ECM. The real down side is they are all expensive and the entire truck would need to be retro-wired including a new dash and steering column, but the engine would have unlimited tuning without compromise. Now if the OEM PCM could be left in place to run the truck's electric's, trans and a stand alone stacked in to manage the engine it would be a little better, but still expensive. I'm just playing with ideas to see if anything interesting has been attempted along these lines. My 03 has been a PIA with doing anything with the PCM so I reaching for something other than the OEM PCM for a solution. Thanks for the input...

PS this is about tuning not stuck gas pedals......
