Hello,

I have a 2006 E-350 SD Step Van with a 5.4 engine.

It is possible to governing the top speed? Can a Ford dealer programme the ECU?

 

Welcome to FTE.

It is possible, I'd just call a Ford dealer and ask. The company I work for had a couple new E150s delivered--2011s iirc--and right on the window sticker as an option was listed "65 MPH maximun speed" or such, and them babies stop right at 65....

IF the dealer has no clue, try another one, maybe try a dealer that sells commercial trucks.

If that fails, you are looking at an aftermarket chip or reprogram, like this outfit:

Derive - Vehicles Supported | Derive Systems

 

Sounds familiar.....5 Star seems to be the only one that could fix mine so far.......about 400 bux....gonna try a commercial dealer first , good idea

 

I never know until I plug the VCM in and check if speed limiter can be raised.
Some don't have the option at all,it is set according to the speed range of the equipped tire from factory.
If it's limited at 65 then it is likely because it was a fleet purchase and had that option.
A buddy had his truck programmed for fuel mileage by the fleet company they use and it installed a limiter.
I tried reprogramming/updating the pcm and it made no difference and had no option for changing it.

So,find a friendly dealer and they can try is about all they might tell you.
Still gonna cost the diag/pcm programming fee even if they can't.

 

If the current PCM can't or won't accept a limiter being disabled or defeated would a new (used) one suit the need?

 

"Technically" the speed limiter is not likely a hardware limitation of the pcm,it is a software limitation.

The proper procedure for installing a new pcm would be downloading the data from the old pcm into the ids (scantool) and then uploading into the new pcm after installing.
IF the limiter is in fact part of the factory/fleet programming than this would likely make zero difference and the limiter would still be there.

IF you installed the pcm from another vehicle that did not have the limitation in the software than you should be just fine.

However,I doubt it would be plug and play in my experience. The security would need relearned and other features would likely not be correct.

I should insert here that I have ZERO experience doing anything aftermarket on a Ford.
I have built,swapped and programmed GM's for years and know most of thier stuff pretty well. But I have yet to really start digging into any type of programming on Fords other than being aware that my Hptuners will program them (haven't used it on one though) and knowing that thier operating systems and strategies are as different from GM as an Apple computer is to a Windows PC.

I buy the local pullapart out of LS and other gm pcms pretty often though,and they only run me $14.99+$2.00core.
At those prices I would just get one as close as possible and try it out.
Much cheaper than any other option I could think of.
