replacing the PP vacuum gauge with boost gauge?

[dastefster]

Hey guys,

So I'm not 100% sure if this is the right section to post this in, but anyway.. I will be installing a SC kit on my 15' PP GT in the next couple of months and I want to install a boost gauge along with it. I'm not a huge fan of gauge pod pillars or the almost pointless vacuum gauge that comes in the car. It would be AWESOME to be able to just pull out the vacuum gauge and pop in a boost...but I fear this will be no easy task. I've heard that the stock gauges are are not "individual" but are 1 unit controlled by a computer module behind the dash. The only possibility I can think of is possibly replacing the GT PP gauge "cluster" with an Ecoboost unit. Has anyone else looked into this? Or know of other solutions out there?

The quick answer is no, the EB guage won't work.

Nothing on it yet though. i think it would be awesome.

Didn't really want to do that anyway, the cost would probably be outrageous. I'm hoping for an aftermarket solution

Oh sorry for the repeat post, I did some google searching before posting and didn't come up with anything. Hopefully someone will come up with a solution soon!

Hopefully the aftermarket will catch on, and make a mechanical boost gauge that matches the PP gauges, and works with my color.

If sure they will, but based on the design of the factory gauges I doubt they'll be mechanical. Probably electronic to be plug and play with the factory system and My Color. Unfortunately, that means they;ll probably be expensive

Can you use the digital one on the center screen?

The question is why not?

If it reads vacuum, it should be able to read boost from the same line.

Am I missing something? :shrug:

If it was mechanical you would be right vacuum=vacuum and boost=boost. But since it's electric, you can't use the same signal for 2 different ranges of indication. I'll break it down for you, using examples, these ARE NOT direct readings I've taken from the car. Most gauges uses a 0-5vdc signal.
Say .5vdc reads 24 in/hg and 4.5vdc reads 0 in/hg on your PP vacuum gauge. You swap just the gauge to an EB PP, that .5vdc signal would read 12in/hg and the 4.5vdc would read 10psi, even though your car is still pulling 24 in/hg and 0in/hg respectively.
You will probably need (at least) the EB PP vacuum/boost gauge sending unit (to recalibrate the signal) and possibly a computer flash if it converts or translates that signal at all.
Hope this helps your understanding.

Normally you are 100% correct. But, what if the vac gauge is only calibrated for, say 0-2.5 v input? Would be easier and streamline parts.

I guess looking at ford parts.com would answer if sender is the same or not.

I do think all gauges are fed by the computer now though. Which means a gauge and a reflash is all that should be needed.

Lots of unanswered questions to even guess what's right atm.

The way it was explained to me is that the EB gauge is dependent on the EB's MAP sensor which would make it incompatible with the GT's MAF sensor. :shrug:
