2015 Explorer Sport
Hello,
New to the forum. Have a 2015 Explorer Sport with 3.5 Ecoboost. I am trying to add a boost gauge and an air/fuel meter. I have added these to older turbo diesels and older K cars without problems, but am having problems with this newer vehicle. I know I have everything wired and plumbed on manifold correctly for the boost gauge, but the gauge reads random numbers, doesn't matter if it is under boost or vacuum. For the air/fuel meter, I have tried 3 of 5 wires on the O2 sensor(pretty sure which 2 are not used) and it will not read correctly. Just flashes '10' and meters to the right full green all the time. I have looked on line for color codes to which wire to tap into, red, white, black, yellow, or gray. Not sure who makes this brand with these colors. The age of the sensor/heat has removed any markings. Am I missing something? Try a 4th wire?

Thank you.

You can read all of this via the PIDs. Those and a TON more...

I can never understand why people still use manual boost gauges anymore on these vehicles. The work required to plumb a boost reference (or a Hobbs switch) seems like the same, if not more, work than tapping into what is already available digitally. Not to mention, you give yourself so many more options when reading the PIDs from the OBDII port. I think last time I ran a scan on what can be read, there were almost 700 parameters. Add to that the ability to create your own gauges reading whatever you'd like by creating calculations and equations based on other parameters within the apps such as Boost Air Density, Manifold Air Density, etc...

Anyway, I know they are "options" but the juice wouldn't be worth the squeeze for me. Torque Pro is one app, but there are more available...Forscan (and Forscan Lite) is one that you can also create custom dash layouts. I went a really pricey route for sure, but it can be done cheaper...
 






For boost gauge, can you tap into the blow off/bypass valve?
Those usually see boost/vacuum (I'm not 100% sure on the Ex though).

For AFR, can you probe the wires with a multimeter to see voltage? At least one wire should be providing a variable voltage (usually between 0V and 5V) back to the ECU. I'm not sure if these O2 sensors have separate wide band and narrow band signals.

I agree that an inexpensive OBDII reader and Torque Pro app would provide the info and then some. I actually have those and used them in the past for fun on my Explorer (mainly used for diagnostic on my wife's CX9). I believe you can record as well with the Torque Pro app.

The factory BOV on this platform are electronically controlled...if you're looking for the best place to reference boost/vacuum...it's here:

 






Thank you for your replies. I will have to investigate this. The apps for vehicles are new to me. I still think old school with the old K cars and turbo diesels.

do you have custom PID in Torque Pro? For Ecoboost Engine?

You can import the FORD specific PIDs. In torque, in the PID manager screen click the menu icon and select import "predefined" set and select Ford/Mazda/Lincoln. This will get you all the PIDs that work with Ecoboost and most new fords.

this maybe only work for 2011-2015 in 2017 many PID not working
