Boost gauges

[ControlNode]

The information is there. All modern vehicles use those to factor in engine and cooling settings. We are attempting to unlock where we find those values and how to relay those to the gauges.

I don't think there is any actual information. As I understand it, that ICM looks at other values on the HS CAN (engine rpm, engine coolant temp and even engine load should be among them) and calculates the oil temp and pressure from that. My thought is that Ford had those sensors on a test engine and trained the ICM to reproduce those readings when giving various inputs on the actually available values. If Kevin's test confirms it functions I plan to get the 2016 -2018 Focus ST gauge pod. I'm hoping that I can get 2 broken Ranger clusters with the tach and speedo so I can get 3 blue needles from the fuel and engine temp gauges to move to the ST gauge pod so they match.

I had a Focus ST with that gauge pod on top of the dash. The gauges are so small with such a limited sweep they are pretty much useless, especially the boost gauge.

Who said the RS even has those sensors? I know it doesn't have oil temp.

Edit: And a quick scan through section 20 of the RS's Wiring Diagrams I only see a simple oil pressure switch (low/normal).

And I got notice that my Ranger FSM and wiring diagrams should be here tomorrow.

I was talking about the fact that the Ranger does not have these sensors to give the readouts for the gauges. It only has switches for idiot lights.

And I'm saying the RS and ST also lacks those sensors, and yet has the read outs.

What are they using to get those numbers without sensors?? Magic?

Algorithmic interpolation.

Algorithmic interpolation.

From what are they interpolating? Temp is temp, pressure is pressure, how accurate can interpolation be?

Accurate enough to create a PID to run a dummy gauge, because that's typically all they are used for. The information isn't needed for the engine management, it's purely there to move a gauge back and forth to appease the driver.

I'm just curious what values they are using in their interpolation to get oil pressure and temp. Also why hasn't anyone found the PID loops so we can display them, phony numbers or not

I can't speak for this platform but I know typically with Ford the pressure is simply a switch. Temperature is usually inferred from another temperature sensor. So you may have a vehicle with coolant temperature gauge with no actual sensor, in most cases the coolant temperature is inferred from the cylinder head temperature sensor.

From the RS Service the ICM monitors these messages: (I'm guessing to take that with a grain of salt since I'm not seeing MAP message for the boost gauge)

Message	Originating Module
Door Status	BCM
Engine oil level warning	PCM
Engine oil temperature	PCM - for engine oil temperature gauge
Engine RPM	PCM
Oil pressure warning	PCM - for oil pressure gauge
Power mode	one file shows BCM and the other shows PCM and that it's used for boost gauge

Anyone seen this? Could run Torque Pro on the main screen. Also seems pretty neat to get Carplay type functionality without needing a phone. The price is pretty steep though, so not something I think I would do, but might be a neat solution to get some OBD2 driven gauges on the main screen.

Not sure about the Ranger but the water temperature gauge was not a gauge on my Focus ST, it was a two position indicator. That is once the water temp was slightly over 100F it go to the mid point and when it was hot it would go to the H on the gauge. It was damped enough so that the needle would move slowly so you would think it was tracking the temperature. But if you compared it to the water temp in the engineering display you would see the difference. I suspected that the water temp gauge in the day of my Mustang was the same but comparing it to the engineering mode temp they tracked reasonably well.

Not sure what that box is for. Looks like if you had a car that only had CarPlay you can use it to run Android Auto through CarPlay.

Anyway, I had an app that I downloaded from XDA-developers called OBD2AA. It was a plug-in for Torque Pro that let you display Torque Pro data on the Sync screen. It required you run Android Auto in developer mode and it was tedious to setup the gauges you wanted to see but it did work. It required you to launch Torque Pro on your phone and wait for it to connect and be up and running. Then plug in you phone to Sync and wait for AA to connect and display on the screen then you would launch OBD2AA. It took some time once launched before it would actually display data.

The guy that developed it pulled down off XDA-developers so he could concentrate on his wireless AA solution.

I've used that, but it has not really worked with the latest versions of AA on Android 12 for me. I had a nice custom layout for my RS.
