OBDLink Custom PIDs

Using the latest version of the OBDLink MX ap it is now possible to enter Unit values.
If you have Metric selected in the settings then you can enter a "C" for a Metric Unit reading and it will show in the Trans Temp.
The same with pressures etc.

Aternator Current Clamp Amps
Min Value: 0
Max Value: 200
Header: 7E0
Mode: 22
PID: D113
Equation: ((A*256)+B)/20 If you are getting figures like 500 amps then change equation to ((A*256)+B)/200

This gives a % reading of the battery state of charge for the MAIN battery only.

Hi mate thanks for putting these up. I’ve got a 2017 ranger and I can’t get the tyre pressure to work. Was there anything additional you have done ?

Are you using an OBDLink MX (Black Bluetooth) dongle?

Nothing else, all I can suggest is to check you typing, something as simple as a space after a number/letter and it will fail

The only thing missing in the pic is the name & category, not important, call it what ever you want.

If yours is like the pic I have no idea why it doesn't work.

I was just playing around with this tonight and was wondering if the reading correspond with the actual corner of the ute or the specific wheel. I ask this because as we rotate the Tyres the reading won't really be reflecting on which corner they are at?

The PID numbers are different and each number corresponds to an individual wheel and position.

This is why you will need to re train the wheels when you rotate them.

Ah ha. Thanks for that. Looks like I'll need to get a training device.

I actually hadn't looked though all of them. I just transferred the one I use in Tourque to run on OBDLink.

The tyre temp has gone cranky, reads 215c.

Never had issues until I installed a tune, maybe just a coincidence.

Mine starts at 215 and after 5 minutes or so reads normally. Not sure why but I live with.

Mine also reads 215 for about 5-10mins then appears to read normal

Thanks for putting these up and doing all the work.
so a couple of questions.
1. Do the maximum values relating to temp also relate to alarms? If so then is 200 too high for auto transmission temp?
2. What is a healthy and an unhealthy temp for the intercooler?

Re: OBDLink Custom PIDs

I would think the vehicle temp alarm would be okay, but you could set the maximum to what ever you like.

I have heard of temps reaching 107 so maybe set at 105.

I don't know at what temp the vehicle alarm goes off.

Regarding intercooler temps I would think the colder the better, but I may be wrong.

I'm also not sure what an acceptable Intercooler Temperature maximum would be. I've heard that at 80 degrees limp mode is triggered. I've had mine at 84 degrees up a very long steep climb without any problem. It would be good to know the upper limit. Your feedback would be mose appreciated.

The temps you are reading here are engine coolant temps.
There is no way of controlling Intercooler temps to my knowledge, other than fitting a better Intercooler.

Thanks for your response. I'm not trying to control the Intercooler Temp, just trying to understand where the upper limit may be. I've included a picture of my gauges, where everything looks OK. The Everest Forum has someone declaring that anything over 80 degrees will trip limp mode.

I do not recall reading what the upper limit is in any documentation over the last 3 years.

Hi. I'm using an OBDlink MX on a 2015 Everest viewing on an Iphone/pad. I created 2 Pids based on your settings and those of RossPat for the transmission temperature and they both display 0c when driving?

Run "Test" from the Pid creation screen and it comes back "No data received"

Any suggestions please

Automatic Transmission Temperature
Min Value: 0
Max Value: 200
Header: 7E1
Mode: 22
PID: 1E1C
Equation: ((A*256)+B)*1/16 and alternative ((A*256)+B)*10/160

I had incorrect data in this thread and have edited to reflect correct data,

I am using Equation: ((A*256)+B)*1/16 for transmission temp.

Hi. Illegal formula with the °C so I deleted it but I still get no data received on test.
Starting to wonder if Ford didn't connect something when they did the trans oil leak fix because they stuffed up the Adblue connection at the time

This is mine and it works well, so maybe they did do something at service.

From the thread info above I used the Ford one, see below, and it worked on mine, auto trans.

0 200 7E1 22 1E1C ((A*256)+B)*5/72-17 ℃
I tried this compared to the other one and both work on OBD Link app but yours reads 17 degrees lower by the formula
