I was using a Bluetooth ODBII adapter and torque on my phone to get the oil temperature of my 328. I don't like having to manually connect each time, so i decided to code my MPG Gauge to display the Oil temp. It took me some searching to figure it out, so here is a guide for some assistance.

1. You must have BMW EDIABAS 7.3.0 installed and have a K+DKAN Cable

2. You can download the full BMW tools installer here.

blob:https://mega.nz/280dc1f8-8292-4e6b-b22f-88e917370991

3. Extract the zip folder, this is what you will get. Run the application and go through the install wizard. I installed it at the root of the C drive.



4. Once the install is done, these icons should be on your desktop.



5. Plug in your K+DCAN into your computer, if you are on Windows 10 it should be able to find the driver automatically. Open up device manager, expand Ports. You should see your cable there.



6. Right click your device under Ports and you should see "Advanced" which will bring you to this screen



7. You want to choose COM1 and set the Latency Timer to 1

8. You should be able to connect to your car and open INPA, if there is a green circle next to battery, and it says ON you are connected



9. Download Perfekt Toolbox

http://toolbox.mrperfekt.com/downloa...ektToolbox.zip

10. Open Perfekt Toolbox



11. Expand Instrument Cluster



12. Choose consumption/oil temp. Click Read from ECU. Take a backup! THis can be done by clicking "Save to PTG-file)



13. You will want to select Oil Temp under "Gauge Function". Fill in the below numbers, it only allowed me to enter them correctly from right to left.

These numbers will give you a temperature range from 50C (122F) to 150C(302F). Make sure the motor steps are filled out as well.



14. Write to ECU. If all goes well you should be able to test if its working. Set the test to 100C this is will bring the needle to the middle of the MPG guage. This is equivalent of 212F and roughly operating temperature.




Here is a picture of my car at operating temp.



If there is interest, i can post install steps for the BMW tools with pictures.

I am going to take the gauge cluster out and put in 335i gauge faces which have the engine temp instead of MPG. I will be doing a white led conversion as well.

Wow, this post is about to explode! Ppl have been looking for this for a very long time! What is perfekt toolbox? Can you post with Bmw tools? Well done! How did you figure this out?

[nsjames]

it's always been possible to recode this using NCS.

the perfekt toolbos software does make it incredibly easy.

bmw tools can be found at the bimmer geeks website under the download section.


and just to top this all off, I recently bought and shipped a 7K rpm cluster to a guy that's going to print me OE style gauge faces to properly put the oil temp scale in the 7K RPM tacho.

I will post information after we're done with the R&D, but soon it will be possible to just get new gauge face and have a stock looking 7K RPM tach with an oil temp.

I have some prior coding experience, but as far as this specific mod it was all info that was out there. I just had to gather bits and pieces from different sites, i went this route because it was much more straight forward than NCS Expert. I revised the post to include BMW tools instructions.

I did this over the summer except I put in a 335i cluster face.


Delete mikes standard tools and use the bimmer geeks package.

[mecheng77]

To be clear, is this for water temp even though
The box says oil temp? Do 328i have an oil temp sensor?

I have the bimmer geeks install on my other laptop, but tried Mikes BMW tools for this one. Out of curiosity, whats the difference between the two?

I think this is for oil temp as stated. I looked into something similar in the past and was told by other forum members something to the effect that the water temp signal isnt available on the connection the the cluster (not sure if this applies to all E90 models). I'll see if I dig up the thread with this info.

Here's a direct quote from another forum member when I inquired about water temp:

This isn't possible without a piggy back device.

The only reason why oil temp can be displayed is because both oil temp and mpg are stock options on the same piece of hardware and are built in options within the software.

Water temp was never included as an option and so wasn't programmed into the software.

Either way, I find it interesting that its so hard to get the water temp to be constantly displayed anywhere in the car despite the fact that its easily accessed in the "secret menu" of the cluster...

On a side note, am I correct in assuming that this would also work on a diesel E90?

I understand what the OP wrote. If you read the instructions carefully, he specifically states "You will want to select Oil Temp under "Gauge Function". Furthermore, the Perfeckt Toolbox doesnt only seems to let you choose either consumption or oil temp. Seems to me he's using oil temp as a substitute for water temp.

Either way, hopefully OP chimes in a little later and clarifies this.

I wasn't quite sure at first if it was coolant or oil temp, due to reading different things online. I watched it on my drive into work this morning, it warms up much slower than coolant temp would rise on my torque app. This leads me to believe its displaying oil temp.

no, it's for oil temp.

water temp isn't what you want to be monitoring anyhow.
oil temp is monitored as part of the oil level sensor.

Would love to do this if I can get hold of a tacho face with the oil temp markings - ebay, here I come!

I bought a set on ebay.

Pretty cool! Drives me nuts not having the oil temp gauge

How do they look, can you post a pic?

Are they overlaid on the stock gauge or do you remove stock to install these?

Ah okay, I thought you stumbled upon solving the Oak Island Mystery. As others have stated, nobody has been able to figure out how to display the water temp permanently without bruising your finger, in my case needing the number 27 to unlock the hidden Mike Tyson Punch Out menu

Nonetheless, oil temp is better than the stupid instantaneous fuel economy. Who really cares about the instantaneous fuel economy, average is more relevant and both can be accessed in the BC. I never understood why so many BMWs have it. Thanks for posting this, I will try it out.

I am still waiting to receive them, i will post a picture once i have them installed. These go over the stock ones.

What an odd thread.

Rocky, how were you using OBDII to get oil temperature?
I pulled a 2000 lb trailer across the country last year and I could not for the life of me find the correct oil temp PID for Torque to use. I had a load of telemetry during the trip but no digital oil temp. (I used NCS to recode my cluster.)

[Phyrexia]

Also, the reason there's no coolant display temp in our cars is because the system regulates its own temperature very well and the temp changes more with driving conditions than with ambient temperature changes. For example, pulling up the hill traveling East leaving Albuquerque, my oil temp hit 125 or 30 C, but my coolant temp stayed steady at about 215F during the pull.

Carly even gets you oil temp via OBDII. Confused
