Just crossed the 190K mile mark this week. Still runs like a top

Congrats on hitting 190k! Our have been pretty much stalled at 148k since our X had been relegated to being our spare 3rd car duty.

Nice looking e53!
What does the 'modified temp gauge buffer' do for you?
Are you able to set the temp for the over temp alarm or is it a predetermined bit?

The modified temp gauge is simply taking out the ridiculous 40C (104F) buffer in our coolant temp gauges. The gauge will read in the straight up position anywhere from 75C to 115C. Not acceptable in my opinion so I just change the hex code of the gauge EEPROM with PA Soft 1.4 to have a more suitable buffer of 10C from 85C to 95C. You will find and have to change the code in 2 places as listed below. This is coding for the M54B30 engine and is spot on. The 8 cylinder version of engines temperatures seem to want a little more buffering and maybe take those to a 20C buffer

The addresses for the code string are:

0x0F0 rolling into 0x100
0x290 rolling into 0x02A0

My original hex code starting at:
0F 62 32 CB 4B CB 73 38 78 6A 7D FF
Changed to:
0F 62 3C CB 55 CB 5F 38 6E 6A 73 FF

This brought my buffer to 10C (85C-95C) instead of the ridiculous 40C (75C-115C) and lowered my red zone from 125C to 115C so I have some early warning to shut it down without killing the engine. It also brought my blue zone from 50C to 60C so I would have been alerted about my soft fail thermostat easier.

I programmed the EEPROM and took it for a ride with Torque Pro running and it is right on the money. I can not test the red zone but it can only be spot on as well.

For anyone wanting to change the buffer on the stock X5 E53 you need PA Soft 1.4 software. Here are step-by-step instructions with PA Soft 1.4
1) Click on IKE.
2) Click "Read EEPROM"
3) Hex editor functions are in the lower left hand corner. Click the floppy disk icon to save the factory loaded file onto your desktop as backup.
4) Make revisions from "factory" values to "revised" values shown above: Find the corresponding offset and move the cursor over the bytes to be revised. You can use arrow keys to move the cursor as well.
5) Click "Write EEPROM." Your cluster will flash and beep several times after completion -- and like magic, your gauge will now reflect more accurately what's happening under the hood.
6) You will need to reset you time and date after the cluster EEPROM has been flashed



To change the over temp gong alert you just need NCS Expert and NCS Dummy to make a new parameter to select from the LCM trace file. This should work on all high clusters. I have never verified as I have never got to 115C but it should all be straight forward.

I looked at my trace file for my C22 LCM and found the following.

KUEHLMITTELTEMP = melden (reported)
(CHECK CONTROL FOR COOLANT TEMPERATURE)

KUEHLMITTELUEBERTEMP_CAN = activ
(CAN-BUS COOLANT OVERHEATING)

MOTOR_UEBERTEMP = 125_grad_celsius - 125 c (257 f)
with an option of 130_grad_celsius - 130 C (266 f)
(ENGINE OVERHEATING [TEMPERATURE_C=DATA])

So if MOTOR_UEBERTEMP are the alarm thresholds:

I will add another parameter to MOTOR_UEBERTEMP:

115_grad_celsius - 115 c (239 f)

Open up the LCM.Cxx file with NCS Dummy without loading any FSW_PSW files, go down to MOTOR_UEBERTEMP, right click it, and click "add parameter". Name it whatever you want, and under data put the hex value of the temp alarm you want. Then click on module -> update module.

You will be able to select that new parameter when coding the LCM now.

Nice work Boost! I would definitely like to have this mod!
