Temp gauge re-code

80stech · #1 12-20-2018, 02:24 PM

So I was inspired by a "how to" BMWscanner 1.4 link that Overboost provided in a previous thread to try and recode my temp guage. Mucked around a bit last night and wasn't succesful (most of the info is for E46, E39 etc.) but sure looks do-able. I think I just need to use NCS expert dummy or try out the checksum fixer in BMWscanner. Has anyone done this on an E53?

I think Crowz previously posted a how to.

Yeah, that's a good document. I wrote it

Hello wpoll, may I ask what temp range you went with for your gauge on your 3.0d?
What was your original hex values?
And what did you change it to?
Have you considered making your speedo more accurate by changing that too?

I sent the modified C22 module .TRC file with my added parameter drop dead warning at 115C that matched my final point in my gauge to my LCM. So if I (or my significant other

) were to miss it and the message and gong were to ever come on I know I can cut the engine safely without permanent damage. The original 125C would have been a little on the "well done" side for me...

You can ask...

I haven't touched it. I don't worry about the temp as much on the 3.0d. The biggest issue with the 3.0d is running too cold, not too hot - and too cold is easily seen on the factory gauge settings.

But if I was to goof with it, I'd go with something similar to the M54 values as in this thread, just for slightly more clarity on the normal variations when running. And I'd set the over temp alarm at 110DegC.

Since replacing my thermostat a while back, I occasionally monitor the operating temp via the menu #7 and it sits bang on 88DegC. most of the time, climbing as high as 95DegC. when towing a trailer with 2-3cubeM of firewood up steep hills. Never seen it higher than that...

Fair enough;
I was thinking along similar lines that it’d be unnecessary;

But the weather reached over 40 degrees Celsius here today,
and I suspect my X5 was running hotter than normal ,
but my gauge never moved past dead centre, and I would prefer to know easily if my motor was running a bit hot as it sounded different, a higher pitch that disappeared when it cooled down.

I think I may also change my speedo to show true speed if I can figure that out...

How can I help? Did you get my how to? Grab some shots of your EEPROM and I'll see if we can find the code in there. Thinking it should be the same lines...

When I try to write BMW scanner comes up with 5 errors and eeprom doesn't change. I'll try it again but from what I have read either a person has to change to exactly the right values so that checksum remains intact or recalculate the checksum, which supposedly is doable in BMW scanner? Looks like you guys didn't have the checksum issue?
