PA SOFT: How to reprogram our temp gauge

[JupiterBMW]

BTW, Terra, you're always a huge driving force in these amazing electronic DIY/retro/fixes... Hats off to you man!

ZHP clusters come with newer software that deals with that curve a little differently, so you'll want to follow the instructions in the post below

In other words, what's posted from e46 fanatics is for pre facelift cars?

Do you think I should grab your post and add it to the end of the first post? We want to be sure that ZHP people code their cars correctly, after all.

Thanks Terra :D

Sub'd. Thanks Terra!

Wow, I didn't realize how little information the coolant temperature indicator provides.
Does the car provide any type of audible warning when faced with imminent overheating? I was under the impression it did, but how would I know?

Thanks for bringing this to everyone's attention!

I tried this yesterday and my values on the originally mentioned lines didn't match up at all. I'll check out the link provided for facelift cars and try that today to see if the values match up. If so, I'll be doing this today.

Thanks so much for this info... this will be extremely valuable when on track!

Be sure to report back on the values and the gauge behavior after!

Not really. Look up 'coolant snitch', which someone developed for that reason.

I tried it today after reading the link provided by Terra. This works like a charm!
It's going to take quite a while to get used to the coolant temp gauge staying on the cold side for such a long time while warming up as it is showing the correct temps now. When you shut the car off (in the winter), very shortly, the needle moves down quite a bit, where before it would stay in the middle after starting the car back up because of that wide temperature range it previously had.

It is most definitely a worthwhile thing to do. I just hope I won't freak out when it starts to rise towards the right-side when I'm on the track in the summer!

^^^ as someone in the original thread mentioned that can be an advantage as we are less likely to floor it if our temp gauges are still on their way to the middle mark.

glad to hear it worked. I am going to attempt this next week.
