Default Coding Fun

I recently bought a Launch X431 Pros Mini tool off Amazon because I installed a ducktail spoiler on my car, and needed to code the car to not throw the spoiler failure error at 75mph. Since this tool is basically a mini PIWIS it can also do other coding-type activities. I paid $890 shipped for it.

Cayenne guys have been doing this for a while which is where I got the settings for a couple things from
https://rennlist.com/forums/cayenne-...ispreloading=1

From what I know Launch, Autel, and Matco Maximus scanners have this ability.

If anyone around LI wants something coded, shoot me a PM. It only takes a few minutes to do.

Things I have changed

1. Removed spoiler error for ducktail spoiler

2. Made water temperature gauge read accurately like the GT cars (Car actually runs between 180-220 degrees not 194 like the gauge shows from factory)
https://rennlist.com/forums/991/1283...t-the-fix.html (thanks Asellus)

3. Windows open with keyfob

3. Windows and sunroof close with keyfob

4. "Teardrop" wipe feature - "After the wipers stop, it will wait 10 seconds and wipe 1 more time to get rid of the 'teardrops'."

5. Adaptive brake lights that flash in fast emergency braking

I did a little write-up on it here.

The whole process is very quick, like 1-2 seconds once you click go. WAY faster than flashing an ECU with a Cobb or the like which can take like 30 min the first time.

4. While using windshield sprayers... "After the wipers stop, it will wait 10 seconds and wipe 1 more time to get rid of the 'teardrops'."

5. Adaptive/Emergency brake lights, I have mine setup as it would have come OEM which is 1 second when the default parameters are hit.

I tinkered with this coding and it's possible, but it has many drawbacks. There's a post or two floating around somewhere but the tl;dr is that the lights "stick" if you toggle them.

I think setting "Coding Value: External lighting installed daytime running lights" from True to False in the Front End Body Control Module would do it but would need to be tested.

I'll see if I can try later on my 991.1, worth a shot, but will probably get same errors as you.

Did you try these at all?

In Instrument Cluster
1. Warning configuration: Warnings BCM_ Hinten Warning daytime running lights defective (57)
2. Further coding: General configuration external light daytime running lights

In PCM

"Additional equipment part 1 daytime running lights"

Also one in BCM but I assume that's for tail lights

I thought #5 was standard on all Porsches - brake lights flash in emergency braking
