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

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)

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'm chicken to do things like this. I'm worried I'll fk things up ?:P) Would love to have the water temp gauge read correctly!

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.

Nice! I need 2 & 3, not sure what 4 is. 5 might lead to a ticket where I live, lol.

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.

Cool stuff. Is there way to disable Day Time Running Light on 991.1 with X431?

asellus

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.

this throws oodles of errors on my PDLS+ 991.2

I always wanted disable DRL but now I better give up on that.

AdamSanta85

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

AdamSanta85

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

It was disabled on my car (2012).
