launch x431 v

I'm pretty pleased with the Launch X431 V+ diagnostic scanner so far. Works great as a code reader (it knows I've pulled the fuse from the sound generator), and should do all the maintenance resets and other normal DIY stuff easily.

And the coding function appears to be fairly complete and robust. Here's the list so far:

A-S/S button saves last state
Gauge backlighting always on (white face hack)
Disabled seatbelt warnings
Remapped coolant temp gauge accuracy
Comfort blinkers to 4
Windows up/down with key fob
Change side markers to indicators only*
Activated teardrop wiper (not tested yet, don't want to spray all over the car).
Change/disable the auto-headlight washing after 10 washer uses

I've failed (so far) on a couple things, which means I either haven't found the true spot to change, or haven't found some other required spot (some changes need to be made in multiple locations).

Change spoiler deploy speed
Change Auto headlight sensitivity
~~Change side markers to indicators only~~*

*Note - I thought I'd failed on this one, but it appears to have working now, the front corner lights are now ONLY indicators, they do not illuminate with the parking or main lights. Not 100% sure what change that I made did that, so I hope I continue to like it that way as I didn't make notes of any of the settings that didn't seem to work...

Still to come:

Enable NAV display in MFI (need LVDS cable)

Other things I'm thinking of that I'm not yet sure if they can be done:

Auto parking brake engage
Re-map tail light function to EU/RoW config
Enable PDK Coasting mode while A-S/S is off
Don't unlock all doors when opening trunk/rear lid via fob or proximity sensors

About the instrument lighting:

I first did the normal "white gauge face hack" to turn on the gauge backlighting. But I found a different way, too. There is a setting to add the tail lights to the DRLs. This is sometimes known as "Scandinavian DRLs" as those countries require the tail lights to be on all the time as well as the DRLs. I did this DRL change to my Audi, as it can be gray and foggy around here in winter and having the tail lights on then is desirable. So I found and tried it on the 718 this afternoon. Works fine, adds the tail lights, front side markers, parking lights, and the gauges w/needles!

This may not be for everyone, but if you don't mind having the tail lights on in the daytime, it totally takes care of the gauge illumination issue.

Front-End Electronics > Exterior lighting > DRL with marker light = Yes

Something I noticed to research further - There are some spoiler params that appear to indicate possible visual spoiler notification, either in MFI or console button light. First attempt did nothing, but I'm going to give that some more research later.

Anyway, so far, so good. Even if I don't get any of the other stuff to work, what I've done so far is great.
