I decided to go this route so I could program and calibrate on my Porsche while using my PIWIS Programmer. This can be used for many good purposes to keep your battery from not going dead also. Credit goes out to the guys at 6speedonline for the original article on how to build this amazing power supply for under a hundred bucks if you already have all the soldering equipment. I will post all the items here.

I was quoted 6k at the dealer to replace the TCU on my wife's Macan i said a quick "NOPE" so now i have went down the deep rabbit hole of learning to get this appropriately replaced and programmed but if it is just the wiring harness then no need for reprogramming. I'll be building this for sure and updating once i get the time to get started on everything.

If it were a Panamera I have a tcu just sitting in the garage I’d give you. Good luck on your voyage. It’s a pretty simple process if you have your own piwis. Let me know if you need one. A good friend of mine sells them very reasonably and will get it set up and configured properly for you.

Hi, I've build this device as well, based on that 6speedonline and it worked fine when I used it first time, but soon after (15 min coding) the battery indicator light up and it was looking like the power supply could not keep up with PIWIS. Have you come across this issue? I did not make a hole to adjust that controller, that is one nice idea. Did you have to make multiple adjustments on that, that you figured you'll need a quick access like that? Thank you for the video and tips - priceless!

I wish you had shown *how* you connected the power supply to the battery... And what was the cable you connected the last... The negative electrode? I read that one is not supposed to connect the wires from the power supply directly to the battery: _"The power supply must be connected to the terminals in the engine compartment. DO NOT connect directly to the vehicle battery."_ I am completely untouched by this stuff, and I plan to do some flashing in a couple of weeks. (Not a Porsche though.) Cheers

Hey John. Thanks for the video! I'm a little familiar with electronics, being involved with ham radio. Anyway, I just picked up a icarsoft por2. Do you use anything like this for your Panamera?
@TomorrowsTek
@TomorrowsTek Рік тому
Yea I started off with the por. I used it to reset my oil light. Its good for checking basic obd alarms. If you want a video I can cook one up for you.

@@TomorrowsTek next time you need to use it, it might be something of interest to other people, as well. I've got to check engine light, that I thought was associated with my gas cap warning. Replace the gas cap, still have the engine light.

@@thomashelm6931 not a problem I have a few alarms on mine right now. We have company over today, but when they leave tomorrow, I'll pull it out and do a little guide on it. We will see if we can help you clear yours.

@@TomorrowsTek fantastic! Appreciate it very much! I don't know how radically different our testing devices could be, not much, I would imagine. I believe there is a menu selection for clear all faults. I've tried to do that, it pauses and says that it can't clear all of them. My description may be confusing but any content regarding clearing faults would be great. I've gone down the rabbit hole, scrolling through about every menu and sub menu there is. Maybe I just need to take it to a mechanic and have them deal with it. But, like you, I try to do it myself before getting to that point. Thanks again!

Hi John, hope you can help. I bought the same unit and tried to reproduce all the steps from your video. I ended up having the led light color red, so I decided to remove the resistor and the soldering on the DC-2173 board. After doing so the led turned green and I could adjust the unit to 14.20 V. Do you see any problem with this setup? Thanks
@TomorrowsTek
@TomorrowsTek 4 місяці тому
As long as your able to adjust. I don't see anything wrong with that. Great work
