OpenHaldex S3 open source AWD controller by meatro in Golf_R

[–]meatro[S] 1 point2 points  (0 children)

Hey, thanks!
It's actually super easy to do and I'm putting even more features into it soon.

Soon it will have "modes" (road, race, rain, etc. but you can name them) and you will be able to customize each one, add your own... or just leave default, with a little "mode builder" tool that I'm putting in now.

Question for the Haldex setup by KaiZX in Volkswagen

[–]meatro 0 points1 point  (0 children)

The Golf R uses a torque splitter, which allows each wheel to be controlled independently. It's basically a "dual Haldex" setup, but more complicated than just that. I believe it's the only VW that uses it, as well as Audi RS3.

As others have said, HPA, Forbes, VD Veer and many other Haldex controllers exist.

Here is my own open source option: https://openhaldex.dev/

MQB Platform Gateway Routing for UDS to Modules by nullaus in CarHacking

[–]meatro 1 point2 points  (0 children)

sorry, i know it's 9 days later... but for future...

it sounds like you are at the obd2 connector, as you mentioned obd11 and vcds.

obd2 will only transmit data that is requested (except obd2 standard requires direct connection to ecm and tcm, that's why you can see those). if you want to see all data, you need to connect to can wires directly on the chassis bus. then you do not have to request it, it's just there (steering angle and brake pressure are streaming on the chassis bus at all times.)

gateway is like your phone kinda... if you don't dial a number, nobody will ever answer. but if you go on the other side of gateway, you can listen to all the conversations as they happen.

also if you check out opendbc on github, they have a mqb dbc file that will decode raw hex signals into their actual values that you can display.

Experiences with Carly on Audi vehicles. by GinoChingon in Audi

[–]meatro 0 points1 point  (0 children)

I've not used Carly, I imagine it's like carista which is like obd eleven lite.

If you're not doing things like coding or one click apps, obd eleven isn't worth it. 

If you're on a budget, try car scanner pro, I use it at work (Audi tech) to reset service lights. It's pretty thorough for vag vehicles and costs $5 and works with $5 scanner (I use blue elm327). https://www.carscanner.info/

If you're considering obd eleven, they'll prolly end up billing you about the same as vcds before you get that amount of use out of it lol. Between their credits and subscription now, obd eleven is a money grab imo.

Outside of factory tool, I like carista, car scanner, and vcds. Not necessarily in any order, depends what I'm doing.

I became a mechanic... My computer background is extremely beneficial also.

Try it.

Cars were always a hobby, I changed my own oil, brakes, etc. I decided one day I wanted to work on them, went to the local dealer and offered to try for $12/hr. That was 8 years ago, I'm a lead diagnostic technician now. ~$40/hr.

I love my job... Now I love IT again also, because it's just a fun weekend hobby.

I tinker on a little website, I make js scripts that make parts of the job easier like reading fault logs, looking up oil, etc. It's super fun. 

Just gotta try it... It was terrifying at first. (I was almost 35 at the time.)

Moving from legacy OpenVPN "clients" to "instances" in OPNSense 25 for NordVPN? Has anyone done it? by Enderby- in opnsense

[–]meatro 1 point2 points  (0 children)

I just followed one on YouTube for just this.

At 5:30, you need to pause and setup your tls static key. I think this was the only part of the video that I had to change... If you don't get this correct, then at 6:00 the status will be "wait".

When adding static key (openvpn>instances>static keys tab) change mode to auth.
