This commercial tools are based on work from this open forum. Isn't it strange all tools came on marked shortly after this project was visible here. Now you blame us that we don't develop so fast like the guys which get 4600 $ about their full set.

I think VTL and I did this just for our own cars, we both drive p2 cars and we like our p2 cars. This is our interest.

A few posts above i posted the arduino software to read and write the CEM -MY2004.
A few posts later i posted the tool to change car config.
I have a nearly ready solution to write CEMs config at CEMs -MY2004 by DICE.

I have a UDS reader to read all CEM MY2006- by dice.
I also can support a reader which reads all CEMs from MY2005 by 6 byte pincode.

Also CEM can be read by teensy it would be an easy addon. But i think most users seem to like the easy uncomplicated way here..

The remote fob is stored in the UEM, you need a new fob with codes on package or a used UEM from same MY with used fobs. The transponders are stored in CEM.

How about releasing an open source software that others can add to and improve?

Cmd line sucks. App to run an app.
Make a GUI. First thing you do in C++ class is build a GUI calculator..
Come on, Man. High school level shit.

If you released a comparable (open source) freeware, the other people wouldn't be able to profit off your contributions..
But since you refuse to do the work of compiling the information into an easy to use GUI, You Lose.

Your greed, and self-centered perspective, makes others wealthy.

Ironic, innit.


All this hard work - greed and shortsightedness bites you in the ass.
You don't think in terms of other's perspectives.

"Why would I do anything without money"
Because others will finish what you started and make the money, if you arent willing to finish what you started.
"Half-ass" much?

You really expect people to want to spend hours of their life digging through 200 pages of childish bickering about "If you have to ask, you shouldnt try" and "its out there", and "no you're wrong". It is complete bullshit crap and a waste of my short life because you can't be concise, agree, work together, or complete a project. 200 pages of shit, and not really much to show for it besides negativity.
Social skills of Kindergarten.

Why don't you release a compiled tool with all the functionality and features you have discovered into an easy to use program?

You are Literally part of the problem, Luke.
You failed to (Publicly, in a digestible way) solve the issue you set out to identify.

Just Do It. Excuses are like Assholes

04 P2+ Via DICE Tool

CEM Flash Read Write Edit Checksum PIN READ
DIM Flash Read Write Edit Checksum
ECU Flash Read Write Edit Checksum PIN READ

How about other modules like Haldex?

Watching you bitch about others completing your half-baked contributions is hilarious, when those "others" are so incredibly far ahead of you - Progress wise. I might as well reach out to them to finish the project, they seem a lot more motivated and driven than you.
