You've got a race condition, as I said l said

If ou have log files PM me with the CANiD 9origian car logs not you) button on/off times stamped.

If it's what I think it is I can suggest  a code change I solved it before.

ok looking can't sleep anyway, next time an xls will be handy (csv format actually)

I normally import it and T-SQL the crap out of it

re overrides, does VCDS or whatever support 'activations' this would be far easier to implement.

But watching fro a byte change in a loop is also easy

Sending the the byte change has to e done correctly..

Also prefix with 0x when using hex please, sorry it's a pet hate.

Yes you can, as you pointed out.

So try and do a <30ms cycle use it as as a const and play with it)  and beat the steering wheel to the punch perhaps, there's no counters or anything I've sen on 29bit cars to worry about there.

That's my theory and iirc it  with canbus theory/docs.

You can also look into msg priorities, which iirc is part of the canid bits.

Speaking to my mad self.

I managed to beat a race condition here

But there was a counter on [04] iirc that I had to grab and increment then beat the race condition between modules, more difficult that you I think, so you should do it.

Not sure I'd do this on the ECM bus mind you, bus off whilst driving is not fun (been there).

Except for writing to the cluster for my boost gauge I always used diag commands to avoid this problem.

depends on the mask and filter??, hey man I'm just throwing ideas out, I'm highly skilled in CAN bus/freaking so I can try to help dude, few posts ago you said everything read everything unless i misunderstood.

I/We ended up writing out own code for J2354 and dealer units, mcu libraries were not cutting it for what we were going towards..

Couldn't get chipkit to communicate on 125kbps CAN for example, arudino yes, both open were using source libraries.

For example my MCU puts boost on the cluster 16x2 display (vid above), has a menu system using cruise buttons, folds mirrors in on lock, shift light (lol) etc and datalogs he ECM at the same time.  Sounds similar?

So been where you are man, what language you writing in in?   Perhaps I'll see something if your using an online private repo (couldn't care about seeing the code man, wrote enough of it myself lol)

hope this comes across nice, don't mean to sound angry or pissed but haven't slept so can't tell, but I am interested in helping an seeing VAG can.

Arduino with canshield works nice but only one controller, chipkit, I suspect library is shit,  I can send the freeware libraries I used for both 500k and 125k busses for canshield it's nice to see this stuff tbh.  Most people would just reverse engineer something similar, even companies....

Also most folk on here are playing with kline....so maybe not much more input idk for sure tho
