Nice

Fixes: • Resolved a rare stability issue that, in specific conditions, could result in an ECU restart.
I actually noticed that about 3 times within 15000km I’ve covered. Very annoying given the DSG won’t let me restart on the fly - engine torque just disappears and I have to move my shifter and stop.
Still have no reliable steps to reproduce so never posted. Just wanted to ask about the RESET CAUSE - mine were logged as WDT afaik. Could you update the description?

Also CWA400 not 500 (only in the post. correct everywhere else)

Yes, that’s the same exact problem.

Two questions: Pro 8 or Pro 16 - and are you logging to a USB flash drive?

5

Pro8 on the car I’m talking about. Logging always yes.

Pro16 on another and logging but it’s not being driven much and it’s used as a secondary ECU. Haven’t had the issue yet

Maybe i met something similar with unstable USB logging(its just stoped and not start again until engine restart, pc client logged no problem at same time). Maybe this update will help.

But im just here to ask, is it somehow possible to jump between Graph log tabs? When i have several of it, on smaller laptop starts some be hidden on right side and i cannot reach them until rearange layout of whole screen.

And two small things:

The BLACK can stream is transmited only 20hz, on Black ecu is 25hz is i remmember right.

When i connect VW Hitachi MAF sensor , it gives 0.58khz at zero flow, and MAF sensor setup option has minimum limit 1khz, so it throwing error.

Thank you for confirming. We were able to reproduce it only on this exact setup.

I think the fix will not affect USB logging. Check our technote about logging to USB in EMU PRO.
What brand of USB flashdrive are you using?

We will check.

Good to know. I’m not sure if we can lower the minimum limit. I’ve recorded a change request.
