We got a strange and annoying Lambda Hickup problem right after startup.I tried 2 ECUs with different firmwares,36 and 38,both made the same thing.

Here is a cloosed loop datalog,its really huge,but u will only have to check the firs 2 min.There u will see a sudden PW drop where Lambda starts to read.

Will do more logs (shorter ones:) with openloop too.


I've got the same problem, every time the lambda starts to display, the engine "hiccups" or stops. Even if configured for open loop (eg. Min RPM = 25000 )

I'm using v3.2 firmware 38


Problem investigated and traced to a ego converging change some time ago, fixed in current svn, awaiting release
