WBO reading stopped with 3.3.1a firmware

Post by radics1 »

HI,

Megasquirt 2 V3.0 3.3.1a firmware
i got a problem,after a few hours,the WBO reading stuck at 14.9 and did not move. I put the MS on the stim,it still does not work as expected,is shows 14.9 if the o2 pot is turned fully off and 16.7 if turned fully on. I recalibradet the wbo setting,but still the same. If i try other wbo settings,shows different numbers,but still not good.

I had one other CPU on hand to test if the board is faulty. Works fine on 3.1 RC1 (3.0.3y). I reloaded the 3.3.1a again,still the same result. Then uploaded the 3.1 RC1,wbo works just fine.

What could be wrong with the firmware? It looks like it is a software issue now. Once I had similar problems with a beta release,then i went back to the good old but stable 3.1RC1.

Any help welcome!

At the very end at 2000s you can see,that the WBO reading suddenly stayed at 14.4

Now the Pre3.1 RC1 was uploaded,the car runs fine,wbo works as it should and this weird sync loss at 5600 disappeared,now it revs to 8k easy.

Dont know what could be wrong with the new firmwares or what i do wrong,but had similar issue a year ago,but dont remember the FW version.

The car is a Clio 16v running on 44-2-2 renix trigger wheel and VR sensor.

I tested your MSQ on the bench and I'm not seeing anything obvious.

How about other stable releases?
e.g. the previous stable code 3.2.5 ?

I would suggest you try those rather than an obsolete beta version.

Did not try 3.2.5.

Obsolete? It is written in the MS2 support topic,that this is the latest stable version and everybody should upgrade to this version here:

3.3.1 isn't obsolete!
You said that you were using "Pre 3.1 RC1" that is certainly obsolete.

Do you have also WBO issues,or only with the trigger? Did you try the 3.2.5 as James recommended?

How this is relevant to this topic about wideband O2 readings ?

Posting random stuff in different topics is considered spamming. DO NOT DO IT.

You've already tried to discuss this issue you have in three topics now. STICK TO ONE TOPIC.
Last I heard, you said you had fixed it ?
