SecTrigError?

Hello Vems,

Could you help me to analyse this log?.
I was steadi ly driving at 60km/h entering a tunnel. At the time swiched on the lights (0.:3.88) the engine shakened badly, made big noise, big smoke behind the car, seemed to have no more power.The engine stoppped with clutch off and car still moving. Then the engine restarted ok clutch on car moving.

It seems to me that I went out of sync. However I noticed that the lamda was quite rich and that there can be an accumulation of gaz. Indeed for this new config
- dTPS/dT lowest level was set to 8 instead of 9 and accel enrich was on most of the time
- fuel film and lean option was on.

Thank you for your analyse

Best regards
Philippe

Hi Phil,

Thanks for the update, very nice wiki report as well,

Best regards, Dave

Hi Vems tem,

fw 1.2.32
I made a triggerplay file .wav, here attached, to simulate the lost of 1 prim trig. There the missed trig is the last trig before the 1st sec trig.
The triggerlog here attached shows that indeed:
- the trig error is acknowledged
- the missing pulse is estimated and that an ignition event is then sent about in time
- ignition firing stops afterwards
Although
- there is an extra last firing sent on a bad phase before ignition stops
- it seems that injection is still running.

In any case it seems much better and quite safe now.

Best regards

Hello Phil,

Thank you for your update on 1.2.31 with z012 (Maserati trigger) on real car. I am very interested in hearing about your continued observations, should there be any problems please report; I'll look into it.

Best regards, Dave

Hello Vems,

I have run fw 1.2.31 on the car today for about 70-80. I made about 5-6 restarts. This version works good.
I did not test the modification done for missing low count tooth., although I switched on and off the lights but the wheel speed cable which I suspect to cause perturbations was off.
I shall do some tests when I hand a scope.

Thanks for your attention. Best regards

Hello Marcell,

Great. Glad that my case has been somehow useful. I am with car, I cannot upload 1.2.31.

Regards

Hi Phil,
1.2.31 fw is more strict in the special low-toothcount triggers when trigger noise is present, eg. pulses are injected or missing (disables ignition until resync).

Hi,

Thanks for your answer.

"So the options are: high quality trigger signal, or reasonable trigger pattern. "
Coil type gives a low tooth count in any case. Even with a high quality trigger signal, one may get a default, (per ex. because a ground problem had occurs for the first time)

I believe that an operational sotware should detect those trig errors and take proper action. Or, at least, let people know that there is no trig error management with the coil type set up and that there is the risk for the engine.

This does not seem to be a big fw update to check if an incoming pulse is in the good window or not and if not resync (per example)

Best regards

Hi Phil,

> I believe that an extra pulse or a missing pulse should be detected by the fw

For a reasonable setup like a 60-2 an extra triggerpulse (noise pulse) does not cause serious out of sync. For a low toothcount setup (which is a bad idea in general), the trigger pattern should be high quality signal (it would be interesting to see why the lights effect it, maybe grounding can be improved ?). So the options are: high quality trigger signal, or reasonable trigger pattern.

Switching on lights influencing trigger is almost certainly a grounding problem somewhere.

notes: apparently low toothcount Maserati trigger

Hi, Further analysis shows that the out of sync occur since one prim trig was missing. I need to understand whats going on when I switch on the lights.
In any case I believe that an extra pulse or a missing pulse should be detected by the fw in order to avoid an engine still firing out of sync (clutch on) which is much dangerous.

Hello,

I was able to record the triggerlog of what may have happened last night when I switched on the lights in the tunnel (busy traffic). I did it at my parking slot this time ;). See attached.
I was switching on and off the car lights. I noticed that sommetimes the engine was accelerating or slowing. In the worst case it stops.
This is what is shown at the end of that trigerlog. I got other triggerlog.
I cannot understant why the genboard comes out of sync.

Best regards

Philippe
