Re: MY00 GC8 with AVCS don't start
syncscope would tell you in a few seconds whether the signals from the crank/cam were viable.
Re: MY00 GC8 with AVCS don't start
So I tried with syncscope but it seems I made something wrong, I don't have any log file. I decreased the limit to 0 rpm with no chance - I have the red message : No log found.
It could be explained by the fact that I have no rpm signal on the gauge in Scal
Below this is a screenshot of gauges before starting
AN01 = Crank Sensor - I have G11 wheel
AN02 = Cam Sensor
AN03 = Cam (Inlet 1 Variable Valve Timing) Sensor [LH]
AN04 = Cam (Inlet 2 Variable Valve Timing) Sensor [RH]

Good new id that I have a signal for crank now
During start (please consider only the left of the curve)

The crank signal seems erratic for me. I unplugged the injectors, so no real attempt to fire up the engine, I just wanted to see the signal.
By the way it seems I have no rpm signal at all. I can't see any variations on the gauge even when I changed scale to 1.000 rpm instead of 10.000.

Re: MY00 GC8 with AVCS don't start
you need to get a syncscope.
The manual or maybe a youtube video should explain how.
Or upload your cal in case there is something wrong with the trigger setup.
Those little on screen gauge graphs are no good for trigger diagnostics.
And what crank/cam trigger setup are you using ? Baring in mind it's a GC8 chassis, but you also have AVCS....

Re: MY00 GC8 with AVCS don't start
So I tried to make syncscope and I stored the files in my drive below
https://drive.google.com/drive/folders/ ... sp=sharing
I also add my engine map "MY00 - TBG based 20181022.sc" in the drive.
I have G11 trigger wheel for crank and cam. Thanks again for valualbe help.
In the log above, injectors are not plugged in.

Re: MY00 GC8 with AVCS don't start
I see no synclog in there ?
And you are definitely using a G11 crank and cam trigger setup ?
Some of the voltage thresholds seem a little high, and there's a filter on for the cam, which probably isnt necessary. But without seeing the syncscope to see what the ecu is actually seeing....all means nothing.

Re: MY00 GC8 with AVCS don't start
Ok, I tried again to make a Synclog. Please find the result below

And Yes, I'm using a G11 crank and cam trigger pattern

Re: MY00 GC8 with AVCS don't start
the file would be better than a screenshot. (* edit, just seen the file there )
But it looks like you've wired the crank sensor the wrong polarity.

Re: MY00 GC8 with AVCS don't start
Ok then, so I inverted the wire on the crank sensor. As I repaired the wires, maybe I could invert them in the connector plug.
Now it seems better I think

Re: MY00 GC8 with AVCS don't start
It is now getting to 720 sync, so if all other aspects are set up correctly it should be able to start and run.
Re: MY00 GC8 with AVCS don't start
I'm just wondering if there isn't another mistake with AVCS sensors. I can see that the both curves are very similar and maybe I will have another problem with this.
What do you think ?
