No problems to discuss, just a little info/advice on a mini crank and cam waveform I captured.
I'm just starting to grab some waveforms to build up a database, but found the readings from this mini strange. (or at least strange to me!)
This engine has 2 cam sensors, so I assumed they would trigger at exact same time. Seems not. Does this appear normal? Car has no running issues etc, was only in for roll bar bushes
All this stuff is new to me, so just trying to gain knowledge etc. I gathered it was ok, otherwise running issues would happen. It's just I expected to see both cams trigger together so was more curious as to why they didn't I guess.
I guess that was taken at idle, in which case if the vehicle has variable valve timing it would be advantageous to open and thus close the inlet valves later to improve idle.
Yeah, sensor on each cam. I don't think the engine has variable cams, but could be wrong. Customer was on way for car so had to get it off ramp quick. So yeah, your thoughts could be correct.
Main reason I wanted a cam/crank capture is we have a 207cc coming in with running fault (same engine I think) so thought it would be handy to have!
Very old topic, but might as well reply.
This looks pretty normal to me, for 1 thing.
I have a Peugeot 207 here with a 5FW engine(Dual VVT), based on the same engine you are having in the mini here.
When i compare your signal to mine, it doesnt add up, and i also had this with the 5FX version on a 207 once. The signal is completly inverted to the one from the database. Your crank trigger signal has a long "High" while mine has a long "Low"
Also had this happen to me once with a Peugeot 207 THP with just the single "variable cam".
So thats what struck me as odd. Did you happen to capture the Peugeot data you mentioned in your first post. Like to get to the bottom of this
