BMW ignition waveform

[GTA matt]

Thought I would share this. I am still relatively new to using my low amp probe but I try to pull it out whenever possible. Had an 07 BMW 330i with a misfire. Luckily BMW made it easy to get to the coil wires. I've been doing Fords at either the fuse box or at the connector near the pcm and have known about their multi strike ignition, but I thought it was "neat" that BMW was firing the coil 7 times per cycle. As soon as it comes off idle it goes to single fire. This is from a good cylinder.

Very cool!

Hi Matt,

Great job on the coil capture. I was unaware that that engine has a multi strike ignition.

Did you use the Verdict's camera for the engine compartment pics ?

The reason I ask, is that you could take the pic and hit the "s" button to take a screenshot instead of using a camera. You could have it all in a folder for later reference also. Also, you could literally post directly from the Verdict.

Just an idea.

No I was using my cell phone camera. I had taken some screen shots but just now learned how to transfer them to photobucket. Much better! Thanks for the tip.

Good Capture.

Much better. Thanks for that, capture looks good, good time base, good scaling. You should upload that to the waveform database.

The only thing you could do better is get the full screen in (press the thumbprint button).

You mean Iatn? Or is there a new one for this forum?

If you have a COP-11 adapter you can also get a good look at the burn time with this adapter, I sometimes like to overlay all three waveforms with my Verus Pro. The COP-11 does a great Job finding ignition secondary problems.
Take care Dynodave
