I was wondering if there is any way to set up a cylinder efficiency test with a vacuum pressure transducer on the verus pro?

Probably could use a trigger off cyl
#1 fuel injector for one channel and attach the pressure vacuum transducer to manifold vacuum on another channel .
I would probably use the Amp Probe over the battery cable and identify low compression by differences in amperage draw of starter -
I would recommend using the spark of #1 cyl to set the base time correct. Using an injector will throw you off a few degrees, as the piston is on the intake stroke when the injector fires.S. BrelandComment

Don't use an injector to sync your waveforms unless you have a specific reason to. You don't always know when it will turn on in the four stroke cycle, or if it will turn on multiple times.Comment

Cylinder compression
Hello
I would agree on the amp clamp on starter motor
Here is a you tube vid of how to set up your verus pro
Look for good repetition on a poor cylinder the compression humps are lowerComment

I also saw a burn time graph under cylinder test menu and tried it on a 2000 Dodge Neon that had a miss at idle, but no misfire codes yetAttached FilesComment
