can i do relative compression with a synch?

Post by blake »

I had a vehicle that had a dead cylinder and a weak cylinder that showed up during the relative compression test using the pico diagnostics software. my question is can i add a synch cylinder to that test so i can use the firing order to determine the dead cylinder and the weak cylinder? the vehicle had plug wires so i just wanted to use my inductive pickup probe for my synch cylinder.

Any help is appreciated,

Blake

Use Picoscope (not Picodiagnostics) and measure starter current with amp clamp. Sync with one of cylinders.
