Post by dll67 »

Im trying to chase down a lean spike to a particular cylinder and would like to know if its possible to data log the spark outputs?
Thanks Dave

What about piggy backing off the inputs to the coils and running them into extra JBPerf IOx inputs and datalogging them from there?

The spark control pulses are very short and a regular datalogger won't pick them up.

The MS2 and MS3 firmwares include an "Engine Logger" that can record fast engine events. You need a registered version of TunerStudio to see that option in the High speed loggers.
