This is good news. If this has the abilities you suggest, I'll probably buy one even just for the 2020s.
I'm still trying to figure out how the ECU or regulator caused the ring/land to break. If anything, that piston looks like it was running a wee bit rich. Also, if it fires on both but then drops one cylinder, could this be some sort of "limp mode" that's still thinking the PTO side isn't right?? Is there a code that needs cleared before it continues to run on both holes?? Does the SDI even do this?? Like shut down the offending cylinder because the sensors aren't sensing proper combustion so the ECU shuts down the offending cylinder?? Does that make sense?
For the firing on one cylinder, the only way to know is with an Ignition Timing Light. A spark tester can also be used, but it has its limits as it doesn't show timing. Without the use of an Ignition Timing Light I consider the diagnoses a guess at best.
For shutting down the offending cylinder, no. A protection mode of any kind will affect both cylinders equally. There is no way to know why in this instance only one cylinder is being affected without proper troubleshooting. Anything else is a guess. First thing is to connect to BUDS/CanDoo and reset the TPS.
I apologize to being direct. At this point I am finding myself in a situation I shouldn't be in, which is commenting on a sled that is currently being worked on by another tech. In my opinion it is poor etiquette on my part. I much prefer giving my thoughts on a sled that is being worked on by the owner.
