Took our Z1 out for the first time and it ran fine until we headed back to the launch. I ran it wide open and the check gauges light ended up coming on. All the gauges were reading fine. I ended up shutting it off turned off the battery switch for 30 seconds and started it back up and cruised at 35 the rest of the way back and no light. Any ideas what could be going on? I read something g about an ecm re-flash for PCM engines but not sure that will fix it?? Thanks.
