I have 14 PS3 engines and really no problems. I do have one that is two years old that has recently developed a ditch light problem, but I doubt if this is PS3 specific. Other than that they all work just fine, no problems. Maybe I am just lucky?
Wiring my current layout following Barry's guide lines as closely as possible has eliminated what few minor problems I did have early on with temporary layouts. Those problems affected PS2 engines as well and were the 'Engine Not On Track', 'Engine Not Found' etc. errors, usually from poor signal or in my case most likely from having just one continuous loop and no blocks so the signal was over running itself. I did not think this would make a difference on these small layouts, but correctly wiring my permanent layout has apparently proved me wrong there.
