I was hoping to find a really cheap used one on Ebay so I could try it and see if it was any better, but it would probably be a waste of money anyway. My problem began after I was riding at very slow speeds practicing figure eights and u-turns in hot weather for 30 or so minutes, and it could be that I fried the ECU. It wouldn't hurt to talk to Don Guhl, too, to see what he thinks. If he can up-date the ECU for a reasonable price, it might help someone else and give him a new venture.
I don't know...there's been about 40 riders just on this forum that had the idle issues and maybe a common denomintor was that it started on a warm to hot day, but other than that, who knows. Seems to me there was simply a batch of ECUs that came out defective. Maybe the robot had a rough weekend and on Monday it just couldn't get it together.
That is quite plausible. A batch with marginal electronics, maybe a simple capacitor that deteriorates after prolonged high temperature exposure is not a profound possibility.
