This is the last of my bugs to work out on my Sunsport, and actually it may have been caused by the dealer. I have an Indmar 340HP CAT ETX (08 sunsport 22v), I kept getting the maintenace required prompt on the center console display. Took it into dealership #1 they ordered a new 02 sensor, installed it but could not get the maintenace required prompt to go away. I bought my boat from dealership #1 that lost Supra boats, they now tell me I have to take it across town to the official "Supra" dealership #2 to have them properly reset the computer. According to #1 they dont have the updated software and Supra wont give it to them because they no longer sell Supra boats.
So everything seems fine after I take it across town to dealership #2, they get rid of the "mr" light, and I take the boat out the next day and everything is running perfect. I turn on the wakeboard pro v6.5 and set my speed and plate in manual mode, etc etc... boarders in the water, go to give it throttle and nothing... I have no throttle response at all when perfect pass is activated now. I can engage the throttle 100% and will get nothing but a slight hesitation at 100%. Almost as if the boat is missing. If I turn off the perfect pass the boat responds and runs perfectly. Anyone have any ideas?
The ironic thing is the perfect pass worked fine before I took it in to have the 02 sensor replaced. The dealership #2 that sells Supra boats is trying to figure out what to do but it sounds like they really do not know whats going on. They are contacting Supra techs to help them out. I also have a couple contacts at Supra that are looking in to what could cause this problem. One person mentioned the ECU was loaded with the wrong software and it cant communicate with the wakeboard pro?
Just thought I would post this to see if any mechanics out there have encountered this problem, and I could pass it along to the dealership. It would be nice to get this resolved sooner than later.
Thanks fo any input anyone has that I might pass on to the dealership working on my boat.
