So...
I made the assumption that the yellow and red wires were the ones I was meant to switch and the black wire was to stay in its original place?
By crossing the yellow and red wires over the result stayed the same. Front plug sparked, rear plug didn't. According to cvincers doc that would imply my TCI is boned?
I peeled off the glue the PO had put on the unit and took it apart. There is evidence of a little solder work from one of the 6 pin pins but nothing appeared loose. There is also some melting of the outer plastic case where the 2 metal brackets that are screwed to the circuit board slot into the case.
I understand the TCI's are a bit hard to come by. Anyone got one for sale?
Oops...not sure how this ended up here. It won't let me remove it either. Disregard
Try sunburnedaz
Yup I have a few now thanks rick. LOL I can test one and send you it after it works, shoot me an offer.
Hi Tig5, Oops double posts all round :-[ Never mind Sunburnedaz may not have seen this otherwise.
I have just tested my XZ400 TCI unit on the 550 and it works fine. If you would like me to post it to you so that you can test/ check if your TCI is the source of your problem before you buy one, happy to oblige. Text, Phone or PM with your details and I will get it in to the post for you. All the best. John (pinholenz)
Someone, I don't remember who, suggested that the XZ550 goes a bit better with the XZ400 TCI installed. I run the 400 unit, but have never done a comparison.
If there is a difference it would almost have to be in the advance curve and I would bet that the 400 has more sooner for better bottom end. A 400 box might give the 550 better mileage and bottom end although it is already good a little more couldn't hurt. Love to see a comparison.

Someone posted these a while back but I have no idea who or if they're right...
I posted them - sourced from Yamaha manuals. that's no guarantee they are right of course.
