R6 ECU Technical Questions
Hey everyone- My name is Jimmy, and I am a powertrain engineer for a company in Detroit. I am working on a project involving some electronics and ecu tuning on an '08 R6 and R1. I am sure there is a ton of knowledge on this board, and I am hoping that someone can help me learn a little more about the fuel system and ECU management on the R6.
So anyways, here are some questions I need answers for. I am a frequent poster on several other message boards, and I am aware of the typical 'search' or 'rtfm' responses. I have done an extensive amount of research already, so please don't just tell me to use the search key. I already have.
First, are there any current manufacturers of bolt-on adjustable fuel pressure regulators for yamaha platforms? I am aware of the yec reg that is discontinued. I have searched and searched, and found nothing. If anyboy knows of a manufacturer that produces such an item, please point me in the right direction.
Now for some tech questions about the ems yamaha uses on these bikes; is there a fault code or scan system other than the 'gauge cluster' fault code scan on the bike? We are running these bikes on a dyno, and want to be able to view, real-time if at all possible, the fuel trims the ecu is applying to the tables. This is a built in function of every factory scan tool I have ever used, but it appears there is no scan tool for Yamaha.
Second, does anyone have any info about the fuel adjustment schemes in the factory ECU? Specifically, does the bike utilize a long term, short term, or hybridized scheme for adaptive fuel trim? We have been trying to figure this stuff out, but everyone at Yamaha is (not surprisingly) very reluctant to tell us about the programming system they have in place.
Anyways, if anybody has any of this info, I would greatly appreciate the help. Feel free to pm me on this forum if you don't want to post in my thread.
Thanks in advance!
