[QUOTE="Rednaxs60, post: 209240, member: 4617"] Came to another issue last night. Lots of info to digest. I have the travel computer on my bike, great piece of kit, still haven't figured out or used all the functions. It's a legal driving while distracted device as it is incorporated as part of the bike. I'm certain it uses a lot of the signals from the sensors to provide the info it does. Went onto the DIYAutoTune website and found its article on wiring the MS in parallel with the OEM ECU so that I can keep the travel computer functionality, but use the MS for engine operation. The article does mention that there are signals that the MS does not like to share so will be looking into what is needed. Have read socrace's thread on coil on plugs (COP) on the NGW forum, and how he achieved the upgrade. Also found a YouTube video where a car was upgraded to COP, car had a wasted spark system as well. The car video just split the signal to the original coil into two and connected the new COP units. Socrace's is a bit more involved, but there is always more than one way to achieve the aim. I like the COP concept and application. It has benefits that the OEM wasted spark setup does not, and it is less expensive. Would like to see how socrace married the COP to the OEM plug boot. This upgrade would be beneficial even if no ECU upgrade/replacement is done. It was commented on in an EFI thread that the original CFI system, while functional, lacked the nuances of the newer technologies, yes I agree, but when Honda did this back in the '80s, state of the art and on the cutting edge. We now get to reap the benefits of the past 30 odd years, and can keep these older FI bikes on the road, and see what can be done with the ability to do tuning. More to follow. Cheers [/QUOTE]
