Member Contributer Ranger77 Posted July 19, 2011 Member Contributer Share Posted July 19, 2011 It never stops, does it? Moving onto my next project. Since I don't feel like modifying the 6th gen airbox, I'm just going to go this route. 1 Quote Link to comment Share on other sites More sharing options...
Member Contributer kaldek Posted July 19, 2011 Member Contributer Share Posted July 19, 2011 Are you sure that's going to work mate? The three pins aren't "an extra ground", the third pin is the trigger. So, for example on the 6th-gen there is a constant 12 volts and ground provided to the coil and the third wire is the trigger. It's basically a simple transistor if I recall correctly; any 12v signal (regardless of strength) trips the transistor, which cuts the normal 12v source and causing collapse of the low voltage field and hence generation of the high voltage spark. But anyway, are the 5th-gen coils also three wire? If they are, your two-wire coil-on-plug system won't work because the ECU only activates the high voltage coil by sending a trigger command to the coil as opposed to actually cutting the 12 volt signal directly in the ECU.

Member Contributer Ranger77 Posted July 19, 2011 Author Member Contributer Share Posted July 19, 2011 (edited) 5th gens are just two wires. Out of all the bike coils I searched on ebay, the 6th gen vfr's were the only 3 prong coils. Edited July 19, 2011 by Ranger77 Quote Link to comment Share on other sites More sharing options...

Member Contributer Ranger77 Posted July 19, 2011 Author Member Contributer Share Posted July 19, 2011 (edited) Ya, these Denso's (without flap seals) are used on just about anything. The ones on my ER-6N look exactly like the ones used on other kawa bikes and gsxr 1000's. I was google imaging them and a lot of four banger import engines use them too. All look the exact same. These new model gsxr's have the slick looking metal mid sections. It's bling you can't see. LOL Edited July 19, 2011 by Ranger77 Quote Link to comment Share on other sites More sharing options...

Trust Honda to be "different" as always. Like everyone else using wideband O2 sensors now, except Honda. Quote Link to comment Share on other sites More sharing options...

Member Contributer kaldek Posted July 24, 2011 Member Contributer Share Posted July 24, 2011 Awesome mate! So is that now running with the 6th-gen throttle body and injectors as well? Quote Link to comment Share on other sites More sharing options...
Veefer800Canuck Posted July 24, 2011 Share Posted July 24, 2011 Hey, right on! Why not just use the CBR1000 stick coils then if they are 2 wire coils? Were the Suzuki ones just cheaper on Fleabay? Quote Link to comment Share on other sites More sharing options...

Member Contributer kaldek Posted July 24, 2011 Member Contributer Share Posted July 24, 2011 What is the added advantage of moving to these coils ? Coil on plug gives a higher voltage and better spark. However, the 5th-gen already had dedicated coils at least, so the difference isn't huge.

Member Contributer KevCarver Posted July 24, 2011 Member Contributer Share Posted July 24, 2011 Cool! I know some of the RC51 guys have done this with the CBR stick coils. Nice work getting them at $9. Quote Link to comment Share on other sites More sharing options...
Member Contributer AnikMankar Posted July 24, 2011 Member Contributer Share Posted July 24, 2011 That is what I assumed. Those plug wires look short and sure to be exposed at the front side. Enure you use some silicon joint to water proof them Quote Link to comment Share on other sites More sharing options...

Across which pins? Beats me. The fsm doesnt state anything on ohms with the coils. On two prongs i just touch the two. No clue on the 3 prongs the 6th gens have. Im getting around 3.1 ohms on the 5th gens and 1.6 ohms on the gsxr's. Quote Link to comment Share on other sites More sharing options...

Member Contributer Ranger77 Posted July 25, 2011 Author Member Contributer Share Posted July 25, 2011 She seems sluggish now at low rpms and taking off. I'm going to hook up the stockers tomorrow and see if it's the bike or just me. It would be nice to find some that are the same resistance just for the assurance. If you can test yours, I'd greatly appreciate it. I'm going to test the ones on my '09 ER-6N and see what those are at. I'm gonna guess that these coil on plugs are gonna be lower than the old school styles. Quote Link to comment Share on other sites More sharing options...

I'm gonna guess that these coil on plugs are gonna be lower than the old school styles. Verrry interesting. I'll check mine tonight but since they're 3-wire coils the results may not be comparable. It could be that these new coils are pulling so much current from the ECU that it is suffering a brownout. Your old coils pulled 3.7 amps each (since they are 3.2 ohms at 12 volts), the new ones pulls 7 amps each. Granted, these are "pulse" figures but that's a doubling of current. I've heard of people using ballast resistors to increase the resistance but then that might affect the spark, because each coil WANTS that 7 amps. More Googling required, methinks.
