2006 Charging System?

[rockabill]

Please tell me that they upgraded the stator on the 2006 model! Has anyone been able to tell if the charging system has been improved?..... ::closeterm:

 

[radman]

They've added a power outlet, as well as a heated o2 sensor, they damn well better have.

 

[Warchild]

I'm fairly certain they would have mentioned it had they actually upgraded the alternator, because that is not a trivial change.

While I haven't yet heard anything official, I suspect we are still saddled with 490-watts, nominal..... :angry:

..., as well as a heated o2 sensor, ...

Good, finally! I can't tell you the times I've had to pull over and heat up the O2 sensor with a hair dryer.

The heated 02 sensor has been there since the beginning.

Damn, no wonder those other FJR owners kept looking at me funny...

The O2 sensor in use now is not a heated unit. It's a two-wire device. A heated sensor will likely be a four-wire device.

Correctamundo. And most heated o2 sensors I know of are heated only until temps come up in the exhaust. But the fact remains, Yam has added more electrical goodies (I forgot to mention 2 fans now instead of one) but no increase in output from the alt. At least not that they have promoted. And that blows.

So, the “The Original” [SIZE=8pt]®[/SIZE] o2 sensor is a two wire, unheated type and "New & Improved" [SIZE=8pt]®[/SIZE] has a four wire heated, eh? Who knew? Better yet, ask me if I give a rat's ***. Sheesh. :****:

Do you give a rat's ***?

Actually, Tdub, it's more significant than you think. It's the next stop on the emissions train. It means a more complex set of instructions loaded in the PCM, which could affect add ons like the Power Commander. Next will be before and after o2's, tighter fuel controls, etc. As fuel and ign controls become more complex, so does the cost and difficulty of modifying them.

 

[Mogan]

for those of us that aren't technical, what's the impact of the non-heated sensor provided on current fjrs?

 

[XJRGUY]

The O2 sensor in use now is not a heated unit.  It's a two-wire device.  A heated sensor will likely be a four-wire device.

No, it most definitely is not.

According to Yamaha's OWN technical literature on the subject the current design has been using a HEATED Oxygen sensor since the machine was released.

If you don't believe me see this link and pay attention to pages 18, 31, and 39.

It is and always has been a HEATED sensor.FJR 1300 Technical Guide - YAMAHA PDF

No matter what the Yahmaha guide states, a two-wire O2 sensor does not use a heating element. On a 2-wire O2 sensor one wire is for ground and the other is the signal wire to the ECM. A 3-wire O2 sensor use 1 for ground, 1 is 12 volts (heat element) and the last is for the ECM signal wire. A 4-wire O2 sensor uses 1 12v and a ground for the heater, and an extra ground an signal wire to the ECM.

Heated O2 sensors are used on cars/bikes to get the O2 sensor up to operating temp more quickly (about 600 deg F). This allows the ECM to go into closed loop sooner, thus producing less emissions--an important factor for EPA testing/certification. The addition of a heated O2 sensor and "new" EFI (whatever that means) should not be a problem regarding the use of a PCIII.

what happened to your aftermarket version with the extra windings?

Warchild - I'm fairly certain they would have mentioned it had they actually upgraded the alternator, because that is not a trivial change.

Makes pretty good sense, except why waste a wire for ground when the O2 sensor is screwed into a perfectly good chassis ground. Then the second wire could be the heater wire.

While we are not done doing the R&D on this issue, results thus far aren't what we expect. A bigger alternator right from the factory would certainly be the right way to go.

 

[yamahlr]

Instead of a bigger alternator as many on this forum have requested, we got the electroshifter,doesn't get much better than that.

RadioHowie, Sorry the second wire is not a ground for the O2 heater. O2 sensors have been around for 27 years on cars and NONE of them have that configuration. 4 wire O2 sensors have redundent ground. Exhaust systems are often made from stainless steel that doesn't conduct well. All sensor grounds for the ECM are very sensative to voltage, hence the deticated ground for the O2 signal wire.
