The Bazzaz seems to be a better unit in that it controls all eight injectors from the one unit whereas the Dynojet requires a secondary fuel module to do all eight (extra cost and extra kit under the seat).

The PCV seems to have a larger following, and might therefore be more reliable? Lots of posts on firmware issues though.

Both units seem to have issues with Australian G4s. The PCV requires a special part not available outside Australia (O2 Eliminator/optimizer (#76125020)). Can't determine what the Bazzaz needs.

Seems to be issues with a "closed loop system" on both with the Australian G4, something to do with requiring the O2 optimizer AND a second wide bang bung if you want to run either manufacturer's autotune.

I'm leaning towards the Bazzaz but concerned about reliability/take up. I just want to have the right fueling with an Akra + link pipe, half a dozen track days a year, lots of spirited riding, no racing, have an Annitori quickshifter on order.

Comments?

Tks,
A.

I've got your setup pretty much. Akra, link pipe, and K&N... My Bazzaz seems to be working well do far.

Dyno read peaked out at 180HP, and 150HP midrange... Feels smooth throughout, and overall pretty stable.

Lumiera, you run the Bazzaz without a sensor? Is it the Bazzaz that comes with the pre-set maps, or the custom one (needs to be dynoed)? That's if I understand it right ... and there's no guarantee of that.

My factory sensor is still in place... I'm trying to clarify if this causes any issues or not. Seems no one actually knows for sure??

Bazzaz claim that you can remove the sensor with no issues, however then you get an FI light. The negative there is that Bazzaz don't supply an eliminator with the ZX10 G4 kit.

It's confusing the hell out of me! However yes, it was dyno'ed and my mechanic uploaded a custom map for me based on all mods I have installed.

I'm in touch with Gas Imports who are the Bazzaz distributors in Australia to clarify if an O2 eliminator is needed.

The Z-Fi looks like better tech, but I don't know enough about the merits of each yet to make a call.

Is kit ecu an option for you. I like it a lot on my 3rd gen.
Sadly no, I looked into that, it seemed like the perfect solution but it removes some functionality I'll need on the road. For track only it would be perfect.

I so wish Kawasaki would let us access/tune our stock ECUs so we didn't need to have either a PCV or Z-Fi.

Thank you for writing. As far as we know our system comes with everything you need to tune your bike without having to add anything extra. We have not heard from anyone that our system is causing this bike to throw off any FI codes. Please let me know if you have any other questions and I will be more than happy to assist you.

Regards,

Rich McGee
Not exactly the response I was looking for. I specifically asked if anything needed to be done to the stock O2 sensor if you used their autotune module.

Hasn't inspired confidence. I'd rather not have a "as far as we know", that's not good enough. I need a "it'll work if you use parts x and y".

Poor effort!! I've actually emailed the U.S to see if they can weigh in it any advice. And I did try to reach the Aussie product specialist aswell... Just waiting to hear back from either...

The situation really seems to be whether or not to ditch the factory o2 sensor. For autotune I'm hearing you can just get rid of the factory and run the Bazzaz sensor. Then get rid of the autotune and just plug the bung.

My biggest concern is does the factory sensor if running with the ZFI mess with the new map at low revvs? And if yes, should it be pulled and remapped without it?

Or if it has no effect at all, can I just ditch the sensor and use an elim.

No one has the real answers on these issues, and it's very frustrating.

It's all as you say "as far as we know"..."I'm unaware of any problems"!!!

How about testing your products properly and giving definitive instruction?!?!?

Sry, I should have said that was the response from US tech support, I've not heard anything back from the Australian distributor (and I know someone who works there).

I'm with you on the O2 sensor question...

Hi there Mate.
I have been playing for months with this I also have a Aussie model. The Aus model is diff to all the other models ie South Africa which is the same as the UK one and then the American one. The Aus one (as far as I have found out and as far as I have expierenced )if you want to run auto tune on dyno jet or bazzaz you cannot run without the factory lampda. I have tried all diff setups. I had PCV first and thought that the problems I was having was to do with the firmware (anotther Problem all by itself) I then got a Bazzaz which I then picked up the same problem. I have tried what the guys in South Africa do ( a lot of zx10 race in SA as they have the Zx 10 cup) and used the eliminator plug but it did not work. I then tried the eliminator plug into the O2 optimizer which worked for about 500kms and then as I was informed by a friend of mine in SA and also by Joe from dynotronics that it would, it started playing up.
By playing up I mean that it is not perfect on the cloosed area,s of the fuel map, you can feel from 3-5000 rpm at small trottle openigns that the fueling is being affected. On a race track I suppose you would not feel it.
I was told that becuase if the ( intelligent) ecu it lets you get away with it for a while and then fixes the problem.
I am now in the process of speaking to Graves if they cant supply me another lampda plug for my graves ssystem and then I can run the auto tune with the factory lamda
Apparently all the other models including the American model wil come with the same setup next year.

Thanks for that mate. So in my current situation, my bike was custom mapped on Dyno. Now I have the factory lambda connected...

Is this the way to go? Or should I now ditch the factory lambda?

I don't use autotune, and I haven't planned in it...

Any ideas?

I've just ordered a PCV and Australian O2 Optimiser. Less risk than Bazzaz.

I run the 02 Optimiser.

The old ones had an issue but the new ones are fine, can't get into it but that's the deal on that.

From what I know your ECU tries to change your Air Fuel ratio at certain rpm's which helped to get the bikes past emissions testing.

The problem with that is that it effects performance and your Power Commander being a piggy back off the ECU deal, can't take control over that range.

The 02 Optimser will basically wire inline with your factory 02 sensor and should delete the ECU's ability to lean that area of the rpm out.

Ideally I think it should have been dyno'd with the 02 optimser on there but oh well, better late than never.

You need the 02 optimiser to run inline with the factory lambda. The only time you will have a problem is when you want to us the auto tune on either the Pcv or Bazzaz. ( on the Australian Model)

FYI guys, I posted my questions on the Bazzaz forum... Seems like a straightforward answer at last!!

Its a definite, "cannot run the factory o2 sensor with a Bazzaz". Bazzaz dont make the eliminator because the US dont have sensors... Im sending the US Bazzaz team some photos of the sensor connector and the resistance ratings of the pins and they will begin to ship them with the Australian stock.

Gotta love community!

Hope that helps!

What is the o2 optimizer? And where does it install?


Sent from my Motorcycle iPhone app
If you take your seat off and take of the right hand side tank cover you will be able to follow your 02 sensor wire up to the right hand side just under your tank and you will see where it plugs in.

You are unplugging the 02 sensor, then plugging it into the 02 Optimizer then plug the other lead from the 02 Optimizer where the 02 sensor originally plugged into.

Think of the 02 Optimizer as a signal filter which just sits between your stock 02 sensor and where that 02 sensor originally plugged in.

In terms of what it is, I explained that in my previous post in this thread :mrgreen:

If you still have questions, fire away.
