Anyone know of any tuning house that supplies these? I put an ad in parts wanted. Correct me if I'm wrong, but iirc Dynojet/Powercommander have discontinued selling these as individual parts. I have alternative brands but prefer the DJ/PC version.

I have the kit that contains the PCV and the O2 optimizers that I had planned to put on one of my 696s but decided against it.  It’s new in box, never used. 

I bought it specifically for the 696 but I can’t imagine it won’t work for the 1100 since I think they share the same ECU (with diff mappings I assume)?

If interested, let me know. I was just about to put it up on eBay.

Thanks. I already have the PCV and a spare Bazzaz. I was only after the O2 sensors.

The dyno showed the PC O2 sensors gave an AFR of 13.6 in the closed loop section of the map which provided sharp low rpm throttle response and good fuel economy at cruise.

No probs. Would like to sell it all as a package.  Let me know if you change your mind!

Tony do you think one from a Hyper, or Multi, would work?

I am confident the Optimizer/s from a Hyper 1100Evo would work as would those from a non Evo M1100 due to both running Seimens ECU's. I tested both two individual single channel units from an M1100 and a dual channel unit that came off that model. The difference is the dual channel is one box with two sets of wires and a fancy sticker. The individual units just sit inline the connectors with no control box so much tidier. Both being PC versions meant that they weren't found out by the ECU or ran too rich clagging the O2 sensors (and triggering a CEL). Im not confident a non Evo Hyper or MTS1100 version would work due to the Marelli ECU.

You know of some laying around? Grin

Look kind of pricey, but there you go.

Looks like the same seller in Spain has them. Maybe he'll combine shipping if you can make a deal.

I'm pretty sure they're Marelli type Optimizers .
A re flash here from bikeboy is a similar price to a pair of those so I'll keep an eye out. Something will come up.

How do you tell which type they are?

From the bike model although the devices outwardly look the same. Multi 1100DS and Hyper 1100DS ran Marelli while M1100, M1100Evo and HM1100Evo ran the Seimens. I'm working on the assumption they are specific to the type of ECU.

So, these things are full of resistors to mimic the behavior of an O2 sensor?

Is the sensor part number the same across the models? Is the plug?

 My understanding is that the outputs from the various automotive sensors are pretty standard.

I hope you're right Q. I don't know for sure and working on an assumption. In also not banking on the connectors being the same but that's easily fixed. Smart moto in Greece had different parts between Evo and non Evo models iirc. I'll go back and check.
