    A GT Exclusive; Tried a FatDuc? This is one done right.

    The PC-V/02-OPT is available for the 15RC (Breva/Nevada 750, V7C, Cal Vin, etc.) or the newer 5AM (All new CARC Guzzi). 2011+ models with two 02-sensors/lambdas, will require two (2) 02-optimizers FOR NON-PUBLIC ROAD USE ONLY.

    Re: New to Market - 02 Optimizer

    Good work Todd,

    What is the difference (what is done right) between this unit and the FatDuc?

    Re: New to Market - 02 Optimizer

    I'm assuming this will make the circuit run richer like the fat duc does.
    Will my check engine light come on, like it does with the fat duc?
    More details, please.

    A little more info please. Does it compensate for ambient air temperature , etc ?

    Re: New to Market - 02 Optimizer

    The optimizer uses a (well tested) powered circuit board vs. a simple variable resistor. It does NOT illuminate the F.I. light as the FatDuc, because (as witnessed on the dyno) the FatDuc put the AFR in off the scale rich conditions within 30 seconds in closed-open-closed loop conditions.
    Dan, all of the compensation still relies solely on the ECU still. Only my full fueling kit is fully adaptive (as you know already).

    Re: New to Market - 02 Optimizer

    Ok, Todd I am in for 1, I will try it on my V7 Classic and I never got a response back about the V11 Sport ECU for the Cal Vin, I have a brand new 15RC ecu if we can work out some sort of swap for the V11 ECU. I am not looking for getting it for nothing BTW. So how do I order the new module ?

    What would be the benefit of this for someone installing a PC-V?

    Re: New to Market - 02 Optimizer

    Hmmm, I sent you a reply. I'll do so again now. For anyone else interested, please send me direct e-mail to order; Todd at GuzziTech.com

    John, with just a PC on the stock 15RC or 5AM ECU, one is not able to revise the fueling below 40% throttle at ALL RPMs. The Optimizer dynamically revises fueling below 40% throttle.
    Unlike my full fueling kit (ECU/PC-V/AutoTune) that provides dynamic revisions to 100% of ALL fueling at ALL throttle positions.

    I only have ~6 (total) custom PC-V's left for either the 15RC or 5AM Guzzi.

    Re: New to Market - 02 Optimizer

    Perhaps you've got the Fatduc dialed to high. Try just getting just "a touch" of correction. I've got a different DIY version (no resistor) and I'm not getting any engine light.

    Re: New to Market - 02 Optimizer

    Got my optimizer today and installed it on the V7 Classic, took all of 10 minutes, Seems to have eliminated what little popping I had because of the Mistral cans. Bike seems a tad more responsive I give it a thumbs up !

    So how if I wanted to go "off road " is the A/F mixture adjustable ? I assume the screws in the black box have to be removed and then what ?

    Still waiting on the response for the V11 Sport ECU.

    Re: New to Market - 02 Optimizer

    Excellent, thanks for posting.
    Dan, inside are dip-switches, I can give you the configuration to go richer. Contact me direct, and I've replied twice to you on the ECU, once including the e-mails about the 02-controller, and the second only the ECU. PM me here or e-mail me again, we'll get it sorted.

    Also, I can re-flash the ECU to give full map access to a PC or PC-V & AutoTune for anyone interested. Contact me direct.

    Re: New to Market - 02 Optimizer

    Hi Todd,

    interesting thing, that O2 optimizer.
    But what is the differrence (if there is...) between the combo O2 optimizer, PC-V+AT and the combo ECU flash, PC-V+AT?
    As I understand, both ways you handle 100% feuling.
    Is one of the two better? and why?

    Thanks.

    Re: New to Market - 02 Optimizer

    The Optimizer offsets the stock (narrow band) 02 sensor-to-ECU signal to crudely* correct the fueling below 40% throttle, and the PC-V would have access above (which ideally would require a Dyno tune). If you add the AutoTune module to this configuration, you would need to weld in an additional 02-sensor bung (into your exhaust) for AT's wideband sensor, which would only be able to revise fueling above 40% throttle, and you'll have two sensors controlling separate parts of the map; I really can't say I recommend this configuration.
    My GT-Rx ECU (WELL covered elsewhere here) deletes the OEM sensor to allow full map access to the PC-V & AT (the new wideband sensor replaces the stock narrow band sensor). The GT-Rx ECU sets a new baseline for fueling (you can run on this alone) and it also revises timing for pre-detonation/ping, cold start and performance.
    The GT-Rx ECU/PC-V/AT is the simplest, most precise, dynamic fueling package available.
    Which can I get you?

    *Narrow-band 02 sensors are more limited than wide-band 02 sensors; i.e. narrow-band 02 sensors can only send a signal to computers indicating whether the AFR is lower or higher than 14.7:1. Wide-band 02 sensors can tell the computer the amount by which the AFR is lower or higher than that baseline AFR. Engineers and performance specialist utilize wide-band sensors when they need precise AFR readings. The more precise the reading, the better engineers can tune and tweak performance.

    A photo or schematic of this installed would be helpful.

    Re: New to Market - 02 Optimizer

    Schematic? Just find the other end of the 02-sensor and plug in line, and ground the black wire to a suitable location. I'll post some pics when you snap some for me. ;)

    Re: New to Market - 02 Optimizer

    It would have been helpful if you'd simply said,"John, pull the starter cover and starter and the plug will be apparent." I also have no idea what the two small sheet metal screws are for that you included in the package. I've sent you a few e-mails on the PC-V install and the Optimizer. Gimme a shout when you have a moment. Thanks.

    John

    I believe they are mounting screws for the optimizer if you have a convenient spot, I just zip tied it on.

    Hope this helps

    Re: New to Market - 02 Optimizer

    I guess I'm a bit of a Troglodite, but where am I going to find the other end of the ox sensor? Is it under the tank? If so, is it nessasary to take the tank all the way off (as I have not tried to do this before) or could it just be lifted a few inches at the back?

    Any help or pics would be greatly apperciated. :blink:

    Re: New to Market - 02 Optimizer

    The connection is hidden behind the starter. On the Stelvio and G8V, you can get to it without removing anything. On the Breva/Norge, it is zip-tied so you have to pull the starter cover (unfortunately), on some I've had to pull the starter. Below is a graphic.
