    Chris, not sure of the SPAM for them here, but you certainly have a PCIII, not PC-V if you've had it for more then a year, and did not purchase from me. This simply means that you are only revising the fueling above 40% throttle. The world in which you mostly ride is below 40% throttle, so you have yet to discover what the ultimate in fueling offers.

    I have fitted a power commander v5 and autotune module on my 2010 Stelvio NTX. Can someone tell me what the trick is to not have the service warning light come on. Can I just leave the stock O2 sensor plugged in and strapped up somewhere out of the way?
    The autotune comes with a replacement broad range O2 sensor which I have utilized in the original fitting to the exhaust pipe. Is it possible to remove the original O2 sensor all together or should I just leave it plugged in?
    I do know that Todd can reflash the ECU but that is not what I want. I want to be able to reverse the installation at any/some time.
    Will leaving the original O2 sensor plugged in but not fitted in the exhaust do any harm?
    Your help will be appreciated.
    Cheers

    Boneshaker, it's all covered in my PC-V thread in the main section. If you do not use my ECU, you cannot unplug/remove the stock 02-sensor (it'll put the bike into an emergency/limp-home mode if you do) or revise the fueling below 40% throttle, and you'll need to weld in an additional 02-sensor bung for the wide-band 02-sensor supplied with the AutoTune unit.

    Thanks Todd, I have welded the extra bung on. Works a treat. The performance difference is amazing.

    Very good, just be sure to not try to over-ride the fuel map in the PC-V software below 40% throttle. It seems they deliver them with 10% in these columns, I recommend deleting them, meaning making them '0.' I also recommend narrowing the AFR target in AutoTune to 10% +/-, and not accepting the trims after one or two long rides.

    It's still months before I end up in your neck of the wood, Todd (on a tour) but am curious as to the need for the PC and Autotune. Really don't want to spend the money and am hoping that a remap of my ECU will work for me (2012 NTX). I have a Mistral can and have disconnected the canister hoses. And should the O2 plugs be pulled and bunged also :?:

    Static mapping is difficult in trying to blanket one map for thousands of bikes around the world including fuel differences, wear and tear, etc. That said, my ECU re-flash for just a slip-on is very very good. If you are "set it and forget it" rider, then the ECU alone is best... If you are the type of rider who will try to find troublesome spots in the mapping, then I recommend the dynamic PC-V & AutoTune system in addition, as it will auto-revise those areas and give you access to fix any troublesome areas yourself (or via me/e-mail).
    With just the ECU, the sensors should be pulled and plugged (I have plugs here), and of course with the AT-300 we would install two wideband 02-sensors. Other questions?

    Look forward to meeting you one day soon.

    Hey Todd,

    I'm not sure why I didn't notice this thread before... I have a GuzziTech reflashed ECU on my Stelvio that the previous owner added, but he didn't remove the O2 sensor. I'm getting terrible fuel mileage, but the bike has run well - seems a little fat here and there. I've PM'd you about an airbox change I'm planning on making (you responsended) and have been considering possibly going to the PCV and autotune. What are your suggestions - reflash the ECU for opened up airbox and remove the O2, or just move towards the PCV / autotune? I'm trying to be cost effective on the hardware side, but would also like the best fuel economy possible (its a 09 with the small tank), and don't want to loose performance.

    Thanks,
    Jeff

    Reviving an old thread. I am planning to install my new PCV/AT. Are the instructions in the first post by Todd applicable to a
    '15 Stelvio? Also, it appears the pictures no longer work either. Thank you.

    Did you buy the setup from Todd?

    When I bought mine years ago there were printed instructions included I thought.

    I did buy it from Todd. It just has the generic instructions from Dynojet.

    Also curious about pics. I'm contemplating replacing my old PCIII with a PCV on the V11 Sport, and I'm curious about lambda sensor bung mounting and where others may have put those on their bikes. I'd be sort of inclined to have the bungs placed similarly to where the current production Guzzis are - not far from the exhaust port on the top of the header.

    Then Todd’s your go to guy! He’s very responsive in my personal experience.

    FWIW: “Niceness Counts”

    Agreed. I reached out via email and was instructed to check the forums as well, hence my earlier post.

    Yeah, I sent him a PM when I saw your first post and he said he'd been in touch with you and was looking to make some new photos as the others got screwed up I guess...

    Hopefully you are all set now.

    Thank you. I plan to attempt the install this weekend. I'll do my best to document my process and share the results.

    I was finally able to get some time to install the PCV/AT. The bike runs much better in conjunction with Todd's fuel map! I created instructions on how I installed the set-up using some of Todd's language/instructions and some of my own.
