    Help needed. I purchase a power commander v and autotune to use on my 2012 Rocket Roadster. With the help from Hanso (thank you once again Hanso for your help) and a few electrical problems solved. i have the bike running well, although have had the coment that the boys can smell unused fuel when behind my bike. My problem is the autotune will not work with the power commander. I have completed the installation as per instructions, setup the software, but there are no values in the trim tables after a 150km ride or any ride.???? i suspect that the o2 sensor is at fault. Little annoyed after spending big bucks on the setup. Any help much appreciated. Tony

    So what did @HansO suggest? He did my PCV and AT200 set up personally so I am pretty ignorant of it all but there were a few instances of the AT200 plug in cable having a connector issue. Hans had it with his, fixed with a replacement AT200 cable.

    Hi Tony

    I have installed a few of these for myself and other people and have had a few little issues.

    Firstly have you gone into the software with your laptop and turned the auto-tune on? if you dont do this is will not work. You go into the Dynojet Powercore software, select C3 tuning program, select configure and all items plugged into the PCV should show up. Select the AT tab and enable it.

    The PCV light and the AT green light should also be on, check those first.

    In the settings there is also a time setting before it starts i set mine to 5 minutes (is in seconds)

    Lastly make sure its not set to switch to turn on and off the AT (not a good desciption as cannot bring up display without plugging in and going from memory but you should see what I mean.

    Set trims to 20% for a while, accept and reduce trims to 10%, accept, then reduce to 5% and dont play round with it anymore.

    I have recently had a major hassle where my PCV AT savagely leaned out the bike at low revs, this was a result of me accepting the trims too often and always subtracting fuel from down low in the tables. The AT will always try and lean the motor out at these low RPM due to the fuel shot that gets dosed whenever you wrap the throttle round and the AT trying to "correct" this, have a read of the post I put up recently and Penner and Clavigers explanation re this.

    I reset the base map and have started again issue solved.

    So what's the benefit of having the PCV, over just using TuneECU ?????

    Hi Cooter

    Only really any use if you also use the Autotune Wide Band O2 sensor. My experience over here with Dyno tuners has left a lot to be desired so far, so this has been an benefit.

    It can only change fueling by targeting set AFR's and cannot do ignition adjustments.

    The best would be dyno tuners that can competently work with Tune ECU but the closest one I can think of is in Aussie, if there is someone in NZ I'd be keen to speak with them.

    If you can find a good tuner that's willing to try using TuneECU, I'd talk to them, and see if they'd be willing to give the bloke in the tin shed a call. I'm sure half of the Rocket owners on your island would benefit.

    Please do read my post on using the AT module, it’s not as fool proof as it at first seems.

    PC-V benefits include:

    Being able to “over provision” you injectors. Normally, using TuneECU or TuneBOY you’re limited to 80% duty cycle. That’s normal in the industry to ensure longevity.

    With PC-V it will let you input values high enough to hold them open 100% if required, this how you can run stock injectors on the Carp 265 package, a low boost turbo setup, or low boost SC setup.

    Another benefit is that you’ve got a computer that nearly any tuner is farmiliar with. Very few will work with TuneECU or TuneBOY.

    Additionally you then have all the more advanced items in the PC-V ecosystem like: Quickshifter, Ignition Module, POD-300 etc.

    You can then have live high rate dataloging, a temperature gauge, etc etc.

    The PC-V can be used to tune a forced induction bike using Pressure vs RPM tables instead of TPS vs RPM tables. The advantage is that for a turbo setup, TPS vs RPM is bad because 40% throttle at 2000rpm in 2nd gear might only build 5 PSI but in 5th it might make 7 PSI, so you need pressure vs rpm not tps vs rpm.

    Also, tuneECU is balls to work with, PC-V software connects instantly, reads and flashes 100000x faster (lol) and you don’t even need the ignition on to update your tune. Plus you can make some gross adjustment even without a computer if you have a pod-300 on the fly.

    I used to think the PC-V was a waste when we have direct ECU access, I’ve since come around and realize it’s much better to load a good base map and then make adjustments using the PC-V.

    Is the Auto tune a good thing to have or is the PCV good enough by itself.
    My friend said what I just read on another post, the AT will lean the bike out if you leave it turned on. I've used tunEcu but I want to get the bike dyno tuned and the guy is familiar with PC not tunecu. So, I'm contemplating buying one but wondering if the auto tune is worth it. Thanks for any info.

    The AT is not necessary if you have someone who will tune it for you. The AT is just to adjust the tuning if you aren't getting a custom tune.
