Dynojet Power Vision AutoTune for Advanced Users

[@7heRedBaron]

This is one of the best vids on Power Vision yet. I have had a Power Vision on my Super Glide Custom for two years. The most important point is to keep saving off the tune to a new slot AND Autotune the newest tune when Autotuning the next time. After making mods to the intake and exhaust, the bike ran terribly. In the first Autotune session it ran even worse. But after saving the tune and continuing to build on that by Autotuning the newest file, saving it again and Autotuning from that file the next time, the bike is now absolutely awesome. Do this a dozen or more times until you get the results you're looking for. Transfer the unit to your PC and save all the files to keep a good record of what was done. Then you can delete them from the Power Vision to open up the storage slots without actually tossing them out permanently. Power Vision may cause you to think twice about trading your bike in or spending big time on expensive upgrades to the engine.

7heRedBaron That seems strange that it would have to go through the AT sequence more than once to get to optimum performance, although I get what you are saying about it improving each time you over ride the newest tune, and I like that idea. Definitely going to try it as soon as new pipe and air cleaner arrive. It just seems that with this type of advanced tech it should figure it out the first time.. Only had it on the bike 1 day, but I already love this product.. Thanks for your helpful input..

[@7heRedBaron]

I don't understand all of the whys. There are other tuners by other designers that work in different ways. Some instantly. But this one creates a permanent map that is written into the bike's computer. If you sell the bike, the tune goes with it even if you want to keep the PowerVision. Or, if it gets damaged somehow over the years, the bike is still tuned in concrete. This is a feature I really like. GL

[@Level20HT]

Very good information that is not covered well anywhere else I have seen.

[@user-th4sw1tc8k]

definitely the BEST video on this subject... thx

[@walkerjw81]

Good video. I just got my AT-120 in today. I'm glad you made this video. Question, why does your tuner have eight custom tune slots and my PV2 only has six?

[@ChrisSmoove77]

Thank you for explaining scale vs cap

[@LSHD254]

very helpful

Will this power vision screen work with PC5 on a 2006 Turbo Suzuki Hayabusa? My stock gauge cluster is Deleted because of the intercooler mounted behind the headlight. Which negates the ability to remount my stock gauge cluster. I need something more slim line

[@Slow10R]

Can a tuner utilizes the dyno O2 sensors to data log ? (Instead of the auto tune wide band sensors). ?

[@voodoodad]

When i attempt autotune, the screen never turns green or displays numbers as in your video. Does this mean its not working?

[@adipranatraktor8535]

just curious, How fast does this autotune read and change while bike on run/race? 1/1000 sec? because human reaction as fast as 1/200 sec.

[@Harleyrosnaestrada]

Hello. I buyed a Dynojet 3D for Road king 2021 bike but when i tried load the program is showing a message like: To enable Tuning, please contact your dealer for licensing information. Could you help me please solve that?

[@lulem400]

I've heard that when in autotune it will only log around 10 minutes of data. I haven't done a lot of research on this and was curious how long an autotune session should / does last? I was also told that you should try and keep a steady rpm range while running one autotune session. (This stems from the guy claiming an autotune session can only hold around 10 minutes of data.) By this I mean you should focus on one riding style such as city for one session (lower speeds and rpm ranges), country (mid range speeds and rpm), and highway (higher rpms and speed). I am going out to try out the autotune feature in a few minutes and might answer my own questions but would like to know for sure. One last thing, why wouldn't the PV just come with the hardware to autotune it correctly using wideband sensors? I know the obvious answer is because buying it separately is more money for dynojet.

[@tyee4u]

***** curious how your tuning is going? Just installed mine and going through the paces... pretty simple so far but installed on a basicly stock electraglide. New 2/1 header and AC coming next week..

[@lulem400]

tyee4u I bought my tuner from a guy out of ohio where I got my pipes from. He had Dynojet pre-load a tune on it for my pipes. The pre-loaded tune had my bike running well out of the box. Ive gone through 3 autotune sessions now and feel it did help tweak the original tune. One thing I am confused about is when I am autotuning I am getting very few values to turn red, most of them stay yellow and not sure if this is getting a good reading or not? I am still using the stock O2 sensors too.

[@PanchoRob]

Is auto tune available on PV4 ?

[@antmrod5198]

Hi. Great video, absolutely great help. I own a PV for my 2012 FLTRXSE CVO. If you allow me to ask 2 questions, for my specific case: 1) when you're doing an Autotune session and have to stop your bike for some reason (get more gas, police, heat, etc...), what do you do before turning the ignition off, but still want to continue with the AT process afterwards? 2) i went from an 19'' front wheel to a 23'' one, so, what would be the advised Speedometer calibration value to have? Thank you so much and please keep on doing a great job.

What is the autotune accessory hardware?

Chris. What is the autotune hardware accessory? I have a 2019 HDSGS with full performance exhaust and 18MM O2 sensors. I would want to use the pro tune option. Thanks

[@RichardGee9]

Thanks for the video. I have questions I hope you can answer: What is the result of Scaling vs. Capping? I have a 113 cu. in. engine with cams, heads, exhaust, larger fuel injectors. An AutoTune, even under very mild demands, always results in cell values exceeding 127.5. Thus far, I have been capping. What happens if I Scale the values? Resetting Trims: Are “trims” the values the ECM learns from riding the motorcycle? As I run subsequent AutoTunes, do I want to Keep trims or reset them? I am running AutoTune Basic with the stock narrowband O2 sensors.

[@DynojetResearch]

[@b6343]

How long should you be riding on autotune? Is there a minimum?

[@DynojetResearch]

This totally depends on how far off your current tune is. The Autotune will make changes instantaneously when the RPM and throttle are steady. If you are constantly varying RPM and/or throttle position it will take longer. We recommend making marks on the throttle tube at each throttle position that correlates to the PCV software (10,15,20,40,60,80,100). Then go out and at a low RPM snap the throttle to said position and hold it there until you reach peak RPM (if possible). Do this 4 times for each throttle position and you should be pretty close.

[@OmarM8055]

Do You suggest to do "SCALE " or " CAP " ...???

[@DynojetResearch]

When using the AutoTune process, the general rule of thumb is to scale the first time you see the message asking if you want to cap or scale. After you have scaled one time, you will want to cap any further auto-tune sessions. Please email us at [e-mail] if you have more questions. Thanks!

[@christiandegall1703]

Hi, Your explaination is certainly great, but I just feel sorry there is no way I can have this translated in french. So, for now, I can't use my Dynojet power Vision ......

I can’t get my bike to learn anything, everytime I ride I check and it shows 0 cells hit and 0% learned. I have the power vision and the auto tune deal there that plugs into the o2 sensor. Not sure what’s going on.

Is it better to cap or scale?

[@DynojetResearch]

Typically you will want to scale on the first Auto Tune session, but then we recommend capping on any further tuning unless you go into the tune and see where it is wanting or needing to add fuel. For more information, you can contact one of our technical representatives at [e-mail].

You can use a Power Commander with an Auto Tune or a Power Vision with Auto Tune, but not Target Tune.

When will you guys fix the spark tuning ability in the autotune pro? My understanding is it will only retard timing not advance it.

[@GenerationGap69]

How do you decide between scale or cap when VE readings are above 127.5

[@thomasmarchese2808]

Wayne Rivett frontman what I understand. You can’t get over 100NA. If you’re boosted and go over 127.5 you would want to scale everything to that to average it out basically. Tuning to a specific boost pressure. But. For an NA motor. You’re better off letting it do it’s thing and capping. It at 127.5 because you won’t get there. Well I supposed you could with crazy cam(s) and head work. But again that’s my understanding. Don’t quote me.

[@dynahack505]

Late response but it depends on how many cells are at 127.5 if it’s 1 cell you would want to cap because scaling with change the entire table versus a couple cells.
