Power Vision Auto Tune is now a reality

This is hot off the presses.

DynoJet has released the autotune software for the Power Vision! You can use your stock O2 sensors or wideband ones.

This is great!

Brilliant!

Unfortunately the V-Rod already has a SEPST and the Softail doesn't really need such a sophisticated answer, but for anyone wanting to get their bike running right this really looks the canine's gonads...

Very nice, finally no computer needed at all. Before you still needed to put your data log in to the computer software to calculate proper changes and than back to the PV than flashed to the ECM. Now all that is done by the PV. I think this is the best and easiest tuning solution available now, pricey though.

Hmmm.... I wish I knew if getting something like this would really pay off with my current setup. Bike seems to run great as-is. But then I don't have anything to compare to.

What do these PV units run a fella?

I don't mind using a computer - what I like is the combo of autotuning and an ECM flash. Before your choices were aftermarket ECM (too big a change for my taste), autotuned piggy back controller (another thing to go wrong) or manual tuning (hard work).

This is the best of all worlds.

I have a Power Vision for my Road Glide... now I have to find a windows machine so I can get the update and try out the auto tune.

If order, what exactly do I need? I get stuff from the US and have it shipped to Portugal via the UK, and that takes forever, so finding you don't have a bit you need is a bit of a bugger...

I have a 2009 Softail. I also have two wideband sensors attached to Deutch connectors from my Twinscan kit. I do want to do wideband...

You just need a Power Vision. Nothing else is needed. Then you'll have download the update if it isn't in the new one.

It works with the standard and wideband sensors. I'll probably get some wideband at some point for the Glide.

Trying to find someone locally who has a spare laptop I can borrow. I only have a Mac at home. I can't wait to try it out.

Unfortunately I do not see the advantage of doing the "Basic" version with the OEM narrowbands other than viewing a wider starting range. The Basic will still maintain the same 14.7 AFR that is tuned for by the factory. Not exactly what you want for power tuning or cool running engines. It does look good on paper though.

Ok, please forgive the dumb questions in advance:

First, are all wideband O2 sensors one size fits all? i.e. will the "wideband" sensors fit on a 2012 Muscle, or do you need to do something special for the red-headed step child?

Next, do you have to leave the PowerVision on the bike? I'm a little confused how this works-- do you hook it up, go for a ride, and then take it off or does it stay there forever-- mind that I'd simply like to "tune and forget"-- I really don't have any interest in continually playing with the tune on the bike. I'd like to tune for max performance in the real world (i.e. not max numbers on a dyno).

Is there a procedure for this to go through all of the performance envelopes, i.e. open/closed loop, wot, etc? after you install the AutoTune? How would you know when you have a "good" data sample? A ten minute ride? a quick blast to max rpm in every gear? Two weeks of data sampling?

Finally, how would this compare to the more traditional approach of a tuner using a TTS Mastertune? Especialy if I have no intention of changing the bike out (except for cams when it's off of warrenty).

Oh-- would it work with cams? I know the PC-V doesn't play nice.

Fwiw, I'm only looking at a Tab pipe with 1 3/4" baffle and the amsoil filter with topless as my setup.

Thanks all-- and I again apologize if these are obvious questions, but I think that the autotune function may make this into something different than it was?

Part II: After trying to make sense of this on the DynoJet website, I understand that I'd have to get 18mm O2 ports welded in place of the stock 12mm ports on my exhaust, and that I'd have to disable Closed Loop functioning.

How do you do that? (Or does the PV magically do it for you), and what is the downside of doing so?

Thanks, and again apologies-- I's trying to make myself smart on this since this may be the direction I want to go instead of the TTS.
