Have the PCV with auto tune on my 2011 RGU works like a champ.
Better instructions would of helped. And also for my bike the angled o2 sensors would have worked better. Then the straight ones that came with the kit.

Not worth the money
Install was cumbersome with quick connector located close to the exhaust instead of under the seat, multiple wires to connect to the autotune itself. Adjustments made by the autotune differed greatly from the other maps and caused surging, sluggish response, etc. While I am not happy about the hours and money spent on the dyno, this has not been the alternative I was seeking.

great product made
This kit allows those who do not wish to pay extra expense for a mechanic to do so when climate in home town changes. This item will do the full adjustment needed to run great in any condition every time.

Dynojet needs to go back and test this on the FZ1!
When I got this, not only was the 02 sensor cable too short with a too-large connector, but the product was a disaster. I had a great map that I wanted to fine tune and maintain with this Auto Tune. On the FZ1, this product is a disaster that caused poor gas mileage, lean surging, and generally poor performance. I took it off after two months of calls and emails to Dynojet, who in turn acknowledged lots of problems on bikes like the Vmax, R1 and FZ1.

Works Great!
I've read of others having problems with the Autotune Add-on for the PCV. I had no problems. The install was on a 2009 CBR 600RR. I installed everything as instructed and did not run into any problems. I did install a switch to allow a base map and learning mode for the autotune. After the first run, I was sold. The bike is running so smooth, the purchase was worth every penny. Do keep in mind, in order to tune completely, you have to run the bike at various rpms and throttle positions for a full tune and the autotune will take samples and make the trim table. My opinion of a autotune vs a dynotune in reality is a hands down for the autotune as it makes adjustments based on real world conditions such as ram-air, ambient temp, traction, etc... Just my 2cent. Bottom line, if you are a diy kinda person, I would definitely buy one. If you're not and just want the bike tuned, then I would suggest a dynotune.

autotune zx14
I love the product, but Dynajet needs to redo the instruction sheets. Maybe more specific to the model, and try to improve the location for O2 sensor plug. Not much room where they expect to go. Still a great product and like all aftermarket equipment, it always requires a little finesse to install. I recommend this to all interested.

A lot more work then let on.
I have a 2009 CBR1000RR with the Yosh R77 slip on with the PCV and I ordered the Auto tuner. I was super pumped to receive it until I opened it up. The directions suck and the O2 sensor that comes with it is an 18mm. All sport bikes with O2 sensors use a 12mm so you have to drill a new hole in the exhaust and have the plug that comes with it welded in. It would have been cheaper to pay for dyno time and a custom map. Very unhappy! Customer service at Dynojet was not very friendly either. The guy I talked to told me I was not the first CBR owner to call and I wouldn't be the last.

Power Commander Auto Tune
I purchased a New PC V and Auto Tune for my 2010 Triumph Speedmaster because I had used the PC III in the past. The PC V installed in a flash just like my PCIII did but the Auto tune was a different story. First thing I noticed was the O2 sensor was a different diameter and thread than the stock ones on the Speedmaster. The stock O2 sensors are 18 MM and the ones that come with the Auto Tune are a lot larger. After trying to figure out how I was going to drill, and weld on the bung that came with the new sensor I gave up. The double wall pipes would have to have been destroyed so I packed the Auto Tune up and sent it back. No hassle and the PC V seems to work just fine without it. Power Commander will have to come up with an O2 sensor that's 18 MM to make this work the way it should. On my previous bike (an FZ1) the O2 sensor was the same size.

Another Great Tool for the Power Commander
The Auto Tune is useful to folk who want to do their own tuning and make their own maps for the Power Commander. You must either take your bike to a dyno tuner or buy the auto tune so you can make your own customize air/fuel ratio maps. If you make modifications you need to retune the bike. With the Auto Tune you do it yourself rather than taking it to a shop each time you make a change. The Auto Tune allows you to monitor the changes the PC is making to maintain the air/fuel ratio maps you install. This is a must have for Do-it-Yourself people.
