Ok, but to cut down on the confusion, it would probably be best to discuss non-PC V topics outside of this thread. My very specific comment was: If someone is getting a PC V, in my opinion, getting a Autotune module with it would be a good idea.
I personally wouldn't want one without the other since my rides usually start at sea level, hit 3-4000 ft. and back to sea level again.
Installed. Bit of a mission though, trying to get the plugs through the gap between airbox and tank, and then trying to push hard enough for the clip thing to clip in on the throttle sensor. The thing cruises at low speed now, no more jerkyness and missing, it just putts along nicely and is more responsive now There is something going on though with what I think people have called a 'hanging idle' where it seems to take a while to drop down to idle after throttle off. Kind of annoying. Surely a map or something will sort it.

The stock ECU would take care of the altitude change. I doubt, or at least hope, the the autotune does not correct for altitude. It's purpose is to get a good tune on the bike. Once that is accomplished, the ECU itself will take care of things like temperature, air density, altitude, etc.
The PCV installation requires the removal of the stock 02 sensor. even if you don't install the autotune which has it's own O2 sensor. Thus, the stock ECU can't adjust for elevation changes, or any other closed loop stuff because it's forced into open loop by the removal of the O2 sensor So, the autotune does correct for altitude. it's purpose is to *maintain* a good tune on the bike, in real-time under all conditions.

Interesting. But shouldn't a PCV without autotune also compensate for altitude and other changing conditions?
Without the stock O2 sensor there is no feedback to the ECU, so it cannot tell how rich/lean the exhaust is. I was surprised myself when I saw the PCV instructions say to disconnect the stock 02 sensor, regardless of autotune installation. I guess dynojet just uses the stock open loop map, and modifies that. (unless you install autotune as well, then the 02 is read from the exhaust) You can run more than one map, if you chose not to install an autotune unit, and have a switch to manually change between those maps. as far as I can tell, there's no way the PCV alone can compensate for altitude changes. I'm not even sure if the bikes ECU takes ambient air temp into account in it's open loop map. perhaps someone who knows can chime in. --Chris
Mine too! My dealer is removing my ECU and associated equipment to send to Husky who says they will use their Moss tool to try and fix the issue. Apparently, these things have to be very lean to pass emissions testing but there are some with problems and some without so I'm hoping there is a fix. I'll let you know when my stuff is back from Husky and on the bike.
Please forgive the dumb question but will installing the PCV alleviate the need to have the bike "MOSSED?' Thanks, Craig
If it does take into account ambient air. The temperature sensor is in a bad location pretty much reads the wrong temperature and does not adjust very quickly. Notice this morning in 70 degree weather it read 80.5 and then flashed between 77.5 and 80.5 twice but never stayed under 80.5.
Not as far as I am concerned, no. Though it will quite probably run better. Not sure because I did not put a PCV on my TR650.
Just wanted to put in a plug for REVZILLA as a source for Power Commander V and Autotune and here's why. I bought both from REVZILLA, getting the PCV first then the Autotune about 3 weeks or so later. I finally got time to install the stuff another 2 weeks at least after receiving the Autotune. Drawn out process but all due to budgets. So all in all, almost a month from receipt of the A/T. Anyway, I finally got around to installing the PCV and the following day went to install the Autotune. Doing my homework, I read up on the PCV thread here about install and I was fine until I read the part about finding a power source for the A/T. Huh, I thought, power for what? Then it dawned on me. This is for the A/T module. Did I get one in the box?? I remember seeing the O2 sensor and wiring which I already installed but where is the module? Has to be there I thought, just didn't take notice...Went to the garage, looked everywhere. Finally after day 3 of looking, I realized that , hey, I just did not get one. I Called REVZILLA up, explained to them what had happened, and with in 48 hours they replied and are sending me a replacement module and all with an apology for the inconvenience. ( I know they called Dynojet and did all the leg work so I applaud Dynojet for standing behind there product as well). Given the amount of time that went by from purchase to install, these guys were still willing to honor the purchase with what I feel is some incredible customer service. Not only do these guys(and gals) have great prices, they are committed to a level of customer service that is hard to find these days. Can't say enough about them, highly recommend them for all kinds of bike needs. Give them a look at REVZILLA.com. Thank you REVZILLA!!!
I agree with Toyboy Revzilla is a great online site that does care about there customer service. I have spent close to $2k with them getting all my riding gear all over since I have not been riding in 10 years and now I ride everyday good or horrible weather.
I've bought several PCV units from FuelMoto. They are the nations largest distributor of DynoJet products and they have the best prices ($110 under MSRP right now). They also have great customer support and will help you develop custom maps if needed.
