so i finally got my PCV and started to install it last night and have some questions for those of you that have done it or are otherwise in the know. I searched the forum here so hopefully i'm not repeating something that has been covered.

-my first question is to verify that i installed the injectors to the correct ones. the instructions say that they are marked #1 & #2 on the stock harness but they aren't on mine so i just looked at which one went where and it looked like the back injector plug goes to #1 and the front to #2 since they face toward those cylinders. is that correct?

-i'm installing the auto tune which replaces the stock o2 sensor, the PCV comes with a o2 Optimizer which plugs inline with the stock wiring. the auto tune plugs into the new o2 but leaves the stock wire disconnected. do you just leave it disconnected and toss the o2 Optimizer?

-the Auto tune has a wire that needs to connect to a switched 12v source. does anybody know where a good wire to connect to is?

-last.. why did DynoJet only supply a Windows program to run thier software?? this sucks for anybody that has a Mac laptop. (nobody really needs to answer this)

thanks for the help.. i need to ride soon


<<<<<<<<<<<<<<<< Update >>>>>>>>>>>>>>>>

I finally got to take it out for a ride and it runs pretty good now, although i'm not doing wheelies over diesel trucks like i planned. Anyway i thought i might answer some of the questions that came up while i was installing it in case someone from the so called Future, like if Marty Mc Fly, shows up in a De Lorean or some other failed luxury sports sedan. Some of the questions are answered by people on this thread but here's the summary;

Plan on Welding in a second O2 Bung (for the at200, 2 if you get the dual.. thanks to mikoloe for crushing my hopes of an easy install ;) ), you'll need both the stock and the wide band one that comes with the Auto tune. I had a muffler shop do it for 10 bucks. I have the V&H twin slash staggered and there is a spot on the upper pipe pretty much in line with the stock o2 on the bottom, clearence is tight with about 4mm on each side so measure good, i had to grind a little bit off the heat shield to make it work but it doesn't look bad if you do a good job. i also had to cut a small notch in the black cover that sits under the side cover.

i used the rear brake running light wire for a 12 volt source, its easy to find. It should be a blue one but check it first.

finding a place for the PCV, Auto Tune, O2 Optimizer and the o2 wire connecter (its big) was a pain. I have the Low and Mean seat which reduces the space under the seat. if anybody from the so called future wants to see how i did it get in touch and i'll snap some pics.

once you have it installed you'll need to make sure that the little black terminator plug is installed in the open port on the auto tune, download a map off of dynojets crappy website, plug in your windows based laptop not your mac because dyno Jet hates Mac users and want them all to screw off and go to **** (ok, maybe im being dramatic), then upload your map to the device, then enable the auto tune. there's a little light that says if auto tune is running or not that won't light up until its actually doing something. I spent some time trying to figure out why it wasn't running. if you see "2 devices connected" in the lower left it should be working, while the bike is running and after 60 seconds. there's some youtube tutorial videos that are easier to find than dynojets site.

if i was to do it again i'd probably just have gotten the EJK but it looks like the PCV will be more tunable, yea right.. trying to justify the nearly 500 bucks spent. Also i'm sure once i figure it out i'll be jumping canyons and ****.. and not bailing out like that puss Evil :0

thats all i got for now,

Leave the stock o2 sensor plugged to the optimizer. You will need 2 new bungs istalled if you have the dual wideband auto tuner.

back injector plug goes to #1 and the front to #2 since they face toward those cylinders. is that correct?
Correct.
i have the single wide band auto tune (AT200), any idea on that one?

good to know that i installed the injectors correct, it was tough getting my fingers in there i don't want to do it again

i got the answer on this:

Usually the tail light is a good voltage source for the Auto-tune module. If you can locate your tail light electrical connector. Try testing the voltage on a BLUE wire or perhaps a RED/WHITE wire with a test light or volt meter. You are looking for voltage (12v DC) that turns on and off with the key switch.

Answer to the o2 question for anybody else that might be doing this;

the new o2 sensor has to be added in addition to the stock one.

official reply from Dynojet after clarifying that both are needed:

You actually could use the “dual channel” AT-300 Auto-tune kit that uses 2 Auto-tune wideband O2 sensors (1 in each pipe) on your 2 cylinder model. This provides fuel corrections to the 2 cylinders independently of each other. We found that the Stryker’s 2 cylinders run so similar to each other that, doing this does not give a major benefit to performance. The single channel AT-200 will work fine adjusting both cylinders based off of the O2 readings of only 1. You can also put the single O2 sensor into either cylinder head pipe.

In my opinion, it would probably be aesthetically less of an eye sore if welded into the rear cylinder so that the sensor is pointing inward of the bike (clearance could be an issue here) and not sticking out of the exhaust at a point where it will be regularly seen. I would try to mount it as discreetly as possible, while also trying to get it as far upstream as conveniently and aesthetically possible.

Did Dynojet say to use the stock O2 sensor with the auto tune sensor before the reply that you posted? The reason I ask is because the reply you posted talked about one or two O2 sensors (dual or single channel), but nothing about the stock sensor.

Basically i asked the question if the stock o2 sensor can be left out. they responded with about a full page of what you would have to do to leave it out which was a big technical and expensive sounding process. so i responded "so in summary i need to keep the stock o2 sensor and weld in the new bung to add the auto tune o2" his response "Now you have the right idea."

here's a summary from the info i got from Dynojet

Connect the o2 optimizer (comes with the PCV) to the stock o2 sensor.

Weld in the new bung from the AutoTune (AT200) and install the wide band o2 sensor (from AutoTune)

Anyway if you are in process of doing this i hope to have mine up and running this saturday, i can let you know if worked or not before you start drilling, welding, cutting and cussing.

GEEEEEZZZZZ! So you have to pull the exhaust and have an extra bung welded in just so you can run a tuner? Yeah that's crazy I'm definitely going with the EJK Tuner
yea.. i was thinking last night as i was doing this that i wish i would of taken your advice and got the EJK, it might of taken a little longer to tweak the tuning but the install time(and $$ savings) would of made up for it. A buddy that works at a bike shop and has raced most of his life suggested that i get the Dynojet. live and learn.. then forget.. then relearn. then forget.. and so on. But, on the upside, i was told that after i get it running with the PCV+ i'll be able to pop wheelies over diesel trucks and easily jump the Snake River Canyon.. without a parachute. and thats before breakfast

hehe, did they tell you that after you get the autotuner installed, not the PCV, the autotuner....you will need to get a custom map? no the one you down load from the site but your very own custom dyno map... even then you might be able to do some donuts...

Smoke and mirrors baby! smoke and mirrors...


And yes, leave the stock 02 sensor plugged.

you will have 3 bunges for the dual wide band 1 stock 2 you have to weld
or you will have 2 bungs for the single wideband. 1 stock 1 you have to weld

reach deap, you have to put it on a dyno next

nope they didn't tell me that. as far as i understand you download the map (from your PC laptop, that i don't own, not your mac laptop.. F'n A) then turn a switch on to enable the Autotune.. and BANG! the magic happens. donuts, wheelies, crowd pleasing jumps and rich supermodels throwing themselves at you. God i can't wait

Evel knievel jumped a canyon once didnt he?

On a serious note, i hope it works out for you.

Here is a question, the guy or guys telling about this, do they own one?
yep he tried to jump the snake river canyon but it was more of a rocket than a motorcycle and the parachute opened to soon so he didn't make it.. he use to be my hero until the rocket thing.. he kind of pussed out. i tried jumping my swimming pool on a crappy BMX bike when i around 10. i didn't make it but it was way before Dynojet had the PCV so i'm pretty confident now.

the guy that recommended the Dynojet races Hondas also we race shifter karts and he's been pretty knowledgeable at the track, plus i was getting so many conflicting reviews that i went with it. I'm still trying to hold back judgement until i hear it run and feel how it rides but so far it's been a little more work than expected. but at least its raining out here so it's not killing me

I spoke to dunno jet also about this process. They told me that the map they give you is close and should work well. If I had problems to call them with specifics such as where and when the problem occurs. Is it low speed chugging, flat spots, missing, starving for fuel etc. they said they could tweak the map and resend it to see if it helps. At the end he did say the best way is a custom map on a dynojet that way they can tune it to your bike. They told me as they do more tuning with this bike and different set-ups then more maps will become available. I raced super bikes for years and my personal experience has always be good with their products. Yes they are expensive and do create some work but the bikes always ran great once it was dialed in.

I was thinking of going this route. I would like to know how it works out. If not this way then I will either get it dyno tuned or go with EJK. All info is appreciated.
