OK, I have a 2019 Carbon and I would really like to put a PCV on it. I've done this with all of the modern fuel injected bikes in the fleet - get the best flash available to derestrict the secondary throttles, top speed limiter, redline, decel fuel cut, and all of the other stuff, then FINELY dial in the fueling with a wideband and PCV on the dyno and road. With proper effort and attention, this is without a doubt THE BEST possible tuning situation. I don't care how good a canned flash tune is, the fueling will never be perfect EVERYWHERE for you specific setup, and it can often be way off at small throttle openings (cruise) and other odd areas of the TPS/RPM space.

The PCV is only (officially) available for 2015-2016 H2 and H2R models. Why, I don't know? This is per Dynojet's site and all of the other vendors are in line with this. I can't find any record of anyone trying one on another model year.

Well, looking at the installation instructions (which are in line with most other bikes), the H2 PCV works conventionally. It intercepts the signal to each injector and modifies it from a lookup table ("map") according to a couple referenced sensors (gear position, cam position/RPM, and throttle position), then sends the modified signal to the injector. There is no connection/communication with the ECU, it simply modifes the injector pulse according to a couple sensor values and the "map".

The connections for the PCV are:

Chassis ground
Primary injector (throttle) harness
Gear position sensor
Throttle position sensor (main throttle body connector)
Cam (crank) position sensor

So, I looked up all of the part numbers from the fiche and found:

2015-2019 all have the same injector harness part number
2015-2019 all have the same gear position sensor part number
2015-2019 all have the same cam sensor part number
2015-2018 all have the same primary injector part number (2019 different, same connector)
2015-2018 all have the same throttle body part number (2019 different, connectors look the same)
The ECU part numbers change from 2015/2016, 2017/2018, and 2019 (not that this necessarily matters).

So from an installation and function standpoint, I can't see why the 2015-2016 PCV wouldn't work on AT LEAST a 2017-2018 H2 (all connected components are the same), and for that matter, on a 2019 as long as the TPS/connector on the throttle body hasn't changed.

I'm going to inquire directly with Dynojet, but let's throw the question out there - Is the PCV ONLY available for 2015/2016 because it only WORKS with those years, or is this because (due to impossibly small build numbers) nobody has had the balls/interest/know-how to test one on a later model? Dynojet has nothing to gain, as there are maybe 20-30 from each year even on the road, so maybe they could sell another 5 or 10 units (after somehow getting a test mule). It just seems to me like it ought to work just fine, but nobody has ever gotten around to verifying that.

Any input?

Possibly the ecu is smart enough to know its not getting the correct flyback signal from the injectors and gives a fault code
or after the initial release PC have not tested or updated year model list

Well, I contacted a/the prominent tuner AND Dynojet themselves. Surprisingly, got prompt, candid answers back from BOTH within 24 hours. Thanks, guys!

As I suspected, the PCV is only offered for the 2015-2016 H2 because it hasn't been tested/verified on the other model years. Dynojet haven't put their hands on a 2017-2020 test mule (and don't seem terribly motivated to do so given the paltry production volumes) and the story was pretty much the same with the tuner, more-or-less.

I'm rather confident that it will work on the 2017-2018, and I suspect that it will work on the 2019-2020 as well (the only real difference being the change in the throttle body assembly part number). And honestly, even if the pinout on the throttle body has changed, it might be as simple as sleuthing out the correct wire via some "comparative anatomy".

Both entities had basically the same advice - "check it out and let us know if it works". Of course. So I've ordered a unit and will be checking it out, and despite my reservations against doing R&D (and marketing, and sales support) for two/several for-profit businesses without compensation, I will inevitably be reporting my findings here when I find something out.

Wish me luck!

A slight correction - the PCV indeed connects with the crank position sensor (pulse generator output), NOT the cam position sensor. I'm working on the bike now and should know something within a week or two.

OK, gang. I have installed the PCV on my 2019 H2 Carbon (along with a host of other things, including a Van Demon pipe) and I can verify with certainty (tested against a wideband to verify correct operation) that it works perfectly. The installation was 100% according to the packaged instructions for the 2015/2016, no deviations required. This is great news.

So I can safely say that the PCV marketed for the 2015/2016 H2/H2R works on all model years 2015-2019 inclusive, and most likely on a 2020 as well.

This is a GREAT tuning option for those of you just wanting to work on fueling, SOOOOOO much easier, faster, and intuitive than altering fueling via a flash. The killer combination is to use this on top of a flash to just trim fueling here and there (clean up any trouble spots) against a wideband.

I have not verified that any of the other Dynojet modules (ignition, secondary fueling) work, nor will I be doing so. But I suspect that they will work (FYI they are ZX-10R units).

So it works?!
What PCV PN did you end up installing?

Have you gotten it tuned yet? Were there any issues? I currently have the Wollich flash. I'd love to get the PCV on top and if it works, I'll order one this week!

I installed the PCV for the 2015-2016 H2/H2R (PN 17-062). I haven't done any tuning because I am waiting on a flash - I sent the ECU to a (very) prominent tuner over a week ago and have thus far been ghosted, it's pretty weird. Not sure what is going on right now. If I EVER get the ECU back I'll start road tuning immediately - I have a wideband and Dynojet POD-300 onboard so it should be pretty easy. And a good starting base map for the flash/pipe/filer as well. Only issue is safely (?) road tuning a 200+ MPH bike at high throttle openings to redline, scary.

That is the issue I ran into using the Woolich autotuner. It did a pretty decent job tuning the gears and RPM ranges that I rode in the most. But it was VERY difficult and scary to try and get enough time in those upper gear/ RPM ranges to gather enough data for the autotuner to do its thing. When I finally got it onto a dyno, I was shocked at how poor a job the autotuner had done.

Im not an expert at this, and Im sure some of it might have been user error, but if I had to do it again, I would have skipped the autotuner. I really hope you get your ECU back and am excited to see how your tuning session goes.
If it works, I will get one.

Keep us posted!!

Don't know if this assists at all or just adds to the chat, but I had Woolich tuning done on my bike ('15).
Joel the Woolich tuner fitted the Z-Tronic logger, I did a track day and he said to open it up in at least 2nd, 3rd & 4th if possible - it was possible but bloody hell what a rush! - this is without traction control on.

He made some tuning adjustments based on what the logger recorded, but he also did a final dyno run to get all gears and rev ranges in. At this stage on a "conservative" AFR of 11.8:1 he got 262 rwhp. But main thing being the lower rev/speed settings were improved.

I've since added an E.C. Intercooler but yet to take to the track again - he wants me to put the logger back on for that ride, then later do another dyno.

When I began working on my 2015 it was 193 at the rear. I did a Guhl flash to the stock bike and picked up about 30 hp. Don said I did not need the PC, but I did it anyway and picked up about 16 more hp. I am going from memory, not my notes, but the PC should help even with a flash.

have you done any tuning yet? Can you provide some updates. I am still considering this as an option and would like to know if it works without issue before buying one.

Thank you!

I have been very clear in this thread that it absolutely WORKS, 100%. So if you want one, get one.

I haven't attempted to road tune this thing, it is WAY too fast. Need to get to a dyno to do it safely, and things are crazy in this era of COVID.
