See the sample picture below. It helps illustrate the "tunability" (DISCLAIMER: not posted as a recommended map to use; for illustration purposes only).
The ability to tune across the broad range (rpm vs. throttle position) can really help improve smooth throttle and needed mapping changes. If you're lucky the Dynojet map will be close-- for your application and elevation. The stock Dynojet PCV map did a decent job of improving smoothness and mapping for my stock '11 V, but felt flat (or lean) in a couple of areas (via seat of pants dyno) for my 2011 Versys. After looking at the map chart (for 2006-20011 Versys/ER6N/EX650), the areas I sensed as flat were in fact the areas they leaned the most. So, I'm making incremental/linear adjustments to find a sweet spot. I'm not using autotune, but can see where it could help it be easier to fine tune a map to your bike.
Since you're inquiring about the 2015+ model, the following info won't apply. I did a lot of reading prior to buying my PCV. I think there is room for improvement in the maps DJ offers, for Versys stock condition. Observation: DJ offers a PCV for 2006-2011 Versys/ER6N/EX650 and another PCV for the 2012-2014 bikes. The issue is see with this is three-fold. One
, the Versys prior to 2010 utilized similar ECUs and mapping. Two
, the Versys from 2010-2014 utilized identical ECUs and mapping (same OEM part #), as with the same throttle bodies, wiring harness (2011-2014, excluding ABS models), coils. Three
, I'm very confident that none of the Versys ECUs are direct interchanges with either the EX650 or ER6N. This begs 2 solid questions to seek understanding. (1) Why would the same PCV maps be offered for the Versys, ER6N and EX650, when their original mapping/tuning (i.e.- cams) is different? (2) When the 2010, 2011, 2012, 2013, and 2014 are functionally the same, why would DJ split them into 2 different products (i.e. 2006-2011 and 2012-2014)? Remember, for the 2010-2014 Versys their ECUs, wiring harness connections, throttle bodies, and coils (main elements to operate) are identical, as based on part numbers. And, the PCV maps are different for each of these DJ products (i.e. 2006-2011 and 2012-2014).
That said, if every year model Versys was dyno-tested, I don't see why they would recommend a different map for a 2010 & 2011 vs. 2012-2014. They are functionally the same...more so than a 2009 vs 2010. Food for thought.
NOTE: This isn't a slight towards Dynojet; I appreciate them offering products for our bikes. Though in making a product available in mass production, to varying markets/customers with similar (but not exact) needs, it would only seem logical that that they would minimize production costs and overlap products where applications allow-- as seems to be the case with EX650/Versys/ER6N PCV. I would just like to see specific maps offered for each applicable year model. I think I'd be even more pleased with this product-- Day 1 of installation, and throughout the use/ownership of it.
Interesting. I looked into a product, which I think was Power Commander, and it specifically had blanked out the map below about 3k rpm with a note that it was due to federal emissions regulations and it was illegal to mess with it. That was about a year ago. Dunno.
