Maybe it helps to make things more clear for each of us if we take a look at my options:
Option A: Do nothing more. So, leave my DP "racing EVO" ECU stock, leaving the Lambdas with Powercommander o2 optimisers to continue to manage in the closed loop. Run with the WASP created "off-the-peg" PCV mapping. The bike runs well like this (although I dont KNOW for sure exactly how well the WASP PCV mapping is matched to my particular setup). For that I'd need to go to Option B.
Option B: (Now abandoned) Was to leave my DP "racing EVO" ECU stock, leaving the Lambdas with Powercommander o2 optimisers to continue to manage in the closed loop. And put my bike over a Dyno to create PCV custom mapping for the open loop area.
Option C: Reflash ECU to remove o2 inputs thus deleting the closed loop. Dump redundant stock o2 sensors and "optimisers". And put my bike over a Dyno to create PCV custom mapping over the ENTIRE range.
Option D: Reflash ECU to remove o2 inputs thus deleting the closed loop. Dump redundant stock o2 sensors and "optimisers". Figure out how to adapt the PCV dual wideband o2 Autotune option (version AT-100) to build dynamic custom mapping.... over the entire range.
Option E: Reflash ECU with Rexxer-written custom tuning map, based on their best estimate of whats needed to fuel my WASP intake mod and Termi exhaust combo. Dump redundant stock o2 sensors and "optimisers". Dump PCV. A tidy solution, but no way to measure the outcome without visiting a Dyno. And then - unless Rexxer hit it perfect first time - I'd need to go back to Rexxer to ask for ECU mapping to be modified based on Dyno results. Could take several Dyno visits/Rexxer remapping to get it just right.
Not available to me, but for those who live in Europe there's also another option:
Option F: Visit a Rexxer Tuning Centre and have them reflash the ECU with a custom tuning map created using their Map Editor software based on their Dyno results for your bike. This IMO would be the best option of all, after all what you would end up with is an open loop ECU mapped for optimum performance for your setup. No "piggy-back" PCV.... No o2 sensors...
This process is not that different to the PCV tuning session you'd get at your Dynojet centre EXCEPT that Rexxer are "tuning" the ECU mapping directly, rather than modifying the ECU mapping though an "add-on" unit.
Seems that for
me the most sensible options are either Option A (after all its already fabulously better than stock)..... or to go to the next level, Option C. But being sensible is not always what motivates me. I wanna know if I can make the Autotune setup work, I like the tune-it-as-you go, user-inclusive modability this seems to offer. I believe it can be done and so its as much about the process of finding out how as the end result. I know. I'm my own worst enemy
.
Whilst more of both is always nice, I'm not chasing peak HP.... or max torque... or any big raw number. I just want to acheive the best overall result for my particular setup. The gain will be most likey in the
how it does what it does rather than doing any
more of anything I suspect.
