Power Commander piggy-back on Termi ECU ???

[SpikeC]

 My first M1100S had LV slipons and stock otherwise and it ran quite nicely.

I had decel popping on occasion even after installing the PCV, but I found some blow by on the junction with the cans. I took them off, cleaned them and put Permatex Ultra Copper, let is cure the 24 hours. seems to be holding for now and no more decel pops, bike is sounding solid! So yes, as was mentioned, it is sucking in air on the exhaust somewhere.

Could be, but the Evo has less under tank space available due to ABS.

Swap out the battery with a Shorai from MonsterParts and you'll have plenty of room

Yep, certainly there is space to be gained with a Shorai. I ought to know because that is what is in there right now.....along with a lot of foam shims.

Sorry if this a bit off topic, but why on the S2R-1000s did fitting the DP ECU cure the surging, but it doesn't on the new EVO's ?

Hoping an expert can answer your question. All I know is that the DP ECU did not cure the surging on my 2012 1100 Evo. I do have a friend with a 2013 and the DP ECU smoothed his out, but it still is not as smooth as mine with DP ECU and PCV and AutoTune.

There are enough variables so that one tune will not provide exactly the same performance on all bikes.

the siemens ecu in the m696/796/1100 bikes is closed loop in both oem and dp mapping.  as is the Mitsubishi ecu in the mts1200, diavel and panigale.

the marelli ecu 5am ecu is closed loop in most oem applications 2006 onwards, but open loop in dp, except for some of the 848 I believe.

the closed loop operation is what makes them surge.  why it makes them surge is clearly something the manufacturers and ecu suppliers can't work out.  they've been trying for a long time without real success.

....why it makes them surge is clearly something the manufacturers and ecu suppliers can't work out.  they've been trying for a long time without real success.

I'm guessing its that they're struggling to comply with ever more stringent emissions standards... and in their quest to comply... fueling suffers to the point of unpleasantness.

I believe you are correct. More downside for Ducati to run afoul of emissions standards than to have disappointed customers. But, on a somewhat upside, those standards have created a growth industry ala PowerCommander and Bazzaz. 

[Uncle Mofo]

I think I want to add a Bazzaz ZFI to Termi ECU on my S4RS anyone with FHE?

I disagree.  closed loop is closed loop.  it's a controlled feedback system with the same sensor now for years.  the main change with the euro stds is that they increase the scope of the closed loop operation.  well, the emissions targets require an increased range of closed loop operation.  meaning instead of up to 100km/h for euro 3 it became up to 130 for euro 4 or some thing like that.

it's not a choice manufacturers make whether to comply or not.  not complying simply means the bikes cannot be sold.  the only way to meet the targets is closed loop and cats.  that's it

True closed loop is closed loop.

But more closed loop is more closed loop.... and increasing the scope in order to meet emissions targets exacerbates the fueling unpleasantness.

So yes - as you rightly say - they MUST comply and in doing so the resulting nasty fueling (due to extended closed loop) is the result, no?

Agreed. That is what I was attempting to say, with tongue in cheek. Guess I failed.
