ZARD owners

[hillbillypolack]

A very reputable local dealer advised pretty much against the Zards.  I know they look awesome, but the popping and "post-install" tuning were not easy, or cheap.

The way I understand it is that the standard ECU is and always will remain a closed loop.  Meaning you can't trim any parameters on it.  You can add a PCIII, but it seems people who have done the exhaust mod wind up buying the Ducati Performance ECU.

What that allows (again, this is my understanding of it) is an open loop system.  Now, it's possible to trim the CO (with the DP ECU).  If more mapping is needed, the system will be more responsive to it.

+1 Thats a good point if you have a S2R1000.  I have an S2R8, with no O2 sensor but if I had a 1000 I would probably go with the Termis or just leave it stock or else there is going to be too much B/S to deal with.  But I don't think its just with the Zards I think his advice is for any after market system excluding Termis.0

Thanks Ivan & GusDuc - this thread has been extremely useful because you've both taken the time to lay out important diagnostics, upgrade details and test results.

Ivan, if possible I'd still be very interested in the DP P/N you ordered, in part because to facilitate my shopping I want to confirm whether Ducati uses a different P/N for the same ECU depending upon whether it's in the Termi kit.

GusDuc, I've read yours and others posts on TOB plus this one on the HM ECU, and remain a little confused as to whether this is an equally good option to the S2R1K DP ECU (or if it's equal technically but cheaper, in which case perhaps it's a better option).  Can you elaborate on that once again?  If you consider it a recommended option, and you bought the HM ECU standalone, can you provide the source and P/N?

Ivan & Gusduc - Did either of you do any back-to-back tests with and without the open airbox?  Based on your experiences, do you consider that to be an obvious complementary mod with the full exhaust/DP ECU/PCIII/dyno tune upgrade process, or are there still good reasons to leave the airbox alone with this config?

Thanks again guys.

Glad I could help Dave

As Ivan mentioned I'm into my set-up for less than $400 including the dyno pulls...... the open lid does make quite a differnce IF, & only IF you have an ECU that will keep the A/F between 12.5/1 & 13.5/1...... if not, you'll be too lean & lose some power.   It's not too much louder ith the open lid but much deper & smoother sounding although you do get more intake noise.... I can't seem to hear it over the Arrows though

The only problem I've had with the HM ECU is that eery once in a while, when I start the bike, the tach freaks out & the dash stays lit.  If I notice it right away & shut it off, the dash goes off & i can restart it & everything is fine.  If I don't catch it & leave it running, I have to unhook the battery to turn it off. I think the HM's have a sensor that my S2R1K doesn't have & occasionaly this causes an issue.  To me it's a small price to pay for the much better power & A/F not to mention how much better it feels   I'm running the DP HM ECU designed for the 2 into 1 system & not the cam ECU...... the tech @ Spectrum said that the HM ECU dumps plenty of fuel in down low & could make a little more power with a PCIII & a remap.  I chose to leave it alone as it's not worth another $400 or so for 1 or 2 HP & I like less things plugged in

p.s.  Thanks for posting the dynos Ivan
