Cockpit LCD computer for PCIII

bitingmosaurus · 03-27-2007, 09:22 AM

Anybody have one of these yet?

Here are the specs / features:

Expand Power Commander Usability
The LCD Display connects to any Power Commander USB via a "quick disconnect" cable. The weatherproof design allows for the display to remain installed on the motorcycle. While connected, the unit will display all the available data from the Power Commander. When the optional Multi-Function hub is also installed data from the devices connected to it become available for viewing as well.

The onboard memory allows for the storage of multiple maps. Once stored, these maps can be sent to the Power Commander "on the fly". Additionally, maps can be custom adjusted using the controls on the display. The LCD Display has the ability to log the data being displayed for later analysis.

The LCD unit has an SD Memory card slot (memory sold separately) so that the amount of data storage for maps and logging can be increased at any time.

Looks pretty sweet. The ability to switch from a cruising "fuel conserving map" to a high performance map on the fly would be very nice.

Not to mention the cool factor of a cockpit mounted high tech gizmo like this.

I've seen it.
looks nice, but for our scoots it's rendundant.
OUR powercommander (for the R1100S) uses an 02 sensor in 'closed loop' feedback mode, due to the constraints of interfacing an 'intercept box' with the motronic CPU.
the PCIII does NOT use the base map for the closed-loop part of the system (0-80% throttle, 0-7K RPM, going on memory) for more than a few milliseconds, the time it takes for the 02 sensor to provide feedback ( I quizzed dusty schaller at DJ on the response time and he assured me it's in the millisecond range)
so 'switching maps' isn't in the cards for us, at least as I understand it.
I was excited as I need a top-end fuel-enrichment schema to use a dry nitrous system.
yet another benefit of owning something NOT in the mainstream...

Thanks for the imput Jony,

I still think it would be nice to have for the data logging aspect. You could download your data with the device and then use it to optimize your map, when adding performance components.

And a flashy LCD display with engine / fuel curve data would just be nifty....................

you really don't need a hardpoint data logger.
I have the optional DJ air/fuel meter. I note when and where the meter 'sees' rich or lean and then adjust accordingly by-the-roadside with a win-doze laptop.
as I said, there's precious little 'adjustment' here, almost exclusively in the upper RPM and throttle position ranges, since the 02 sensor gives 'closed loop' feedback throughout the vast range of throttle positions and engine rpms where most realworld riding occurs.
Now, the REAL way to do all this schisa would be a complete aftermarket CPU with timing adjustment.
Motec makes one; it's $4K USD, but that's what it takes to play with the big boys.
autosquirt makes soemthing similar.
I have something similar in my boat, a holley commander 950. that CPU was only 1700.00.
Dynojet (Dusty Schaller) said the bosch motronic 2.4 was the biggest bitzh to piggyback a box on they had ever seen. He said if they had to do it over they wouldn't.
this is NOT rocket science.
with a known-quantity input (IE, map, tps, ignition timing/advance, injector duty cycle, etc) it's 'simple' to program a CPU for the results you want and even better if it has 'feedback', read 02 sensor for 'closed loop' (and 'simple' is subjective; nuclear fusion is 'simple' to a physicist).

Check,

Thanks Jony.

Ya, nuclear fusion is very simple in theory. Sustaining the chain reaction in a controlled environment is the problem................

:P

Not necessarily true. Stars are just dumb balls of gas and they do nuclear fusion just fine.

More to the point I would be interested in a programmable LDC interface that I could set up to show me TRUE speed (not BMW's inaccurate and goofy values) based on an accurate wheel diameter measurement, AND that I could program the torque curve into the video output so I could see right where my RPM was on the torque curve.

Really, with all the flat screen technology available there is NO reason to have meters with moving parts. If you have to have meters, then they should be completely mechanical from the engine or wheel to the dial so that they could survive an EMP. Otherwise, what's the point of a hybrid system? (I know, it's cheaper... but is it really cheaper? This stuff costs nothing these days.)

Moybin,

You missed the "controlled environment" portion of the quote.
Stars are in fact big balls of gas............The immense gravitational forces within the big (ginormous) balls of gas allow the sustained fusion of hydrogen ions..............A rediculously simple process considering the rest of nature.

Unless there is a control room in there somewhere..............

Anyway back to the point, I agree on the LCD interface, the combined RPM / torque curve thing would be neat. This is why I usually rely on the "LCD" data screen of my GPS for accurate speed....
