919 Danmoto PC3 map

Just put my PC3 USB in last night, currently running the Moriwaki map. My mods are Danmoto GP slip ons and a bikemaster filter (please don't crucify me, I like reusable filters). Any different suggestions on what map to try next? I will be trying the Moriwaki for a few days first.

I also have the Danmoto GPs on with a newly installed PC3, though i've just left it with the stock map.

To clarify, the Moriwaki map corresponds to the mw919mori4.djm file ? I'm guessing that's the one since there's a mori in the name :P

Also are you using the latest dynojet software or the older gen ones?

I'm a super noob when it comes to this, so any additional info that I can get on how to update the maps properly without breaking the bike is very very welcome

Yes that's the Moriwaki map, and I have the PC3 USB and am using the maps that have been converted. Loading maps is easy, all you do is plug the USB into the PC and the laptop and select a map to send to the PC. I switched to the Sandy map for the Yoshimura slipons with a BMC filter and that seems to be a bit better. That map was also done at altitude so it might work better for me being that I'm at about 2,500 ft.

Make sure you calibrate your throttle as well using the laptop.

Or, slightly rephrased, be sure the synchronize the PC3usb to the Throttle Positioner.

I'll also add a bit more for the benefit of all:

If the PC3usb is not synched to the T'P, then the PC3usb's correction map will be out of synch with the ECU's baseline map.
Imagine a two identical grids, one being the ECU's baseline map, the other being the PC3usb's correction map, and wanting the correction grid to lay perfectly over the baseline grid.
Keep in mind that that PC3usb holds a "map correction" and not a "corrected map", the PC3usb being a "piggyback device".
The PC3usb instructs the ECU to correct its baseline map continuously in real time by altering the pulse width signal to the fuel injectors.

Synch at the Closed and the Open positions, the Closed position being far more critical in terms of rideability effect.
Don't just do it at the Closed position, unless the check shows the Open position already displaying 100%.
I've seen Closed position errors ranging from 2 % to 5 %, 5 being a huge error if one is riding in slow traffic with weeny throttle openings at low revs.

The so called Moriwaki map is from LDH's 2002 era dyno work.
The present day file named mw919mori4.djm is my djm conversion of the original .map version as I found on 919.org
That particular map is the 4th and final iteration (Sept 15, 2002)of LDH's dyno work with the Moriwaki cans he had on his bike at that time.
It's an excellent map.
It's not a track use oriented max power map like some others are, such as the Dan Kyle Large Bore Satos map.
What it is, is a really good "rideability" map with smoothed out torque curve all the way across and some power gain.
It's excellent mapping for the typical real world broad spectrum use of the 919, as in street/touring through to track days.

Cool thanks for the detailed information !

I'll do a bit more reading from the dropbox, I saw there were how tos in there on how to do the throttle sync (though they did use an older software) but hopefully I can figure it out.

It's pretty easy, I'm not sure what it said for yours but I used the 9 volt battery to trick it into thinking my bike was running. It won't recognize your throttle position on the laptop unless it's "running" so the 9 volt tricks it. Unless of course you own a dyno or don't mind pinning your throttle for a few seconds lol.

The 919 can be done without the use of the external 9v battery.
Simply have the key in and turned to the run position with the engine not running.

^What he said... I thought all bikes/power commander set ups were like this... It took me forever to figure out why it wasn't working on my GSXR track bike...

I found out about the 919 just trying it.
Then I found out about the GSXR by tearing my hair out just like you too went through !

turns out i only had 1% of throttle position difference thing... corrected that then sent the moriwaki map :P Thankfully I'm also very close to sea level 130ft so it should work nicely.
