Yosh Pipes and PCIII

Just bought a 2007 919 and it came with Yoshimira Carbon pipes and a PCIII installed. I haven't been able to find a map for these pipes, and the PO said he talked to the guy who runs 919.org and he suggested running the map on thier site created for Sato exhausts. The bike seems to run decently, although the low end feels a bit chuggy. I know this is a problem with these bikes but everyone seems to say it goes away with the power commander. Does anyone know of a map specifically for these pipes, or have any suggestions on where to start changing it up?

All the maps we have are here:

https://www.dropbox.com/sh/ra9j3gn4czozojw/RW_e95OpKJ

Look in the 919 folder, then Power Commander maps. There is a .zip file you can download.

The software as well as user manual are in there as well.

Don't forget to synch the PC3 to the bikes T'P' and all such info is in the drop box.
Find the V4 Moriwaki based map, use that as your starting point.
The original Dan Kyle Satos map is rich for street use.
My custom map is on the mix as well (TRSs on a 05)
You have an 07, I believe they all have a cat convert element in the exhaust, so my sense is that it shouldn't breathe as well, although I've never heard of nor seen any dyno results supporting that comment.

Good call on synching to the throttle position... The way PO had it set up it was at 5% with the throttle closed and only 92 with it wide open, and with a more correct map! Wow what a difference! It even got rid of some buzziness I was dealing with

I've also heard something about the the Pair Valves causing issues when you get your ride dynoed running a PCIII. If you're 9er still has the pair valves, you may want to look into getting some block off plates. Lots of ppl have bought them here.

The PAIR system adds extra air to the exhaust stream after it exits the combustion chamber. This promotes after firing in the exhaust burning up any excess unburnt fuel.

A proper dyno tune will use a wide band 02 sensor installed into the exhaust stream to detect the air-fuel ratio.

By adding extra air the PAIR system leads to a false air-fuel ratio reading, making the bike difficult/impossible to tune using a wide band.

Blocking off and deleting the PAIR system will fix this issue and allow you to properly tune the bike, with no negative side affects to the bikes performance or reliability.

Is that on all bikes or only CA models?

I'm using the map for the Erion slip ons right now, as the mori map is a .map file and isn't recognized by the program... any ideas how to turn it into a .djm file or make the power commander program open it?

You have to do a "File"/"Open map", but then drop down the "File type" box to include all file types I believe.

There is an option somewhere in the software to open older map types and convert them to the new format.

right now the only file type available in the drop down menu is the .djm.... I'll look into it and see if I can find anything else

Look in the mcromo compilation subfolder of the dropbox
All that you seek is there.
And then some.

I found the Erion map to be rather poor on my bike with the TRSs on.

The Erion map was way better than the sato one, and now I'm running the two bros one just for a ride around the block and its even better... I'll see if I can get the mori map to work and see what happens

FWIW, a quick run around the block is not enough to truly test a map. The first map you tried with a cold engine, then loaded a new map on an already warmed up engine. Not exactly quality test standards.

Run a map for a week. That way when you compare two maps, you'll remember the same circumstances under each map (cold engine, cold engine start, hot engine, midrange pull, top end, fuel economy, etc.).

Or even just one run map for an entire tank of gas. Should get you a good feel for what each map has to offer. Also gets you out riding more, as there are TONS of maps, .

This is extremely sound advice as variations in engine temp and other factors for that matter drastically affect the drivability of the bike. The 3D mappings of the ECU are very complex and without a lot of rhyme or reason for the most part. Keeping the bike at normal operating temperature is a must when evaluating any type of performance enhancement.

The djm format mori based v4 map is there.

Have you synch'd ?
You are wasting time by getting misleading results if you have not synch'd or confirmed that the PC3USB is in fact synch'd to the bike's TP.

The others have already commented on the need of a decent trial ride on a fully warmed up normalized coolant temp engine.
To that I'll add, on a bike with a properly adjusted throttle cable, every factor door 919 I've come across or heard of, being way too loose.

Not that I can recall off the top of my head. Pretty much everything on this site has been around for years and just gets regurgitated every so often...

The throttle cable was super loose when I got the bike, and I have synced it. I had the Erion map on for a couple days, and now I'm running the two bros map... I ran around the block to check it out, and I'm going to keep it on for a couple days as well. (A couple days is multiple tanks of gas for me) thanks for all the advice, especially checking the throttle position... I never would have caught that one...

This site (& your original site) is a tremendous wealth of 919 info. I'll continue to use the search function to dig it up. I hate being the one asking the same questions everyone has long since tired of answering.

Resurrected sounds much more positive.
Not only that, when stuff is regurgitated it has been acidified to some extent, so is really rough on the taste buds.

Seeing some of this stuff brought up again and again does tend to leave a pretty bad taste in my mouth...

Didn't mean to inconvenience anyone by making them regurgitate old information... :P I hadn't found the search function before now so I'll make sure I start looking for old threads before I start new ones in the future. Thanks again for all the help though.
