Graves R6 Garage

Got a tech question on your R6? We'll do our best to help out.
Get technical info from the Graves Motorsports Staff and Race team. Occasionally one our own Race Team mechanics will step in and take on tech questions that can only be answered by the pros.

Lets keep this thread strictly R6 tech and we will get some questions answered. I will also be adding some standard technical advice that is relative to Graves products and/or just plain fun to talk about.

Thanks, Taige

Hi,

I have a 08 R6 and in the process of installing the Graves Full System (lovely bit of kit!!), and I was looking to install the mapping you have on your site. However it states that the mapping is with the O2 Disconnected.

My Power Commander is on the way, but I thought the installation instructions of the PC are to also connect it to the O2 Sensor. If I disconnect the O2 it will give an error code on the dash. I have heard of O2 eliminators but have not found one yet.

What’s the best way to get rid of the O2 sensor and have the PC3 installed with the Graves Map.

Thanks
Michael

Hey Michael,
On the 08 R6 removing the 02 sensor will NOT throw a code. There are bikes out there (GSXR) that will throw a code when removing the O2 but not the R6. You do not want the 02 installed with the PC111. It kind of negates the action of the PC. The Power commander is delivering a linear fuel map to the injectors to offer the most power and if the map is correct then that is the right way (for now). If you leave the O2 hook up then it will want to "fix" what the power commander is already doing so well. If the bike makes power running lean at 12,000 then the PC111 map will do that(if mapped correctly), but if you have the 02 hooked up then the ecu will not want you to run lean and will "correct" that, inturn removing the beautiful horsepower your tuner just put in it. Remove the O2, install the PC111 (mapped), and have fun.

Hey guys, i have a 07 R6, and have your Full Ti system, but my muffler fits really really loose on the system even with the springs attached and clamp mounts it will move, and leaks around the pipe. any suggestions.

on another note, a friend of mine who knows one of your mechanics told me to leave the O2 sensor plugged in. should i remove it or leave it in, im running the PC3

You want the slip joint a little loose however it sounds like your exhaust is excessive. Email me over here at Graves so we can work out some details and get everything perfecto.

If you are running a PC111 I always suggest not running the 02 sensor. The reason to install a PC111 is to overide the stock ECU fuel map and put a custom fuel map for more power (if you have the right tuner). If you run the O2, I feel that the bike could have issues going back and forth between what the ECU map and the PC111 map. Either way if you have a quality tune on the bike there is no reason to run the O2. If you want to step up on Aif Fuel managment the better direction to go is to eventually invest in the NEW PCV and Auto Tune. This creates a closed loop system that can adjust the fuel delivery for different scenarios. Plus it has an option for 2 maps (performance and econo etc). Thanks Taige

Hi everyone,
I have a question concerning my 07 r6. I have a Graves full titanium, PC3usb and a GYTR filter. I had a dyno run that only produced 103hp max and A/F was fairly level at about 13.5 to 14. (Guessing from the previous post that the o2 sensor is negating my PC?) I was going to add Graves block offs and have it mapped.(currently have the graves 06 map) My question is will removing the o2 sensor before the mapping cause it to shoot a code on the dash and if so how do I cure it and what is available to block off the hole where the o2 sensor was on the Graves system? Thnx

Removing the 02 will not throw a code. However running it along with the PC is definitely not optimum. You are going in the right direction. Put the smog block offs, remove the 02 and unplug it from the harness. Get it tuned with good map by a QUALITY tuner. Our maps are fine and in some instances are excellent but it really depends on elevation, humidity, the modifications, etc.
A custom tune is always recommended. I used one of our maps on my R6 and it worked great however when I got a chance to have one of the guys build a custom map for the PC and it really made a difference. Gained a little horsepower and actually got a little better fuel mileage.
The exhaust comes with an aluminum plug for the O2 collar however if you do not have that then they are available on the website. Thanks, Taige

Hello, I was on the Graves site and saw you have the Power Commander V for the 08 R6. I heard you also provide a map if purchased from you...Do you only have a map for the Graves full? I ask as I have an Akro Full system. Also about what gains have you seen running the new PCV and no 02 compared to no PCV and with the 02.

Thanks

We do have the PCV and Auto Tunes in stock. We do have the full system maps but you are correct.....they are for GMS full systems.

As it goes for the differences on the PCV ...we do not run them with the stock O2 sensor installed at all. We either run a PCV with the O2 collar plugged or we
run the PCV with the new Auto Tune. The Auto Tune make it a closed loop fuel management system.

1. You say you either run a PCV with the 02 plugged (did you mean unplugged) or a PCV with the auto tune.
2. So you do use the PCV with the 08?
3. Is there a place you can download maps like the PC3. I went to your site, but I have have another link that you have to signup with Graves and the price is better.
4. Is that price not valid?

5. Basically I am trying to figure out the advantage of the Power commander. In the past I have always used Kawasaki Race Kit ECUs (with Kawasakis of course), but with Graves and Yamaha only taking orders a few times a year and the price it makes it difficult. The 08 R6 has so many sensors and the 02 you would think at 1st glance that it has some great technology. So seems if I go with the PCV you would really need the autotune.
6. Would you run it during the races and practices...as temps are always changing.

1. You say you either run a PCV with the 02 plugged (did you mean unplugged) or a PCV with the auto tune.

PLUGGED (no O2 sensor). The exhaust comes with a plug blocking off the
O2 sensor collar. Leave it like that and do not run the O2 sensor.

2. So you do use the PCV with the 08?

You can use either the PC111 or PCV. I stock both but at this point I would recommend the PCV. Its got a lot of NEW features. I personally run the PC111 with ignition mod which is excellent but soon enough I will end up replacing them with the PCV.

3. Is there a place you can download maps like the PC3. I went to your site, but I have have another link that you have to signup with Graves and the price is better.

I have to download the maps into the PCV's when they leave the facility. I am not aware of any place you can down load our maps from currently.
I am sure dynojet will soon have some up.

4. Is that price not valid?
If you are refering to the "Works" website, then yes the price is valid however you must be a licensed racer and have the profile completed in full.

It is not a absolute necessity however it is a really good upgrade and the technology works. It has all of the user friendly features of a PC but in a closed loop design so everything can be tune in very detailed and basically on the fly. You can run the base map which 99% of the time is great but the Auto Tune can adjust that +/- 20% to really bring the air/fuel in perfect.If you like that map you can save that map as the base map and go from there.

6. Would you run it during the races and practices...as temps are always changing.

I am still learning about this NEW PCV and Auto Tune but from the things that I know and from the riders and racers I have talked with...I would say Yes....run it during both practices and races. You can put it on a switch so if you find a map that is a guarantee to work and the Auto tuning is just not giving you the power right at that second you can switch to the base map and go. Its just another feature that this fuel management gives. Thanks, Taige

No.......single but its good size

Thanks for your comments

What do you guys run on your race bikes, PCV or YEC?
Have you guys used any Bazzaz Fi equipment on your race bikes?

Hi,

I have been running a full graves system with PC3 and your map for most of the year and all going good. However I am looking to purchase the YEC Loom and ECU for my race bike. I understand that the ECU comes with default Stock and SuperSports options. My engine on the bike is currently standard, so works fine with the PC3. Not sure which way to go here. Keep the PC3 with the graves map and hook that into the Race ECU and Loom? Or am I looking to getting rid of the PC3 and having to get the Race ECU tuned for the Race Filter and Graves Race System. Any help would be appreciated.

Thanks
Michael

I have the older Ti Full Graves exhaust with a newer carbon fiber can on it. I noticed you guys now have the blak end cap on the carbon fiber can (mines not). Can the aluminum looking cap be replaced with the black one? Further, do you have a map for this exhaust configuration, it probably doesn't matter much, if I go with a PCV? Thanks

You should email me at Graves so I can go more in detail on this however, just a quick note on this.

I would suggest retaining the PC along with the ECU. It is easier to do a quick tune and mapping to and you get really get details on the fuel curve.
Also if for some reason need to change the mapping for another track or something like that, you will often run into someone who has no clue how to tune a Kit ECU and you will be stuck with what ya brung. If you have the PC delivering the fuel map then you will always have the ability to get it tuned.

There are definitely benefits to running both. Email me direct and I will be able to give you some additional info. Thanks, Taige

I cannot really comment on the details of the race program however I always suggest running the PC along with the YEC. There is another post in this thread that explains why.
As it goes for the Bazzaz product. They build a quality product, the main reason I push Dynojet over them is simply because tnot only are they built with quality and durability but they are currently the industry standard.
It might sound like a weak reason for my choice however..... I know and talk to a lot of people in the motorcycle industry and I would estimate that if you asked every tuner/mechanic "can you tune my bike with a PC installed", 99% of them would say "no problem, Ive been doing it for 5+ years, bring it in". Unfortunately
if you ask the same question but switch Bazzaz instead of Dynojet you will
get a lot of people that say "I can probably do that for you" "or I have not worked with one yet but Im willing to give it a shot" .... most of the responses will probably be along these line.
Now this does not at all describe the quality or features of the Bazzaz unit. Like I said, my opinion is, it is a well designed product with really great features and could one day be the indutry standard but that is just not the case right now. Thanks, taige

You probably have a titanium entrance and exit tips unless you purchased our Show Stopper series which has polished stainless caps. The carbon tips are not available as of right now. We did a run of them but they are made in very small runs and as of now not cost effective to offer. You can have a black coating put on them that I have seen and it looks great. Email me for more info if you are interested. Thanks, Taige

Taige,

I tried emailing you but it came back as an invalid address. I have a question well 2 actually. The map you sent me was that for a full exhaust or slip on? I have a slip on right now currently saving for the full system. Second I installed my block off plates and the map you sent. My exhaust now has a strong fuel smell. Could this be due to the block off plates or the map?

Thanks in advance.

hey guys how are you hope all is well .... last week i got lucky and bought Michaels Becks 08 Yamaha Graves R6 for great price and im going to race it WERA or WSMC this year before i start racing i am looking for a graves mechanic to take a look at the bike for any problems im sure he brought the bike to you guys and im sure name Toki sounds familiar to you right LOL ... is there a mechanic that you can reefer me to or i need to bring it to your shop i dont live to far away from you guys so it wont be issue to me to drive by and talk to you guys ...

thanks for any info you can relay to me

Is there anywhere I can go for instructions on how to repack GRAVES muffler and do you have any replacement materials for them? Thank you, mark

I'm having a problem with my 04 R6. It has 9K miles and only a Devil high mount pipe. I took the bike out for a ride and when I was at a light about to pull away I stalled(I just didn't give it enough gas). I started the bike back up and immediately noticed the change in the exhaust note, very deep, almost sounds like a Ducati. The bike also has no power and barely any throttle response. I started to visually inspect for anything obvious but couldn't find anything so I started taking off some stuff. I just got done installing your block off plates, new plugs and I also put in new fuel, then disconnected the battery. I figured I'd change the plugs while I had them out but I wasn't really expecting it to fix it and it didn't hah. The bike still runs awful and has no power.

Any thoughts?

You can check to see if you installed the smog plates so that they seal the block correctly. They just remove the emissions setup for racing though and wouldn't change anything else.

Re-check the plugs since you recently changed them. From there un-hook the power commander if you have one just to check. At the point your engine would need to be looked at... GOOD LUCK.

I meant update my post. I had a bad ignition coil which was causing a constant misfire.
