    Bajadave - Sorry to be so inactive, been busy. I have the 450 six days version. My wiring diagram show that there should be a gear position sensor on pin 18 (Brown/Green wire) I see the wire coming from the left side of the bike by the shifter but the run up under the tank and do not have time right now to trace them down. I did get my ECU remapped with the EURO map. Only have ridden on the street. Feels a little bit crisper and the idle does not wander anymore. Hope to get to the dirt this weekend.

    One other discovery. There is a smog component located behind the motor that recirculates fuel/vapors from the charcoal canister. When we originally desmogged the bike you had to leave that on and plugged in our the engine light would come on. Now that the EURO map is installed I unplugged that and the light stays off. I could not locate this circuit in the manual. Now that I have had time to look at is closer it looks like this goes to pin 8 on the ECU. Not found in the manual but the wire color (Black/Orange) matches on the ECU and the sensor.

    I have ordered a map switch and the plan is to try to install it per the manual wiring diagram. Does anyone know if the standard map is the "mellow" mode or the "aggressive" mode? Traction control is self explanatory, either on or off.

    Yeah, they do all have the gear position sensor.

    The bike runs fantastic even with the emissions crap, but now that I've got the Euro map installed I'll probably yard it all off to declutter the engine and lose a few ounces.

    If you haven't purchased an aftermarket pipe, you can remove the screens at the very tip of the muffler and pick up a very noticeable boost in performance as well.

    I'm going to do the same with the TC/Map switch... just wire it in to the existing harness using wiring diagram. Map 1 is the standard map, Map 2 is the aggressive map.

    I spent the night creating a spread sheet to show the differences in all of the schematics regarding the ECU connections. You can determine the necessary changes from each schematic without flipping pages.

    I did receive the new exhaust pipe and Lambda, but it did not get rid of the flashing code 53. I will need to take the bike to the local shop and have the EU map installed.

    FYI, the Six Days US schematic is not correct. My 450 Six Days US was wired like the EXC-F US schematic until I changed out the main wiring harness to the EU model. The main difference is the US model has the M20 Evaporate Valve and does not have the Lambda or Map / TC.

    Im confused. It specifically said in the advertisement that the bike has a map switch.

    Only certain countries?? if so, which countries?

    The US bikes do not thave the Map Switch wiring in the main harness. You will need to either modify the harness or purchase an EU harness to add a Map Switch. Read my earlier post on page 7 regarding part numbers and links.

    If you are going to try and add a Map Switch to a US harness, you will need to add pin connections to the main ECU plug. I could not figure out how to do that so I bought an EU harness that already has the Map Switch wiring.

    ruddle I believe that we have the correct location on the ecu plug for the map/tc switch. they are empty on the US wiring harness. Just need to get the correct pins for the plug. I received the map/tc switch yesterday and the wire colors look to match the wiring diagram description so we know where they need to go. It will be awhile before I get around to this. Have a 3 day ride I am going on so no messing around with the bike before that. Will try to keep this site updated with our progress. Thanks for posting the spreadsheet with the pinout for the ECU. I had made a similar one for just my bike and it seems to jive with yours. I am thinking that we only need to add pins 28 and 32 for the map/tc switch and then pickup power and ground. Power for the ECU looks to come from Fuse 1 so tapping into the orange wire. I don't see why we can't run the ground wire to a ground on the bike. Any thoughts here?



    Thanks for the response Dave. I posted some additional thoughts below.

    When you removed the screens from the exhaust did that change the sound level? How about a spark arrestor?

    I left the spark arrestor in place. It has a very large surface area and should not be much of a restriction at all in terms of flow. In fact, when I took off the cap, I gave a couple of good hard blows in through the back, through the screens before removing them to get a feel for how restrictive they were. Once removed, I did the same and it was night and day difference.

    The sound level went up, but not very much. I would still not consider the exhaust loud at all. Of course the stock sound with the screens intact (and the reed valve in the intake) is super quiet, quietest of any bike I've owned. Pulling the screens made it about as loud as my 2009 690 was when it was new with stock exhaust. Not bad at all. It sounds more like a motorcycle now, less like a scooter.

    D you please tell us about how much $$ for the EU harness, map + TC switch, plus EU exhaust & O2 sensor

    Bitingdog, you don't need the exhaust and O2 sensor if you are going to load the EU closed course map, as it disables the O2 sensor (and emissions breather valve warning light, I'm told). If you want to run the EU street legal map, then you would get a flashing FI light if you don't have the O2 sensor, but why would you want that map?

    I want the good mapping and TC. Now that you've proven it's remappable, I feel safe buying one :)

    With the crank position sensor going to the ecu is it possible to piggyback off that output to a tach somehow?

    Where does the 690 get its signal for the oem tach?

    Good luck getting your bike mapped in CA, Ive found no dealer that can or will do it.......

    Just want to reiterate this for clarity: If you are wanting the TC/Map switch and to run closed-course EU map, then you do not need to add the European exhaust header or the Lambda sensor to your bike. That is $550 worth of parts that will do nothing for you if you are going to run the EU closed course map we've been discussing. The O2 sensor is disabled with this map. You only need the switch and harness (or to modify your existing US harness if you are comfortable with that sort of thing).

    I just got back from the bike shop. They installed the 450 Six Days EU map and all is good. No flashing engine light and the bike runs great. The service manager told me that they only offer two map options for my bike. I had a choice of the Six Days US or EU map. They cannot load the Off Road version for some reason. I'm glad I purchased the Lambda switch.

    If you are planning on adding a Map switch, I recommend adding the pins to your existing US wiring harness. You will not need to change any mapping. The Map Switch will work simply by plugging it in.

    If you choose to install the EU wiring harness and EU Map as I did, you will need to add the Lambda to prevent the engine code or add a Lambda bypass plug. This information is directly from my local dealer. You will also need to extend the Kick Stand switch wires to the ignition key switch. The smog vacuum is eliminated with the EU harness and Map.

    I also removed the tip of my muffler and eliminated the cone / screen obstruction. The spark arrester is installed in the middle of the muffler so I am still legal. The bike is not louder but runs much better.

    Cool thread!

    Hey anyone know what will be the best map for lower octane fuel?
