This tech tip is meant to help give you an idea what may need to be done and is for entertainment purposes only. Read the entire post to have a good idea of whats to come. Some of the steps will be generic and not described in detail (ie removing tail section plastics) this post focuses more on the actual ECU details. Step 1 Goal: Remove tail section plastic to uncover ECU that is located in the tail, left hand side (clutch lever side) of bike. Remove both seats Remove tail plastic (there are 3 sections of plastic fairing that need to come off) The ECU is on the left side, and has a cable bundle going to it Step 2 Goal: Render bike electrically safe, prevent damage to ecu and other electrical components. Make sure ignition key is off & out, Remove negative terminal cable from battery Secure cable away from the battery Step 3 Goal: Remove ECU from the bike, taking care not to damage ecu or its connector The ECU is secured in place with a rubber boot (that attaches to the rear sub-frame via two tabs) The ECU is also connected to the wiring harness cable bundle via a plastic connector The connector has a rocker arm latching mechanism as seen in this photo: This rocker arm needs to be gently rotated away from the ECU body (to the left in this photo) Here is the Rocker-Arm rotated away, which disconnects the ECU from the cable bundle: You can now remove the ECU from the bike, and you can remove the rubber boot from the ECU itself. Here is the tail section with the ECU removed and rubber boot back on: Do not touch the metal pins on the ECU itself, this is the main computer/brain of your bike and is an electronic and sensitive device (not to mention expensive to replace) Step 4 Goal: Ship ECU to your flash tuner of choice Package up the ECU, preferrably using a static shielded bag (like the type used for sensitive electronic computer components) and appropriate packaging, and ship to your tuner. Follow the tuners advice for shipping and labelling. Step 5 Goal: Install ECU back into bike You just got your ECU back in the mail! Follow the above steps 1,2,3 in reverse order to install ECU back into your bike Step 6 Goal: Check to see if the bike is running ok, and if there are any check-engine faults stored in ECU Once the ECU is safely back in the bike, start the engine and look at the dash If you have any faults in the ECU the check-engine light (yellow light directly below ABS light) will be illuminated like in this photo: If you do have a check engine light on, you can: Ignore it (not recommended) Take the bike to your dealer to have the trouble codes cleared (nah!) Or go to the next step, and take care of it yourself! If there are no check engine lights on, you are done! Go for a ride and enjoy your ride! Step 7 Goal: Check, Clear, Verify trouble codes stored in bike You will need a Yamaha-to-OBD-2 adapter cable like this one: (you can get yours on Amazon, they're cheap or borrow one from someone?) You will also need an OBD2 code reader, any generic OBD2 code reader that you or your friends have will do the job. The T7 has its Yamaha OBD2 plug located under the rider seat, close to the battery. (yellow arrow points to plug) Remove plug (its held onto the bike tail section via rubber boot) and plug in the Yamaha-to-OBD2 adapter cable Plug in your OBD2 code reader to the yamaha obd2 adapter The code reader will power on as soon as its plugged in Turn on your ignition key to the ON position, but DO NOT START the ENGINE Engine MUST REMAIN OFF for entire code reading/clearing/verifying procedure Follow your OBD2 code reader prompts and "read the codes" In this example we can see that the status shows: MIL status ON (meaning, check engine light is illuminated on dash) Codes found: 6 (meaning, code reader found 6 fault codes) The rest of the monitor status is not important. The codes present after the ecu flash, are incidental codes, they are not actual codes indicating an engine or ecu fault and should now just be cleared. Clear the codes using the OBD2 code reader (this is a normal function of any OBD2 code reader) Steps to do this will be dependent on the code reader you are using, but generally after you "read the codes" you will then have the option to "clear the codes" follow your obd2 code readers manual (if needed) to clear the T7 ecu stored codes. The procedure is the same as if it were performed on a car. Once the codes have been "cleared" Again "read the codes" using your obd2 code reader to see if there are any stored codes, (this is just to verify cleared status) Here you can see that the status reports: MIL status OFF (meaning, check engine light on dash is off) Codes Found 0 (no stored trouble codes) Disconnect the OBD2 Code Reader, and the Yamaha-to-OBD2 adapter cable, place T7 obd2 plug back in its rubber boot and make sure its secured to the bike. Turn off your ignition, wait a few seconds, turn ignition back on, and start your engine Check your dash Yay! check engine light is OFF Install your seat Step 8 Goal: Enjoyment Go for a ride and enjoy your bike!
