This is my Arduino controlled exup eliminator that will fool the Yamaha R1 ECU into thinking the exup valve is still connected thus preventing error code 17 on appearing on the gauge.
It has been a lot of work getting to this point. Lots of wires have been stripped out of the loom and modifications made so it can be run in the mini.
The video says it all. It lives!!!!
The fault codes are expected. I don't have an exup, air or water temp sensor connected to the loom.
With the wiring loom modifications mostly complete it was time to offer it up to the engine and get it all the major components hooked up. The plan is to connect it to a battery so I can power up and check everything out and keep an eye on the fault codes if any appear.
I have lost count of how many hours I have spent studying the Yamaha wiring loom. Hopefully it will pay off and I've come up with what should be a viable method of connecting the R1 loom to the Mini ignition/power distribution.
After a few very cold evenings spent in my garage I have just about stripped everything I can from the loom and I have identified all the main components.
Progress with the R1 loom is being made. The picture shows all the wiring I have removed from the loom so far.
Items removed from loom
The huge task of sorting out the Yamaha R1 wiring loom has begun. I've started by removing almost all of the wrap covering the individual wires to make tracing and indentification easier.
The general idea is to identify all of the wires and then start stripping out the circuits that aren't required such as the lighting and horn.
To identify the wires I am using a combination of the official Yamaha wiring diagram along with the Haynes manual version for my 2003 5PW engine.
Once the loom is stripped back to essential circuits I will begin the task of converting it to car use such as disabling the lean sensor.
It has been a few years since I created the first Arduino speedometer and during that time I have improved my Arduino coding a lot as well as now having a 3D printer so I think its time to make some improvements.
I've just finished adding a programmable rev gauge to my carbon centre speedo. All the hard programming work was the handy work of Chippernut
I built v2.31 of Chippernut's project on a protoboard and decided to make the 7-segment display and rotary encoder removable.
Here are a few pictures of the build process.
I have been playing around with an Arduino for a little while now attempting to make my own gear position indicator and here is the almost finished product.
It consists of a 1.3" OLED mounted inside a re-purposed Smiths oil temp gauge that I picked up on theminiforum.co.uk for £10. I have gone down this route so that the gauge looks "factory" once installed and isn't obvious what it is. It will be installed in my carbon fibre centre binnacle.
