 Not too much progress to report, but a bit anyway.
The major activity over the last couple of days has been converting this thing into somthing useful. This is the entire loom from the bike, other than the tails connected directly to the lights and so on. It’s a lot more complicated than the equivalent thing for the CBR900. It’s also made doubly difficult to use by being set up to connect properly to all the sensors, and so on, when in the bike. On the bike the ECU mounts on the very top of the airbox and the loom wraps around the engine to all the sensors and so on. The problem is that the top of the airbox would be a daft place to put the ECU in the car. If I mount it, as seems sensible, on the scuttle then nothing’s going to fit any more. |
 So, I set about chopping all the bits I didn’t want out of the loom and lengthening and shorting various bits and pieces. I was surprised that Mr Honda has used nasty sticky loom tape on the loom and I had to clean a lot of gooey stuff off the cables.
When finished, it took me a couple of days, it was a lot smaller and lighter than it had been. Of course, I have absolutely no evidence that it works. I keep wondering about buzzing the whole thing out but that seems a trifle anal, even for me. The new engine loom is shown here. I’ve still got a bit more work to do though. The wires to the secondary injectors and the AIT (air inlet temperature) sensors are far too short at the moment. They’re the connectors just below the black and grey ECU connectors at the top left of the photo. However, I need to sort the airbox before seeing what to do about them. Those unwrapped bits of wire are to connect to non-Honda sensors on the engine, such as the oil pressure sender. I am going to need one additional bit of wire in the car though. The CBR1000 ECU controls the fuel pump through a relay. Normally this is mounted in the loom but in order to connect to the supply properly I’ll mount the relay on the scuttle. That will mean I’ll need to run a new wire to the rear of the car to power the pump with. Annoying as I was quite proud of the fact that the existing loom included absolutely all the wiring needed, even things like the wire from the brake pressure switch to the logger so that I can log when I’ve got my foot on the brake pedal. The final bit of news is that Bryn Jones sent me an email to tell me that the new tank is on its way. Hmm, it really is starting to happen. |
