The wiring is now at a state where the ECU, GCU and dash can all be programmed etc. Obviously the map is already in the ECU but some auxiliary sensors needed configuring aswell as inputs from the GCU and outputs to the dash. I first tried to install the software for the dash, this all went well until trying to install the usb drivers! This then took about six hours. I have now worked out how to do it (the documentation just assumes it works)! Then the GCU. Once the ash had been installed the GCU usb drivers suddenly started working aswell. I think the dash had just messed everything up! Now the ECU. There was an instant problem with this in that when I plugged in the download cable it would connect and the disconnect continuously! A thought struck me so I disconnected the loom and used the dyno loom and all was well. I then thought that perhaps the dash was messing up, as it had caused a few problems already! I disconnected it and suddenly everything started working!

Monday, September 28th, 2009New Isolator and Extinguisher Wiring
Monday, September 28th, 2009Avid readers will notice the recent theme of all things wiring. And the saga continues! In a previous post I said I was using a really very nice small electronic isolator. However having tried to use them on the 935 a few things have come to light and we have decided to bin them and go for the more traditional type. This has caused a few wires to have to be extended and moved, but it should all now work! Yes it looks like the sort of thing you find in your fuse box but we have used these on the Lotus and they are really good! You can also see where the extinguisher control box is mounted.
Air Ducting
Monday, September 28th, 2009Now normally I would be VERY against deliberately making something that would have a negative effect on the aero, BUT engine life is more important. The current setup of the car means that the engine bay has no real moving air. If however there was some moving air causing the hot air off the headers to be blown out the back, and perhaps causing a little cool air to be blown over the engine, that would have to be a good thing! So, I have added a naca duct in front of the engine as seen below. This obviously removes some air from the floor but hopefully will help engine life and keep everything a little cooler!
