Commodore Thermo Fan Fixed

I've successfully fixed the thermo fan on the Commodore. It was just a power feed from the ignition relay to the fan relay, which was not getting power. Always look out for dodgy connections on these cars, I've found that over 12 years, some of the connectors have lost their shine and have a bit more resistance than they are supposed to.
So it all works now, I've botched it up, and I'm going to put a new thermostat in it tonight and solder the connections up properly.
I've also acquired a laptop which will serve as an ALDL interface. It's a bit better than what I had in mind ( and more expensive) but it's good really because it will be useful for other things. Laptops always come in handy. I will post the results of the ALDL analysis and some data streams up here when I've got all that happening.

Nissan Exa Turbo

My mate has a 81 Nissan Exa Turbo. It's an interesting car, if contraversial. Many people have a lot of negative things to say about the Exa, but I've found it to be quite a fun machine. It's very light, weighing in at 900kg, and has a lightweight engine, a 1.5 litre turbocharged unit that will have this little car torque-steering across two lanes in first and second gear. It's quite a lot of fun, beats any naturally aspirated 4 cylinder, and gives 6 cylinder falcadores a run for their money. The handling is good (as long as you don't have too much power on) and the build quality.... well, being an 81 car, it's a bit late to say anything about build quality, but all indications are there that is was pretty good from the factory. I wouldn't expect less from Nissan. The engine is fuel injected, which in my opinion is the only way to feed a turbo, and the turbo comes on at about 2000rpm, right through to the top. The wastegate is adjustable via a thread on the actuation arm, and with an intercooler, the boost could be easilly taken up from the standard 5-6 pounds (With the necessary extra fuel, of course).
I have heard of these things running 15 second quarters with a simple air filter and a decent tune. If my VP is meant to run a 15.5 in standard trim, then I believe it.

Thermo fan not working on the VP Commodore

Ever since I got this thing, the thermo fan has not been working. The thermo fan in this car is controlled by the ECU. The ECU reads the engine temperature via the coolant temp sensor. It uses this data to activate the fan at the correct time. The fan circut consists of a relay, drawing power directly from the battery to power the fan, and the relay is actuated by a feed from the ignition relay which is switched at the ECU, before going to earth. I've found I have no power from the ignition relay at the actuation pin on the fan relay. I plan on testing this tonight, and if this is not the problem, it has to be the wire back to the ECU. I don't care if I have to take the whole loom out. I will fix this irritating problem.
