Firehawk's N2 racecar project

[firehawk]

Ok, this project is slowly waking up from it's winter hibernation again. It is my firm intention to drive it around Alastaro circuit this summer and I'll be damned if I'll let anything come between me and my hachiroku again.

Anyway, I started by soldering a bunch of resistors inside the ECU to fool it into believing that the throttle position and intake air temp sensors as well as the idle mixture pot are still connected. I still need to get a decent vacuum signal into the MAP sensor but for now, I just made a quick'n'dirty solution of grabbing vacuum from the brake booster hose coming from cylinder #4. Probably not very stable but at least it's something.

Even after having stood stationary for quite some time, it was relatively easy to start the car. Start the pump, want until the carbs fill, blip the throttle a few times and crank - the engine fires up with a thundering roar. The ECU seems to work fine now, no CEL and the the alternator seems to charge as well now that I'd fixed the wiring. Our ignition lamp is broken so I'm unable to confirm if the ECU is controlling the ignition advance but once warmed up, the engine does, however, rev nicely up to redline. Still a bit of spitback from the carbs but the base advance may well be slightly off as well.

Lots of bits and pieces still needed to get the car up to a properly driveable condition, though - most notably a seat, a windshield, brake discs and pads and a fuel tank. Also, since I'm currently running a set of stock bigport cams, I'm on a lookout for a pair of 300ish duration cams and stiffer valve springs.
