Lighter = Faster (N/A build thread #2)

[infernosg]

It's been a while since I've updated this. I had to pull the engine a couple weeks ago because it started leaking coolant when tried to fill it up. Apparently I forgot to add sealant around the threads of the engine studs, which isn't required if using tension bolts. I got that sorted out and put the engine back in last weekend.

I'm now getting very close to firing this thing up. The engine is back in the car and it's holding oil and coolant. I powered up the ECU and display and everything works. I calibrated everything except the fuel level input. I attempted to synchronize the engine and ECU but by then I think I drained the battery too much and wasn't getting any spark. I got one or two flashes from the timing light and then nothing. The steady-state battery voltage was 12.0-12.2V but I failed to note what it was while cranking. The cranking amperage must have been low because my display was resetting every time I hit the starter. I'm getting a good, steady engine speed signal so I don't think it's a trigger problem. I checked the IGN fuse and it was intact as well. I suppose I could have fried the relay but I put the battery back on a trickle charger and I'll try again tonight. If it turns out to be a battery issue I'll pull the larger battery out of the yellow RX-7 and try that next.
