It's magic!

I've been running a 'blue' ignition box for a few years. Got it from the bay. I don't know what it is or where it came from. It works, the car ran fine.

I have a VDO white-face tach that I am fond of. The thing started getting flaky a couple years ago. The needle would jump around at lower RPM mostly and at higher RPM a good bit. When the car died, TU no start/run just out of the driveway, I found that the car DID start/run when the tach was disconnected. OK. My used-to-be-flaky tach has a real problem.

My blue box died recently. I put in a Standard LX-101 box I got from the bay. The module came in a Standard box, has a Standard label, probably is a 'real' Standard module.

Car starts/runs fine.

BUT...my MAC Tools ignition tester said the spark is a bit hotter. I've never trusted the MAC tool to do anything but tell me 'something' is in the wires. Still, the higher readings piqued my curiosity a bit. I hooked the VDO back up: It's perfect. Solid as a rock.

I tried for months to find someone to 'fix' the VDO. A repair outfit VDO referred me to didn't bother replying to any query. A second repair outfit said it would cost more to fix it than to buy a new tach. That tach isn't available any longer.

I've run with no tach for years...and it was the ignition module?

That's my story. At least for this afternoon.
