Well I would take wideband reading over flashing lights any time...

Yeah, but flashing lights just add to the "p1mp Vt3c y0!" factor, and make you popular with the local crooooooze! And hey, both is possible!

A cable which will be going from the circuit to the 52mm display.

Cannibalized an IDE cable for that. I'll make the circuit board tomorrow if I'll have time.

BTW. I just bought a new downpipe flange.. So new downpipe coming sometime at the spring.

Slow progres.. again...

I got the circuit board ready. Now I just need to solder the components in place.

This also arrived yesterday:

Now it just needs some pipe welded on it.

Board is ready, though I don't know if it will work.

Hope so..

Leds are going to be like this:

That white one is not the actual gauge face I'll be using. I just used it to cut the holes in that plastic. Actual face will be black.

Some off-topic. I relocated and rewired my extra ECU and while at it looked inside it. I thought that it would be some home-built thingy but it wasn't.

Model is ER617 made by english company called ERL. On board there are trimmers with which you can adjust the duty cycle of injectors at several points. Cylinder number is also adjustable, it supports 4, 5, 6, 8 and 12 cylinder engines. I could also add more injectors to it as it can handle more than one. I was kinda surprised that it is so "advanced." Well not advanced in current day terms but advanced considering the fact that the car was built in somewhere late 80's/early 90's.
