EDIS Heat Sink

I was wondering if the EDIS components have heat sink requirements. I figured to mount everything except theMJLJ V4 on the engine. Bruce Roe

I started using a very compact MAP sensor, an 8 pin surface mount chip with a small side port. I picked one that goes a little higher than 1 BAR, puts out about 4 V at 1 BAR. Cost $7.77 in small quantities from MOUSER; MPXAZ6115AP. I believe the technology is the same as automotive units. I use them...

I have built circuit to emulate the trigger wheel. However it was intended to allow bench operation of a system; a variable osc sets the equivalent rpm while a hand vacuum pump feeds the MAP input. It just uses several common CMOS counter & decoder chips, seems to drive the VR input OK. The EDIS cut...
