The GM HEI distributor requires a +5V source into pin B.
If Pin B = 0V then the HEI module control timing (ie during cranking), when set at +5V the ignition contol passes over to Megasquirt.

There are a lot of ways to set this up, you can:

[MSII, 3.0, v2.88, MT2.51, via Relay board]

I wanted to create a circuit on the Proto Area to use the Spare port for the Knock Sensor to control the +5V source required to an HEI distributor.
(I'm using the FIDLE to control Fans and am running an IAC & Ignition Control)

I've set up the circuit ...

Regarding the front panel express layouts, where's the hole for the MAP?

If a second MAP is fitted - I live in Switzerland and can get a bit high here at times, esp if off skiing - would that take up part of the proto area?

When ordering the V3.0 partial kit could I order a second MAP at ...

Is anyone looking to put together a 'Front Panel Express' design for the new v3.000 PCB?
