Why would megasquirt want to self destruct in this fashion?

Nice one though. Had me for exactly 1.2 seconds until I looked at the date.

What I intended to convey was that the stuff INSIDE the ECU should be controlled by key and not by CPU. In the diagram there are 8 relays, in two banks. The two banks are: 1) is key switched and controls various power feeds to the ECU and accessories such as wideband etc 2) is ECU switched and cont...

Here are a few interesting high side driver components to consider: ST Microelectronics VN5E160ASTR-E, SMD SOIC-8 package http://www.digikey.com/product-detail/en/VN5E160ASTR-E/497-11684-1-ND/2746913 Infineon Technologies BTS6143D, SMD DPAK-5 package http://www.digikey.com/product-detail/en/BTS6143...

There are way too many flavors of single IC for this application. But this is my preference... I prefer a more primitive design for such a primitive task. I like to use a double P-FET and 1 N-FET configuration. I know it is clunky with so many components, but it is easily sourced and will never obso...

I'll only take 1 board if someone else need it.

This is a pretty cool concept. It looks like it is still a work in progress and still buggy. But it looks promising and the interface looks fantastic.

Instead of 12 pots. How about 6 pots and 6 digipot and/or DACs? Preferably with I2C interface, so you can have multiple on the same control bus.

We can do the test with an enclosure if we have one designed. That would be ideal.

By having a spark from a BBQ ignition for the test, It is still useful even if we don't have a complete spec for the test. My initial thought was to hit various points on the board a few times and call it a day since the odds are low anyways. But if it turns out that the board is easily susceptible ...

I suggested a test that you didn't plan to include. I did all I was allowed to do before receiving the burden and useless award. I'd be glad to help. But it seem we have a big issue with communication and understanding. You already rejected the idea instead of putting it at the bottom of the queue. ...
