Haven't read through the entire thread. But here's some more useful data about knock sensors.

sorry about that, I didn't realise the legal implications of improving upon what is supposed to be an open-source project. I neither have the ability nor inclination to make something this, I was just trying to contribute. Henceforth I will make no reference to megasquirt hardware on this forum.

I just came across this:

Owing to my extremely poor knowledge of all things embedded, I cannot figure out if this is something that works as an MS2 processor substitute ? Maybe not with the v3.0 board, but a different one

This should work, if at all, on a naturally aspirated engine only. Why do we need two separate sensors, one for MAP and one for barometric correction? With just one sensor: 1) Record barometric pressure on power up (everyone does this). 2) At pre-determined intervals, check if TPS = WOT 3) If TPS = ...

Damn Fred are you on this forum 24/7 or what :lol: How about this one instead of the 33810: MC33800 http://www.freescale.com/files/analog/doc/fact_sheet/MC33800FS.pdf?fpsp=1 You're right about availability though. The only thing I could find on digikey was the 33975. Its fairly cheap too. However, t...

Perhaps most people in the know would have already seen these, but I was on the Freescale website and saw some interesting stuff: MC33810 - Automotive Engine Control IC - http://www.freescale.com/files/analog/doc/fact_sheet/MC33810FS.pdf?fpsp=1 Talks through SPI, 4 drivers for injectors and 4 pre-dr...

I know very little about microcontrollers (i'm a mechanical engineer), and I don't have a better idea either, but I would like the team to clarify why this family and manufacturer was chosen? Was it a) Familiarity with the instruction set. b) Availability of a good low-cost prototype board in the fo...

Thanks....username is inline with your suggestions in the announcements section

The case is actually that of an OEM Denso ECU from an early miata.

This is probably decided already, but here's what I'm using on my MS: http://img378.imageshack.us/img378/5313/dsc00345mr3.jpg They're Tyco Multilock connectors with the following part numbers: Male - 26+22+16 pins - 174518-7 - About $5 each Female - 26 pins - 174516-6 - About $1.25 each 22 pins - 17...
