Winter Project - Megasquirt Build, Why work out in the cold? Options

[Tom Perso]

I just got my Megasquirt kit (stimulator, main board, and relay board) in the mail last week, along with a DIY-WB board.

I just got the MS built and working on the stimulator. Everything works great!!! I get injectors firing, FIdle works, enrichment circuit kicks in - it's cool stuff!!!

You can see in the pic above the Fuel Pump light is on and one of the injector bank lights are on. Cool stuff.

Now, I just need to get out in the garage and make the car fuel injected again....

Tom Here's something to think about. I would suggest mounting the ECU inside the car away from heat and dust. That you need to run a DB37 cable through the firewall. A DB 37 is a huge connector, if you don't want a huge hole you have to solder the connections in the car. Pain in the ass. Believe me you'll only do it once so plan your cable carefully. Here's my suggestion. Move the MAP sensor off the ECU board and into the relay board enclosure. Dedicate 3 of the ground wires in the cable to the MAP. It will keep the vacuum line much shorter and all of the sensors will be in the engine compartment. Rick You could do it Dave

Rick-

You could definately do it.

As for running a DB37 through the firewall - remember you don't need all 37 conductors....

Just the standard instructions for the MS are really very easy to follow, and the whole thing is set up so you can test the board after about every 20 minutes of soldering. After a couple of hours, the whole thing just works. It's a beautiful thing.

Most of the components have part numbers marked on them - the caps and resistors can be a little tricky, but help there is available via the ever-knowing google.
