Megasquirt 5sfe Options

[Arsaces]

Hey guys, I have come across someone who is willing to part with a megasquirt for cheap. I just need to finish assembling it and make a harness for my car. My question is, how exactly does a standalone ECU like that do all the same things that a stock ECU does?

Do I need to pull the stock ECU's program off of it's ROM and load that into the standalone? My main concern is: will I be throwing engine codes all the time by replacing with a standalone? I know that putting a megasquirt on a 5s without going turbo might seem like a waste, but if I get it cheap enough I see no reason not to go for it. I also know that I will need a wideband, which I should be able to pick up for like 200ish.

Is anyone running a megasquirt on a 5s currently who has any advice to impart?

Also, yes I did use the search function, most of what I found was dealing with 3s motors. I will be updating this thread as I learn more about how this works so that others in the future can learn from it.

Thank you,
Nate

Read, Search, Google, Repeat. Remember, its just solenoids and coils...

It doesn't have to be 5s/3s specific.

Starting your modifications with a programmable ECU is not a smart idea. The ecu should come as your engine modifications exceed the capabilities of a stock ecu... because the ecu alone is going to make a minimal difference performance-wise.

Thank you Kwanza26, I think I just jumped the gun on the standalone thing. Someone offered me one for cheap so I wanted to see how much additional work I would be subjecting myself to.
