Megasquirt question for Eagle 3.0 conversion

[dmcman73]

Hi all,

I found a 3.0 engine that I am waiting for delivery on and I had a question that I could not find on the forums. I see that most of the Eagle 3.0 engine swaps are using the MS2 3.57, is there any reason not to use the MS2 3.0? The only differences I found is that the 3.57 is surface mount for easier mass production and the 3.0 is through hole components. I can save some money purchasing the MS2 3.0 kit and assemble it myself if it will work out for the engine swap.

Also, there are two MS2 3.0 kits, one has the MapDaddy4 upgrade. I don't believe that this is needed for the Eagle 3.0 engine swap, but, I just wanted to verify.

Thank you!

Functionally the PCB v3 and v3.57 are basically the same.

You would only need the mapdaddy4 kit if you were planning on 45psi boost. Otherwise you'll just lose resolution in your actual operating range.

You might want to consider Megasquirt 3 vs 2. v3 has nice benefits over 2 and will likely see the lions share of continued development.
If you want to stick with v2, I have an unused v2 aluminum case I can sell you

What does the v3 offer over the v2 when using it on the Eagle 3.0 engine?

It's a bit more future proof in terms of upgrades. I like the SD card logging and real USB connection. You can burn changes while driving without a stumble. I use the MS3+X module for radiator fan, AC control, boost control, water injections, and plan to add a radiator fan PWM driver and maybe PWM fuel pump control. Another owner here is running coil-near-plug ignition. The major options are listed on the product page:

If you want an ECU that just runs a base 3.0 engine MS2 is fine.
MS3 would let you skip EDIS. But I don't know if anyone has done MS3/Eagle so you'd be trainblazing just a little.

Thanks! I am still in the planning and designing stages as of now so I haven't decided on which one to start with. But this was all very helpful!

Luke and his pro-MS3 propaganda at it again!

I like the future proofing. MS2 & Microsquirt work great if you want management + a few extra features. If an owner is a tech junky that wants the opportunity to implement some fancier things, MS3 is the way to go.

I also don't like EDIS. "Here's your new & currently supported EFI & ignition management solution. All it needs to work is an obsolete junkyard-sourced black box"
