MS3PRO EVO on 4th Gen 3sgte Options

[HardHead93]

I just got my MS3PRO EVO in for my conversion to standalone on my 4th gen 3sgte. I am planning on taking my time with this install to make sure all the wiring is correct and clean looking. To help with the install I grabbed a 5sfe ECU and mounting hardware out of a junkyard car to use as a template for mounting the Megasquirt into the car.









Got relays, distribution blocks, and different color wiring for a clean centralized install.




My goal is to wire the ECU up for as many features as possible and once I get good tune running, start enabling the features. I spent the last few days reading the instruction manual and it has me excited with how much it can do.

Just started the planning and laying out of the MS3PRO EVO. I spent time going through the ECU pinouts and mapping them to the proper connection on the Megasquirt. I printed out a picture of the stock ECU pinout and the Megsquirt pinouts and began assigning connection to each.


I also did a sketch of how I want to physically layout all the components and extra relays I will need.


I am planning to enable the following features on the Megasquirt outside the basic timing and ignition stuff:
- Boost Control
- AC Idle Up
- AC Cut under high load
- Intercooler Fan Control off Intake Temp
- Launch Control (2 step)
- Use the CEL light for warning of issues
- Possibly flat foot shifting (3 step)

I will not enable all these features right away but plan to wire them all up. This will let me enable them one at a time without having to pull the ECU out to do wiring each time. The MS3PRO EVO has the ability to do full 10 cylinder sequential ignition and injection. Since I only need 4 cylinder sequential, I have plenty of spare connections to add all the goodies and fun stuff.
