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.

Since I am planning on getting the car tuned soon, I thought what the hell, put bigger injectors on. This will future proof me for if I want to run a different turbo or convert to flex fuel. I know I am planning to do a SWEET CT16 upgrade some time next year. The stock injectors can handle that turbo upgrade fine but it puts it up at 90% duty cycle. After doing some research I found it it not good to consistently go over 80% because it over works the injectors and can lead them to fail sooner. I decided to go with 850cc injectors, I remember reading somewhere that the stock fuel rail with a Walbro 255 fuel pump is good for up to 800cc injectors. Since I plan to stay below 80% duty cycle, I never plan to max out those injectors.


Here are some shots of the new injectors side by side with the stock injectors.




It was a pain in the butt getting those things in. The first couple times I put them in they kept leaking at the seals. After dipping all the seals in fuel and wiping out the holes in the cylinder head they finally went in right and sealed properly. Another one of those quick swap jobs that wasn't so quick.

I made the changes in the TunerStudio software and took the car out on the road. The car drove great!
