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.

I wasn't happy with how the Innovate SCG-1 Boost Controller was handling boost. It made the turbo feel extra laggy because it would run off of wastegate spring for a while before it would open up the solenoid. Plus boost would fall off really bad up top even with me adding to the gain setting. What I did like was the ability to change the boost right from the gauge on the pillar but their are other devices that will let me do that. Here is the picture of the boost controller gauge.

I decided to switch to letting the ECU handle boost control. First I tried using the Innovative solenoid but it made this loud clicking noise unless it was fully open or fully closed. I switched over to the solenoid that I bough from DIYAUTOTUNE a while back. Here they are side by side.

I played around with the settings in TunerStudio a little bit and got the car to hold 13-14 psi all the way to 6500 rpm in 3rd and in 4th gear. Here are the settings I used.

Boost Duty 1

I will try this out for a few weeks and see how it goes. If I am not happy with it I will switch to boost by gear since I have the vehicle speed sensor wired into the ECU. How that works is that the ECU take the gear ratios that you enter for you transmission and is able to figure out what gear you are in based off of RPM and speed. Then based on what you set up as your target boost level for that gear it will shoot for that. I think a lot of people use that setting if they are getting wheel spin in 1st and 2nd gear.
