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.

CELEBRATION!!!! I got the Celica to start and idle with the MS3PRO EVO. I wired everything up and spent the last few days hunting down issues. PitCelica, thanks for the help. Without your wiring diagram I would still be banging my head against the wall looking for problems. At first I thought it was my wiring, but after reviewing pitCelica's wiring diagram, I was good in that area. I knew it had to be something with one of the settings in TunerStudio. I am not used to so much control in the software. When I was using the DIYPNP it was simple and post changes were made to the hardware (circuit board) not the software. Once I figured out that my MAP sensor was not calibrated correctly and my injectors were firing out of order. . . VROOM! It started right up. Now I am dealing with the engine running lean. I think I need to do some adjustments to the injector settings (Voltage and Dead Time). Also, I still need to ensure my timing is not drifting. Still a lot to do but I am 1 step closer. Once I am close to done, I will post my TunerStudio settings as well and an ECU pinout wiring.
