This subforum's been a little quiet lately, so I guess it's my turn. I've had my M3 back on the road for around a month now. I decided I wanted to do things my own way (for better or worse). I am running a Megasquirt3. I wanted a standalone that I was comfortable with, so this is what I chose. Obviously Vanos and DBW has been deleted. I don't want to hear any bitching about that. I'm using VAC pieces for the delete's. I made my own simplified harness using the DIY Autotunes wires and the S54 connectors. VERY simple under the hood. I kept powersteering, but that's about it.
I wanted factory airhorns, but didn't want the factory airbox. I wanted to let the sound out! So I made my own airbox. It uses the original S54 airhorns (trumpets). It is still a work in progress, hence the bungee's. I'm going to make it a cold-air box at some point.
I do have the 6-speed from the E46 M3 installed as well. I bought the engine and trans and many of the mechanical bits for the swap from R3V member Lag. I am also using the subframe/S54 oil pan and tranny mount made by member TinyT here on the forums. They were both great to deal with.
I bought a welder and learned how to weld. My first welding project was the exhaust on this car. It has Ebay headers into dual 2.5" piping with an x-pipe, two bullet mufflers, and two Aerochamber resonators.
The whole project is still a work-in-progress, so please no nitpicking:)
I just got the GoPro, so the video isn't the best. I keep watching it for the sound! If you keep watching there is more than just pedal video.



Can you guess what the next swap is going to be?
