Gotta show mistakes too! When we first built Rotaru, the 13B swapped BRZ, we had a hard time getting it to stay running. When I checked for good spark, as shown in the last video, I discovered the firing order was off. I had made the ignition harness from scratch and it turns out I made a small mistake. Surprisingly, it didn't make a huge difference running, but it would obviously matter for performance down the road. Our bigger issue turned out to be fuel related. More on that soon. Follow for details and feel free to ask questions!
