After almost a year, I finally had a chance to fire up my new engine project!
I'll start off by saying how easy it was to convert my GX200 to electronic fuel injection with the Ecotrons EFI kit. With this engine project, I wanted to use as many off-the-shelf and properly sized parts as possible. After finding the Ecotrons kit online and doing a bit of research, I decided to buy the kit since it came with all of the parts that I had a hard time making or finding with my first engine project.
There is no specific kit for the GX200, so I ended up getting a GY6 kit (including the throttle body) since I only needed to make a simple adapter to mount it.
The only other part I needed to make was a bracket for the crank position sensor. It is basically a 3" 'L' bracket that uses the magneto mounting points for positioning and a centered hole for the crank sensor.
I received a lot of requests to assemble a conversion kit after I posted the video of my first engine project, but the parts were all one-offs that would be very difficult and time consuming to duplicate. So, for those of you wanting to convert a GX200 (or other small engine) to EFI, I suggest that you to look at the Ecotrons EFI kit.
The kit overall is well built. The ECU and CDI are both potted, and all of the electrical connectors have solid locking mechanisms. Although the fuel pressure is fairly low, I would have preferred to have a barb on the fuel pump outlet and fuel. pressure regulator connector since I did manage to pull off the hose running to the fuel pressure regulator with only a slight snag. Other than that, I have had no issues with the kit. Support is also very good with Matt Lee @ Ecotrons returning my emails quickly.
