So for those of you who have been following along at home, I’ve ordered a MegaSquirt ECM for my 99 Miata. The plan is to put a turbo on it, and MegaSquirt is the first major step. Actually kinda the last major step. Once you have standalone up and running, you’re pretty much ready to bolt on a turbo.
One of the requirements for a standalone is a Wideband O2. It tells you with a high degree of accuracy the air/fuel ratio of your engine. This is pretty important when you’re tuning an engine computer.
There are a variety of them out there and I almost went with the Innovate LC-2 ( https://amzn.to/38rAe0F ), but I learned the AEM X Series has a feature where you can connect it directly to the CAN input on the MegaSquirt, negating the need to set any offset for the Wideband, the MegaSquirt sees what the gauge sees. I opted for the version with the white face because 1. The regular version was out of stock, and 2. I ordered a white face Autometer Boost gauge, so I figured I might as well make them match. It should be delivered tomorrow, but I don’t plan on doing much until my MegaSquirt ships from Bofi racing.
