 | |  | June 16, 2010 - One of the big roadblocks to the wiring was figuring out how to mount the massive ECU.
As you may remember, I was originally going to put it in the engine bay, but that was a pretty tight fit. I was also trying to reuse the stock bracket, and that was proving to be difficult. There's a bracket from the S10 or some sort of van that is a bit easier to mount in a non-standard location and arrangement, but I finally realized I could simply mount it with a solid strap, as seen here. It's solid and secure, but easy to remove when needed.
The ECU is located at the end of the passenger's footwell, which means the wiring harness can easily drop down through the hole that would have been used for the pedals in a RHD car. Cool. I'll probably put a plate over top of it to hide the ECU and give the passenger a good solid foot rest - but not yet.

As soon as I got home, I hooked up the laptop, fired up the HPTuners software and used it to turn off a number of vestigial appendages in the car's computer. VATS anti-theft: off. EGR: off. Air pump: off. Rear O2 sensors: off. Skip shift: off. A quick upload and voila. The car should be ready to start.
I should point out that this is pretty common software. Most shops that tune GM engines have a copy. I suspect my local machine shop would be able to do this for me. You can also send your engine computer off to have it done elsewhere - for example, Painless Wiring will reflash the computer with these sorts of changes for free if you buy one of their harnesses. The fact that I have access to the Flyin' Miata copy simply means it's more convenient for me than most people, that's all.
Another alternative would have been to build an inexpensive VATS bypass. The plans are pretty easily found online, or you can buy one pre-made. There are lots of ways to solve this problem. Since I also wanted to turn off a few other features, the reflash was the best option for me.
