Jimstim is complete, and the Megasquirt base is done. Miata and MSM mods not yet done, but I'm going to take a bit of a break from the electronics to get back under the hood.
Also, my O2 sensor arrived, and will go into the car as soon as I have the time. I'm looking forward to getting some baseline data on how the car really runs unmodified.
On building these things on your own: the Stim took about 3 hours (and counting, as I'm modifying as I test the megasquirt), and the MSQ has taken about 8-9 hours so far. Research has taken probably more than 40 hours all told, and I'm still looking stuff up. Oh, and building the harness will be a couple of hours. But it's all very rewarding - every time I test out a set of components, and they work (or don't work, and then I fix it), I get a little thrill, and understand a little bit more about how this thing will work once it's hooked up.
Last weekend I tried to install the Begi Separated Gases Downpipe. What a pain! I drive year round, so corrosion is an issue, even more than normal. I got two of the four heat shields off in 6 hours, and had to stop due to time limitations. Next time will be much quicker getting to that point. The big slowdown was figuring out how to remove intake, strut tower bar, washer fluid, and various other things to get into the exhaust pipe. I'll try again next weekend (and the downpipe has the O2 bung for the wideband sensor).
Today was spent mostly with my motorcycle, getting it ready for spring. However, I also installed the TB inlet tube and Forge Diverter Valve. Two lessons learned:
1. When installing lots of things, do them one at a time and test before doing the next. The inlet tube had a loose clamp that I discovered while driving, but I didn't know if it was the tube or the DV. Small, but a good reminder.
2. Traction is going to become an issue. With the upgraded tube and DV, 2nd gear pulls on the street are breaking my rear tires free. I'm still on the 5 year old stockers, but this is a new phenomenon (with only 2 non-power producing mods!)
