Time to finish detailing the Microsquirt install.
Microsquirt needs a variable TPS. If you have an automatic throttle body you can use the 6 pin tps already on the throttle body. You can use any variable TPS you like really. You just have to calibrate it on tunerstudio. I choose to use a M50/52/60/62 TPS. They are cheap and really easy to go to a junkyard and find half a dozen.
I bought a squared motorsports TPS adapter plate. I kinda wish I made my own, its clocked kinda weird. I think it's made for an M20 application.
I am not actually running a idle valve at all. My idle is controlled by a bleed valve from a euro m30 2 wire ICV.
The valve is just inserted to the hose where the ICV would normally go.
I may run a ICV later but this seems to work for now.
I used the open hole on the intake tube to insert the GM iat sensor. It fits pretty good.
You can use the stock motronic coolant temp sensor. In fact the calibrations are already pre loaded into tunerstudio.
I chose to leave my FPR un plugged to keep the fuel pressure stable at all ranges of rpm. Because my fuel table is infinitely variable I didn't think having the fuel pressure fluctuating would help with tuning.
Plus I need a intake manifold port for my map sensor. My map sensor lives below the relay box on the drivers side inner fender. I inserted a .030" might welder tip in the map line to smooth out the signal at low rpms.
After I had all my connections completed I began trying to wrap all those ugly wires. It's not the prettiest but better than nothing.
Here is how she looks right now.
