New guy looking at MS for a 91
New guy here - I'm looking at doing the MS system as an educational project to play with. My car is a pretty much stock 91, but I figured having the MS in place and sorted out would be a good idea before I start adding things like a turbo kit. I've read most of the threads in this section and I think I have a good idea on what I need to do, but I just want to make sure I'm thinking straight so far.
I want to be able to completely remove the stock ECU and run everything off of the MS. I also want to be able to unplug the MS and re-install the stock ECU in case of emergency, or in case of a smog check.
I figure I need to:
Get MS1 v3.0 - w/ MSnS software.
Do the idle mod (either tip122 or the diyautotune kit) to control the idle
Get a throttle body with a TPS (not necessary, but I think it's a good idea)
I want to either use a PNP harness, or gut a stock ECU so the stock harness is unmodified, and the stock ECU can go in at any time.
Use the stock coolant sensor.
Use the stock IGN sytem to start with.
Control the fan, fuel pump, etc.
From what I see, this all looks doable, but am I missing something?
Also, what is a "CAS"? Crank Angle Sensor? Is the stock grank sensor and trigger compatible or do I need to do something different?
Thanks in advance,
