Hello. I just received my Mega Squirt 2 V3.57 with Ford TFI Input and TFI Output, and the DIYBOB. I am hoping to start the install this weekend.
I have been reading through the online manuals and I am completely confused...
My vehicle is a heavily modified 1993 Ford Taurus with a V6 3.0, EEC-IV, TFI, MSD 6A, two wire IAC, MAF, Eaton Supercharger and various other sensors found in most EEC-IV units of late 80s early 90s.
#1 - Which ignition instructions am I to follow? TFI? MSD 6A? Both?
#2 - I have 6 injectors, the stock EEC-IV has 6 injector outputs. Mega Squirt only has 2... How does that work? How do I connect 6 injectors to two injector signals? Do I have to modify my harness?
#3 - I have two stock O2 sensors and one wide-band LC-1 O2 sensor. Only one O2 input on MS... What to do?
#4 - For the MAP sensor... Do I pull that off after the SC compressor (compression/vacuum) or before the SC compressor? (vacuum only)
Any advise and help would be great.
Thanks
Adam

One output goes to three injectors and the other to the other three. Best way to accomplish this is to split the wires where they go ingo the DIYBOB.#2 - I have 6 injectors, the stock EEC-IV has 6 injector outputs. Mega Squirt only has 2... How does that work? How do I connect 6 injectors to two injector signals? Do I have to modify my harness?
Either pick one - it's rare for one bank to be very different from another on a port injected engine - or add a second O2 sensor input mod.#3 - I have two stock O2 sensors and one wide-band LC-1 O2 sensor. Only one O2 input on MS... What to do?
After.#4 - For the MAP sensor... Do I pull that off after the SC compressor (compression/vacuum) or before the SC compressor? (vacuum only)
