DIYPNP Setup - planning jumper route
Hey everyone, apologies in advance for noob questions. I'm sure there will be a ton of threads like this for all the MS noobs who picked up some hardware with the recent DIY FB deal.
So, I've just received my DIYPNP + Sequential Fuel Mod. The install is going into a 90 Miata, which currently has a 94 1.8L. I'm in the process of bolting together a 99 1.8L to replace it.
I'm *definitely* doing sequential fuel. I will eventually get to sequential COP ignition, so I need to reserve outputs with that in mind. So, the outputs I can think of that I need to plan out now are...
Fuel pump - high side switch, directions in 90-93 DIYPNP. Any alternative outputs I can use here?
Fuel injectors 3 & 4 - ALED / WLED according to DIY docs
Spark outputs 3 & 4 - PT7 and PT8 according to DIY docs
VICS - 99-00 DIYPNP example uses ALED
Fan control - 90-93 example uses ALED as well
Looks like PA0 is my only extra output signal on DIYPNP, so do I have to choose VICS or fan control? I guess I could use a "dumb" RPM switch for VICS if I *had* to. Well, and it will probably get a world-spec squaretop manifold eventually, so VICS control might stay in until I do COP / squaretop at the same time.
For now I plan on using the stock 94 CAS for sync, eventually jumping to the 99 sensors when I drop that engine in. As far as I can tell, no significant mods are needed to run the NB sensors.
Car does not / will not have A/C.
Car is presently N/A and will probably never need EBC. Will eventually be supercharged if anything.
I'm guessing I can pull 94-97 fuel and timing basemaps out of the 94-97 MSPNP to have something to start with.
And finally, given the requirements, what version of MSExtra should I be looking for? I'm cool with making my own MSQ from scratch if needed, I guess.
