a complete explorer setup is really ideal.
and should be easy to round up in the end.
i have complete setups and need them or i would offer up. i have moved away from detroit so its not as easy to produce things anymore.
keep looking and you should be able to pull this off in a reasonable period of time with reasonable costs.
the stang stuff is definitely simpler, so it has a win that way, but its older and generally beat to hell. the tuners i deal with are getting away from them due to age related issues and harsh use in race applications...stuff starts to leak and corrode things internally on the processors etc causing issues difficult to track down.
this is why i would prefer a 2001 sploder setup over an 88 stang setup.
that and you can shitcan the dizzy and tuning and real time tuning capacity is easier with the later obd2 stuff.
it comes down to cost effective along with actual availability for me.
so my experiences and opines along with 50 cents still wont get you a cup of coffee, and can equally cause problems or solve them.
careful consideration of goals usually point the way to the best way to go.
lots of choices and lots of pros and cons.
start looking around and see what looks good.
