need help tuning efi 347

[nigel]

i have a 86 5.0 5 speed with a 347 stroker kit, holley systemax manifold an throttle body an lots of other good stuff and it realy needs to be tuned better. but i never realy work on the new electronic stuff and i was told i need to get a computor program and a laptop adapter. exactly what equipment do i need to get the job done? any help would be great thanks.

First off, do you still have the factory speed density EFI? You could either get a Moates Quarter horse that goes into your factory computer, or do what I did on my 86 GT, get the Megasquirt PNP. The Megasquirt has way more features and can do a lot more stuff.

im pretty sure all the electronics are stock becouse the silver box with wires coming out
and the map senser both say ford on them. and what would more features do? all i need it to do is run rite

wher is the speed density efi? is that in the metal box

The metal box behind the P/S kick panel is the ECU (computer). If you have easy access, look at the end where the harness plugs in and read the larger, highlighted code - usually a mix of 3-4 characters and numbers - like A9L (89+ mass-air), DA1 (87-88 SD), or VR1 (86 SD 5-spd). You can also look at your throttle body intake tubing. If it runs to the air box with no intervening electrical components (e.g., a MAF sensor), then it is speed density (SD) and unlikely to run well with a typical 347.

Generally, the only SD computer that will accept a chip or the Quarter-horse system mentioned above is the DA1. I believe all mass-air (MAF) systems accept a chip/quarter-horse.

Can you post a pic of your engine?
