Need a tune?

[rangerdewd84]

I know this may be a dumb question, but I recently installed some late model ranger headers onto my first gen, and replaced the exhaust and went with a better flowing muffler. My truck is a 84 ranger with a 2.3l carbed engine ( just found out last night by looking up engine block casting numbers that i have a 2.3 and not a 2.0 as i thought). Is there some sort of tune i need to have done for the new mods? I know my truck has a computer, but I don't see any sensors coming from the carb, intake, exhaust, anything except for some wires leading out of the distributor.

Nope

Well someone has been swapping out parts before you got it, lol.

There should be an O2 sensor on exhaust, and temp sensor(2nd one, not temp gauge sender)
Also carb should have idle control solenoid and 3 or 4 more control wires.

Look here for wiring diagram for 1984 2.3l ranger: http://www.autozone.com/repairguide...DIAGRAMS/WIRING-DIAGRAMS/_/P-0900c152800781b2

once upon a time, the guy who had the truck before the guy I got it from, swapped a mercedes diesel in it then put in the 2.3. According to the VIN number, it did come with a 2.0l but the casting numbers suggest its a 85 2.3.....SO, i can put mods on it and not have to worry about someone plugging a computer in and tuning?

It doesn't sound like there is anything to tune, computerwise?

You still need to set base spark timing and spark advance.
And tune the carb
