timing adjust

[hartwrenches]

Is there a way to advance the spark timing on a 94 2.3 with DIS, I understand you can advance the cam but that doesn't really change the ignition timing at least not on mine, only has crank sensor

as far as i know you can only do it with a chip.

why do you want to advance the timing anyway?

You have a cam sensor too.

No adjustments for the end user though. Its all computer controlled.

A chip, tuner, or physically move your crank sensor. Your 94 shouldn't have a cam sensor, so you could slot the holes on the crank position sensor to adjust your timing. I have never tried it, but it should work even though it is somewhat a shot in the dark as far as how much you should move it. Another possibility would be an offset crank pulley key.

camshaft position sensor. 1994 Ranger 2.3L :

Its up top opposite side the coil packs.

The link didn't work for me. I think the 94's in California had them but most don't. I know for a fact that my 94 doesn't. Starting in 95 they all had cam position sensors.

The cam sensor is the key. While it is possible to alter the base timing by mechanically altering the location of the cam in relation to the crank, the computer will try to compensate, especially with a cam sensor. For those who say it isn't possible, I can attest that it is, at least on those without a cam sensor (92 for example). I don't recommend it since the engine will either ping or knock depending on whether you advance or retart the timing, but sometimes advancing the timing will boost MPGs (very marginally). Do so at your own risk though.

The truck has 250000 plus miles on it and the engine is getting a little tired, on my older rangers I would just bump the timing a little and regain some power and fuel economy, just want to go 2 degrees or so with this one.
