Timing bump a 96' OBD2?
I've manually, further advanced base timing on many a OBD1 F-150.
However, I have a friend w/ a 96' OBD2. Initially I said no. But he has a distributor / a single Coil & a SPOUT Plug!
Anybody knowledgeable regarding this?

I'm heavy into 87'-95's. After 95's they become more a mystery the newer they get.
In fact, did I dream coil packs in latter years? If not, what year did F150's change over to them?
Thanks for the replies! This is where I come for my F150 schooling.

I'm guessing as long there is a distributor & a single coil. Coil Pack's (I think they're referred to) would be the deal breaker?

The Explorers may have used coil packs while still retaining the 5.0L engine. Not certain about that....

So no more manual base time mods after coil packs replaced the distributor? After that you have to chip or flash the ECU to play w/ the timing curve?

I want to say based on what I know (and its been a while since I asked any of my mechanic friends) but with the COPs (Coil Over Plug) you will have to program the ECU and mess with that...but I may be wrong, I don't mess with the 97+ engines all that much to be honest as 96 and pre 96/95 was the time of simpler engines and I perfer simplistic engines to the OBD2 things that make it more complicated even tho ODB2 is better for tuning and accessories (newer standard) ill stick to older reliability of pre 96

Once the manufacturers started using internal crankshaft position sensors there is no easy way to advance the base timing. A tune/tuner is required.

Yep I like my 87' OBD1. Only has 87K original miles. I'd reeeealy like it if it was MAF rather than MAP & SEFI rather than EFI.

I tried bumping timing on a 96 5.8, 14 deg first then 12, eventually went back to 10 (stock). It would ping anytime with heavy throttle in 4th gear (E4OD). I read one post that said timing maps were different on OBD2 engines, I do know the 5.8 doesn't have a knock sensor as the 5.0 does. Some apparently did the bump with good results and no issues. Didn't work well for me even with 91 fuel.

(The increased gapping from stock, in addition to the side gap mod loves 87 octane, but the engine wont even try to start w/ 91 octane)
No sign of ping under load. Great Hwy MPG. I did some engine prep first.
Descaled & flushed coolant. 180 thermostat. New O2. Seafoam treat, including De-sludge engine. Remove combustion chamber build up. Then Lucas injection cleaner every 4-5 tanks of gas. Went all synthetic fluids. K&N drop in air filter.
Timing bumps should never be attempted w/ any active or continuous memory codes present.

I did a GOOD seafoam treatment thru intake via brake booster line, also used water the same way. Neither made any difference, so I'm convinced it wasn't a carbon buildup issue. It was much more responsive at light throttle, but the pinging wouldn't completely go away even with the higher octane fuel. 33" tires and 3.55 gears probably didn't help much either. I also own a 96 GM 5.7 that unlocks the converter LONG before the Ford would under same conditions. Much better powertrain mgt in my opinion.

on the same note I just want to ask to be sure and also to get this info posted (hey why not its on topic 
) if im going to bump the timing to 14BTDC will I need to mess with any thing else like the cam, plus, valves, ect, ect, ect I read about the 6L tune and want to see if I can do the timing change with out having to mess with other things/reprogram the ECU or what ever is in the 5.0L trucks (i would assume theres an ECU in these things...) cus im thinking of getting the truck tuned up soon and im thinking of bumping the timing to 14BTDC when I go to get new plugs and do the tune up...
