Does advancing the timing on these computer controlled trucks work, and if so how well and how many degrees should i adavnce it. On my 71 442 when me and my dad advanced the timing after we recieved a new distributor it makes a whole lot of difference in the low end is it the same for my truck.

 

After reading some of the info here a couple of weeks ago I advanced mine on my '94 w/5.0 to 14 BTDC after taking the spout out and its made a hell of a difference-just wished I had learned about it sooner

 

what octane gas are you running with that timing?

 

It makes a difference and it's free. I couldn't find my timing mark, I found the scale but couldn't find the thingy to line it up with so I turned it until it pinged when I stomped it then backed it off just a little. I towed 2000lbs this weekend w/no pinging under load. It seems to even sound a bit deeper. But when it would lightly ping the first time I advanced it WOW. It would jump when I floored it. I am running 89oct gas. It runs better and now that I'm through towing I'm going to see if I can get a little more advance out of it.

 

Well, remember that you can also time an engine by vacume. Just simply find the point of highest vacume.

 

i advanced mine to 16° . i no longer have a ping

 

Donate,

On my '95 I can run 14 degrees year round like reg 87 octane. In the summer slightly more, but when we get the winter gas I will get a slight ping if I am at more than 15.

Haven't really hit the limits using the higher octanes, but at least 16-17 degrees BTFC on my truck using 93 octane. My truck seems to run a little smoother, and a little cooler on the 93. Performance isn't increased much SOTP over the reg gas, at least not that I have noticed.

Make sure to turn off your radio and anything else and listen for a ping. It only takes a very slight ping to cause the truck to pull out timing. In the case of the later trucks the computer will "learn" to use a less agressive timing if this occurs often. The ultimate goal would be to reach a point of max timing without a ping ever happening.



Injun Bill,

Glad to see you got good results. 14 degrees is also where I ended up on my '95. I played with 93 for a while but figured if I burn premium I may as well get a good chip and be done with it. My off idle response is much better with the advanced timing.

 

Since I had to pull the chip in my 300, I have the base timing set to 16 degrees advanced, and I use 87 octane.

Ford4Fun is correct about using a vacuum gauge to set your timing. That's how we always used to do it at the track. For you carb guys, the idle mixture can be set the same way.

Take care,

you sea level people suck, I can't take my timing near that far without ping.

 

Really? I've never lived at or tuned for high altitude, but I do know that less octane is needed. I would think that would enable you to run more advance than at sea level.

Take care,
-Chris

 

sea level you say lol im 8 feet below GOTTA LOVE NEW ORLEANS

 

Chris,

Is the stock 300 setting 10 degrees BTDC? Maybe the extra ratio in the tranny is helping some as well. 16 would cause a ping in my 302... been there done that briefly!

 

Yeah, stock is 10 degrees advanced. Maybe it's the gas around here. I have a friend who lives in Ojai (about 15 miles inland from Ventura), and his very built and modified Saleen Mustang supports 18* of advance on 87 octane, and 22* with 91 octane. I know how hard that is to believe, but it's true.

Take care,
-Chris

 

hey chris . does you mac support symbols? if it does try holding the alt key and pressing 0321456 on the side keypad . that should give you °
