It is. Got terribly diss appointed to learn all the upgrade needed, not counting a tune. Now am just buying pieces till I get everything. Next month it's the regulator and fuel meter, then more fittings. Got rails and some fittings already.

Just to the factory line connection for now. Bout $500 for the rest minus rails and tune.

Re: Knock & Ping question

Got my 91R tune flashed and drove about 15 miles to get here warmed up and idling correctly. It seems like the pinging is gone. When its hot outside, that should make it easier for detonation to happen, correct? So, I'll goose it tomorrow on the way home cause I think it is supposed to be ~90 again. Wish me luck!

Change your pcv valve and fuel filter

I did the fuel filter about a month ago. I think I'm gonna change the PCV valve this weekend. Aside from injectors, it's like the only thing I haven't done yet. I'm thinking about getting one of the pre-filters like this...

Also when you test drive in warmer weather. Try to load the engine. That is when the pinging will most likely occur. For example: put it in 4 th gear and drive about 20-25 mph and mash the accelerator. Or put it in high gear cruising up an incline. Etc etc.

I saw this post when I was at Starbucks so I tried it. Cool, good so far. I'll try it this afternoon in the heat too. Thanks dream!

Would an aftermarket A/F gauge work good for detecting detonation before it happens?

Really your knock sensor should "detect" it.

But a wideband is definitely a good idea to make sure your tune is spot on.

Makes you wonder if I'm hearing pinging that is caught and reduced to a harmless amount by the PCM or is it just detected.

You know that tingly feeling you get when you think your about to be rear-ended? That's what I felt when I heard the little marbles in a glass sound.

Somebody in the big house may get that feeling too!

Crap! It's still pinging with a 91R tune. I guess will need to data log WOT. Has anyone data logged with the SCT tuners?

it maybe time to check fuel pressure. if you dont have adequete fuel in between each stroke the fuel will not be able to cool the top of the piston before fire.

Are they the shrader ports up by the fuel rails?

Yes.


Detonation is when the ignition fires to far before the piston is up to TDC.
The higher octane fuel is slower burning so it helps to prevent this and allows for more advance to be added. What you are hearing when it happens is the piston shaking and rattling in the bore and it can also burn a hole in a piston because of the intense heat generated and the crankshaft pushing the piston up into it instead of allowing it to go away from it.


Even more scared now? Don't let it happen very much.


I wonder if you have a timing issue with the "stock timing setting" and that the "tune" is actually advancing it to far?
Put a light on it and see exactly where you are at.

yeah maybe you should load the stock tune in and keeo the premium fuel in until you do some more testing.

It's doing it on all the tunes, aside from stock. I didn't drive it on the stock tune w/o the chip. I guess it would just be w/o the fix for my gear change. It really does it at ~20mph in 4th in WOT. I'll need to pickup a light as my old one died years ago. Bummer! I should be able to find the base timing in my chiltons, right?

I decided to flash to the stock tune. I took it out for a test drive and didn't hear any pinging at WOT. Its cooler outside so I'll check again tomorrow afternoon in the heat. I feel better now, but I'm disappointed. I feel like I've punched my Mustang in the gut a few times

I hope Bama can give me some information about what is altered on these tunes. I'm sure it's not just timing alone. I want to see if they can make the basic street tune essentially just something that adjusts for the gear change. That way it will be like basically a stock tune, but with an accurate speedo and proper odometer increase.

I've been looking on google and in my chiltons, I don't see anywhere that shows how to check or set base timing. I think it might be set when you install the cams and timing chains.

I've heard of bama maybe have a bad tune or so. But its wierd to have 2 in a row. you don't have a distributor right?
And did you say you have proper fuel pressure?

No on the distributor. I think I can pickup a gauge and connect to a shrader valve on the fuel rail passenger side. My chiltons is pretty lame. Not much on checking fuel pressure.

Re: Knock & Ping question

Most chips are burned assuming you are at stock timing, so if it had been advanced before and the chip added even more it is hard telling how far advanced it really was.

What year is your car?
When I get a few minutes I'll see if I can't find something on setting the timing.

2004 Mach1. It has the 4.6L DOHC.

Ok , my oldest daughter has one of those, so maybe she actually listened to me and bought a Chilton's for hers that I can use.

It uses a crank position sensor correct?
Is there any adjustment to the sensor or wheel it reads from?

I'm not sure on that. I think the crank sensors are under the intake...?

I think that might be the cam shaft sensor. I see in my chiltons where the crank shaft sensor is now.

Yes, it should be on the lower front of the engine close to the crankshaft pulley.

I ask whether it is adjustable or not because the MSD add ons are and you use that adjustment to set your timing on the Fox Body 5.0.

Found the camshaft sensor. It's behind the power steering res. Still trying to locate the crankshaft sensor.

---------- Post added at 12:57 AM ---------- Previous post was at 12:51 AM ----------

Okay, think I've found it. I had to jack the car up some to get my bigness in there to see it. It looks like the pic in the chiltons.

It's hard to tell from the pic. But usually it Will be very close to the crank/pulley or harmonic balancer.I'm talking like 1/8th inch away.

Here's what it looks like off the engine.





I was hoping that they were adjustable like the MSD Crank Triggers, but it appears that they are not. I suppose you have to time them with the chain and gears?
Does your manual tell you how to set the timing?

Actually trojan. Isn't there some sort of chain tensioner in there?

Are you thinking that someone degreed them to much?

I'm suprised no 4.6 guys hopped in here to lend a hand yet.

Yes there should be and, yes I am wondering if someone advanced them previously.


Me too, I wish they would jump in, I'm foundering here from lack of experience.
I have tons of books, experience and info to draw on for our Fox Bodies, but next to nothing for the newer Mustangs.

I wonder if there is a way to tell by connecting to the OBD2 port? There seems to be a ton of info provided, as long as you have what is needed to read it. I can ask Bama what they think as something like this (timing adj by chain) surely has happened as long as the 4.6L has been around.
