The is one thing that has been said here that seriously makes sense. NO its not hot! Yes the PCM can retard timing enough to lose power.
Yes custom tunes are the way to go, hypertech is not.
But the ONE thing that makes logical sense is maybe it is LEAN!! Ahh yes, now we have achieved clarity of thought, real reason, wisdom!!!!

I always thought it seemed lean. I put a free flow exhaust on it when it was new.
I always though it seemed a little lean. Then I put a cold air intake on it. that could lean it out more.
That is one of the reasons I put the hypertech on it was to regain the correct mixture.
Which works in the regular tune mode, but not in the premium fuel mode. That is where a good custom tune would come in, accounting for all modifications and accounting for lousy gas. The hypertech obviously puts more timming in it that this bad gas can handle and it does not allow for the timing to be retarded enough to compensate.
Thanks for the answer. Hats off to LX man 1, he got it right!!!!

 

Yes I think your the ONE guy here who got it right. Lean is the issue.

Thank you. Few words, right answer!

 

So you apparently think you know everything. (Despite still having a poorly functioning truck) Why exactly are you here again?

 

Wow.

Every canned tuning device I have ever read/seen/heard about specifically states that it should be used on STOCK vehicles.

And now you tell us you changed the intake? (if the so-called free-flowing exhaust is cat-back, it will sound nice, but that's about it - won't have any affect on power).

Call Mike and get some real tunes that will account for the modified MAF transfer function of your warmer-air-than-stock-under-the-hood-bling-intake.

 

The only thing that seems to be poorly functioning is your attitude. If you look through this post, you will see that someone hit on the issue, and I thanked him for it.

 

The only thing functioning improperly here is your attitude. If you would look through this post you would see that one guy hit on the issue and I thanked him for that.

I also have a 2004 f-350 v-10 that has a Hypertech max in it. When I pull about 10,500lbs on the 87 tune is pinges bad but when I run the 93 tune It pinges really really bad. Its hard to say How bad the spark nock is when its pinging that loud. So from what ive been reading the hypertech programer the pinging is normal. But how much can my truck take it or how bad is it for the motor? Anybody know?

 

Pinging is never good, it is pre detonation of the air and fuel mixture, meaning miniature explosions of gas and air before top dead center, which creates excessive heat and loss of power. To much of it on a long pull can and will burn a hole in the top of a stock cast piston (blown motor).
I do not understand why the 93 (92 octane is max in Oregon) octane is not better than the 87 though, that makes no sense.
I had to detune my Hypertech programmer to regular fuel, but I burn premium, no pinging and it runs strong.
Without the Hypertech the computer will retard the timing enough to stop the pinging and save the motor, but you will lose power.
My V 10 in stock form was fine with regular for normal driving, but not for towing, it always liked and needed premium 92 octane for towing.
Re set your Hypertech for regular fuel, but run premium when towing.
Today low grade fuel will not take the premium setting on Hypertechs programming, at least not while towing.
Some say they cant hear pinging or feel the computer retard timing in stock form, but some wouldn't know the difference.

 

The econ tune is the 87 oct and the high performance is the 93 or 92 oct tune. When I tow I have it in the econ 87 oct tune thats when it pings and I have run 92oct in the econ tune also but dont really remember what it did. I will have to try that again. But otherwise if that dosent help is there any other way or thine that will fix or help the problem. Or is it just the Hypertech programer?

 

Can you retard the timing with the HyperCrap?

 

Well if you have the Hypertech Max energy programmer set on 87 regular fuel setting and are running premium fuel 92 or better octane, and it is pinging badly, try re setting the programmer to the stock Ford setting. Use premium fuel 92 or better still.
The stock Ford programming will retard the timing enough to stop any pinging should it still occur.
If it still pings on the stock setting with premium fuel, find a good shop to take it to, you have a more serious problem. Towing with serious pinging/spark knock will burn a hole in a stock piston.
You can also us a quality Octane boost, but that gets expensive and is a hassle, and as long as you dont have the programmer set on the premium/92 setting, it should not knock on premium fuel anyway.
The V-10 will not run on the premium/92 setting while towing heavy, (not towing, yes) today's gas is just not good enough.
Also make sure your not using cut rate gas stations. Cut rate gas stations buy the lower portions of the suppliers tanks, that's one reason they get it cheaper. They can have a higher level of water and other contaminants in it as well.
If yours is pinging on premium with the programmer on regular setting, you may have some bad gas.
double check your programmer to make sure its not on the 92 premium setting.
Good luck.

 

Bottom line is that I don't think the Hypertech helped anyway. They might help knock of a few tenths off your E/T on the drag strip in a car, but for towing, it did not help my truck at all, it only added a problem.
Just set it back to stock settings and see what happens,with possible better gas.
Today's gas is just to bad to crank up the timing while towing heavy up hills.
I remember working in a Mobil gas station as a kid, selling leaded Premium fuel 100 octane for .32 cents a gallon.
Those days are long gone.

 

Actually, on my '01, the knock sensor logic only pulls 4 degrees off the timing. IIRC.

 

4 degrees of timing backed off, on a steep climb towing heavy at high RPM is significant.

I remember the old days when we had to do our own tuning, with timing lights and different points and different centrificul weights in the old distributors and set them up on a distributor machine to do what computers do today.

Even back then 4 degrees of timing was significant, both on the distributor machine and on the drag strip.
