If the SES light stayed on for 12 miles, that sounds about right for the P1211 code - normal for a chip, stock injectors & stock HPOP.

 

I much prefered the shifting of the PHP PMT1 tow tunes, on PMT2 pcm.

 

WhiteB, thanks for responding.

Well the filter minder light didn't come on until the very last 1/4 mile of the very last drive when I switched it into 80hp daily mode.

If the PCM and chip are having a poor contact, why would the 80 hp daily tune shift fine and the 65 hp daily tune shift poorly?

I did double check the PCM and Hex Code...and all the tunes have the same HEX Code...so I don't think I screwed that up.

 

Is that an HPOP related code?

 

Yes it is. But I would start a new thread - you'll get alot more input.

Basically what happens is this:

If you had a chip with your stock split shot injectors you would see this as the stock HPOP would not be able to keep up with the demand from the chip. The Pressure would slowly drop off and the duty cycle would go over 60% and trip the check engine light (P1211 code). This is what most of us experience with a stock HPOP & stock Injectors with a chip. Something similar to this:

Pressure starts to drop, duty cycle goes up and soon the SES light comes on......




But, like I said - without knowing the exact codes your truck has it's basically an educated guess. Very common to have this code and an over boost code with just a chip on a stock setup.

If you have a completely stock truck with a chip I would not be pushing it or getting on it at all until you install gauges (EGT & boost at least). Especially with a stock exhaust - you are going to run hot if you ride her hard. Your adding fuel right now but no additional air and not allowing the exhaust gasses to escape any quicker.

1. gauges - EGT, boost (and/or fuel pressure & tranny temp)
2. Upgrade the air intake (Ford AIS, 6637, AFE, etc...)
3. 4" exhaust (MBRP - good deal with Riff Raff)
4. Boost fooler - if the PCM detects an over boost condition it will set the SES light and defuel.(Driven Diesel Overboost Annihilator)

 

Not saying poor shifting is from a bad contact - what I'm thinking is a poor connection between the program selector and the chip could by why you're having difficulty changing programs. Then you had a check engine light right at startup after installing - so I'm guessing poor contact between the chip & PCM.

 

REWIND....why the $&% would they sell tunes for a stock truck when they know its gonna be causing check engine codes?

• EGT gauges x2 and HPOP fuel pressure gauge arriving today.
• Larger air intake clearly is needed for 80 hp tune. Ford AIS cannot handle the air required either...as others have told me the truck filter minder trips with 80hp tune with FORDs AIS system.
• The domino effect of $$ spending begins...uh!

 

yes it has - welcome to "PMS" Powerstoke Mod Syndrome.

Well to be fair - any "off the shelf" or "custom" tune will set a check engine light in this type of tune. As far as the SES light goes - it would happen no matter what chip/tunes you would have bought. And you kinda jumped the gun a bit by throwing the chip in before the gauges, Air intake, and exhaust. But it's all OK - you just need to catch up a bit.

P.S. The Ford AIS works well after you drill a 3" hole in the side and added the fender sleeve.

 

I'm happy with my Hydra. I've wondered if I could use my Edge CTS monitor to control power levels instead of the supplied PHP display to clean up the cab a little???

 

Trekbasso,

My bad... EGT's are not an issue for me in ANY tune/tuner. The highest I have seen is 1200 and that was in the 100hhp PHP Perf tune on an extended WOT run. I say extended but for me that's not much. I'm not that hard on my rig. Normal driving and getting on it I see 900 to 1000 degrees max with Gearhead and PHP. I have a heavy foot just not a WOT heavy foot.

Tow tune shifts get up to around 2400rpm between 1-2-3 which keeps EGT's down and the boost up between shifts.

My max boost is about 24psi with my Van Turbo. I think I have leaky exhaust manifolds that are causing lower max boost numbers but that;s another nightmare.

8 Bales at 1500lbs ea. I estimate about 21K total. I didn't see over 1050 degrees pulling this load.

I just want the truck to shift like in a decent and safe manner and I don't wanna se check engine lights.

Is that too much to ask?

Before I jump to conclusions I am going to get the codes and see what the story is.

But if the shifting in 65hp continues in this fashion, I will not stay with PHP tunes.

 

You have to go to PCM 101 to understand how the PCM works.

Here is a quicky-

Ford Engineers who developed the PCM set parameter "alarms" to go off when those parameters they preset were exceeded. The effect is the SES light coming on. To eliminate the SES light constantly setting with aftermarket programming those preset parameters needed to be raised or set higher so they would not constantly get set. Mostly those "soft codes" do not have any merit and are just annoying. We only do 3 "pesky codes" so they are not constantly set during normal operation of vehicle. All other codes are needed to be able to help diagnose any potential issue. This is why scanning for the codes is essential.

I hope this helps.

Well install the boost fooler to stop the overboost code & defueling.
As far as the P1211 code goes: either go to a lower power tune, upgrade your HPOP or go with single shot injectors.

As far as the shifting is concerned - try a different program but you will find out that most will recommend at least a valve body upgrade. You can do it yourself with a kit or buy one from BTS or John Wood.


it's all part of the journey you just set sail on.........sit back and enjoy it........

 

no no no...stop....my ears are covered...I don't hear you....lalalalala...

Listen Mr. Albino Buffalo Man...I don't wanna go down this road. I don't wanna spend thousands more $s.

I just don't think the 7.3 in stock condition is a REASONABLE truck to drive. Its painfully slow and lethargic. My own 7.3 and and others I've driven. I just want something a little more spritely.

The 65 daily hp tune is perfection for my hauling needs. Just enough power...I don't need more. I do however need it to shift normally.

 

Slow down a bit here... many people are at work and don't have the chance to contribute yet.

Who's tuning? If it's PHP tuning, what hex code and tune did you select? It's easy to miss a spot on the edge of the PCM and cause issues. We don't know if you're getting an overboost and it clears in 90 seconds, or if it's a full-on SES.

The AIS can take what the stock injectors dish out... you might have something else at play.
