The the pcm does not automatically adjust the transmission shift point according to the changes in HP. Neither does a chip for that matter. The adaptive functioning we are talking about is related to the engine. You can change the shiftpoint via the reflash if you wish. As a matter of fact, if it is controlled by the pcm, you can alter it via the reflash. BTW, the reflash also cannot cook, clean and definitely does not do windows.

If you change the pulley the computer will adjust to try and reach its A/F goal. It does this based on the air density measurement. It determines air density by averaging the MAF and ACT readings. It knows, without sensing via the O2 sensors, that it is reaching this A/F goal at WOT because the tables are setup to result in that goal based on the setpoint it begins with. It begins with a particular setpoint based on the air density measurement. In other words, it gets the A/F right because it knows that the tables it selects will make it right. (BTW, this has been explained several times. You guys questioning this really need to read the posts instead of clicking "reply" so quickly.)

It naturally follows that it depends on the data to be correct. And that is an important point...

Sal, based on your paragraph regarding the previous activities of who you "think" is doing the reflash - you are mistaken about who is doing the reflash. Big time. The person doing this is an expert in the field. It's someone industry insiders go to with their questions. That's one reason why the tables on Onefastlride setup resulted in a steady A/F reading, right out of the box, with no tweaking. The data IS correct becauset this guy knows what he is doing. It's not some guy traveling around doing things here and there.

Damn Jim, im surprised you havent turned blue and popped yet. You have repeated the same information i dont know how many times now

At any rate.. The tables that are being discuss are modified BASED on what YOU have. If you set yourself up for a 75 shot of n20, 4# pulley, cold air intake of some kind, accumulator, catback, headers, ported heads, cam, or whatever else you have on your truck, the tables will be modified in those directions to take into account for what you have. If you challenge common sense and up the shot to 200 hp and throw on a 8#, yea, youre going to have some problems. You have some head room to work with.

Since the majority dont have a built shortblock, you cannot ask for a better $250 spent. Youre reflashed PCM will take all you can throw at it before your rods / block self destructs because of the power limitation.

The guys with the built block running a lot of boost and juice have to think about how much boost they might increase in the future or more nitrous they plan to shoot. IF you think ahead and have all of these variabled accounted for, you will have headroom as well.

The most important part of this whole reflash snakeoil, is that you will be running optimum a/f and pulling a lot more power then these chips since the computer is controlling the timing based on variables its receiving in real time. Not based on the fixed timing and set a/f.

 

I understand the reflashed computer being able to calculate A/F based on air density, but what if you take away one of the two sensors that it uses for this calculation? What I mean is if you have a beast that is maxing out the MAF at 5.0 volts that leaves you with an IAT sensor. What does the computer use for calculations then? Does it then switch to a set of precalculated tables based on RPM and TPS ?
Thanks Dale

 

Not trying to flame you here, but that above statement is totally false.

"it knows" ??

How does it know?

How does it know that you dont have a bad coilpack, stuck EGR valve, bent intake valve, broken valve spring, clogged converters, or even something simple as a clogged fuel filter?

The reason that you are repeating yourself over and over again in this thread is because you make statements like the one qouted above.

And its IAT, not ACT. Our sensor isnt an Air Charge Temp sensor, its an Intake Air Temp. there is a difference .


Keep in mind that I am not attacking this whole "reflash thingy", I am only pointing out flaws in the information being given here:fyi ,but from what I can determing from the misleading and incorrect info being given here in this thread, it sure is sounding more like an infomercial that is making claims that it cant support.

KEEP ON TRUCKIN

 

I'm not sure what exactly you people are looking for. Be specific. So far I came up with the following results people are looking for:

- Does it work?

- Drivability
- Everyday driving

- Adaptability
- changing pulleys
- nitrous
- weather

- Dyno Results
- A/F
- HP Gains

I'm ofcourse going to be testing all of these. This will be starting today or monday. Most of these questions can be answered just by starting and driving the damn truck. They should have already been answered when the author of this thread posted as far as, "does it work?" It's seems thats what most of your questions ask no matter what form they are in. Well, obviously it does work. I think some you folks are wanting too much information. Most of it was answered in the first thread. The fact is there is only one man that knows every single why, how, what facts that you are pondering. And guess what, it's going to stay that way. How many of you guys nit pick to Sal, "i want to know every last parameter, map, programming, 0101 code that goes into your such and such file." I don't see that. 99% of you order a chip and give a rough description of a magical wish list, send it to the tuner, the tuner to the best of his abilities translates what you just said into technical jargon and make it work. You get it in the mail, smile and slap in the chip. "Hey der fellors it werks great". None of this "well, it werks great, but galleee, how der dis thing works ,REALLY?" "they have some lil munkey write'n code in this here thang with connactors, well gee , hrmm, i wunder" WTF... it works DUH! Sal doesn't give out all his magic, nor JDM. Gees.

If you want to know something specific about driveability issues then list them in the thread linked below. I'm not going to do irrelevant track times, or intake temp bs. I will give my honest oppinion as a consumer and enthusiast about how this new fangled thing works, and my thoughts on it for the L community. Not one person here is going to beable to fully understand and know how it works except the one person doing THE reflashes. What, you going to go buy your own FORD widget to reflash your own computer? You going to get info about a pair of sneakers from someone that makes horse shoes?

list what you want to know here and I will answer it best I can:

"performance" dealer in Atlanta. Asked the "expert" who tavels all over the country, plus some others. Reflash will give you enhanced performance, but as I stated in my first post, ALL MODS MUST BE SPECIFIED/INSTALLED AT TIME OF TUNE! "Adaptive" capabilities are very limited--like going from hot to cold weather. Will NOT compensate for larger pullies,etc! Hope the brave sould who ignore Sal & others will be honest to post when their engines go boom!

 

Maybe with Jerry's software, but not the dude doing reflashes for BOP. I know Jerry and he has some amazing knowledge and tuning abilities. This isnt the guy who is doing these. Talk to Mark and he will tell you EXACTLY what Jerry thinks about it. Its more then adaptive limited.

 

just for FYI, sal already explained why the reflashes wouldn't do as claimed in the other thread, i don't think he feels like doing it over and over,

and as was said, you can reflash and get power, the simple fact is, it won't be any more productive than a chip

 

Since when was Sal a powertrain engineer for Ford and Roush?

 

Do you honestly believe that all the major tuning companies have engineers who can't write software that can actually manipulate the necessary data within the pcm? Oh come on! This is what these companies do for a living. With some background training in computer science, nearly anyone can hack away at code, figure out how it operates, and how to manipulate it successfully (and even then it doesn't require a degree or any school training).

Why don't you get this "dude" to post for you, instead of you pretending to know what you're posting from misguided received info, or illogical make believe scenarios that you've been mouthing off.

Edit: Within 20 min. someone from "TRF" (Team Re-Flash) will retort.

 

Careful Doug, if you ask for any credibility of the person claiming that this IS the greatest thing since slice bread, you will be personally attacked as I was in the other post.

 

Oh boy - Im in real trouble now... Grey 03 and I agree on something..... Damn.. LOL

**** - Since it has become clear that you have a financial interest in this technology it would be inappropriate and a violation of the Vendor rules here for you to continue to pump the product.

I'm sure a man of your integrity would honestly reveal his interest in a product that might influence your statements.

Doug

 

Hey Doug. You say it time after time, their are two sides to every story and not to post untruth. If i have a financial interest in this, why is it im not setup to do so. Wheres the proof that i have it or the proof im doing it? Just because you heard it?

Ive heard all kinds of things about you. Does this make it fact?

Hell, in the last thread, i was accused to be a Diablo dealer

You guys are grasping for straws.

 

Let me educate the ones calling the kettle black here.

During system operation, many functions are performed at the same time. First the PCM supplies many input sensors with a power source and ground.

This power source is commonly referred to as voltage reference, while the ground path is commonly referred to as signal return. The internal components of the PCM that supplies this power and ground is known as the "REFERENCE VOLTAGE REGULATOR."

Most of the input sensors which monitor engine conditions require a regulated power and ground circuit in order to function correctly.

Without the STABLE reference points provided by the voltage regulator these input signals would present inaccurate information to the PCM. The PCM bases many functions on this reference point.

The reference voltage provided by the PCM is approximately 5 volts. A sensor will receive this reference voltage and depending on the state of resistance within the sensor itself, return a voltage signal to the PCM.

The voltage signal received by the PCM will then be compared to the 5 volt reference and a decision will be made determining the state of a particular engine operation, i.e., engine tempature or throttle position.

Sensor information is relayed in the form of electrical signals to the PCM. These signals maybe low-voltage, High-voltage, or varying voltage frequency. The microprocessor in the PCM can only interpet signals that are digital and have a given voltage.

This type of digital signal is manifested as either high or low voltage or as an on off signal. Whether these signals are received as high/low voltage or a on off signal, they must be tailored into a usable form for the PCM.

This tailoring is referred to as signal conditioningand is performed by the PCM's inputconditioners. (Analog to digital converter) in the PCM. Example being, the oxygen 02 sensor sends a low voltage signal to the PCM. The signal conditioner within the PCM must first amplify and translate this signal into a form that the microprocessor will understand.

Which means the signal received by the microprocessor indicates the oxygen content within the exhaust. There are two types of conditioners in the PCM. An amplifier for amplifying weak signals and an analog to digital converter for converting an analog signal into a digital signal.

When the signals have been conditioned into the proper format by the signal conditioners they are passed on to the microprocessor to be used as DECISION MAKING DATA!!

This processing relays the signal information to the PCM's action center, the microprocessor. All the logic decisions that operate the vehicle are made in the microprocessor. The microprocessor is the THINKING or CALCUALTING part of the PCM. I'm not saying the PCM has A.I.

It uses the inputs to make the necessary computations to adjust the output signals or actions of the computer. The microprocessor constantly samples inputs and compares these with stored information to calculate which output is necessary to use.

After the microprocessor has analyzed input information it then decides a course of action for the outputs. At the output stage, the microprocessor controls the output circuitry contained inside the PCM. Output control is defined as simply turning exterior curcuits on and off.

This on/off cycle is determined by the operating rules PROGRAMED into the microprocessor. Ouput drivers are actually just electronic switches. Their function is to open or close the ground circuits of a relay or solinoid which energizes or de-energizes a coil.

This in turn operates an external electric,vacuum, air or fuel flow control devices.

Now, be it Sal or any other person. Again, give me a reason why a calibrator who has this information can't create a program and reflash it into the PCM to out function a chip!! The processor has the ability to decide what table to look and use.

Sal, I know some of the same people Factory tech knows here at Livonia trans. Why Ford trans calibrators would consult you is beyond me. I have to work with a few and have never heard any asking for outside help on their trans calibration. Ok! We can leave it there!

I also know that Ford does not train Dealer people to be calibrators. You learn the replacemant and repair proceedure. The only way you can get in Calibration is to get hired in by Roush or Ford in their powertrain divisions. That's the only way you can get into the cal guids.

Look I'm not here o start a war. I respect the tuners here. However, I won't stand by and let a new process that people can bennefit from get bad reviews before it's out the door. Just b/c some here I thimk do have something to lose.

Kind of reminds me of what happened to Tucker when the big three slammed him. He had inovative ideas and ahead of his time. The other ESTABLISHED automakers took him down before his more advanced car could go into production.

Same thing that's happening here. By the way! If the tuners are not up on re-flashing they better get moving. There isn't going to be an access port in the very near future.

Especially on the new 04 F150. Chips may be around for the old vehicles, that will be it. Way of the casset and 8 track!!

I'm still waiting for someone who really knows their chit to dispute what I have down. If you know that PCM better. Let's hear it. I'm open for debate. The people here can only be more educated and get the facts. Then let them decide what they think is best for their truck.

 

FWIW, the only person that has come across to me as having a finanical interest in this is Mr Jim.
He jumps at anyone questioning the reflash. Hell, if this proves to be what all the posts claim, I'll jump in line
