As for the OP, you're right, a new PCM does have to calibrate/learn. That's the most basic thing there is about how EFI works. Fuel Trim values are set for multiple rpm/load values.
As for adjusting the TPS - that is a RICER MYTH from way back. From a Controls point of view, doing a self-calibrate on the TPS on startup is super super basic. Even Kids in grade school that do Controls know that. Sigh!
If you don't get a "TPS out of range error", then the TPS is fine,
do not f**** with it it or even touch it! Don't even look at it. Don't dream about it at night. Forget that it even exists.
There are many things to do to improve throttle response. But, in real life, they all effect HP. Sorry, I don't give ricer info - do "xyz" and get 3,000MPG, a zillion HP, and handle pulling 30Gs!
The 100% stock air intake, MAF, and TB are all fine for up to ~300HP. They also have very good throttle response.
Heads and intake also effect throttle response.
Good Luck!
The car does not have to learn the new ECU because the ECU is what controls the engine and everything else. So there is nothing for the car to learn, the engine will do what the ECU commands. Do a voltage check/adjustment on the TPS and check your timing. And flash the ECU for codes while you're at it. If the ECU is the same (strategy, BIN, etc...) as the original, then the car should be running better (if anything) provided the original was faulty and the new one is clean, operating properly, and connected properly...
Hmm, how to be nice about this? You really need to learn about EFI.
As for adjusting the TPS - WTF?? The Ford manual clear states that it's a
NON-adjustable part. So, how the **** do you "adjust a
non-adjustable part"? Since the
MID-90's the code has been available on the net, and
anyone can buy/build the cheap hardware that allows them to read the EEC code. Sorry,
there are no hidden secrets at all in the Fox/sn95 5.0 code. Also, "Ford" has been amazing in "allowing release" of how their PCM strategies work. It's super mega trivial for Ford to find out, and to sue and shut down sites that have the document, or even a link to it.
Please, whoever told you that, tell them to take a intake and shove it far up their *ss.
Hey, how the ***** would YOU like it of people went around spreading massive foolish BS about what YOU did/learned/taught!
