Why can't you ROM tune a focus ecu?

I have been looking at everything for tuning when it comes to ford focuses and am beginning to wonder why we cannot tune the way that for example honda ecus can be tuned, even obd2 ecus?

I am not familiar with ford ecus at all and just wanted to see why and if there would be a way to ROM tuned instead of using the obd port?

It seems there is a lot more options in the tuning when going to something similar to a stand alone ecu such as aem, motec, ProEFI and the like, but what about cracking the ford ecu? since ROM tuning "seems" more thorough

not sure just looking for insight

Thanks

not my work. i found this on google.


ROM is an acronym for Read Only Memory, a type of unchangeable memory residing in chips on your motherboard. ROM contains the bare minimum of instructions needed to start your computer. Because it's used for critical functions, it can't be removed short of ripping it out of the motherboard; adding to it is just as difficult. Think of it as analogous to municipal utilities, such as gas and electricity. If you want a different configuration, you'll have to "move on" to a different motherboard or computer. Incidentally, the term "ROM" is also used, not entirely correctly, when referring to some kinds of storage media that can't be modified, such as CD-ROMs.

I believe your looking for EPROM (Erasable Programmable Read Only Memory)

EPROM as mentioned may be closer to what you mean, can't see the "improvement" in having to program/swap chips over being able to plug in and make major or minor changes right through the OBD port, and all tuning that's useful being possible this way seems like a good thing, as opposed to needing a different ECU that may not be an improvement overall...

My understanding is that the standard ECU is more powerful and flexable a unit than any standalone system. We just don't benefit from other methods.

I think flashing through the OBD is far more convienient than changing chips, or pulling the whole unit. By brother has multiple ECUs for his Turbo Del Sol that he swaps, for instance.

What he is talking about is LIVE tuning where you can change things on the fly with car running
I worked with Sniper and they had a test product that I tried years ago that somewhat worked but that was many years ago and they never went further with any of it

I also would like to know why no one has come up with LIVE tuning

Live... AKA. Real-time flash. It http://www.sctflash.com/
It allows real time Diog and Flash. GET IT. The problem with ECU tuning described above is that you DO INDEED have to pull the ECU or you have to run it to actually know what the postition of everything is. With real-time youll know (compared to previous stats) what you're running.

wow, 6 posts and you think you know what your talking about? although no one understands the gibberish you posted?
By the way, you do realize 1turbo is an sct dealer and tuner.

with the sniper system you didn't need to remove. plug and play. to bad they never went further with it.

First off this is a GROUP. A small car shop located in Iowa, Midstate Machine
We've been tuning cars since before you were born and have a magazine features to prove. You even mentioning that "wow 6 posts and you...) made us laugh. All that you are doing is showing that probably most of your 'expertise' is located in books and online forums. While you've been posting your... whatever almighty post number... we were in the shop actually doing it. With that bein said, im not sure what your gettin at saying he is an sct dealer and tuner. So? he asked a question, our input was given. Simple. The whole point of a Forum.
The gibberish that you read, real shop talk. Maybe bring a car by and you'll understand how 'gibberish' drives
