Thank you all for the help , i was wondering how is the fueling ? does it need "remapping" or reflashing ?
I am referring to the 04 model .
Part of the beauty of the 15M injection found on the 04 is that it's completely, stupidly, simple. It's open loop -- no exhaust sensor. It's fly-by-cable, not fly-by-wire, and it has only a cam sensor and a couple of temp sensors. It's small and compact in all respects. I fully intend to prove its loveliness by injecting an Eldorado.
That said, there is no 'reflash' or 'remapping' being done with these the way we see it happening on newer injection systems. For one it doesn't seem to be as tantrum-prone as its younger siblings, and for another, we can't upload/download to it like the newer stuff.
That's not to say it can't be tweaked. There are softwares out there (I still use the apostate VSDT software and cable) that will show you the state of your components and allow you to make some trim tweaks.
There are also 'black box' solutions that wedge in between the ECU and the rest of the system, providing a means for the lazy and ignorant to pile on layers of technology in an effort to mask runability issues rather than finding and solving them. I have a few of these that I've removed from purchases -- purchases made for salvage prices because "Even after adding all this gee-wiz stuff and removing all the evil EPA crap it still runs like sh*t." They're like turning up the radio to fix the expensive noise under the hood, or painting over rust scale to give the appearance of pretty. I have never experienced a properly sorted 15M system that NEEDED add-on map modifiers.
