I've seen this term used several times on these boards, but I don't know what it is. Can ya help a fella out?

 

From what I gather, it's the name given by Ford to the Mustang's computer / prossesor.

 

I've read the guys here talking about it as being the type of chip our Mustang GT's have and apparently it adapts to our driving habits causing the power to drop over time......something like that.




I'm not sure if a v6 would have a "Spanish Oak" or not.

 

It is the new ECC (engine control computer) unit used in 2005 and up. If differs from the old ECC in quite a few ways including the adaptive learning ability. Here is a pretty good article on it. Here

 

that was a great article. thansk for the link. does mustang monthly do a lot of coverage on the new mustangs? one of the subscriptions i dont have yet....

 

the 'spanish oak' part of it is actually the name of the Motorola CPU used in it. I talked to a guy thats a designer for these things, he was going to try and get me some info on them. Ive still got a dumb idea to put a little Aromat(now Panasonic) FP-sigma plc/touchpanel in the car to replace the PCM altogether, think it would be a fun project and too cool to change tunes/revlimiters/etc right at the dash, or select thru the 255 screens available which sensor bargraphs to display, etc...we built a wheel balancing machine a couple years ago using this hardware and its really a cheep powerhouse...CPU was like $350, small GT01 touchscreen about 150, analog cards about 150...blazing fast scan times, and its no bigger than a cigarrette pack...IIRC we ran 750 rpm w/10k encoder and it repeated within 1 count per rev...awesome little unit.

 

well if you flash teh computer does the power fading ability of the ECC fade?

 

^

Thats a good question.


I'd like to hear that too.

 

yes, you have to keep flashing your car, unless someone figures out a way to disable the adaptive learning feature.

 

The only way to do that is to disable the OBDII parameters. Basically, this shuts down your 02 sensors and the A/F curves use the preprogrammed tables in the tune.
