The ECU 'learning' ones driving style is pure myth. The ECU is striving to maintain the most efficient air/fuel ratio of 14.7 to 1 under most driving conditions, regardless of driving style from one driver to the next. By using O2 sensor(s) to analyze the engine exhaust, the ECU determines rich/lean conditions hundreds if not thousands of times a second to maintain a 14.7/1 A/F ratio. When the ECU is using the info from the O2 sensor(s), the system is said to be in closed loop. The system is in open loop when the ECU is controlling the engine using programmed maps. Under hard acceleration/heavy loads/cold starts, etc., the system is operating in open loop using the programmed maps vs O2 sensors.

What do they learn?????? That's like saying they can think. If they could think, it would self correct the so-called oil consumption issue. It's all programming parameters and feedback from sensors that the ECU analyzes in order to achieve a 14.7/1 A/F ratio, or close to it, under most driving conditions.

It all depends on what you define as learning. If the ECM takes the new values that it has obtained over a period of time and applies them to better manage the fuel system then it has learn something. It is kind of like us working on cars, we make repairs one way the first time, then the second time around we do it differently and save time. In other words, we have learn something in order for us to shorten the time. Same for the ECM when it utilize the new information that it had obtained to better manage the fuel system then it is learning.

In some sense, the new ECMs are capable of learning, but not to the point of thinking and making intellectual changes for and by themselves. At least not yet, but maybe it is just around the corner.

So, what and how do you define learning?

N.E.O.

What new values are you referring to?
When "we" make repairs "we", as humans, can think and reason.
Again, what new information does the ECM manage that you refer to?
I don't think the ECU is learning anything, just analyzing A/F ratios and trying to maintain a 14.7/1 ratio.
What specifically do you think the ECU is learning?

Will the ECU create new programming on it's own???

 

[djb383]

I still just don't understand how car ECU can distinguish between 2 different drivers/driving style when the ECU has been programmed/engineered to achieve/maintain a 14.7/1 A/F ratio based on feedback from sensors, under most driving conditions, regardless of driving styles. I guess I'm just retarded.:naughty:

.......there are vehicles out there that can distinguish drivers by means of the key fobs. When the drivers walk up to the car, the key fob signal will notify the vehicle's system to adjust seat position, steering wheel position, A/C system setting, and radio station preference all without any further interaction by the driver when he or she enters the vehicle.........

The ECU is only remembering how it was programmed by/for person/driver #1 and by/for person/driver #2. If it's never programed it will never know, or distinguish between, person/driver #1 or person/driver #2, regardless of time, nor will it learn #1 and/or #2 over time.:thumbsup:

 

[djb383]

.......but just following programmed instructions is not the computer learning.:headbang:

 

[djb383]

Any technical info/proof out there to support this???? Something more substantial than "the dealer service department tech said blah, blah, blah"??? As I've said before, it's been my understanding that under hard acceleration, the system switches from closed loop (O2 sensing) to open loop with set programmed parameters.

 

[djb383]

So your definition of computer learning is .........?

You are right about under hard acceleration the fuel control may go into open loop; however, do you drive like that all the time?

What do you consider technical info/proof?

N.E.O.

I thought I was the one that "doesn't believe the ECU learns" so again, I don't have a definition of ECU learning, just following programming and analyzing info from sensors.

No I don't drive like that all of the time.....neither do others.

Some technical articles/papers etc., discussing the ability, or lack of it, of an ECU to learn.
