I've heard the 951 has a "learning" ECU that adjusts to the way you drive.

I've been driving like a granny for the past few weeks commuting, but am heading to an Auto-X this weekend. Should I reset the ECU, so it starts fresh and (hopefully) more agressively ?

If so, how do I do it ? I've heard it's something like disconnect the battery, hop up and down on one leg, put the key in, turn it, and sing "I'm a little teapot". But I could be worng on the details.

Thanks,
Mike.

Hmmm..drive super aggressive for the next few days?

To my knowledge there's no solid state memory in the ECU, so it can't remember anything.

The DME's don't remember a thing. They are not that advanced.

Nope, or else my car would not even let me start it, lol.
It's all pre-programmed.
It's around when OBD II came out that they started introducing learning ECU's.

Where did you hear that?

My Mustang had the OBD II which was a learning ECU. The computer adjusts to your style of driving and would have to be reset before each race event. Reno

Yes , they do . When your car suddenly stops while you are driving and can't find an answer why it did, it is common knowledge to pound the hell out of passenger floor board under which resides the computer. If it starts that computer has learned anyway you look at it.

George, is that a case of the computer learning from the driver or the driver learning from the computer?

Yeah, the other guys are correct, there's no memory in the computer that can store anything and none of the data parameters such as fuel & ignition settings are on re-writable chips. The way I see it, things have a combination of two types of states: working/not-working and broken/not-broken. This yields a cartesian product of 4 possible values:

1. working/not-broken
2. working/broken
3. not-working/not-broken
4. not-working/broken

Then all you have to do switch a device between these 4-states is to smack it. Some state-transitions require more force than others. So when in doubt, use more force!!!
