Does a Disco learn your driving style or is this an urban legend? I want to say that I've read this before. I just recall reading that the trucks computer learns your style and must recalibrate if driving habits change. Anyone shed light on this? I know it sounds silly.
Thanks

I was told that at LR school, but it was on a Freelander... supposedly it's mainly the transmission that "learns".

When I first got my truck (in Feb) the "check engine" light came on about a week later. I took the truck in and the Service Manager told me they had to change the warm-up cycle because the previous owner liked to warm-up the truck longer than I did so they had to adjust it to my driving style. I don't know if he was blowing smoke up my butt but that was his explanation for why the check engine light came on.

I certainly believe they have a mind of their own!

Your Disco may need counseling if you do not treat it correctly. Some have been known to throw tantrums.

All EFI systems "learn" a few things about the input sensors after the ECU is connected to the system. Nothing to be concerned about unless you are replacing sensors or chips. Learning period would be measured in minutes, not years.

My Discovery doesn't seem to learn anything, and I have to say my driving style is rather volatile subject to change at any given moment without prior notice. However, when I had my Freelander, it really did adapt to my driving style like it was almost able to sense what kind of mood I was in half the time. If I started driving in a passive way, the transmission even sometimes skipped 1st gear and went straight into second gear off the line as well. If I started driving aggresively, the transmission started downshifting much more readily and holding the higher rpms longer before upshifting and so on. My Disco so far has not exhibited any of those behaviors.

Due to the nature and complexities of an engine, it would not be practical(or legal) to "adapt" it to the driver.

Now that you mention it, the transmission could easily be a way to alter performance based on the drivers desires. That's why some people want a manual trans. The gear you're in has a major impact on the way the vehicle performs.

It would be relativly easy to program a computer that selected and shifts gears based on the driver's input via engine sensors.

I think my D1 was trying to tell me it didn't want to leave vacation in the Outerbanks a month ago, I don't want to spend thousands in counseling but I really need to know what my Rover is trying to tell me.

One of the problems I think is from living in rural central PA, you don't see too many other Rovers and mine may be lonely. I mean it made to 530 mile trip to N.C. with ease, it spent time with a D2 on the ferry to Ocracoke. The whole week it was brilliant on the beaches spending time with a Range Rover Country and an almost identical same color D2. But the last 2 days on vacation I think it knew it was going home again. It started by blowing a headlamp and tailamp bulb then it almost got stuck on the beach. The last day on the beach it almost overheated and didn't want to go out of 4 wheel drive. Then on the drive home only 45 miles into the trip it decided to blow out the bearings in the front differential stopping it permanently. I guess it did spend 2 more days stuck in Nags Head.

After getting her home and doing all the repairs including a fan clutch, it's working great. I'm wondering if I should take it down there more often or if I should pamper it more here by adding more aftermarket off road parts?

Please help my Rover!

Some (almost all new) cars have closed loop and open loop engine management systems.

Closed loop means that the computer is constantly adjusting engine parameters based on readings from sensors. These can adjust A/F ratios as well as other things and hense are "adaptive" based upon operating conditions (load, air temp, water temp, EGT, O2, etc). Almost all closed loop system vehicles run in an open loop (or partial open loop) at WOT.

Most, if not all new, car engines/computers such as new mazdas (like M2 miatas) for example do base programming after the computer is reset (ie. pulling the battery). Depending on how the driver operates the car during that "programming stage" the computer will use those base parameters. As Randall mentions this stage lasts only a few minutes.

This isn't to be confused with adaptive engine control management though. Designers put these features in computers not to adapt to drivers but to allow for variation in each individual vehicle, engine, and sensors (and variations due to age, mileage, and wear).

Now to answer the initial question. Will a Disco reprogram any parameters after a reset? Dunno.

My discovery is a dumb ass. Wont listen to a word I say, no matter how loud I scream.

The way it was explained to me is that the computer keeps track of your driving style, and calculated the best time to run a diagnostic check. During that check, the engine isn't as responsive, so it chooses times then there is no load, like during a long warm-up, or if you like to coast (if you have a 5-speed) in neutral.
Someone new to the vehicle might not do the same things, so it would have to re-learn when to run the diagnostics.

Makes sense to me. Don't know if it is true, though.

DIIs have some adaption in the trans, but it is mainly to compensate for wear, as to a DI . . . effectively none.

As far a s I know, on the DII's, if you put your transmission in the "Sport" mode, it will gradually adapt and alter the shift points according to your driving style.

the only "intelligent" car we have is a 03 xc70. The dealer just reprogrammed the engine and transmission to improve responsiveness.....maybe they can learn...but they need to be taught first
