What does this ECU thing do?
Does it actually program itself according to your driving habits when driving a new vehicle?
If so what if you're driving like crap?
Does it get programmed crappily?

Explain driving like "crap". It is the brain of the engine. The transmission has one too. It does everything from ignitoin timing, to automatically locking your doors at 15 mph. It does "learn" the way you drive, like hard accelerations and such, and adjusts settings to give you best power and mpg from the way you drive. If you drive like a 97 year old granny, it knows that too.

Well since I'm either not used to my manual transmission yet or there's something wrong with it, my driving is very bad. I've also been trying out different shifting patterns and getting the rpm's up a little higher than I normally would just to break it in. (I'm only talking between 3000 & 4000 rpm, but I would normally stay below 3000).

I don't want the ECU to learn this? Will it relearn my habits later when I'm driving better?
Or does it set itself and then stay that way?

It's always learning,but since you have a stick it doesn't learn your driving style as a ECU would for a auto.Your ECU controls the ignition,alternator and monitors all the sensors to maintain to best air/fuel ratio for best economy/performance.The BCM(body control module) controls your HVAC,door locks,keyless entry,factory security system,and EVIC.The TCM(transmission control module) controls the auto trannies,manual trans KJ's don't have the same type of TCM as a auto,they do have sensors in the manual trannies that the ECM does monitor though.

It can be reset by disconnecting the batter for 1/2 hour and pulling on the headlights to do away with any stray current. You will have to reset your radio though. He is right about the Body Control Unit. I though it was tied in together but apparently it is seperate. When you test drove the Jeep with the sales guy, was it doing all this jerking around?

That's a good question. I don't remember. If it did I just wrote it off as inexperience with a new vehicle. I bought it after the test drive, so I guess I liked it at that time. I don't remember anything negative from the test drive. I've only had it a couple weeks now---------about 600 miles.

Well you can do like other recommended and try another one, and turn off the ESP and see. If it is you, your left foot needs to be re-sencronized.

DId you check for recalls on the web page? Or find out if you need to be re-flashed?

just curious.

Yes. I checked for recalls this morning. Nothing.

So let's say you start drive one way for a long period, but then you change the way you drive. Maybe you move from the plains to the mountains or you sell your Jeep to your Grandma.
Does the ECU then relearn what it needs to for the new conditions, or is it permanently programmed from the earlier times?

It is not picky. It will re-learn. It may take it 500 miles to do so, but it will happen.

It's constantly adjusting, it's pretty much an average of your driving. Think along the same lines as the computerized MPG average-it may be reading 19mpg, but at the moment you could be getting 12mpg, so after a few instances of this, you may be reading 17.5mpg. Then after 3 hours on the highway at 25mpg, you'll be reading 20mpg...it's a constantly adjusting system, and all it really does is monitor the fuel/air ratio to maintain the best MPG for your driving style. It will eventually balance out no matter who is driving the vehicle- be it 16 year old invincible new driver or your grandmother Sophia wo does 45 on the highway while peeking over the dashboard. The longer one person drives it, the longer it will take to balance out, but it will in time. 600 miles isn't quite there for it to learn your driving habits, but it should be feeling a little better than it was yesterday or the day before. Take a roadtrip somewhere and it should get better quicker. At any rate, give it some time, you'll get hosed on the trade-in no matter if you have 1000 miles on it or 2500 miles on it...

It will do it in 5 or 600 miles.

My JK took about 850 miles to stop feeling dopey off the line and while shifting (manual), I'm just going from my experience. Our '07 KJ didn't stop being annoying (auto) until about 900 miles or so. It wouldn't roll without help from the skinny pedal, and once you pushed on the accelerator, it would hesitate for a second and then take off like a rocket.

THIS IS EXACTLY WHAT I'M EXPERIENCING !!!!
I'll push the pedal down and it wont' go, then all of a sudden it kicks in and the rpm's jump and I jolt and jump and wonder if I'm losing my mind. I knew I wasn't crazy...............................unless you're also crazy.

They should put stuff like this in the manual, so you know it's normal.
So it sounds like mine is not screwed up and it will get better.

I would disconnect the battery overnight and let the ECU reset itself to factory defaults. Since the car is new, the ECU could have some funky settings in there from loading, transport, moving around the lot, idling, etc. Start with a fresh ECU and let it learn your driving and environment from scratch rather than having to retrain itself over time.

If you are still having a problem 200 miles after the ECU reset, you definitely have a problem that the dealer needs to look at.

Yay! I finally communicated something successfully over the internet!!! How did your test drive go BTW?

What did you own before the libby?
I used to own a turbocharged VW which was much lighter, and was probably easier to drive than my 6-spd jeep. Here are a few things I picked up along the way:

1) Slow down your shifting. It's a truck, not a sports car. It's not a race. Let the clutch all the way out before you stand on the gas.
2) If you're having trouble with it trying to grind going into second, hold the shifter where the boot meets the knob (lower), and try and be more gentle. I've noticed it will try and grind second when the transmission is cold, or when it's really cold outside.
3) As I said, it's not a sports car, and the odds are that it has at least 100lb-ft of torque more than your last vehicle (considering that 90% of vehicles out there are 4 cylinders with 100 Lb-ft motors and the libby has over 200 Lb-ft of torque. That said, pull your shifts, use first to get rolling, then shift to second and accelerate to 25 or so, don't expect to shift smoothly from 1-2 at 3,000 rpm because if you were driving a 4-cyl, the engine will be able to slow down fast enough to make a smooth shift, wheras the 6 cylinder has more mass, and a much heavier flywheel and will not be able to slow down to match the transmission speed in the short time it takes you to shift. To add to that point if you were driving much of anything else, the motor was definently much smaller, the biggest four cylinder I know of is 2.4 liters, which is a far cry from our 3.7 Liters, (that's 1.3 liters different, that's the equivalent of a geo metro's motor worth of displacement.... I don't completely know all the math (I always drove smaller cars where you didn't add cubic inches and all that stuff, we just make them flow better or add boost) , but I would assume that would mean that the internals have to add that much more mass for each liter...

Anyways, it took me over a month to begin driving my libby as smooth as my VW or hondas of the past. But once I changed my mondset I find it fun to drive the manual transmission.
Good luck!

I used to own a little GMC Sonoma pickup---4 cylinder, so yes, the Liberty is a big change. Thanks for the tips.
I was just out driving and maybe getting a little better, but I don't know. If I want to take off at a good speed from a complete stop it seems impossible. I'll shift to 1st if on a slight uphill and that gets you about 10 feet, then I'll shift to 2nd as fast as possible which will just jerk and lunge me all over the place. In the meantime cars behind me are pissed and cars in the other lane are just zipping right on by.

I pulled up to a stop light and was beside a Jeep Liberty Auto (I assume). The light turned green and they were half way down the road while I'm sitting back there messing around with 1st and 2nd gear. I really felt like I had the inferior product when that happened. There's no way I could have kept up with them......unless you have a secret method you'd like to share.

Sometimes in my Rubicon if I'm taking off quickly from a light or something, I'll use first to get rolling, then actually skip 2nd and go straight to 3rd. I still think that most of your problem is just that you aren't used to the vehicle yet. You think you have it bad? At least you're going from a truck to a truck! I went from a 9-3 Aero to a Rubicon...let me tell you that the transmission felt funny! And it handles like piss to boot! But that's why I bought it, it's a Jeep . You'll get used to it, just keep experimenting. Go out during the day when there isn't any traffic and just drive and experiment with different shifting methods, skipping gears, etc. You'll catch up to the jeep, just give it some time. Once you do, you'll love it .

Yeah, it definently sounds like you are having the same "problem" I was. WHen it comes down to it, I know that if I "power shift" I can do one of two things:
1) Mash on the gas, quickly shift to second, and chirp the tires, and get ahead of the person I wanted to.
2) Spin the tires right off the line in first and realise I should have just been gentle to begin with after the ESP (Electronic Slip Prevention) turns on and stopps my party.

As far as the people behind me, I hate to say it, but what are they going to do? Get out and yell? Semi trucks "pull" the first shift early too, and those people have patience for them.... Just because you don't need to stand on the accelerator at every green light doesn't mean that you don't have a nice jeep, if we wanted to, we could definently pull away "with" the traffic, or ahead of it if we wanted to, but IMHOP the libby drives smoother if you're gentle with her.

Having said that, I have been shifting a little smoother in the 1-2 shift if I hold the shifter a little firther down (where the boot meets the knob), and I have definently begun to accelerate much faster.... one other comment (try and experiment with this one) is that I find that I can let the clutch out a lot faster after I am moving that with a smaller engine car.... I think that it has to do with there being more rotating inertia.

I hope that this is helping a little, I've only had my libby since december 20th, and I was away for 2 weeks, so I'm still relatively new at drivng the torque.
