I mentioned in a prior post, after getting my car back from service, it was driving much quicker and smoother. I had asked the person who worked on it, what he did. He stated he reset the computer and then drove the heck out of the car as our ECU are learning and adapt to the drivers style.

Well, 2 weeks post service, while diagnosing an issue with the stereo system, I shut off the power at the battery to check some fuses. I turned the car back on and drove it as normal. I began to notice that my car was driving poorly, sort of like something was pulling the car back when I had my foot on the accelerator wanting to go forward fast.

On Saturday night, I shut down the battery overnight and took the car out first thing on Sunday AM. I litterally floored it from stop light to stop light looking like a Californian Gas Wasting/Guzzlin fool. Well, that has seemed to paid off as now the car no longer has that sluggish feeling. I am almost certain it is not a psychological thing.

Just a FYI if you feel your car isn't running up to speed.

I think this is a pretty re-occuring theme.. These cars are HIGHLY adaptive, and absolutely will drive differently depending on how they are driven. They are meant to be driven and opened up, and are definately happiest when driven hard.

And honestly, I think these are the most adaptive of any I have driven. Audi's, Mercedes, and BMWs tend to adapt their programming pretty quickly, with smaller overall differences, and less remarkable differences car to car.

Yes! The power is down, the shift rates are sluggish, it just doesn't feel the same...and since they were working on the fuel tank, I suspect that the battery may well have been disconnected...

How long does it take to "adapt"?

Is there any one from Maserati technical out there? Can we ahve some technical advice.. as this is very interesting.

I am pretty sure that the adaptiveness is quite significant and particularly ont he shifting.. I notice that when driven harder even the normal mode shifting is sped up ..

My Sport shift is very quick no complaints..

but I have noticed that the normal mode shifting is quicker after the clutch was replaced (see vibration thread for reason).

Rick

I have noticed the "learning" and the results occur instantly. I have toyed around with this a couple times, but found it is critical how you drive right after the car is restarted. For example, if it is driven hard in the first few miles, it will likely remain that way even if you drive it normally in mile 3-10.....however if you drive it like an old lady in miles 1-3, and then drive like Schumacher in 4-10, mile 11 will drive more like the old lady.

I noticed not only quicker shifting, but faster acceleration between shifts. When I had shut down the power working on my stereo, the drives after that were sort of like I was driving on uneven pavement....after i reset the computer, it felt like I was on ice or a smoother surface as the car just proceeded forward w/o any resistance.

As they say YMMV, but I am convinced my car is performing signicantly better. the first time this was done, I actually went back to the mechanics shop 5 days after getting the car back asking him "what the hell did you do to my car?" (with a smile on my face)

I think i am having the issue described here...

When i took the car out this morning, the car was very sluggish. There was a clunking noise and when i stepped on the gas the car wouldn't move. This lasted for a couple of miles. After i picked up speed, i think it was fine. But i still feel that in lower gears, it didn't have the power it used to.


Reading this thread, looks like a resetting the battery would fix it. Am i correct? Suggestions/Advice?

OK, so how long does the battery need to be disconnected for the computer to reset? And more important, how can you do it without then having to reset the time, stereo presets, and equalizer every time?

Got the car back from routine service two days ago and was told they did a software update. Car was sluggish and wasn't quite as "tuned-in" as i recall before sending it in. Redlined it a couple of times yesterday and its almost back to normal. Strange. :confused:

Nothing like joining a thread 2 years late!

The reset they are doing is of the transmission algorythyms. I know on the ZF Automatica's on most cars, you can do this yourself. There are various iterations but to be safe try this:

1- turn key to ON position (last one before cranking engine)
2- depress gas pedal all the way to floor, HOLD for 10 seconds( some say 5, others 25)
3- continue to depress gas pedal and turn car off and remove key
4- release pedal.
5- some say wait 2 minutes after restarting, others say go, go, go!

For me, I hold down 20 seconds, and just drive. Most of time there us a noticeably stronger, smoother engine!

Try it and let us know. Try again if fails the first time.

Does this apply only to the trans programming or the engine programming - just wondering if this applies to Coupe GTs?

Wassy - I'm guessing you still have the battery switched on during this routine for it to have any effect, but I've got to ask - on or off?

on. it's quite simple actually. this isn't about resetting seat, or ECU (except for tranny). It's the procedure for most ZF's, and from what I've read, many others as well. Look at BMW boards and you will see ton's of posts..

Wassy, about how long does it take for the Cambio-tranny to "learn" your driving style? If I've put a little over 300 miles on mine since I got it, do you think it's gotten "used to me" by now, or would I be better off trying the procedure you mentioned & just go for a re-boot?

I find myself tending to use it in "Auto" mode in certain (not all) city driving situations, but I don't really like the way it shifts when left to it's own devices... it upshifts a lot earlier than I would, and downshifts a lot slower. In the morning, before sufficient coffee infusion, though, it's definitely convenient lol.

The reset will only do so much. If the car is new, try it and see if you notice a difference. From what I've read, if you want a more aggressive learning pattern drive hard right after reset

Wassy, the car's not new - I'm just wondering if there's some kind of "hangover" from the previous owner, in terms of how he may have driven the vehicle vs. how I tend to drive it. I've only had it a fairly short time & as a result haven't put that many miles on it yet, so perhaps it'll just take it a little while for it to adapt to or "learn" my driving style - was just wondering if a sort of re-boot like what you described might be the best bet.

I'll tell you what, though, I did notice that today when I had it in Auto for awhile, it was shifting from 1st to 2nd more in the 4k-5k range, which is where I tend to shift when I have it in Manual mode, as opposed to the 2.5k range it was shifting into 2nd when I got it... so maybe it's adapting already.

Difficult for me to say, since this is my first experience with these cars.

it won't hurt you to try the reset. Again, sometimes it works, sometimes not. For me, it almost always works. Try different times for holding the pedal down if need be. Do a google search for ZF reset, or transmission reset, etc. You'll see the posts mostly on BMW forums because of their far and wide reaches, but works the same nonetheless.

Let us know if you see a difference. It basically puts the learning curve back at factory state.

This learning procedure should work for the QP and GranTurismo with the ZF Automatic Transmissions. However, not for the Cambiocorsa, DuoSelect or MC Shift transmissions from my experience. It's not going to hurt of course to try it but don't be too upset if you don't see the benefits on the other transmissions that come in the Maserati.

Best Regards,

So how do you reset DuoSelect / Cambio?

I had thought that disconnecting the battery reset the DuoSelect to factory settings. Is that correct and if so, is the factory setting the "fastest" shift possible without DBWE?
