Hi, I've just registered here so hello to everybody - looks like a great forum. Btw I have a '95 SE V6 Auto.

Anyway during the Magnas last service I had the 'steering lock and ignition switch assembly' replaced to address the car not starting in hot weather. But before this was replaced the problem was incorrectly traced to the ECU and it was taken out for repairs.

Leaving the mechanic the car stalled a couple of times and ran poorly at idle for a period of about 15-20 mins afterwards (gradually got better and is perfectly fine now). Is it correct that the computer needs to 're-learn' after its been taken out and reprogrammed? I dont have any issues with the mechanic simply curious to know if this is why it ran the way it did when I first got the car back.

thanks.

Hey - welcome to the forums, and yes that is exactly what happened with your car.

It needs to re-learn your driving patterns / habits to run properly and yeah - like you said it should be all good now and it is!!

Manual

Great, thanks.

I dunno Manual they never designed it with crazy people like you in mind , how does it cope with your driving style :D

ha ha :lol:

Had the person taking it out followed instructions this would not have happened. You should idle your car for 20 - 30 minutes so the computer can learn the basic idle sequence.

I just reset my ecu and went straight for a drive!!!!!! is that a bad thing!!

it changed gears like a lemon but i thought it was all part of the learning process DAMN BOOK/manual got lost

It's not CRITICALLY bad..but you really shouldn't do that.

You need to let the car idle for at least 15 minutes (better to let it idle for 20) so it can recalibrate the idle mixtures and whatever else it has to do.

So how long does the 'learning' process go for?

Or is it something that is always happening when you drive the car?

Only asking because when I got the car back I wasn't as gentle with it as normal (not thrashing or anything, just a little spirited :( ). Hopefully this has not affected to process too much.

BTW it's my guess that the guys installing the ecu did in fact let it idle for a while because when I started it the car idled fine. It only stalled a couple of times and that was coming to a stop. They should have test drivn it really - oh well no harm done.

the learning process is always happening. I think from memory the magna ecu remembers the last 20 signals for a given situation so if you drive hard long enough you will notice higher gear changes etc

if you bash your head real hard on the airbag it will probably go off.

And your point is? or have you tried this

Just trying to add good information into the thread :lol: :D sorry

hahah i just worked neer the passanger airbag hoping i wouldnt set it off (not that i can...?) would suck if it decided to pop out!!

and as for the learning process my car is fine.. i disconected the battery since i thought it would be a good idea!!!
and thrashed it hoping the car would decide to go fast ;)

widow it wont actually go off.(yeah i know i got the joke). there are i think three sensors at the front and middle of the car that all have to be activated by a certain level of force allwithin about 1/2 a second to set it off. so the stupid part in the movie where the person has a small crash then is ok and gets hit with the airbag 5 seconds later is crap.

I have to disagree with this comment. The ECU does not need to "learn the basic idle sequence" as it already has the base idle and auto choke programmed onto the EPROM. What the ECU does need is to be taken out and driven (not hammered) under normal driving conditions to re-learn. As always I stand to be corrected however I have had first hand experience with a dody magna ECU and a dodgy Galant ECU and have done a heap of research on the matter.

In my experience you have to let the car idle for about 15-20 minutes to let it recalculate the mixtures etc. Because the car will run like a POS if you dont..and it'll take ages for it to get it right.

And the initial post is evidence to this fact. Also when my car was repaired ages ago..they didnt do that either and it ran like a POS then too. Now whenever work is done (servicing etc) I stress to them that it has to be done, and I tell them that I'll know if they didnt coz the car will be a dog.

Hi Mitsu Matt. You are right, there are as you said "base idle" settings etc or it ould simply not run however most manuals will tell you to run these cars and many others for various times to properly learn the patters and all cars are different. You could get 2 cars of the production line in a row and they will be totally different cars.
