Just had my car serviced last week, it was treated as a 24/36 month service. so the only extra things done from the 24 month service, was break fluid, coolant and one other thing- cant remember. Any way i told the service person that the gear kickdown from fourth to third was very harsh when drivinh at around 80 km. That is when doing about 80 and you plant it, it changes back to third vary abbruptly and you can feel it through the whole car.

So they said they would flush the trans and adjust the trans and i think the throttle to help resole the harsh kick down.

Any way, it doesnt seem to do it as harsh. Havent really had a chance to test it properly, but I seem to be chewing through the juice at the moment, and it almost feels as though the car is holding third longer, so when iam coasting at 60 its consuming more fuel than normal. I dont know if its just me or if its cos of what they adjusted? They said to call back and let them know how its going when i picked the car up, but like i said i havent had the chance to get it onto a godd stretch of road to give it a bit of stick.

Could they have adjusted the shift pattern or something?

I think your ecu has just gotten itself set into aggressive driving mode judging by the fact people's been testing the car in 3rd gear @ 80km/h, so it will tend to hold it's lower gears longer anticipating move revs suddenly coming thru from the engine.

I find I can educate my ecu (after some sprited driving) to change back to a higher gear by forcing via the triptronic after a couple of times, my AWD gets the idea and automatically go into 4th sometimes 5th gear @ 60km/h.

In anycase i think planting it & causing a kicking down into 3rd gear @ 80km/h is very hash driving indeed (or I must be getting old :cry: ) so I think unless it's bothering you, I wouldn't do the transmission oil unless manual says its required.

Also what grade engine oil did they put in? My AWD manual calls for the very light 0W30, with a note that says heavier oils shall cause increased fuel consumption.

Edit: sorry didn't check - you're on full auto - some gentle driving should ease the ecu back to its old self.

Yeah, ive been trying to drive it easy so as to not use too much fuel. I dont really drive my car that much anyway (only weekends and some nights during the week). but when i do, and given the opportunity to open it up i take it :D, just didnt feel right the first time it happened, which was going up a hill, then it happened a few more time on the flats. But ive noticed before the service, inst fuel consumption sitting just on 60 km would be any where between 3-8 L/100Km (roughly), now somewhere between 5-10 L/100Km. Its actually more economical to sit on 65 to 70 km. For obvious reasons, this is not a good thing. Could they have reset the ECU perhaps. And what happens when they do reset it, does it learn the way it is driven and adjust to that?

what fuel are you useing like what fuel compney

normally use shell premium or unleaded (depending on finances), but the tank im on now is BP ultimate, first time ive used this fuel. Could that have something to do with it?

if you want to shift to 4th at 60km/h try dragging 3rd to abt 70km/h or slightly under and then release accelerator gradually to induce upshift to 4th. don't know abt other magnas but 60km/h is just about the changeover from 3rd to 4th on my car.

Yeah, thats sort of what ive been doing, but only up to about 65 ish

Over the last couple of nights, ive been accelerating up to sixty and barely put anything on the accelarator to keep it there, and have noticed it starting to use less fuel, between 5-7 L/100km, and noticed it shifts into 4th just on or just before i hit 60. Iam probly heading up to Gawler on sat so should have a good opportunity to see how the harsh kick back has been adjusted.

I dont know that much about the ECU's in the magna, but do they adjust to the way they are driven IE adjust tothe drivers behavior, if thats so that would make sense cos they may have had to reset the ecu to adjust the harsh kick back from 4th to 3rd at 80km, and the ecu is relearning how i drive, am i on the right path here or am i completeley wrong? :nuts:
Any feed back appreciated.

ya they probably cleared your ECU's memory (eg disconnect battery for 20 mins), now it needs to re-learn your driving style. Just drive "normally" for 2-300kms.

your ecu doesn't learn, the gearbox computer does.

so would they have adjusted the shift pattern via the gearbox computer? this would explain the third to fourth shift in the auto trans being closer to 60 km then before. again appologize for my ignorance on this issue, dont know much about modern cars (cars in general). So they would have had to reset the gearbox comp to re-adjust the shift pattern? The person who spoke to said thay also adjusted the throtle response or something like that, again any ideas? :nuts:

form memory there is an ecu reflash that rectifies 4-3 kickdown. let me check it out when i get back to work and i can give you the reflash number and your local guys can work some magic. as for the economy...unsure but try reset the ecu by taking the battery back off....also make sure if the trip computer has been set up for 3 or 3.5 litre and sedan or wagon.

Yeah I had a rough 4-3 kickdown. They flashed the ECU and it fixed itself.

ECU = Electronic Control Unit, not "Engine". :)

My car was in the shop yesterday for a voluntary auto flush, the bill said they did a "REPROGRAM AUTO ECU" job item too.

can u get yur ecu reflashed for different settings ?

Yeah... but AFAIK it can only be done by Mitusbishi service centre (they've got a special machine) and I've never heard of anyone having any success getting mitsubishi to agree to using it to do any 'cool' stuff like leaning the fuel/air mixture or advancing timing etc.

that is a bummer, what sort of chip is on the ecu? if its a standard eprom or swappable for one, it would be interesting and achievable to mod it with a eprom writer/reader

dam it would be a lot cheaper to get it reflashed then havin to get a chip

well, the latest update on the matter, the last tank of fuel directly after the service, roughly 14L/100Km, but towards the end of the tank, the inst fuel consumption at 60Km progressively dropped the more i drove it. Took it on the open roads on the weekend, with a fresh tank (BP unleaded) and the harsh kickdown definately alot smoother. I tested the kickdown a number of times and its no where near as bad as before. As for the fuel consumption, this tank is on around 10L/100Km. Obviously the open road driving has brought that down but i can feel the car changing into 4th just on or before 60km, which is also reducing the inst fuel consumption to around the 6L/100Km level.

after saying all that, do the gen 3's learn or adapt to the way they are driven ;
1. after ecu/trans comp (or whatever) is reset?
2. all the time?

yes the auto will adapt to your driving style and learn other peoples...it is called invecsII.
it does this all the time but is reset from base settings if battery is disconnected. 58kph is the speed at which 4th gear is able to be engaged under this it will not change up....but if it is changeing early under more heavy throttle then there may be a problem will sensor adjustments or it may just need another relearn.

black beard...mitsu dealers cannot re-map ecus as they please...only set and certain reflash procedures....i wish we could do that. :D

cheers mon

i am pretty sure the invecsII features only on 5-speed autos. the 4-speed autos are just conventional autos. correct me if i am wrong. :cool:

ok you asked me to....you are wrong :P ...invecsII features on 4 speed autos as well.

this has explained alot of things for me, thanks guys. Any more input greatly app :D
