interesting faults found on the 10, even from showroom

[scott_drake]

After my horrible crash and being hospitalized for a week and being denied insurance for multiple things that fall under "CLAUSE BLAH BLAH BLAH" which im still battling in court....


Me and a mechanical engineer teamed with a race mechanic and crash forensic reconstruction specialists, electrical engineer and computer programmer we have been focusing on the s-awc system and rear diff and found there are problems with the following things from factory with these cars: Confirmed things are

1: ATF SPIII Fluid not suitable for oem recommended time drain intervals, the oil looses its properties very quickly and does not work as it should, the oil also lacks a anti corrosion property in it to stop the pump and system from rusting internally or seize up from overheat
2: Rear Diff Pins backing out because of: oem oil time drain intervals the pins back out because from factory mitsubishi did not cast/machine the inside diff housing to have enough oil passages to lubricate the pins while in motion, oem drain intervals not suitable for oem diaqeen oil
3: Wheel speed sensor wiring to main ecu is very close to high temperature items which "could" cause incorrect readings to ecu


4: There is no "FAIL SAFE" for a malfunction with the items relating S-AYC System which controls the ecu, malfunctions include wheel speed sensors failing, steering angles sensor failing, burst tyres, ayc hose blow out, wheel lock up, and better yet BRAKE FADE through corners or electronic glitch in the s-ayc ecu....


In simple English what number 4 means is if: one of those things are to malfunction/fail """while driving""" the s-awc ecu will not recognize a mechanical failure but assume its working fine and the car s-awc ecu will try everything to correct it

if it is a electronic failure the s-awc ECU:

-MAY OR MAY NOT send the spedo display to service required screen (still working on this one)
-the s-awc ecu will try everything to correct the cars dynamics even though they are correct but because the s-awc ecu has not recognized it as a fault it will think its working and the s-awc ecu will correct the car resulting in loss of control


This s-awc ecu is a tricky bastard, my guys are having an electrical engineer with a computer programmer to try and crack the brake down and write up a diagram of this S-AWC ecu and HOW is communicates with the main ECU and what triggers the service required screen and what doesnt....and reprogram it to have a fail safe and test it out again....


other things still to be looked at are drivetrain clearances


My case has really become a tricky and sticky process


ill keep you guys posted as soon as i have more details

so what your saying is if your driving the vehicle to a point where the ayc has be engaged to stabilise the car which is usually over 100km (how they demonstate on tests like top gear etc) and its not working the car will act like a regular non assisted 4wd car.

heres the thing, ayc operates the entire time, you dont need to be doing 100km/h........what im explaining is that if there is a mechanical fault relating AYC operations it will not assume this as a fault but rather a variation in wheel speed so it will send car hay wire.......basic test....jack up your car all 4 off the ground....put it in 2nd gear and drive about 20km/h above, than gently slow down one wheel and try to stop it then watch what happens to the other 3 wheels, you will see what i mean

[R4LLI4RT]

so in any case if at high or low speed the ayc is prone to malfunction (as any electric or mechanic component of any car).
i dont get how it would affect or make a diffrence to some1 who is diving on streets.
the issues mentioned in point 4 are from what i understand are things the evo dont report on like brake fade but i know for a fact if you drive on a flat the ayc throws a fault code because it did it when i drove around for 5 mins on my spare tyre not long ago

no your missing the point, u said it yourself ""car will act like a regular non assisted 4wd car""

that is what SHOULD happen....BUT the s-awc ecu WILL ASSUME there is no malfunction but rather a variation and will technically "over correct"the variation resulting with ecu conflicting with driver inputs,

the steering angle on the 10s play a very intresting part of s-awc and how it controls the 4 wheels...we still digging deep into it

[BST50N]

Interesting - keep us posted. Its kind of worrying how there is no 'failsafe'.

The RA doesn't have this s-awc does it?

[sleeper]

no

[scott_drake]

this is my whole issue of my car accident, a wear and tear part can let go at any given time we all know that shit happens with cars, but the question is WHY hasn't mitshi developed a "fail safe system"in the event of a electro/mechanical failure to basically shut down s-awc ecu and allow the driver inputs to take over?

they are able to have LIMP mode for countless engine faults and emission but how come no drive train failures codes?


Why doesn't the ecu recognize it as a failure rather than a variation and ecu conflicts with driver inputs


anyways....just some intresting info we are digging up, ill keep you posted with more info

[Jason-VR]

Scott are you at fault at all?
Do you want to drag every other car at the lights?
Are you are car enthusiast or hoon?
With maturity you hopefully will change your attitude. Hopefully before that happens you don't kill someone else on the road. Luckily for me you don't live in my state.

No i was not at fault, police and witness even confirm it
No i dont DRAG/RACE on the streets after seeing the after math of a close friend die (he was driving with road rules) he wasnt racing
I am a car enthusiast and a HOON on the TRACK
I abide by the road rules, i drive deferencely, you just need to spend a week on sydney roads to understand what i mean

[BST50N]

I don't think any of us can know what really happened as we weren't there. Cars are machines. Machines are made by people. People stuff up and so do machines.

Scott's case may well have been a electonic/mechanical failure - apparently its even happened to our resident guru Beeble.

Whatever the case, everyone is ok, so that's the main thing.

Scott is doing something good here trying to figure out what issue caused the accident - hopefully others can learn from this somehow, or we can get something out of this accident so that it doesn't happen to anyone else in the future. It might be possible that people could upload a simple fix to their ecu and prevent the car going into 'crazy' mode.

This is how bad some car manufacturers can be and how serious problems can be before they recall.

[scott_drake]

Look i cant give any details about the FACTS of when where and how...becuase im a matter still in court


Lets just say go look at ANCAP crash test of 08 lancer at 64km/h and see the damage for your self and compare....THESE CARS CRUMPLE!!!.....


And secondly i did not get denied insurance because of any driving related matter, it was denied because of PRIOR to the accident and AFTER the accident there are MANY legal loop holes in this that i am batteling in court, and if my investigating is sucsuessfull that mitshi screwed up this will be in the court matter aswell....this process can take me years



this is still VERY VERY early stages

[scott_drake]

Read up on Beebles post about how he got THROWN off the track mid way corner on the evo x forums and what he traced it down to...u will really stop and think after reading what he found about modding these cars and how you should and shouldn't mod and you will start to agree with me that there IS an issue with the S-AWC ECU.....

Now from what i know of beebles scare it was because of a coilover or strut bar or something rubbing with the speed sensor wire not giving it proper contact making it go ape shit........

So IF it was a stock evo 10 and for SOME reason it failed, why doesnt the s-awc ecu realize it as a failure and put it into "SAFE MODE" ie SHUT DOWN S-awc ecu and allow it to be a Neutral awd with no assistance and disply an error on the dash....but instead it assumes its a sudden variation so it goes ape shit.....We are still working on what triggers the screen to pop up and what doesn't and what it reads as failure and what doesn't and how it behaves to:

FAILURE over VARIATION



^^^^^^^^^^^^^^^^^ that is the bastard we are working on




who knows if i proove to be right there will be a world wide recall on every mitsu ever produced that comes with AYC....


We "could" all be driving death traps....if im right then that would be the end of mitshi....even though i love the mitshi performance cars to death, some basic things where really messed up on these cars



Think about every claim/accident/faluire relating to a mitshi that has ayc that caused someone LOSS and even if its a few bucks...mitshi would have to compensate for those losses....and they would be FINED MILLIONS if not BILLIONS of dollars by the governments...


Just my thoughts
