Buzzys Truck Problems

[scubapro]

NTBB Thats funny a computer reset after I got mine back last friday with a supposedly new computer & so far everything seems to be running OK. Maybe Mit Tech are now talking to dealers

[borngeek]

or theres a new ECU revision designed specifically to tackle the problem??

[greeny03]

So all good then Buzzy!!???

[daryn]

Na, he is stuck at Frying Pan Creek

Na, he is stuck at Frying Pan Creek

So what's the go has Buzzy burnt it and walking home

[Buzzy]

Haha forgot to post last night.
Made it back all good, done 275k's. No problems at all running like a dream.
I will throw a few pics together of the drive in another thread. Give me halfa

[Cowboy Dave]

good news for a change Buzzy. Did you blindfold the truck so it didn't know you were heading home?

[Buzzy]

I was a bit worried when we headed off after lunch CD. All good though.

[daryn]

Does chaser not want to talk to us anymore to fill us in ?

Good news Buzzy

[chaser]

its fixed so im happy. some how it lernt more fuel pressure and we cant work out how it did. the only thing of i can think off it was a tdc chip or something similler??

[Cowboy Dave]

sometimes when it comes to computer stuff weird shit just happens. I'm sure some of you engineer types would like to disagree but every now and then something random happens and you just can't quite trace it and because of that you can never quite be sure how you fixed it when it goes away. I mean you know what you did, but not exactly why that made the problem disappear. given all the talk of ECU re-flashing etc I can't help but wonder if we're in that sort of territory here

[Homer]

How did you figure it out and what did you do/change to fix it Chaser?

[chaser]

reading fuel pressure reading and followed mitsu procedures. sorry i cant tell you any more company laws.

[Homer]

OK, I understand....so did anyone here figure it out?

[borngeek]

mmm dissapointed chaser....

if only we could decipher whether patto et al can be helped with what was learnt???
i understand corporate governance but at the same time hope its shared internally at the very minimum.....

[borngeek]

OK, I understand....so did anyone here figure it out?

i consider that they have expanded variables in ECU parameters (and hence a further ECU revision - yet to be released) but i may be talking out of school, its just a theory....

[chaser]

yeh its sent out to other dealers as needed...

[Blue]

mmm dissapointed chaser....

As an et al, my fuel pressure has been mapped and is within normal tolerances...

Is that how you got the handle?

Didn't understand a word after expanded testicles

[Wallace]

Good to see that the problem has been resolved..........maybe Chaser could explain the fix to you and you might be so kind as to relay this to the members of this site, therefore "sorry I can't tell you anymore company laws" gets thrown in the shit tin.

[jop]

mmm dissapointed chaser....

.....

Considering it's instant dismissal in most companies to share their information - especially on a public forum, i think chaser has done very well staying level headed through this.

Well done mate.

It is well known we have other mitsu employees on here - so the above comment is very uninformed

[Buzzy]

As far as I know Wallace all they did was reset the factory computer back to standard settings as the computer had high fuel pressure readings. They took it for a drive, went OK brought it back and checked the fuel pressures again, all good and that was it.
I would imagine that this would be a pretty standard practice so I dont know if it will fix other people's problems or not Seems to simple

And no chaser you can rule out a chip, it has not got one.

sorry homer... (sometimes i should re-read...)

well as the chipIT guys will tell you (if they are interested in participating in a thread like this?).
many of the voltages reported to the ECU can tell (a engineer) what is SUPPOSEDLY happening...
problem is it is 1 sensor located in one part of a 'happening thing' (the engine in this case) doesnt necessarily mean that some techie at the programming end understands what is causing that 'increased voltage' so instead of 'keepin on' the engine is sent into 'safe mode/blue screen'... (we all call this limp mode or better still HILUX mode )

Truth is mitsu are NEW to the diesel game (so are many MFG's).. Mits have gone BALLs out and given their rig a bullsh!t crazy extended warrantee period and they DONT want it to cost them the earth...
If they can pull off the odd intake manifold, recon it secretly, and send it back into the wild they will do it all day long cause that stuff is cheap...

this msg is sounding condescending... its not my intention HONESTLY!!!

its just my 10c (ok maybe 99c)

i think mits are LEARNING... they COULD ask warriors of the sport (like peugeot, isuzu, truck manufacturers and the millions of marine MFG's already going) but thats not in their (or the other MFG's) bizo plan...

i think mits tech are being conservative simply to keep their engines SAFE..
I feel they rather learn whats happening over the long term (and make their customers drive their cars in at their own expense) so that they can adjust their computers and future 'learning' of their technology...

i got my handle thru doing this kinda stuff for very large IT companies.... I am far more jaded now

as i said its just my opinion but would not be suprised of a very very close revision/hotfix for our ECU's...

chaser: i STILL really respect your interest/participation in our forum! i only wish you had the ability to SPILL......

You are right it does seem simple but the above comment I find a little hard to relate to as any of the plug and play modules operate down stream of the ecu and control fuel pressure independantly. But at the end of the day the beast is back to normal and that's what ultimately counts. Happy motoring

[Naff]

Yeeaaah nah I wouldn't buy the chip thing either - ECU interprets signals sent to it by sensors and/or a chip , it wouldn't store it in memory like that, it gets overwritten constantly. There's a bug in the original code that sent it into loopy mode.

What if the latest software download got corrupt mid-process and it took some time for it to get into that particular situation where it would cause a problem? It wrote a 0 instead of a 1 in a 128 bit string variable

We could all be waiting for that same line of code to appear and cause problems..
