reading the ROM from the ecu is a programmingsession...

 

oh damnn i jus stumbled onto this thread...didnt know theres a "recommended" number of flashes. i constantly flash between my 91 and 94 maps depending on what gas is available for me. x__x

 

I believe I had read somewhere that if you flash too many times the ecu could begin having errors... But seeing these people with hundreds of flashes... Obviously that threshold is very high, if there at all lol.

didnt read the entire thread so i apologize if it was answered but.. is there a way to clear the flashed history on the chip so it looks like it is stock and untouched?

 

not publically available..

its easy enough to reset the counter, but I dont have a baseline for what is factory...

 

ok so the last thing you said.. i basically read that as you cant pull off the data from the source to see what it comes with so its pointless?

sounds like its something like the xbox 360's use for nand chip or way different?

thanks for answering my questions. i owe you another donation soon also.

 

tephra,

is there any way to get the ability to change this? (paid sep app?) If we can see how many its at now we can at least at our choice set it to what we want. (In my case my car has been flashed 4x.) Also I know you don't control evoscan but does that actually clear ALL dtc's from a flash on a MR? Thanks!

 

Isn't it possible that factory could vary though? Perhaps they tune multiple times for QA / testing.

 

The only time I can see this ever being used by mitsu is if they have to send engineers to investigate a big warranty like an engine, tranny, diff etc etc.

So unless you are worried about warranty, continue enjoying your tuned evo Otherwise, you have to pay to play my friends.

 

I actually just got turned away from a warranty claim for a sensor b/c my calibration id was changed.

 

well this isn't your calibration id thats basically just a checksum that mitsu match when you go in for service... if it doesn't match then mitsu assume that you have either flashed it, or done the update yourself, or they did the update but forgot to make note of it

 

i detect a loop hole just mentioned there.. if they forget to make note of it lol.

For sure there is no factory flash counter that communicates with MUT software anyways I think what you got there (and the skill to get to it) is so far beyond anything anyone at Mits could ever get into that it's probably not too much to worry about with warranty stuff. Glad you don't work for them!

 

They should still warranty a tranny even if you're tuned. I left my tune on completely when they warrantied my t-case
