I thought if you had the 0300 missfire flash from the dealership and you later got it reflashed from a tuner that it would cause the engine to flood or something similar?

 

did you get it fixed yet?

 

Im curious why you wouldn't say which vendor it is... I would think that would be extrememly a good point to make. If it turns out it is the Vendors problem then people should know about it. Thats my thought at least.

 

thats what I was thinking too...also since I know this happened to a friends car, we can see if this is a recurring problem w/ said vendor.

 

Did you check all the fuses?

 

TurboTrix was the ones who originally flashed it. I sent it back and they reflashed it for me for free and paid shipping. However the problem was still not fixed. They weren't sure what the problem was so I called Al, and he said he could fix it. ECU's should be on his doorstep Fri, so we'll c if it works or not. I'll let you know.

 

I could be something else, but if the cars runs "for a second or two", that hardly qualilfies as the engine running... Unless I'm not understanding something, a second or two would only result in the car turning maybe 10 to 30 revs..... Seems like when my car jumped cam timing, the engine would almost start then it got progressively worse. It's still worth looking into I think......
Oh yeah, if the tuner flashed the ECU back to stock, it should start just fine since there would be no change.... Another thing, the inmobilizer does not prevent the engine from starting, but it causes it to die after it runs a few seconds. I found this out when I had a key cut to duplicate my key except this duplicate key was made from a simple blank. I could start the car just fine but it would not stay running for very long. That does not sound like the problems he describes.......

 

my buddies black car would not start at all with a key cut....thats the way immobilizer's work.

 

Having the car run for a few seconds and then die is common among mis-programmed EVOs.

It sounds like it has the wrong software. We make sure to stay on top of the Mitsubishi updates and go out of our way to keep our software library completely comprehensive.

Before we program any ECU, we verify the existing software before proceeding with the programming.

We also have the ability to re-synch the immobilizer with any ECU in-house.

 

Mark said that it acts like it has an 04/05 program on it, but he is for sure positive it has an 03 flash on it. I'm really not sure what it is...but I'd really like to know. I know its in the software, and I know that the ecu thinks the car is turning some ungodly RPM and pulsing the injectors as such...however I'd like to know what it is in the program that causes it.

 

I agree with this 100% and it is the same policy which I follow

It is important that the tuner check the ecu sum code prior to flashing the ecu

Only if a match can be found with the tuners library of base maps should flashing be commenced

The ecu will not start and the car will exhibit the flooding condition if the ecu data that is installed does not EXACTLY match the version which the ecu has

This is a saftey measure built into the ecus by Mitsubishi to assure that all ecus recieve the correct base flashes to assure compliance with emssions laws (at least that is my theory)

I am 90% sure this is what happend in this case

However - also possible is a static or surge problem and damage to the ecu motherboard. Care must be taken when flashing to observe normal protical of working with sesnsitive electrical parts.

Hopefully, I can resolve this condition for you

 

Welp, like I said you should see our ecu's on friday. Also can you do anything about the CEL for the secondary o2? And Jason has been getting the 0300 code, do we need to have it flashed by mitsu first or can you take care of that as well? Thanx again man.

BTW I PM'd you that convo I had with the guy earlier that I was telling you about.

 

Hopefully I can fix it for you

As for the 0300 CEL fix - chekc out the Buschur Racing CEL eliminator

 

If you flash a computer with an 04' in an 03' box ..it wont start then stop with it dumping fuel. Its not a bad flash, as i've used it many times before. The person that had the flash also did his cams, which on the phone discovered that his cam angle sensor was backwards .. so i dont think anyone should point blame until we figure out what went wrong. I can tell you one thing, he has an 03' flash which i've used prob 150 times, and had reflashed it again when we thought something might of happend with it. ... Same result. I told him to take it to the dealer then see if the car starts with their flash,, but i guess he's using al, which wont help his problem..

hmmm> interesting~
