Webguy, I have Dynoflash. I am getting it reflashed back to stock before I take it in to the dealership though. It was a good mod while it lasted but now I've got this p0300 crap to take care of. My dealership is fairly mod friendly, but I don't think they would be too happy with a modded ECU.

I took my car to get flashed a few weeks ago at the dealership and they said my ECU would not flash. They blamed their equipment and asked that I come back another time to get the updated flash.

I have gotten the transmission vibration in both 4th and 5th gear although it does happen a lot more often in 5th gear than 4th.

 

I noticed i'm getting the 0300 error code much more frequently when i have my roof mounted Thule ski rack on my car. I guess the wind resistance from the ski rack is causing the engine to work a bit harder at highway cruising speeds and then i get the 0300 error code pop up. Anybody else notice the same thing with their bike/ski racks? I wonder if Mitsu is gonna void my warranty claim due to aftermarket racks

 

uh-oh, got my reflash a few days ago, just got another SES.... don;t know what code yet... will go to dealer tomorrow....

 

Good deal. Interestingly, their reflash equipment failed to update my ECU the first time around, though I've never been reflashed/touched the ecu. Sometimes the data xfer just fails.

Keep us posted!

I finally got this flash. Seem to be working fine. No cel lite for this misfire, don't feel it.

I do worry about few things tho. After the dealer flash, my car idles funny upon start.

It start 100 rpm less than what it use to start at. This is given that the engine is warmed up then stopped then on again.

it used to rev at 900 rpm upon start, but now at 800 rpm. Feels like the cars slower too for some reason.

I'm sure it's nothing but no CEL. I just have to worry about my p040 cel. lol

 

CEL will not make you car slower, only seems like it, I made 350AWHP on a cell for p0300 (Noisey cams) and no cat.

 

ok.. so i got my flash a few months ago... and the CEL came back on 1 day later. It stayed on for about 3 months... and then one day it just disappeared. I've put about 3000 miles on it since then, and it has yet to return... WEIRD. This is the longest i've ever driven the car with no P0300.

 

YHAOO!!!!!!!!!!!!!!!!!!!!!!!!!! I can't wait to tell you all what happened.

 

Me too! Well, soon anyways.

 

glad to see you guys can broker some sort of a deal. hope it all goes well for you. looking forward to good news about mitsubishi.

 

I can't wait to see the news coverage of Mitsu's lemon claims for 2004.

 

Took my car in for the PCM flash this week. So far it's working great, and I have about 250 miles on the car with no CEL. If it comes back on again I will be raising holy hell at the dealership.

 

Do tell us!

 

naucrx, it took me about 300 miles iirc before it happened again. Good luck!

 

still having plm with p0300. i did went to the dealership and have them to flash my ecu and after that it went out.. but after abt 100 miles later it came back on and still p0300.. what should i do? anyone out there any idea?? Thanks!!
