Or any other Guru's of course

Can you make a mod to fix the VIII's p0300 issue? This is the one that some users have to use the C-reader to get rid of that is probbably caused by some type of vibration. Like in enginuity / rom raider where you can just permanently turn off a code.

 

whats p0300 for? misfire or something?

trouble with evo's is we don't know very much about how the DTC codes work (in the code that is)

ill have a look for it after ive done with V5

 

po401 here. i have to keep my creader plug all the time

 

just disable it...that's an easy fix.

 

Mr. Evo IX what ecu ID do you have?

 

tephra. its a random mis-fire. its caused by lighten flywheels (thats why i've come to believe). its really annoying too. if you could make a patch to disable the code all together or somethin that would automaticaly clear it that would be AWESOME . its really annoying have to have my laptop out everytime i go for a long drive cause that stupid thing comes on.

 

Is it a perf affecting CEL? ie does the car run differently when its ON?

 

its not performance effecting.

 

yea the car will misfire and vibrate. its really annoying. i just bought a creader that will automatically erase it but it would be awesome to get one with a patch so i dont need to use it .

 

so the misfire is real?

what romid u guys using?

 

Make sure the egr valve hasn't become unattached to the vacuum line. Its a common issue. I've fixed 4 of them on evos here in Houston this month and that was the issue. The line just comes off sometimes.

 

pretty sure it is. im currently using 0015. was using 0008 but changed cuase of the new v5 mods you released

 

and you still get P0300 with x15?

 

Has anyone else noticed that when the periphery 2 is set to 0x8D89 the rate of P0300 seems to drop? I havent ever had a misfire code in my car in nearly 29k even with all the different mods that I have. However one of my friends with an almost stock MR had P0300 as soon as I flashed the car, that would go away when it went back to a stock map. He sold it before I even thought that there might be a connection. He lived in an emissions area so I didnt turn any of that stuff off on his car.

Worth a try for those that have chronic problems maybe.

 

i havnt changed any of those periphery's.
