does any one know why this damn things pops up? the dealership reflashed me and it went away, and when i started to tune my car it came back, does anyone know how to make this ****e stop?

 

What year is your car?

Email your Rom and i'll take a look at it.

Pm for email.

 

Sorry for the brief threadjack but Lucas found a new P0300 fix for the 05's than basically does the same thing.

The ROM is labelled as a 96940013, but it can be defined as an 11 and it shows everything perfectly.

I have found with quite a few of the cars I do that some seem prone to the p0300 where others do not. Things to check include:

Idle timing is not really high
Coils arent ancient
Clutch/TOB isnt rattling

There seem to be quite a few different ideas as to specifically what sets it off but I honestly cant say because I havent had a problem with it. There might be some relation the ECU peripheries that I am using and how I have them set up. I am willing to take a look as well.

 

he idol timing is high as that is the only was i could get my cosworths to idol right (12 degrees)
coils have been replaced
and the car dosent has a different style TOB ( tilton clutch) but the clutch does have the double disc rattle

if you could both send me or PM me a e mail address i can send you my maps

thanks
the evo comunity saves the day again

 

lower your timing... raise your idle to about 1000 to 1100...

 

the idol is already that high, i bumped it up a degree as a time until it idoled about right, now i just gotta tweak the AC maps so it idols right with that

 

Well I would take those 13 & 10's out since the car actually doesnt idle there anyway. Evo's idle at about 25-30% so I would raise the line of 6's there to 8's max then go to the ISC table and in the 77 and 82* area where its now at like 22 and 20 steps bump them to 80 or so. A stock IX is 100 by comparison. I would try that and see if it "stays" fixed. If not I happen to have the even newer version of the P0300 fix (the 96940013) you could transfer everything over onto if you wanted. I really think that the P0300 is a side effect of being modified, like an error table we cant always see. I know of a few IX's that as soon a tuned map went on them they would kick out the CEL and put them back to stock and they were fine.

 

if you could send that map ill try that as well as switch the other things u were talking about, thanks john

 

Well unfortunately there isnt a finished xml for the type 13 yet. I am still working on making sure everything is the same. I associated it as an 11 in ECUflash and while it shows up and all I am comparing all the addresses between the 11 and 13. Start with that stuff I just mentioned though and see if helps get rid of the P0300.

 

Lower the Idle timing to no more than 7*

 

if the timing is any lower the car stumbles at idol like its gonna die, i started to bump up the timing from the standard 5 one degree at a time untill it idoled right

 

john as soon as i get out of bed and walk to my car im gonna try this, on the ISC tables i made the 77 and 80 areas on all three of them the same lets see if this helps

 

well john it worked and idol idol vacume went down to a hair above 20 and held pretty rock steady, but once i turned the car off and started it back up its like the changes to the ICS didnt save cause the idol vacume went right back to 10....any ideas cause i dont feel like flashingmy car everytime i wanna drive her around
