disable P0300 test
So is there anyone that knows how to disable this that can either explain it to me in english "as i dont understand these codes etc" or just disable the p0300 code for me on my rom??
very simple just add the code to your rom id xml file then open up your map and at the bottom as in the picture added to the post you'll see it
just edit and paste what you should put in as instructed and then flash your evo
Stop right there. You are facing a very steep learning curve. Find someone in your region who knows what they are doing. It will be worth the wait and the trip.
In the meantime, get a "CReader" brand OBDII scanner (check Ebay) and leave it plugged into the OBDII port. It will fix your P0300 problem in the meantime.

Next, you'll need to find the ECUFlash xml file for your ROM. Do you know how to find the ECUFlash program on your hard drive? Its located in:
c:\Program Files\OpenECU\EcuFlash
In the ECUFlash folder, you'll find a folder called "rommetadata". Drill down into that folder until you find the xml file for your ROM. Open that ROM with Notepad and paste in the items mentioned in the first post. Save the xml file, close ECUFlash, reopen it, and the "Periphery" table(s) should be present.
Sorry I haven't had time to help you with this. First thing that you'll need to do is determine the ID of your ROM. You'll need to open your ROM in EcuFlash to do this. Open it up, and go to the "ROM Info" section. You'll see the ROM ID there.

I appreciate it for sure. I will PM you my ROM ID as i know exactly where thats at
I may just have you put the p0300 disable in there for me so i dont mess anything up if you dont mind doin it for me. And "learn" with some other ROMS that I have here on my desktop Tuning is no problem... been doin that for years. But this computer code etc is a totally different ball game lol. Thanks for taking the time out and explaining it a little better for me and not just telling me im stupid basically

As I would like to fully understand this and be able to do it myself.

Will give you a better understanding of how to access the .xml and modify your rom based on one of Tephra's patches.

Hot start, warm start, cold start, no start, whatever start, got no problems here whatsoever [so far]. (I even disable the other annoying p0401 code that I'm getting.)
Thank u, mrfred. U tha man.

You sure you don't have one of the hoses loose back near the throttle body or egr? That's boost leak if you do...you know that right?
I had a "computer smart" friend of mine help me put the Periphery tables on the new version 1.4 of ECU flash. I disabled the P0300 code but have yet to flash my car... I just got home and its late and COLD!! So I will do it in the morning and make sure that annoying code is gone. 
Have any of you found any bugs with ECU Flash 1.40?? I was previously running 1.34 and never had any troubles. I hope going to 1.4 was a good thing...
