I had previously dropped an "0001" bomb into periphery 2, which puts a "1" into Bit 0, and a "0" everywhere else. I believe that takes care of the evap, secondary O2, etc./

 

Im not that familiar with what that means lol.

step by step at how to do that? do i leave the sensors for the EGR plugged in

 

bumpy!

 

If you add the "Periphery Bits" code to your XML (see post #1), you will see one of the bit tables labeled as "Periphery 2". Basically, you use the increment/decrement buttons ( [] ) to toggle all of these to "0" except for Bit 0 (leave that one as "1"). That will take care of it.

As for whether you leave the sensor plugged in or not is up to you. It's probably better to leave it plugged in than to have loose pigtails dangling.

 

ok got it!

thanks a bunch ted, greatly appreciated!

 

This is just an update to let everyone know that after 6 weeks I still have absolutley no issues with disabling the P0300 code. I used to get the ses all the time for this error.

 

mrfred- Does disbaling the p0300 effect ay of the other P03xx series codes? specifically p0301, p0302, p0030 and p0304 ?

 

It kills them all. :-)

 

Yeah that's what I'm afraid of. I hate the generic "something is wrong but I don't know really what." of the P0300. Which is why I'd like to kill it, but not necessarily at the expense of the "I know what happened and it was in cylinder 1,2,3,4" of the 301, 302, 303, 304 codes.


Course, now that I think about it, those codes could really only tell you if a plug or coil is bad.....possibly injector....I'd sure feel a power it if I lost a cylinder or two, so maybe I don't need those anyway. hmmmmmm......time to reconsider this.

 

I gave mine the bomb and will simply re-enable it if I have a problem I need to check on

 

Interresting option also, thx. Maybe when the V6 comes out I'll kick this to the curb.

 

A little confused here. I'm running ROM# 96940011 for an '05 VIII. I've already added the 1.35 periphery bit code to my ROM, and edited bits 4 and 5 in Periphery2 accordingly. My question is do I also follow the instructions below or am I done and ready to reflash?

"If you are using an older version of ECUFlash, then copy the entry shown below to your XML file (save the xml file, and then relaunch ECUFlash):

<table name="ECU Periphery2" category="ECUPeriphery" address="fca" type="1D" level="1" scaling="Hex16"/>

When you open the Periphery2 entry, you should see: EFDF. Change it to EFCF by typing "0xEFCF" (without the quotes) and then pressing return. If you see something other than EFDF, post it up here, and I'll give you the correct value to enter."

 

Both methods accomplish the same thing, so if you were able to directly edit the bits with the periphery bit table, then you're done.

 

Thanks for the clarification mrfred. And thanks for this fix!

 

How do I open my ROM to fix this? I've had the p0300 for years and I run with an ODBII reader in my car just so I can reset it as I drive.
I have a 03 evo8 and EcuFlash 1.4... I just don't know how to open the xml ROM to modify that part of it.
