Need quick help on disabling patch for P0443
I'm finishing the prep on OKIX's car and after re-installing the Intake Manifold, I'm getting the P0443 code and very rough idle. I could swear that I kept a printout of a disable value in the patches for Periphery4, but can't find it anywhere. I've searched for nearly an hour and can't find it in the threads. Could someone help me out. Thanks in advance.

Tom, P0443 is Evap/egr?

If it is try periphery 2 (fca or fba...cant remember) and change the value from 0xefdf to 0x8d89. The connectors for everything need plugged in, but nothing actually has to be working.

I've got Periphery2 set to EDDF, so you're saying that 8D89 on the 8859 version?

Is this what you're talking about needing?

Code:
<table name="EGR MAP Offset #1" category="MAPSensor" address="4936" type="2D" level="1" scaling="uint8">
	<table name="RPM" address="74de" type="Y Axis" elements="9" scaling="RPM"/>
	</table>

	<table name="EGR MAP offset #2" category="MAPSensor" address="4946" type="2D" level="1" scaling="uint8">
	<table name="RPM" address="74de" type="Y Axis" elements="9" scaling="RPM"/>
	</table>

	<table name="EGR Pressure Diff" category="MAPSensor" address="1B7C" type="1D" level="1" scaling="Volts16"/

Cheers-

it's the disable function to the Evap that give the P0443 cel code. I could swear I had it. JB, is the same Periphery used for both EGR and EVAP?

Perph 4 is set to B980
Perph 2 is set to EDDF (This disables Rear O2 I think)

That's how I've had it set, but it just started throwing the P0443 code. Didn't do it at Shreveport races. Don't know why it just started, but I had the intake manifold off and maybe something got unplugged, I'll have to check that too I guess.

Yeah from what I have been able to decode from Bez' orginal table and the JDM and EDM roms that dont have EGR/EVAP thats the value you want.

EDDF doesnt do the trick

8D89 or 89DF, Its the 89 part of the bit thats important.

I use 8d89 as does lucas and thats all off our cars

To disable the egr test, periphery2 is changed from efdf to eddf based on MRfreds posts.
