Like the subjects says, I am trying to get the “Max WGDC cold engine / CEL" table for ROM ID 96420008. I search on the forums and found nothing. If someone knows the address and definition to add the “Max WGDC cold engine / CEL" table for ROM ID 96420008 please post it. I believe it may be the same as the one for the EDM Evo.

I have a GM 3 Port in my 2004 EVO and the default 62.5% WGDC Value is OK for the stock BCS but too much for the GM 3Port. Anyone knows?

Post edited to include details on how to make the changes to ROM ID 96420008.

To add the "Max WGDC Cold Engine/ CEL" functionality to ROM ID 96420008 you need to modify the evo7base and 96420008 files on ECUFlash.

The changes are as follows:

Define new scaling on the evo7base file by adding the line below:

<scaling name="WGDuty16" units="%" toexpr="x/2" frexpr="x*2" format="%.1f" min="0" max="100" inc="0.5" storagetype="uint16" endian="big"/>

Add the table on the 96420008 file by adding the line below:

<table name=”Max WGDC Cold Engine \ CEL” category=”Turbo” address=”2200” type=”1D” level=”1” scaling=”WGDuty16”/>

Open ECU Flash and change the default value to the one you desire. The default value is 62.5%; I used 30% on my GM 3port solenoid setup. Now the car can only boost 15 psi when cold and after it warms up it goes back to normal operation which in my case is 22 psi.

Enjoy!!

 

try 0x61d6 for the table and 0x69e6 for the coolant axis.

 

tephra he is asking for the single cell table, shows 62.5% WGDC as default.

 

I see said the blind fox.

 

Try 0x2200

 

I'm pretty sure that table doesn't have anything to do with engine temp. I think its only for some fault condition.

 

^ yeah which is why I got confuseled..

 

You guys sure? I've had a couple guys try to boost on a stone cold motor and their WGDC was limited, or say they said.

 

I added the following line to the 96420008 file and got a 0.0% so I guess that’s not it:

<table name=”Max WGDC Cold Engine \ CEL” category=”Turbo” address=”2200” type=”1D” level=”1” scaling=”WGDuty”/>

Is this the correct way to add the address in ecuflash?

 

RL - Don't forget the WGDC vs Coolant temp table...

R135 - You need to define a new scaling:

<scaling name="WGDuty16" units="%" toexpr="x/2" frexpr="x*2" format="%.1f" min="0" max="100" inc="0.5" storagetype="uint16" endian="big"/>

And change your above definition to WGDuty16

 

tephra,

In my evo7base the WGDuty scaling is defined exactly like you are defining the WGDuty16. So I do not need that definition.

BTW according to mrfred the WGDC vs Coolant temp table are not defined in ROM ID 96420008. That's why I am looking for an alternate way to limit the WGC when cold.

 

But that is already 0 when below 122F

 

racer135 - are sure you have uint16 not uint8?

Also my first reply has the coolant vs wgdc table locations...

 

tephra,

You were right I had unit8 and not unit16. I did add the definition and change the line to WGDuty16 and now address 2200 reads 62.5% so I think thats it. Is that the address for the EDM? Any other way to test it without trying to overboost when cold?

Thanks a lot!!!!
