Someone want to test airflow check disable mod?
Hi Guys,

I havn't tested this on my car - but I think it should work ok.

This is for 52680015 -> 52680020

Code:
<table name="Disable Airflow 0xB090 -> 0xFF00 #1" category="Misc" type="1D" address="0x393a0" scaling="Hex16"/>
Change 0xB090 to 0xFF00.

Let me know if you get any CEL's or anything funny before driving hard.

Also be good if you had a WB02 to make sure your AFR's are still in-check

Cheers
D.

P1233, P1234 and P1235

ORLY?

I think I have my airflow tables dialed in well now but for those that still trigger limp mode this would be a really nice way to escape them!

oh wow...

Easy way to test is to just drop the tables down about 20%

I can test this this weekend

Now what about the torque maps?

cool!

i am more worried about unexpected side-affects from disabling this section of code... so take it easy

yeah I had a look at the tq maps and they seem to be buried more - let me know how this goes first

The stock torque maps 1,2,3 are the same as the airflow maps 1,2,3. Wouldn't disabling one disable the others?

No because it references a different routine AFAIK. It gives seperate CELS.

Also, there are additional torque limit tables for the SST...

Were they getting triggered before you disabled airflow?
