What kind of changes are needed to run speed density

wesam:

I have not seen SSpdDmon sign on this forum in awhile, so here is my view.

I don't believe you have to worry about C2904. I.E., I have failed the MAF just like AUTOVE states. I also don't change the Processing Enablers..you need to throw a DTC to be in SD.

Thats my understanding..:).

Thanks a lot Shwan

Agree,

Just turning P0102 to NO MIL is sufficient. C2901 to 2910 can be left at factory parameters (this then allows you to run SD or maffed as you like).
Check the 2004 HSV GTS tune file in Holdencrazy which is single-spark SD.
