Question on speed density
I'm currently running Speed density on a 2002 GMC with a 6.0 engine with that custom operating system. I'm trying to get rid of the PO 102: but I understand the MAF has to fail for speed density to work. Is there any way the P102 can be removed or perhaps I can hook up the map sensor again so that the code does not show up. Any help would be great!

If you are referring to the engine light from the P0102 code, you can disable the MIL for the code and it will run in SD mode and still have the MAF failing.
