A1C_230830.xdf missing PFEHP EGR Type SW

Was it removed for any particular reason? A1c is set to Sonic by default. I am running a PFE setup.

I'll see if I can find it. Do you know what EGR hardware came from the factory with A1C? I am assuming it was sonic but if the old address was wrong, I have no idea.

I believe it is located at BC7D instead of BC7E. Maybe you just fat fingered it?

Code: Select all

223f: df,09               je    224a             if ([bc7d] != 0)  {
2241: b0,00,7d            ldb   R7d,R0           R7d = 0;
2244: c7,e6,44,00         stb   R0,[Re6+44]      [2c4] = 0;
2248: 20,06               sjmp  2250             goto Sub_2250; }

224a: ef,98,3c            call  5ee5             Sub_5ee5 (); 'EGR sub is called from here
224d: ef,6a,3d            call  5fba             Sub_5fba ();
