It uses the high octane spark table rather than the idle spark. B1829, B1821, b1651, b1652, all what seems like all the idle tables are not referenced Whatsoever. You can change the values to whatever you want and log it.... it will act exactly the same. Tries to idle at 500 rpm using the high octane spark table. Its like the ecm loses its mind without the maf. Really frustrating.
