Default Reluctor wheel (what do i have)
My computer is 12589462 - 12589161
my engine is a 06 lq4 from a yukon denali xl

both cam and crank are black. So from reading my engine is 24x

so what is my pcm stock programmed?
And if its wrong can you reprogram to 24x?

Computer is an 2005 P59 PCM. There is no way to know what vehicle it is programmed with by numbers. It requires connecting with a tuning product or scanner to determine that. That PCM is compatible with a 24x crank and 1x cam reluctor.
