OK. SO. I ditched the stock explorer cam and went with a comp cams xtreme energy cam. The cam is 4 degrees advanced, and when using the cam sync tool, the syncro is pointed slightly off to the passenger side when it is lined up (as opposed to straight ahead with a stock cam).
This would mean that the computer is seeing the cam at zero degrees, when in fact the cam is already moving valve train parts. Would I simply leave it like this, or do I have to manually advance the syncro so the PCM is in sync with the cam? Or would that be dealt with in the SCT tuning work that has been done?
Second half of the question. This cam was listed on Comp Cams website as a good H.O. Replacement cam. I have heard the H.O. uses a different firing order than the standard explorer engine. Would the firing order also be changed with the tune, or would I have to manually swap plug wires around on the coil packs and injectors?
I have never been quite clear on how the same crank can have two different firing orders by just changing the cam
