I have an '03 350 Mag MPI serial 0M354722 that has the PCM 555 module. Does this have Thunderbolt V ignition?

Thanks to all!!

No. The ignition timing and mapping is done by the PCM555 module.... It uses information from the crank position sensor, coolant temperature sensor, Manifold pressure sensor, knock sensors and a few others to determine the best timing....

No, it called a ECM 555 Ignition System.

Nicknamed Triple nickel.
