The proof will be in the driving of course , let us know how it goes... they must have some good knowledge to be checking the module out etc - are they a bosch service centre ?
apperently the pcm just tells the fuel pump module when key is matched and when to fire fuel via crankshaft reading and cht reading , and the module on pump does the rest for calculating the correct pulses going to metering solonoid.

is this all correct.

if so the pump cannot alter the fuelling for what injectors its feeding 75/85/90/100ps so does the pump come ready for the right power output or does another signal get to pump module from PCM when pump coding and marrying.
