Hi guys got a mercruiser 350 mag mpi with the ecm555 ecm got the mercruiser scanner have updated the unit with new chips and new adapter lead the scanner gets power but can not determine ecm type and come up with an error check wires have checked wires with meters too ecm plugs all okay
 
I recall someone somewhere recently posted about updating their chips inside the scanner and it wouldn't read the engine 555 ECM....They said they called rinda tech, Rinda said no way it's a chip issue, after some negotiations were made, the scanner went back to Rinda tech and they found the new chips inside to be bad....Maybe you have a bad set of chips? Maybe try putting the old ones back in for testing?
 
Old ones never worked on the engine as it was an older software these will read a Diesel engine but you select your own ecm type that way so a little bit stuck
