Quote: And one more time from a guy who's worked on allot of Fuel Injection... My vote is a OE PCM because they have diagnostic capabilities including freeze frame PID recording & trouble codes.. With aftermarket systems you need your laptop hooked up & you need to be viewing the proper parameters if & when something goes wrong... Hard faults are easy, intermittents can be challenging but if you've go an OE PCM it will detect a fault, set a code & record the data just prior to, during & after the event....
It looks like MS3X Does all this as well, I can set parameter for "Check engine light" and the MS does real time logging non stop anyhow for as big as the card inserted is.
Plugging in a laptop is no different to me then plugging in an OBDII scanner except with the MS I get real data instead of just a trouble code.
I guess the LS tuning software does something similar??
