if the car has been previously tuned opensource and now running accessport, can Subaru detect the change of the checksum if the "0x5AA5A55A" trick has been used for the DBW 32 bits checksum (located at 0x00FFB80 for my sh7058)?

We understand that many users want to have fun, but would rather not have fun at the cost of a voided warranty due to some form of "black box" or flash counter. However, the Subaru ECU is not able to track such information. Once you uninstall your AccessPORT your ECU is 100%, OEM, Stock.

You can install your AccessPORT with confidence!
