I've had a recurring CEL after having my chip flashed, which reads:
Troubleshooting P0605
Definition
Internal control module read only memory error
or
(ROM)
Explanation
Failed ECM
Any suggestions would be appreciated.
The year and model of the car is always important in these conversations, but P0605 is EEPROM communications failure in the DME.

Thanks, gents. It's a 1998 base Boxster. I had FabSpeed install their race exhaust, headers and CAI, flash the chip. They did a great job and are trying to find the root cause of the issue but I live several hours from their shop.
