I’ve had this p28 for a while got it with a parts car plugged it into my car it turns on so Ik it works. Didn’t try driving cause it’s an unknown tune. My question is does any know what chip brand this is?

The chip is an SST. The small board you are holding in the photos above is merely a datalogging device with a serial port to connect externally. Serial connectors are older technology, so I am not sure what the brand name of the device is. You cannot TUNE with this device... you would have to find a tuner who can burn chips and they can alter the programming on the SST chip.

Thank you. That’s what I wasn’t sure about. I’ve been searching but couldn’t find anything on it besides it being chipped.
