Just installed the wong chip and did not find any h protector and the chip did not look original (+dme already open). Donprobably was already chipped.

Look at the pic of the chip, would welcome your thoughts

Can’t help you decipher who programmed that chip, but all is good now since you have a Wong chip installed. Love mine! Improves the sub 4000 rpm drivability of the car.

Hi, the chip shown is a generic 256K-BIT [32K x 8] CMOS EPROM. As the car ran with that chip, it was programmed with some someone's firmware. Typically a label would be applied with that info Without a label, it is a mystery although by reading the program on the chip, sometimes programmers use a few spare bits to put some info on the chip such as their name or company.

Did not drive with the wong chip but could already see idling improvements
