This OBD-1 ecu doesn't use a 27C256 memory chip like the rest of the class do. This Ecu utilizes a chip very similar to the 96+ OBD-2 ecus do. It could be done but the programming equipment will end up costing you a lot more and all the chips for this are a one time burn only. The ecus that use the 27C256 (PROM) can use the Atmel 29C256 (EEPROM) or any other 29C256 (EPROM) although not recommended.
The PROM is a one time burn chip. Stands for Programmable Read Only Memory. Due to electronic interferances these chips could some times not get burned properly and will endup costing you another one since they cannot be re-written.
The EPROM is a PROM that is erasable. This type of PROM requires using an ultraviolet light of the correct frequency in a proper enclosure for a certain period of time (generally around 5-15 min.). Doing this while pulling over to do a minor tuning adjustment with your laptop is totally out of the question.
The EEprom is electronic erasable. The programmer can erase it and reprogram all at once at the cost of no more than an additional 10 sec!
