sorry to post twice my computer is acting up and i didnt finish.
Here is something else that may be helpful to you.
The alternative, a non-EPROM ECU, does not have an EPROM. Instead, the program is stored inside the microcontroller itself (technically, in embedded EPROM memory that is part of the microcontroller). This makes it hard to change the ECU programming, because the microcontroller needs to be replaced. These are difficult to get, and require special programming tools that are equally difficult to find.
