OK, digging into more now... Is there a way to analyze the EPROM data I have? Just curious where I would find that data from the chip itself..is there a specific location I would look in the data?
Great stuff...checking the links now! Thank you for assisting!

The typical file begins with calibration data. There is a program ID known as the Mask ID which can be found at location $0008. If your chip has a mask ID other than $AA we may be able to determine which program was used. This would be a big step in determining whether or not a stock ecm could easily replace it.
I have the file, just trying to figure out how to track it down... I tried an online tool and it couldn't find the mask...poking around in my eprom programmer buffer now to find it...

Location is the eighth byte after the first. Could be C008, 0008, You could load the definition into Tunerpro with one of the $0E definitions and it will show the mask ID.
I think I'm doing this right..loaded an xdf of 0E_tpv4_v200.xdf (any reason for using $0E definitions?) in tunerpro, opened my bin and got:Originally Posted by 1project2many
PROM ID: 18976
Platform ID (MSW): 1C86
Platform ID (LSW): FFFB7
Checksum: 018E
Mask ID: B6

Does that info relate to anything 'stock'? Does that Mask ID mean that I have a '$B6' mask ID?
