These are called the A (address) and D (data) busses. On a typical 256k eprom, there's 16 address lines and 8 data lines.
With how small the eeprom is though I'm thinking it might store some data on that & some on another?ĮEC-V EL Eprom.png (699.57 KiB) Viewed 11284 times So I think I'm getting somewhere but been told the layout of these eeproms from intel have offset pins & will need an adapter to read at best & then obviously need an adapter for ostrich too! If I put the eeprom in the socket it runs fine, if I take the eeprom out of the socket the car won't run & fuel pump stays on & fans telling error, then if I put a tuned file on J3 port without anything in socket it runs fine! I don't know what the eeprom type is to even get a read off it! I've been mucking around with an EL EEC-V PCM I have & managed to get the eeprom off that i'm guessing/hoping holds all the Calibration data which comes in 256k 4 banks of data.Īnyway I pulled it off & socketed it in hope to maybe adapt an ostrich for realtime tuning! I thought I better put this in off topic as I didn't want to taint GM stuff with the blue oval Found On Rubbish Dumps!
