Steve, Congrats! on the 1st start-UP. you need to specify a specific year EFI platform. for the eprom.
Example 85 = 2732A<> 86 - 89 = 27C128<> 90 - 93 = 27C256<> 94 - 95 = flash = direct programing<> 96 1st year true OBD II = direct programing. you will need a tuner! you will need a lot more than simply raising the idle<

that is correct. the OE is burnt via UV. the mod is DEsoldering. then installing a EEprom. you can install Atmel AT29c256 OR 512 chips. actually slightly quicker access time. this allows UNlimited burns to the EEprom. along with CATS or tunerPRO and a USB to OBD I adapter OR OBD I / II "Y" adapter. data logging is a must. capturing with something like Datamaster. and sending the results. off to a bench tune. Close. or actually doing live tunes on a DYNO. for Optimal results.
