Dear list,
Looking for some help, wish to program the Jetronic injection system. I have a
LE3 version fitted to a Fiat Uno turbo. The pcb is fitted with a socketed 16
pin IC (chip), I believe likely a TTL PROM or similar, and I know people have
changed these for different injector duty cycle - fuel maps etc. I have a
standard chip and wanted to experiment. My question, does anyone know and
please tell me what the IC is so I can purchase some blanks and start
experiment? I have access to EPROM and Prom programmers. The OE programmed
chip is a Signetics chip, with number: B57586 2nd and third line: 9001 8934.
Any hints or pointers would be very much appreciated.
Thanks,
Martin
