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
