The 86-89 F and Y bodies were among the first EFI computers used by GM that featured a Mass Air Flow sensor (MAF) for air metering.  P4 generation ECM, 160 or 8192 baud ALDL communication (depends on code mask), “memcal” with 27C128 EPROM.  Many of these ECMs feature a cold-start injector.  They can drive up to 8 injectors and a single coil with distributor.  There is no transmission shift control on these ECMs. The 1227165 and 16198259 ECMs can be used interchangeably.
