The 57B30 is for an early 16V Vitara with the 57B00 Volume Air Flow Meter rather than the Mass Air Flow meter used on the Mitsubishi based systems. The 42-pin Denso processor is similar to an Hitachi 63B01 but with some additional counters. I have been able to read this after making a few small modifications to my RomReader PCB.
