:COMPUTERS:

16183082 / 16206305: Applications include -

VRV6 & V8 Manual, VS V8 Manual, VN/VP V6 & V8 (1227808 is pretty much the same).

Memcal EPROM size for VR & VS = 27c256, for VN & VP = 27c128.

16176424 / 16195699: Applications include -

VR V6 & V8 Auto, VS V8 Auto. 16195699 has special silver plugs, otherwise the same as the 16176424.

Memcal EPROM size for VR & VS = 27c512.

16199728 / 16208257 / 16210672 / 16210480: Applications include -

VS V6 Auto and Manual. Supercharged V6 has a specific PCM, as does the T5 Manual PCM, check the label.

Memcal EPROM size VS = 27c010.

16234531 / 16233396: Applications include -

VT V6 & V8, VS Series III.

Memcal EPROM size VS & VT = 27c010.

09356445: Applications include -

VX V6 Auto and Manual, has Flash ROM, no Memcal.

Flash ROM type for VX = 28F010.

09354896 / 12200411 / 92112087: Application -

GenIII LS1 V8.

Flash ROM type for VTII - VYII = 28F400.

12570558: Application -

GenIII LS1 V8.

Flash ROM type for Pontiac GTO (Export Monaro) = 28F800.

Upcoming VZ V6: No technical details on these yet, these ECM's are quite common on European GM cars (which is what this one is off)

:MEMCALS:

STANDARD MEMCAL:

The BCC (Broadcast Code) on this Memcal is 'AMDD8389'

The Knock Filter board is mounted next to the ROM. Underneath the knock filter is the back-up mode resistor arrays.

AFTERMARKET MEMCAL:

You can see the ROM has been replaced with a custom PCB, these usually have a PLD and a FlashROM and generally cannot be read out or reprogrammed using an EPROM programmer.

WIERD MEMCAL:

This style of Memcal is usually found in Isuzu or European Delco computers, GMH never used them in the Commodore
