Here is a picture of the new "165"
ECM with the two new MAF Burnoff and Power Relays wired in to replace the very
expensive ($961) MAF Burnoff Module. The old, now unused burnoff module
can be seen at the lower left, the silver/black box with the 6 wires coming out
of it. Many thanks go out to Mike and his neighbor Dave of Elkton,
Maryland for performing this swap. Full details of how to perform the swap
can be seen at Mike's EEPROM
Project Page.
Another picture of the new "165" ECM
with all the required repinnings completed. The stock EEPROM can be seen
in the foreground (light blue/black) on the left and the custom burned EEPROM
(brown/black) on the right.. I tucked the two MAF relays up under the dash
and mounted them where the old burnoff module was.

Reinstalling the dash pad and passenger side
hush panels after the road test has been completed. The entire evolution
took approximately 4 1/2 hours altogether, and after the repinning Mike started
to burn the custom EEPROM configured to the modifications that had already been
performed on the engine. Timing and spark curves were advanced, torque
converter clutch lockup was raised to 41mph, and the radiator fan comes on at
about 180 degrees instead of the stock setting of 225 degrees. After the new
EEPROM was burned, the engine was run through diagnostics with Diacom Software
and the data can be seen here:
