Trying to help our local volunteer fire company - they have a 1991 Chevy 3500 stepvan 454/auto. Runs like crap, a local dealer replaced the ecm and determined that the MEMCAL is bad.

I have been trying to use this forums' BIN Search...but only get errors code. Then tried to locate the ecm and bin via forum "search" results are negative also.

Anyone have a copy of bin:

AWAU

ecm 16154301

Would like to drop in an adapter with burned prom.

Thanks
