A question on ECM's....
for ECM 1227747 there are mant diffrent broadcast codes like ASDU and ASDZ?
A broadcast codes is specific to that vehical? example..a broadcast code ASDU is for a 1991 Chevy C-1500 5.7L V8 Auto, and a broadcast code of ASDZ is for a 5.7L automatic? Is this correct?
(See info below from
http://www.cruzers.com/~ludis/c3xref.html#1227747)
Is a broadcast code the same as a PROM?
I have a manuel tranny in my Blazer. Should I not get a 1227747 with a broadcast code of ARHT or ASDW? Are they hard to find?
Or, does the tranny type of the broadcast code not matter in my situation?
Thank again folks for all you help!
