Re: ECM #
This got me to thinking, my neighbor has a big block (454) rollback that has
a 747, but I didn't pay attention to the rest of the numbers. The thing is
it does not have a knock sensor. No wire in connector, so it appears that it
never had a knock sensor. I read the bin and the knock tables are zeroed
out. It also idles in open loop. I think the bin is anty, have a copy of it
at home.
