alt fire order camshafts?

[Scarface]

can the tune be changed to run this camshaft or hardwire need to be done?

Harness has to be re-pinned. There is no firing order change available in the Delphi ECM's

But really...its so easy. I prefer re-pinning anyways, because then you dont have to be "careful" which tune you're loading into the ECM.

ok cause I was looking thru my lly tables and didn't find anything on it. ok that is easy had to rewire my injector number #2 from ficm to injector on my shop truck. cause of the connector had a issue. then the new one from gm had a bad connection on the terminals and it got hot. thanks for answering my question.
