Ok.i was told by someone to uncheck the chatter box. That there is no heartbeat either. Is this correct? Also for suspend , i didnt see anything about that in the A1 file. So should i uncheck chatter? Should i then set it for no heartbeat? I was told my 91 350 tpi had no heartbeat. So, for suspend it should be $F4,$56,$08,$AE and resume should be $F4,$56,$09,$AD right? Please let me know.
