Hi All

        Nieghbor came over and wanted help on his 82 Camaro. Local shop told
him that he need a esc module because timing didn't advance. Module is well
over $100 at GM, only source. Check timing and found it advances with or
without module attached. Main symtom appears to be idle varies widely. I
suspected module is for retarding if pinging is sensed. Can anyone help ?
The 82 has cross fire injection, all simple tune up items have been done.
Car does pass smog test for calif.

Thanks Vance
