Hi,
trouble is that ecm throws code 43.Some specs about car:
-85 Camaro with 355 engine(880 rollerblock),EQ vortec heads,stealth ram,hot cam,headers etc.ECM is -870 with custom prom.Knock sensor at that engine is Standard Motor KS7(-88 350 tpi)
Doing some trobleshooting.Measured from esc wiring harness:
-engine rpm~2000 knock sensor gives 300mV AC(GM shopmanual says if more than 80mV,problem is defective ESC module).
So if I replace that defective ESC module,should I put there Standard Motor LXE9(used at -85 Vette and F-body tpi both have -870 ecm) and -86 Vette and f-body (tpi engine and 165 ecm) OR
Standard Motor LXE6(used -88 and -89 Vette and F-body with 350 engine)
Another question is ,what is the point of that they used same knock sensor and esc module at 305&350 between -85 and -86,but changed them at -87??
(is it roller block or what)

Nobody knows?????
