1987 4.3 Z engine ECM/PROM Verified

[peter paul fenske]

Hey Larry and all

Try the the 747 and calibration you got in your
truck. The peak and hold drivers will run just
about anything. Wire in the tps and CTS sensor
Leave the air valve alone. If you end up changing
base pulse it is a small change. Do this if
your blms are way out

Try the simple thing first. Other wise you can
prob go to the 730 cal I am using but it requires 
a bit of a rewire at the ecm connectors
