What are your thoughts on the Scanmaster for the LT1 motor? I was contemplating the purchase. Is it necassary, worth the money? What are your thoughts? How about the best price?
Read through my online ScanMaster guide and decide for yourself. If there was anything that helped my understand these cars, and how they are controlled, it was watching the ScanMaster. Even though I no longer use the stock PCM to control anything other than the speedometer and the idle air control, I still have parallel inputs from all the sensors to the PCM so that I can monitor engine conditions real time, with a bright LED display on my steering column.
Its the small black box (standalone unit) with the red plastic face, sitting on my steering column. Allows continuous real time readout of about 20 engine sensors and parameters, including:
-MPH
-RPM
-Coolant temp
-Inlet air temp
-Barometric pressure
-Manifold absolute pressure
-TPS sensor volts
-Throttle position %
-Idle air counts
-Mass air flow
-Fuel correction "cell"
-Left/Right O2 sensor millivolts
-Left/Right injector pulse widths
-L/R long term fuel corrections (BLM's)
-L/R short term fuel corrections (INT's)
-Spark advance
-Spark knock retard
-EGR duty cycle
-EEC purge duty cycle
-A/C pressure
-Trouble codes (will only read 94/95 OBD-I codes, not 96/97 OBD-II)
During a WOT pass, it will record the maximum knock retard level, the minimum O2 sensor mV's and the speed at which each occured.
