Tom,


I agree the Digitool is very handy.  Mine is the Digijet version so the 

readings may not match perfectly to your later model Digifant.  I asked 

basically the same question about eight years ago - wish I could 
remember all the answers.  The Temp 2 reading should start almost the 
same as the Temp 1 and fall off as the coolant warms up.  The O2 
reading should bounce around roughly centered on .50.  If it stays 
consistently higher you're system is running rich, consistently lower 
it is lean.  On the Digijet the reading will start about .40 and stay 
there until the exhaust warms the sensor, I think the Digifant with the 

heated sensor starts working sooner.  My AFM reading is typically 
between 1.50 and 1.65 at idle with the engine fully warmed up.


The TPS LED should be on when the engine is idling (no foot on the gas) 

go out as soon as you touch the pedal and come back on when you reach 
full throttle.  If it doesn't do this the Throttle Position Switch 
needs attention.  The FI LED should flicker at idle and gradually 
become steady as the rpms climb.  It will go out when you suddenly let 

off the gas then begin to flicker again when the engine slows to idle 
speed.
