I (actually DontbeaRikki) recently installed an
Autometer A/F gauge on my FD3S.

My question is. During operation.
Do you want to tune your car so
the light readings are at STOICH,
when on the gas???

Under normal driving condition on the gas
it reads 1-2 light green in the Rich.

Thanks..

 

mine is the same way, i dont think it matters unless your at wot.

 

I also want to know about reading on Autometer A/F. When idling mine is always on red , which indicates lean, however i can still hear it backfire sometimes. But when it's at wot, it's always at green. Is this ok?
Thanks

 

Normal readings on A/F ratio mtr are:

Idle: No LED's or just 1-2 red at lean end of scale - Not enough exhaust gas to maintain accurate readings

Part Throttle/NO BOOST: reading should fluctuate rapidly between lean & rich - cpu is in CLOOSED LOOP mode

PartThrorttle>WOT wBOOST: should read 1-3 LED's RICH (the higher the boost the more rich it should be)
Mine runs 2-3 bars rich at wot and 10psi boost
