RB20DET random stuff

[bades]

Alrighty guys.... I have just a few questions... I have searched alot and cant find any write ups...

I have an Autometer Narrow band Gauge that Ive had for awhile that i bought when i was young and dumb.. my question is can i use a narrow band gauge on my RB20 even thou it has wideband sensors....

also my wideband will be here in a week or so.... and can i just remove the stock O2 sensor without bad things happenin... heck i know on my buddies sr20 he doesnt have a sensor and his car ran fine...if itll mess things up im just gonna wled a bung in....

also my car sits at 15-16in of vac at idle but while moving the car is at 20-21 in of vac..... ive searched for leaks and cant find any yet... but i do know my bov diaphrgm isnt sealing correctly and its leaking....

[eh?]

What kind of wb02 do you have?

If it has narrow band simulation you may be able to use it to run the gauge. You can use the narrow band sim wire as a replacement for the stock O2.

From what I've seen:Idling high with low vacuum = vacuum leakIdling low with low vacuum = retarded timing
