my setup is this:
90 zc 1.6l dohc and zc ecu
safc, eclipse 450cc injectors
just changed the fuel filter and spark plugs.

the car has a bog in between 2k and 3k rpm and sometimes when its at idle cold, if it is idling a bit too high it will catch something and the revs will drop like a rock and sometimes even stall. this is rare though, but it seems to be getting worse.

settings are around -38 up top
idle is set at -29 - -32 or so because the zc ecu doesnt idle at -38


i have a pm6 that i might try tomorrow and see if the bog still stays.

bog means too rich right?
well i tried to lean out that part of tha band a bit, so i put it at -40 - -41 and its still a slight bog, should i go higher?
it was never a problem before so it makes me think that something is causing it.

my second question is this, i wont be able to get a wideband to tune with for at least 4 months so would it be better to keep with the safc hack or go with a pre tuned chip burned with turboedit with someone elses setup.
which would be safer?

 

wideband...buy one, borrow one, something...

 

maybe the cap and rotor needs replacing?
could it be bad gas? (91 octane)
should i change out the wires as well? (they are the same ones that came with the imported engine
