so its not a true eg6. so wat but its a 93 si hatchback, with a b16 swap, and im trying to put an air fuel ratio guage in it but i dont think its working right because its always banked on lean, and at idle theres not even any lights at all... so it anyone knows how to hook it up correctly please help! thankkss

 

i just put an autometer air/fuel gauge on my 93 DX. when im cruising around 3000 rpm the lights on it scroll from left to right continuously but when i mash the throttle to wot only the green lights are on (which means im running a little rich)....if i let off the throttle completely and at idle there usually are no lights on or just one or two red ones....

 

where did you connect your wires to?

 

i connected the green wire that came with the gauge and put it to the white wire on the 02

 

mine has a purple wire....i connected it to D14 which is white...the third plug from left side of ecu...its the 2nd largest plug....

 

your supposed to run it off of the second oxygen sensor.

 

are either the cars boosted if not they are pointless i had on in my ride and it just bounced around worthless *** light show

 

mine was laying around in my closet so i installed it along with a oil pressure gauge i also had......and i know a narrow band isnt very accurate but its better than nothing

 

im running a 98 B18B in a 93 DX hatch n/a.......i only have one O2 sensor....ive read that its better/more accurate to connect at the ecu then at the sensor....plus you dont have a stray wire in the engine bay

 

AFR guages in any car is pointless. You put a wideband in to tune a car and then take it back out when the tuning is done. No need to keep it around unless you're hard parking it.

AFR's just don't change by themselves.
