ok, i'm about to buy a defi boost and air fuel gauge. i just need to know if i need to buy the defi link to go along with it? if not what do i need, if anything.

 

defi bf needs the link , defi d doesnt
a/f gauge needs the bung welded to the downpipe

 

which series do you want to buy? if BF then yes

 

no the d-guage

 

whats the bung?

 

a little metal piece that has threads in which the a/f sensor can be screwed into. kinda the same as cel sensor just after the cat, just bigger

 

i thought that you just hook the sensor wire up to the front o2 sensor on the ecu???

 

u should b able to tell when u get it if u need a bung welded into the downpipe or not i would assume so and u dont need a control unit for the d Series..

 

so i dont need to weld it to the downpipe?

 

the sensor is the one that needs to be installed on the downpipe

AEM UEGO Wideband 02 Gauge

Product Description

AEM’s Wideband UEGO Controller is also available in a gauge that includes a single-channel analog output with a Bosch O2 sensor in one unit! AEM’s Gauge-Type Wideband UEGO Controller features an LED readout and sweeping LED “needle” that changes colors as AFR changes from rich to lean. The unit’s 52mm (2-1/16”) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere. No laptop required for monitoring!

Key Features:
-Bosch sensor included
-24 Color-coded LED display lights provide immediate reference to engine’s air/fuel ratio (AFR) or Lambda
Integrated three-digit display reveals AFR or Lambda in real time
User-programmable 0-5v analog output included for use with data loggers and ANY engine management system
Ideal AFR monitoring tool for carbureted applications and engine dynamometers
Does not oscillate AFR like narrow band sensors
Serial data stream included for output of AFR (RS 232)
Accurate to 0.1 AFR

i will post up some pics tomorrow of the gauge

 

unless i am lying^^^

btw , yes you still need to get it welded

anything else bro?

 

so you are saying that i need the wideband in order to install the d-gauge a/f

 

it comes with one. thats why the gauge is so damn expensive

 

i just got mine today and all that i got was the power wires and the pink sensor wire. no bung. it was only $112 not $400+

 

but you can get a gauge that hooks up to your ecu , but is not that accurate

i am just against the cheap, all show, gauge
