after reading an article in EuroTuner about how much they stand behind this gauge, i decided to get 1 for a mier $199
extra bung, AFR 02 sensor and gauge, custom harness, Innovate Motor Sports program on a CD to install it to your laptop, special wire and connector (the funny lookin 1 with the 2 fastenign screws on the side) to connect to your lap top, and 2 option on bezzle right and face plates for the gauge.
quit alot of stuff for that price imo.
i was surprised.
on with pics.
extra bung welding in.
i had a local shop, D&D Muffler, cut the whole. i welding it in at home.
now dont just go and put the extra bung anywhere, or directly across from the exsiting bung just because mine is.
however, it is crucial to have it aligned with the exsiting o2 sensor as this will give your gauge an exact reading of what the ECU is seeing.
you need to mount the whole thing to see exactly where you will have room for another AFR o2 sensor.
once you have found this spot, mark it and make a hole.
do not do what the dumb ass, who i bought it from, did here.
and dildo baggins sold this to me as a good usable setup.
see how he's got the 2 next to eachother almost inline.
now this means your not gonna get the same reading as the ECU.
either because the ECUs o2 sensor doesnt have full flow over it OR the gauge's o2 sensor doesnt have full flow. depending on which sensor is where.
not only will it not be accurate, the placement of the second bung is too close to the heat shield and therefor i couldnt mount it with a o2 sensor in it.
ps: the cap on the 1st bung was a temporary thing. it is now on the second hole.
so i got in there with a file and bored it out a bit. took only about 10 mins or so.
and i used the gromet that in there too. it was a tight fit to get the connector through it, but it works.
i wired up the gauge too.
for the power i used 1 of those 2-in-1 fuse holders.
2 10A mini fuses, and plugged it into the head light slot on the fuse box.
and ground it just about anywhere except for "noisy" grounds (audio, ignition).
and tada. haha.
the gauge come with start up/calibration instructions, but just for the sake of this being a DIY.
so once the power and ground are connected. turn the ignition to the ON position WITHOUT the sensor connected.
keep it on for a minimum of 30 secs. turn the car off.
the connect the o2 sensor but DONOT plug the sensor into the exhaust. it needs to be callibrated in clean air.
turn the key to the ON position again, it will warm up in about 40-60 secs. depending on how cold it is.
when it is done the gauge will read max AFR, 22.4
now if you did all of the above, but didnot run the wire through the fire wall. you can disconnect the wire and o2 sensor. but DONOT turn the car on or you will have to re-calibrate the gauge.
so after all this plug in the o2 sensor into the exhaust and your good to go.
