o2 sensors and simulators

[RevLimitLaunch]

alright gettin ready to do a custom catless downpipe on the ms6, lookin to see how many o2 sensors there are and if anyone has a recomended place to get some simulators for them ((fu) to cel's) thanks

2 o2 sensors one before the cat and one after....not aware of any ghost o2s....

Just put a diode on the 2nd O2 sensor, piece of cake and costs $1.99.

Works wonders on mine.

nice and thanks. this seems like the easiest least $$$ project. are the wire colors the same for the ms6 tho?




also i've found this tech on spark plug foulers being used..just wondering what anyone thinks of them

I didn't get pictures but when I had my exhaust done there was only one before the cat. I didn't have one after my cat, I almost removed it but decided against it.

Nope, use the diode, same color wire.

oh ok, and you only needed to do it on the 2nd o2 sensor? works for me i guess. thanks alot, great help!

alright so one other question, what is the thread size on the o2 sensors? lookin for bungs lol.

Only 2nd O2 sensor, DO NOT TOUCH the 1st O2!!!!
I have no idea what size the threads are but email info@atpturbo.com and they can sell you the right sized bungs.

i guess i should've edited my post earlier, found out its m18x1.5 which i guess is pretty universal to almost all cars.

Do I only need to put the diode on the black cable or a diode in each cable.

My sensor have 4 cables 2 whites 1 black and 1 grey.

I understand i have to put the diode only in the black cable, is that correct?

TIA

i'd use a spark plug fouler type trick if i were you, check ebay, its an m18x1.5 like other cars. just search 'o2 simulator' and pages upon pages will come up.

mazda will extremely frown upon seeing a hacked up o2 wire lol. i do believe it is that wire though, but i'd wait to find out for sure.

Black= Signal wire, White wires= heater, Grey= Ground.

Connect the diode to the Black wire, with the white stripe on the diode facing AWAY from the sensor.

You can also get a non-fouler kit at the autoparts store. Just drill out the last half to fit the o2 sensor.

Hi!

Just to let you know that I did the diode trick on the black wire, and with the ATP 3071R turbo kit and of course the ATP DP do not have a cat.

I have no CEL's.

I am happy!
