where do u get the 02 sim at? i could get everything else but where do u get the 02 sim.?

civicvtec1ps · 10-07-2003

you must start making more

SomeDoodToo · 10-07-2003

And i take it the ecu is in the same spot on the 7th gens? forgive me if u wrote that in their i just skimed

WannaBFast · 10-07-2003

yes, you have to remove the glove box first, the ecu doesnt sit flat like that, it sits vertical, yes i am working on getting more out.. i didnt expect them to sell so fast, so the red arrow connector is on the top, you splice in power from the bottom

Is 02 sim better than MIL elim? What's the diff? Anyone know?

WannaBFast · 10-07-2003

well im not sure how the mil eliminator gets hooked up, i believe it gets spliced into the oxygen sensor wire directly so it sits outside, mine stays in the ecu compartment

What kind of chip do you use to simulate o2 readings?

WannaBFast · 10-08-2003

im using the standard 555 timing chip

ok...this is a ghey question and has been stuck in my head ever since I saw this thread...wth is an 02 similator? I searched too.

WannaBFast · 10-08-2003

my o2 simulator is a circuit that sends the proper voltage to the ecu that simulates what the oxygen sensor would normally give, but if you have a test pipe, or different header, it will throw that signal off, and give you a check engine light, this just prevents the check engine light and makes the ecu think that your cat is working properly

how do we buy one and how much?

civic-king · 10-08-2003

i hope you didn't run out before you sent mine......

.....just kidding...

S2KREY · 10-08-2003

cant we make are own 02 like buy parts from radio shack?

went to heald for a while kinda know how to build cicuit boards

WannaBFast · 10-08-2003

yes you can, but the parts list comes up to around $20 anyways with all sorts of extra parts left over, and thats not including all the tools you have to buy
this way, you have no waste, and not have to spend 4 hours figuring out the circuit like i did...
