ive got a megan high flow cat right now and was looking for an o2 sim, i searched and found that a lot of people have been using the casper electronics one. its says plug and play...well, i may be a dumbass but what does it plug in to? i dont know much about oxygen sensors and o2 sims but from what i could understand about most of them was that they wired into the o2 sensor...but hey i could be wrong. also would the casper one work for ex's? im sure it would but it wouldnt hurt to ask.

i just installed it... it connects to the plug of the o2 sensor and then to the plug of the car. Very easy install. plug and play.

i have replaced the cat with the free flowing header obx for dx/lx model, so the cat is cut so i ordered that 02 sim fom casperelectronics, and my engine light never came on and everyone said it would..... do i need to install it or can i continue to go without it, both sensors are connected but no o2 sim and no light from computer..

My CEL didn't come on for a couple days after I installed my header. Yours will probably come on eventually.

I have a high flow cat and my check engine goes on and off every 100 miles or so..... Does this really work?

Yeah, the casper sim is great...I haven't had a problem with it since I installed it 1 year ago.

Just get a MIL eliminator, costs $15.00 from bigjoshracing.com. Installed it with my kamikazi header last year and CEL has never come on.

ok guys I just hit 215 miles without any check engine lite....
I have a high flow cat header.... It might come back on but cycles on and off
Normal is about 50 to 100 miles it will change....
Maybe the weather here....
I have had the cat + header for about 90 days or so....

Well I was going to go buy one caue i hated haveing the cel on sometimes.....
it would cycle on and off every 100 miles or so but now i got like 400 miles on it and no cel. I think its the weather!

Rep Power: 0

the same thing was happening to me the cooler the weather the light would go off. but the car also felt like it had no power most of the time. im glad i got my mileliminator. car runs much better

did you try cleaning the sensor with carb cleaner before you put it back on? it might help.

 
Rep Power: 0

So the other day i hit about 400 miles and the cel came on
But very weird turned of in less than 10 miles?
Weird .........

would it make me pass inspection? i think the one from bigjosh sucks..i had it and it didnt work..im might just try the casper..u think it would turn it off?

I have had the Casper for a long time and I love it. The easiest and nothing like that crap BJR sells...but you won't pass emissions if you have no cat, reguardless, as the inspector (if hes not too much a ****) to hold the probe about 4in or so from your exhaust pipe, then you'll pass, I did. lol.

na cuz in new jersey i think he plugs sumthing up to your ecu and see..but u think the casper thing would help me..like let it read right?

 
Rep Power: 0

It will remove the CEL the ECU throws up so that part won't fail.

well its just a way to bypass the catalytic converter's o2 sensor... most all o2 sims require you to have the o2 sensor physically plugged into the exhaust pipe due to a heater control unit on the o2 sensor that no one has been ambitious enuff to come up with something to bypass it yet
