02 simulator help
So i've had my B&B midpipe installed for sometime now. Accompanying my B&B catback. You'll definately hear me if you ever pass me on the street lets just put it at that. I've had the check engine light on for sometime too since i've been too lazy to take care of it. Now that i want to get my ECU reflashed from Mazda and get some other recalls done. Also get my first oil change i'd figure i would get rid of the CEL first.
What can i buy to get rid of my Check engine light because of a midpipe? I did my search and came up with the Casper electronics 02 simulator but the picture they have seemed to have changed from a while ago. So is part# 104052 the same 02 simulator i want to get? Could someone help me verify it thanks. Since now it doesn't have the plugs its just a wire in. heres the link if you want to check it out Casper |
I'm not sure this is the one you want to get.
This part seems to replace the front 02 that must generate a cross-count signal to the PCM. |
Actually, that would be the proper part for the rear O2 sensor, but it isn't likely to work. I hvae one sitting on my bench and I never used it because I didn't need it.
The rear O2 sensor on the RX-8 doesn't cycle like the rear O2 sensor on OBD-II cars from the past. That sensor is just there to verify the function of the CAT. That said, I have the BB midpipe as well and no CEL. If you installed the O2 sensor back in the bung and you are still getting the light, you could try a hard reset of the PCM. Failing that, you will need to construct a circuit that will reduce the output voltage of the OEM O2 sensor by .2v or so to simulate the presence of the CAT. |
But will it generate a square pattern that goes OVER the centerline?
I'm not sure if this is the signal the PCM is gonna be looking for in the rear CAT |
how do you reset the PCM???
|
So is there a way at all to get rid of the CEL? A few people came forward saying the casper electronics was the way to go to get rid of the CEL. An more opinions anyone?
|
|
I have the casper unit with my Midpipe and have never gotten a cell. Wiring the thing takes some patients but it works. I will try and post a schematic for you all so you don't have to spend as much time on the thing as I did.
|
Is there any someone with a scanner can capture the pattern of this O2 sim?
I have installed some headers on a Mz6 and the CEL eliminators keep setting a code. |

I find it hard to believe your cars CEL light is not being triggered by the testpipe. The sole purpose of the second 02 sensor is to verify the presents and efficiency of the catalytic converter. If the catalytic converter is present, a cell will be triggered. |

The sole purpose of the second 02 sensor is to verify the presents and efficiency of the catalytic converter. If the catalytic converter is present, a cell will be triggered. I'll say it again for clarity: The rear O2 sensor on the RX-8 is a narrowband sensor that does not cycle (for tuning purposes) like a traditional O2 sensor on other cars. It simply provides a "range" measurement for use of the PCM to determine the A/F after the CAT. This is done to simply determine the efficiency of the CAT itself. A "traditional" O2 spoofer typically shouldn't work because its signal looks nothing like what the RX-8 PCM is expecting. That said I don't have a CEL regardless of what you believe. |
Originally posted by MazdaManiac That said, I have the BB midpipe as well and no CEL. I suggest you go dealer and get your car checked out. The CEL illumination bulb may be damaged in your car. Or you can buy an ODBII scanner and see it for your self. |
Originally posted by RX8on19s You stated that you have a testpipe and your CEL has not come on. That is total BS......One of the roles of the O2 sensor is to check it the CAT is there. Therefore, if the CAT is not there, a CEL will be triggered. I suggest you go dealer and get your car checked out. The CEL illumination bulb may be damaged in your car. Or you can buy an ODBII scanner and see it for your self. Obviously I have a CAN/OBD-II scanner, look for my posts on ths subject. Obviously, I know what I am talking about, look for my posts on the subject(s). Of course my MIL/CEL light is functional, I've used it before. It comes on every time I turn the key to "ON" without starting the car. Once again, look for my posts on the subject. What would you like, pictures? My test pipe has been in the car since April 2nd with no CEL on the "L" flash. Get a grip. |

Don't change the subject buddy. This issue is that your statement is not true when you said that your CEL did not come on when your took off your CAT. I will stop beating this dead horse.
Oh, I almost forgot. Just because you have tools, does not mean you know how to use them. |
As you can see from the second graph, the OEM rear O2 sensor doesn't have the rhythmic pulse that a typical feedback system has. That is because there is no tuning going on from the rear O2S.
As you can also see, my rear A/Fs are pretty much stoich to lean as far as the rear O2S is concerned and that is why I get no CEL. Ever heard of the Greddy E-Manage? |

What graph are you talking about? You forgot to post it…
Yes, I know what an e-Manage is. I would not use one because I have yet to see one produce more power that my RIC SHAW piggyback. |
I did not recall calling you a liar, so do not put words in my mouth. I said your statement was not true. Being a liar and saying something false are two different things. You probably just don't know any better.

My comments are based on experience, not on a little graph. I know your statement is false. End of story…

Not the end of story.

Originally posted by RX8on19s You stated that you have a testpipe and your CEL has not come on. That is total BS...... Maybe this video will help you: REAL MEDIA Installation of the midpipe is here: BB Mid Pipe INSTALLED You are falling prey to a common error in logic - non-representative sample. You believe that just because you have not observed a situation youself that it is not possible. That is akin to covering your own eyes and believing you are now invisible. You have also, more or less, done the same thing with the Ric Shaw comparison. You can't make an intelligent decision if you refuse to look at the data. You can admit you are wrong now, or I can go on... OK. I'll go on. Here is the flash page of the OBD-II scan. As you can see, it has been 15 starts and 295 miles since my last reset and there are zero stored codes. As you can also see (peek through those fingers now) that as far as the PCM is concerned, the CAT is happy too. Even though it is propped up on the wall next to the car.:p |

Cucumber,
We obviously see this topic differently and we are not going anywhere. Let do something constructive and beneficial to this forum. Let’s open thread and get feedback from other owners that have installed midpipes. Let see what they have to say. I have helped install several midpipes on RX-8’s and have yet to see one not trigger a CEL without the simulator. |

No doubt you have triggered plenty of CELs. |
Come on guys...there are enough idiots here to argue with, two smart guys arguing is a waste of time.
Thank you Maniac for the scans. I know the effiency of the CAT is judged by the difference in the front and rear 2 readings. I just want to make sure the rear signal still fluxuates to avoid a P0138/138 code. BTW in your "CANSCAN" Post I see you have an option for the mode 6 info. Can you see the CAL level? |

Thank you.

You both need to cool it. This argument about whether or not somebody called somebody else a liar is childish and silly.

If his car has no rear O2 sensor yet still has no CEL, only he will know it. You can't accuse someone of anything unless you have proof. Maybe his car has a problem, ever think of that? Maybe it doesn't. If it didn't throw a code on his car, it doesn't necessarily mean it won't on another car. There are also people on here that say the O2 simulator did work on their cars and others say theu didn't. Who's wrong now? MM is one of the most honest guys on here and he really knows what he is doing. If he says it, it is true on HIS car. Each car is a little different. What should happen isn't what always does happen.
|
Just to add some clarification:
I DO have the rear O2 sensor, just no CEL. |

Mazdamaniac's rep speaks for itself as does his skill. The question should be 'how do I get my car to do that?' Perhaps there is something to do with the emanage install he's done?
|
Originally posted by Sanguine_Dark Perhaps there is something to do with the emanage install he's done? I'm afraid that RX8on19s didn't quite absorb that fact, though. He has a problem with facts... |
Does this mean I learned something? :D Just curious MM. Is this caused (or lack thereof) because the o2 signal is going into your emanage instead of ecu thus no CEL? Also...does your canscan thingymabobber (technical term) read from eman or just ecu?

The CanScan thing-a-ma-jig only reads the PCM, but that is enough. The E-Manage does a pretty good job of logging itself. |
easy guys
wow I can't get over how the posters on this board can *uck with people the way they do.
MM I think your honest we talked about this when I installed my B&B pipe with resonator and I put on a sim and got the cel. I still have it but don't worry about it after finding out it did NOT effect the tune. I was gonna try the casper but have decided to save my money. Still again in several posts I made I have been slammed like you just were and I don't like it. everyone has an opinion but this forum is supposed to help not slam people. even when a guy who lists himself as a senior member asked how to get his rotors off to paint them (rusty on delivery) then asked four or five more questions about them he was not slammed like this(and maybe a senior member should have some really simple basic car skills or at the least not admit it). Jeff thanks for your sharing and keep it up.......!!!!!!!! and the rest of you talk nice or get f off the board Stras |
