Mac Pro Chamber

[Mach1InFront]

I just received my pro chamber. I was told to order 2 sensor simulators.... But I realized there are 4 sensor holes. One guy told me keep the 2 in front and simulate the back 2. Another shop told me simulate all 4. The guys I talked to at RPM.com where I ordered them said 2 in front and simulate the back 2. Any input please. My Mach is my daily driver need to make sure I do it right if I am gonna do it at all. Kno what I mean? Thanks in advance

2 out of three said 2 sensors in the front and 2 simulators in the back. I would go with this 1st. If you have any lights come on then get the remaining 2 simulators. No biggy. :thumbs:

keep 2 infront and simulate the 2 in back :thumbs:

I was thinkin 2 outta 3 also but, I would like someone who knows, someone who has done it with no problem. Thanks for the input.

you also say, "If a light comes on add the other 2" is it really that easy? Is there any harm in not doing it right?

From what I understand, the check engine light would come on if there is something wrong. No real harm other than that light glaring at you all the time. some have even eliminated that light after exhaust mods.

wont it change the computer to abnormal running mode?? like loss of power? change is air -fuel, stuff like that?? maybe i am wrong

Yeap stimulate the back.

I have the MAC ProChamber h-pipe and I used Steeda's MIL Eliminators on the rear o2 sensors. I originally had Dallas Mustang MIL Eliminators, but that set failed to keep the SES out. Since the switch to Steeda's MIL's, the SES light has yet to come back. I've driven several thousand miles without any trouble.

Juts use the Seeda MIL's and you'll be OK.

Been driving mine for over 1500 miles, and no probs. And, +20HP, 18TQ on the Dynojet Dyno. Can't beat them.

Hey

I would try no sims. Then if everything is ok you can send them back. If not try the front then the back.

[Blazinsteed]

It won't be ok and if there is something wrong with the engine you won't know. Anyway all you need to do is keep the first two nearest the head and swap the back to for mil eliminators. The back two is what the front two compare to. You have to have the first two because it reads exhaust gases coming out of the header and helps to regulate the fuel/air ratio while the back two just measure the exhaust gasses coming out of the exhaust to make sure they are legal.

What he said :beer:

[Mach1InFront]

thanks guys I appreciate it. I am gonna do it today probley. Will let you know how it turns out.

[Mach1InFront]

I never got to do it today. Very busy. I also have one more question.....whats the deal with the MIL's? It says cut the tabs on the passenger side so they fit???? I am not too familiar with this. Can anyone explain to me what they did or had to do to get them to work?? Thanks in advance

[Blazinsteed]

Ok there are little tabs on the male end that click into the female end on the outside of the mi'ls. I had to take a sharp knife and cut the tabs for it to stay in place. Just make sure you tape it up afterward with electrical tape to keep rain and so forth out of it.

OK I have been sick for the past few days, I hope that is why I feel like a Dumba$$, but.....cut the male end of the O2 sensor? or the MIL's? Then the O2 sensor plugs into the Mil, then the Mil goes into the X pipe? And thats on both sides? Just wanna make sure.

[Blazinsteed]

You will have a male and female end of each mil .... One to plug into each sensor. Cut the clippies of each male end.
