How TO: CEL/MIL Eliminator!

with my mp5 being turboed is it better to just leave the CEL alone seeing how the car tends to run richer this way or will it be better to put in the CEL/MIL eliminator. id rather it run rich then lean

Yeah..but if you live in a state like NJ..they will connect to your ODB II and scan it for any codes..and if the cel is on..you will immediatley fail!

Chas! I got a question. Is my milage suppose to suck 1st few days after header install and CEL Fix? Will it ever go up again? I mean, before header was installed, i was doing 212 miles on a HALF of tank. Now I got 180 miles on half of tank. We're talking about SEVERE drop in milage. s***, I hope its not gonna be like this all the time! Any input?

Mileage will def suck after you reset the ecu. It causes the computer to relearn maps..So basically it runs richer for first couple hundred miles..than computer leans out the mixture.

How you drive the car will defenitley determine your gas mileage. If you like to stay above 3k rpms..than expect the mileage to plumit fast.

But if you are nice..and shift before 3k You will get better #'s.

Edit: Ok just checked the NASIOC board and found some relevant information. The O2 sensor voltage output is directly proportional to the temperature of the filament. By using the anti foulers you effectively remove the filament from the hot exhaust gas flow lowering the filament temperature. When the temperature is reduced the voltage output of the O2 sensor is reduced, simulating the output of the O2 sensor in the exhaust path, with the cat installed.

Here's a link to the thread:

You sir are my HERO!!! Ive been stressing soooo badly about this as my Circuit sports J-pipe is in the mail and I didnt have an O2 "helper"

The scooby guys have the perfect solution - $5 no jibber jabbin with the wiring - nothing that isnt removable - ill be doing this mod when I install my pipe this week - ill let you all know how it works out k?


FAAAAAAAAAAANNNNNNTASTIC!! I can wait for this!!!!! (read over the 9 or more pages - there are guys with over 3000 miles - one with over 6K miles and still CEL free!!!)
 
I did the spark plug non-fouler fix for 3.97 and no CEL yet. I have 200+ miles on it. Without it the CEL came on in like 20 miles.
 
How To Install Mil Eliminator Kit?

I have been reading a lot about the MIL eliminator kit and I have found one on jegs.com, but I am still unsure how you install this part. Would anyone be able to help me out?

which part are u talking about?
 
dude...
i thought i read somewhere that u can but a MIL eliminator already assembled....i think it was Apex'i....can anyone confirm this
 
The CEL won't go away, you will need to reset your ECU to clear it. Just disconnect the battery and wait, I think 30 seconds ?

I have about 400km on my car since I installed the mechanical fix and no CEL.
 
Update:

Ive had the mechanical for over 1200 miles now . . .

Not one problem! I have all sorts of driving on it too, city, freeway. In rain , dry, hold, cold and even snow.

Looks to be the best $2.99 ive ever spent!
 
OK no one ever gives me a clear respone on here. HOW DOES IT WORK WHAT ARE THE PHYSICS? Does the trick take a 1v signal and make it .5v? or What? Also do you have to have an actual oxygen sensor for this to work. Lets say my rear o2 sensor is completely gone, can i hook the rear o2 wires up to the front 02 with this mod in line? Also on a 3rd gen what wire are what, blue is signal return. black are heater? white is signal source?
 
You need to wire it with a O2 sensor. It modifies the voltage to be within spec. There is a mechanical fix also. That's what I did. It cost $4 and NO CUTTING!
 
The mechnical fix works perfect so far! I've got atleast 1500km since I did it and it works great! (cool)
 
i have followed this thread to a t and never got it to work, (i am an electrictian on planes and solder all the time) but after 100 miles or so i pop a cell and when i have it read it is for the 2nd o2 sensor... i have been just living with it and dont get worried until my cell starts to flash...... i will take a pic of how mine is setup later to see if anybody can tell me what i did wrong....
