how do you shut off the CE light with offroad exhaust?

[screamin gt]

just got the engine all together and it runs perfect except the check engine light came on, I assume due to not having any cats on the exhaust. how do I fix this problem.

also, the guy that I bought the car from said he already had something installed to fix that problem, and it wasn't on before I rebuilt the motor due to spun bearings.

it runs perfect so I assume this is what it is, but I havent had it checked yet.

get your self a programer like diablo or sct and it will take care of that problem and your t/c problem

Or MILs.

Or MILs.

MILs are a much cheaper option if you don't have the cash for a tuner. I've been running mines for almost 6 years with no problems.

i installed mils, and 2 weeks later the cel came back on so it just stays that way

if you dont have a lot of mods, get the mils. if you have a good amount of mods....then it could be worth it to go with a tune.

if your runnin a catted offroad exhaust system , mils wont work cause the cats are still adding higher temps, then when you add the mils it puts the voltage signal too low. so hope that helps and good luck. oh and ive been runnin mine for almost a year but i have a o/r x and no cats.

Catted O/R??? doesnt O/R (offroad) mean NO cats... who makes a catted O/R?

I just sold my catted off-road exhaust system for a supercharged turbo system.

 

[screamin gt]

no cats.... and what is MILs? that is what the guy I bought the car from said he had. how can I check?

while they were off I had the heads ported /polished/valve job. could that be why w/e the other guy did is not keeping the cel off now?

 

[screamin gt]

and as far as the tune goes, I assume that is basically what a power commander is on a fi sportbike? like basically downloads a new map to the computer?

sorry but I know more about bikes than cars

MIL's or MIL Eliminators are a small plug that plugs in between your o2 sensors located after the cat. Non-catted pipes set off the O2 sensors and you get a "check engine light" within hours of operation. If you look under the car, you will see O2 sensors way up near the exhaust manifold. You will also see 2 more located near the catalytic converter (or where the cats used to be). Thats where the MIL's will be located. Heres a pic

[showstopper2]

best way to eliminate them is have the rear 02 sensors shut off in your tune..

well 03redstang, no o/r doesnt mean catless. bassani, bbk, pypes, etc. they give the option for vehicles requir them in certain states. i have the bassani o/r catted x-pipe but i cut them off and welded a peice of 2.5in pipe instead

If Bassani offers an off-road catted pipe, please enlighten us all as to what the difference is between off road catted, and off road non-catted. We are all anxious to know. I know I am
