Ok Im starting to get the idea that there is a serious issue with or 2005 Evo's, and the Perrin O2 simulator that is allegedly supposed to work?? Just from talking to the tech guy at Perrin and some other 2005 Evo owners the same basic problem seems to be the P0137 code after a cat delete is installed. It doesnt even seem to matter that the perrin O2 sensor fix is installed, the damn cars are still throwing the P0137 code. So my question is has anyone found a fix, or is this something that Im going to have to live with, or is there a fix out there???

 

I have a 05 and I use the anti-foulers when I use the test pipe and had no cel for 7000 miles.

 

forget the sim

I have the fix on my safc so I don't throw a code with my test pipe.

 

all you do is goto a exhaust shop, stick a pipe about 3 inches onto your exhaust, weld it, stick your 02 sensor onto the hole, problem fixed.

as long as the 02 sensor is warmed up, you wont have any problem.

I've posted on your other thread, with graphs and everything. lol

 

Elaborate......how did you tune it out with your SAFC??

 

look in the how to section for mechanical 02 sim, you can make it for $5 and i haven't had a code for 26,000 miles.

 

Amazing! Can you fix the P0300 misfire code too with your SAFC? Mitsu could start sending all the 2003 Evos with misfire codes to you and you can retire.

 

use the cel eliminator from vishnu it works great with my car! no cel yet!!

 

I drive an 05 Evo and this was my choice, no CEL in the last 2000 miles.

I've been using the Perrin 02 sim on my '05 evo for over 2,000 miles. No cel. I will see how it continues to work when I break the car out of the garage in the spring. If it happens, I will put the stock catalytic converter in for my OBD2 state inspection.


Makes me wonder if people have been having some install issues...wouldn't be the first time on this board. -Gabe

 

SIMS are a waste of money on the EVO. I used the 5 dollar DIY Spark plug defouler method. No CEL, 6K miles so far.

I never had a cel on mines.

 

i personnaly have the perrin o2 sim as well, had it for 5k miles and still no cel....maybe i'm just lucky!!!

 

i have the ultimate racing tp for about 7500 miles, and no cel!!!
