Hi again, hehe

I need to know, what solution do you people have for the "check engine light" when you remove the CAT of your car. Also , the performace of the car is affected by having the "check engine" on??, i dont know if its me or what, but I feel the car different when the stupid light turn on, also i think is sounds different.

Ok, evo guys , honda guys, and everyone use what I use and for everyone it works, but not for me, why?

ok what I use is this:


I mean the parts, those are "non fouler spark plugs adapter" of something like that, I buy form a autopart, and do what every one do, and I got the stupid light

What can I do? what do you do?

And Yes I know my english sucks very very bad, I hope you understand at least 3 or 4 words, hehehe

 

what you need is a O2 simulator

 

here you go bro this is a perrin O2 simulator with this you can even eliminate the cat and the secondary O2 and it will cheat the ecu into thinking the O2 reading is constant and therefore no CEL light

O2simulator

 

i use 3 of those on mine (it is quite close to the floor-pan)
on another car i used 2 and what i did for that one is to take a small asbestos stone and seldom block the flow to the sensor... for me both work

 

I imagine that's close. 2 is already pretty tight. I think I may add another antifouler, too. Lately the fix hasn't been working as well.

 

the question egk asks is kinda concerning since running on too much with a cel will make any irreversible damages(depending on the code it throws i guess). Dan posted that running lean too long is bad and w/e....but fooling the ECU with these sensors will make it work as if nothing is wrong or it just takes the cel off..

ill probably get a reply saying that if cel is off nothing is wrong but the mods are still there....i think i dunno how to make this question properly

 

Nothing will happen to the ECU nor the engine if AFR are better than 14,7

 

i would say the easiest/cheapest way, since I believe a wideband is a requirement for modding so you should already have one, is to emulate the second sensors signal with one of your analog outputs. if you do this, you will most likely still see a CEL if your AFR goes awry because you are still using signals from your wideband o2 sensor if the o2 sensor goes out: CEL! if the o2 sensor reads f'ed up AFR's: CEL!

 

oh, btw, please only run catless on the track. that is all I will say, no need for my regular argument

 

+20 on keeping the CAT!

 

plant a tree



the only recurring code, because of my mods, are system too rich and coolant temp below avg
but as far as a dtc for the 02 fix, no not in 2 years...

 

Pr_mivec this system too rich code...does it changes the performance at all?

 

My solution is not to use condoms, latex is a messy polymer ,,,,, engineers should invent a reusable condom just like a K&N filter that comes with a cleaning kit , how cool will it look to have a CF condom hehehe ... carbontrix help here !!!!......

 

Hahahaha! Now Migue's into the sauce tonight!!!
