Earlier this week, I got my Kleeman headers and Pulley installed. I got my EC tune yesterday.

As we all know with installing Kleeman headers, you lose your secondary (Post primary cat) 02 sensors. I saw the leftovers of my exhaust system and my secondary 02 sensors are totally unplugged.

I got my tune from EC and still have codes P0140, 141, 160 and 161(all associated with secondary 02 sensors unplugged). After talking with Adam at EC and consulting with Jerry, he said they couldnt get rid of those codes to clear the check engine light remotely and that I would have to get them coded out in STAR DAS.

Anyone got any info on where in STAR to do this?

you will have to have the rear O2 in th stream and then turned off.
they must be hooked up and in the exhaust stream.

From my understanding as I just talked to Jerry about this yesterday, they aren't exactly turned off but the reading is manipulated to not trigger the CEL. Jerry mentioned just like reverron did that they have to be plugged into the car. You cannot disconnect them physically.

Not sure why the rears weren't plugged in...they should be. Might want to try my trick. Buy some o2 bung extensions from Bruce ttm for the rears. Worked so far w me and have put 700 miles since my headers installed and no cel light.

Hmmm.. looks like I need to at least plug in the secondaries and try to code them out.

I will call Jerry on Monday to see what he has to say

I have the same problem and was told this was the solution as well.

How is the power difference? Worth it?

Kleeman Cats require you to fit a set back spacer to desensitize the post Cat O2 sensor if I understand correctly. If not please educate me.

skratch77

you can run no cats at all and have no codes thrown if you send the ecu to them,they code it for free if you buy there headers.

Glyn M Ruck

Yes - I understand that - Thanks!

"them, they, and [their]" being Kleemann, to clarify.

Can this be done with STAR as well?

Is it not possible to build an O2 simulator that will always give the computer the reading it wants to see? These were quite popular in the late muscle car crowd till the EPA got mad at a few of the companies making them. There are instructions on how to build them online if you look around. Just plugs in and tells the computer what it wants to see as the post cat O2's only tell it if the cats are doing their job. Just plugs in and you zip tie it to something, it does not need to go into the exhaust stream at all.

Yes that is what I have for my rear o2's. You can build your own for less than $20. Or buy them from a vendor.

Secondary O2 can be turned off and you can take them out with star diag, development data, control unit adaptation, variant coding, implizite codierung... item nb 183.

Fantastic! Thanks for the info!!!

I have a set of TTM's 90 degree extenders on the way. Not the same as a simulator but I'm hoping this will lower the amount of hydrocarbons the rear O2's see, essentially simulating the presence of a primary cat.

raleigh29

AWESOME info. Do the secondaries need to be plugged in to code this out or does it matter if they are totally unplugged?

saleen01

who sells these for our cars?

novae500

Bruce TTM motorsports!

Thanks for the info. Will ECM coding changes overwrite my EvoSport tune?

saleen01

just bought some, thanks Bruce!

i don't remember, you can try.

No.

You are welcome Bob.

Actually you should be thanking Minh(novae500) too!
