Does the PA flash remove the secondary o2 reading?

yes it does, I don't even have an 02 sensor plugged in and I have no CEL. And I can still get CEL's, it isn't like it removed the capability of a CEL. Make sure you tell arvin this, as I think it is a 'custom' feature, I don't think all PA's do this.

i would agree

Cool thanks. Ill get to ordering.

hey everyone, thought id post this in an existing thread since i couldnt find anything related to what i got going on, anyways

the other day after work i started up the car and got a CEL. i had a friend scan it for me, and it was for the primary cat being removed. the thing is i already have the CEL delete programed in my tune from Arvin. i reset the ecu (neg terminal off the batt for a while) and then flashed the same tune again. it worked for maybe a day or so then came back on this morning.
i also tried flashing to the other tune i have loaded on my PA module. the CEL back on after a min or two of driving. i already contacted Arvin and told him what was going on. waiting on a reply back later on today.

just wondering if anyone else has had this happen? i havnt heard of it before so i could be the first.

technically, it doesn't remove it. It just changes the parameters that it requires to cause a cel.

When tuning any ECU, you can't "delete" fields, you can only change the values.

this is true, but the problem still stand that the CEL is showing up when is shouldnt. my ecu is being stubborn. ha

the PA augmented o2 parameters and a spark plug antifouler on the sensors should stop it from throwing the cel. unless its some other o2 cel error.

ill try and pull the code later on today and make sure its the right one, or some different O2 code.

nope, sorry man, haven't had any cat related CELs as of yet with 10k+ miles on it.

crisis averted, Arvin hooked me up fat!! Arvin's the man.

yup! i told br to turn off both...

I dont see why you wouldnt be able to turn it off, every ECU ive tuned has the option to do so.

I've seen 2 or 3 o2 cels.

one for the heater (o2 sensors have heaters in them)
one for it not being connected (which it was)
one for stating that the cat wasn't working.

last 2 kinda go together.

Yeah i tried just the defouler trick and my CEL light still came on, I'll have to wait on the PA module.

pull the code,

could be that the sensor is not seeing enough exhaust, seen it happen with mine.

thanks I'll do that! guess if it's that i might try drilling the hole one size up.
