CEL after OFH+OFT
 

Around 1 and a half months ago i put my OFH on the car... flash it to stg 2 and was all good. Today after some road driving im getting my first CEL ever.
How can i fix this? read the code?
Currently im in Brazil, where this car isnt imported officially, and the nearest car dealer authorize to work in the car is 1200km away. Big problem...

Any help would be appreciated

Use your OFT and read the code. No one can help you if we don't know what the code is.

how do i read the code? just connect and hit read?

Don't remember off the top of my head. Just connect it and go through the menu options. Should be pretty obvious.

When i go to diagnostics, my gt86, ECU fault codes, it throws code P0420, wich seems to be for something related to my cat... Which i dont have... Since i have OFH. So should i just tell it to clear the code? Or reflash stg 2 again?

You more than likely have an exhaust leak if you are getting that code with a stage 2 flash.

I agree with @Malt, had one on my car the first time I installed my header.

Did you use new gaskets?

Any which way, it's probably best to check your header bolts after 2-3 heat cycles as they loosen up a bit. Also, don't forget to check that the o2 sensors are tight.

Got it. I uses new gaskets provided with the OFH. After install i never reajusted the bolts, so that might be the problem. Ill take it to the mechanic tomorrow morning.
After tightning everything should the code just go away? Or do i need to clear the code with OFT?

Just clear the code and you should be fine.

Hi,
You will just need to disable that particular code in Rom Raider. I think a few Stage 2 rom files slipped through the cracks with it still enabled. If you email me (shiv@vishnutuning.com) your CAL ID, I can do it for you.

Shiv, whats the CAL ID, and how can i find it? (noob here). So i shouldnt take it to the mechanic to tight everything up? or should i just in case?

pressing the info button under my car should show you calid

Vish, just sent you CAL ID, let me know if you got it. Thanks!

Currently in Hawaii with the wifey. And away from a laptop. But I'll be back home tomorrow and can update the stg2 file for you :)
