1GR-FE rebuild

Thank you rheath08.

 

I noticed you got those nice headers, no cats I assume? How do you control the engine light? I have heard folks use a URD O2 calibrator, cuz I was interested in replacing my beat up manifolds and thought the URD headers were pretty nice looking. However, I reached out to URD, but according to them they never had such a made nor sold the devise even know its on their website, go figure. I always wondered how folks get around that.

 

I have 02 sensor simulators. They are no longer manufactured. I hear there is a way with HP tuners, that may be something to look into.

 

Yes you can disable the CEL for the secondary O2 with a tuner. I've seen people have good success with "mini cats" or O2 sensor extensions as well.
