Wanted to make sure everything was mechanically sound before I start the tuning process. EST error code popped up. Runs alright, can start a little hard, but it runs fine. EST I would imagine would make it run like straight crap considering it controls timing adv./curve.

Also, I'm not sure what the spec on these O2 sensors are, and wouldn't be able to find out until the weekend when I can get on all data or mitchell. Based on temperature, is this what it should be reading?

It will still run with an EST error the module will have some rudimentary control of timing. That is definitely a big problem though, You need to fix it before proceeding with any tuning.

 

Alright, I will find if I have a bad wiring issue or if the EST is bad and will replace it when I get the chance. However, did you have any idea if the other readings were correct for temperature?

 

Everything else looks pretty normal
