I was wondering if there is any interest in building an o2 simulator, so there's no need for the 2nd o2 sensor in obd2 vehicles, getting rid of the check engine lights...

i am going to built a few, tweak them, and see how well they work, any beta tester's? I'll build say 5 of them and mail them to you for free, and all the tester has to do is post their opinion(s). Those with factory ecu, o2 sensor problems(CEL), or those with o2 removed only please, obviously.

Those interested post email.

(This is also posted in the FI section, mods hope you don't mind, i am doing this because i will be removing 2nd o2 sensor for turbo and don't want cel)
