hello to ls1tech fam. i want to know is it possible to get a good, stand alone tune for lsx swaps, that are code free? if so who can make this a reality? i drove my base tune for a while(with codes) and decided to try a drive tune. the vehicle runs great but still throws codes such as o2 sensor codes, bank 1 & 2, and emission, purge evaporator codes. if the pcm is sending , that means there is a prob. rite? i have to look at my scanner to tell u the exact codes. any help is greatly apprecieated. keep wrenchin ls1tec fam.

not quite sure what you are asking?

are you looking for a way to run the engine off a computer without having codes?

or are you looking for a way to turn those codes 'off' so to speak through a tune?

purge/evap/rear o2s/random emission codes are most likely due to you not having emissions related systems on your swap in which case a mail order tuner like Frost can disable those codes from appearing, while still being able to read useful codes that can help you diagnose issues in the future.

some more info on your swap and a more detailed description of your ideal system would be helpful.

are you still using lsx sensors? are you running o2 sensors at all...info like that would help

thanks for responding birdmaro. i want to delete all systems from pcm that r not needed to run in a lsx stand alone process . if the pcm sends a code, i want to diagnose it, solve it, and be back running. i also dont want to try diagnose something thats not suppose to be there.

as i stated earlier. my pcm is throwing codes(listed below). like i said b4, ineed some input to solve this delimna. i dont want to damage my engine.
