this is my question i have a 2000 camaro z28 and just put headers on it and have yet to tune the ecu so the engine is running rich. it is also a 6 speed car. a buddy of mine has a ECU from a 2002 camaro "auto car" already flashed for what i need which include ECU set up for no egr/air cats, rear o2 and LT's. can i switch out the two computers? i have the 241 heads etc as this car did aswell. so would switching the ecu help clean up my air to fuel ratio since that ECU was already tuned for it. either way he just gave the ecu to me cause he carbed his ls1 for his 66 chevelle.. thanks

 

no one knows if i can swap the two ECU's?

 

You can swap it but it will throw codes since its tuned for an auto and yours is a stick. Provided he had the same cam it should be close. Won't be exact, of course.

 

but codes can always be deleted right? i just want to get it running closer to the proper air to fuel ratio then save up money for a proper tune. it shouldnt cause any serious damage to the engine thou correct even if cams are slightly different? cause i am running way rich right now flames coming out my exhaust due to the free flowing exhaust.

 

Keep his computer and have it tuned, the 02 cars had the best PCM. It's hard to say if it will be better, it's not calibrated for your maf and 02s and everything. If you had a Wideband you could try it and see...

 

 

the 01-02 0411 pcm is the better pcm to have. Its not a must have but it is technically the better of the ones offered.

 

If Someone gave you an 0411 PCM your saying you wouldnt use it? I mean he got it free...

 

Your buddy has a 2002 PCM tuned for the [different] year 2000 injectors just laying about?

 

On the Aussie cars, using an auto calibration in a manual prevents the reverse lock out solenoid from functioning, making selecting reverse a real pita.
The quick way would be to get your mates pcm & a manual segment swap done to the tune to fix this & other issues. But if you were going that way you may as well get your own pcm tuned.

 

I don't think the 02 computer was tuned for his injectors. But it has been tuned for similar mods. I still say if you have a Wideband try it and watch close. If you don't have a Wideband your asking for trouble with either computer...
