This might be an ignorant question, but I am looking to put the stock ECU back on the car. Other than reinstalling the OEM ECU, do I need to reinstall parts that were replaced (crank sensor, crank wheel, AP1 valve cover, etc.)? Thanks.

 

Yes you need to replace the sensors/trigger wheels/valve cover

 

Also, the reason your particular car has KPro, is because none of the emissions stuff is still there. You would also need to replace the front emissions air pump and all of the charcoal canister stuff in the rear. With KPro, you can still pass Texas emissions without that stuff. You would also need the stock ECU, which I don't think you have....

 

if you are in TX, i'll take it off your hands.. i have my stock air pump sitting in a box, perhaps we can work out a trade.

 

Thanks for all the responses everyone!

Ahh no wonder why I get this gas smell all the time! I have a spare 02 ECU sitting here. I think I can just get the dealer to program the immobilizer to match the keys.

 

I'm in Idaho.
