Your immobilizer will not work and engine will run poorly.
I have the stock k20a3 in my 2003 ep3. I cannot get rid of p0171. I have jdm ecu that came with the k20a engine and was wondering if it'll run better with the jdm ecu. 37820-pnc-905 are the numbers on the one I want to immobilize.

What do you recommend I do? I have a p0171 it's not going away. Should I just put the jdm ecu in since it came with the engine?
