Thank you and happy new year to you too! And thank for replying my post.
Don't worry. My English is bad too.
Okay, here my problems.
I have transplant a YRV engine (ECU P88) to my Myvi (Passo/Boon/Sirion in Japan). When everything is done, my engine cannot start due to I believe a key transponder problem. For now I stuck using un-immobilized ECU which is P39.
So my question is:
Is what I'am doing is safe? In term of engine system function or it reliability?
Is there any way to used back my original ecu P88 by bypassing the immobilizer?
