Hello, I have a 2000 gsr and I want to use a P73 (Type-R) ecu to past smog. The immobilzer on the P73 ecu has been removed, desoldered by the previous owner. The problem is that the P73 ecu throws the immobilizer check engine light, and I don't think I can pass like that.

To my understanding the immobilzer is the chip on the left pictured here:


Now, pictured here is the P72 (gsr) on the left and P73 (type-r) on the right.

Can I solder in my gsr immobilizer chip onto the P73 board? (therefore use my stock gsr key with no check engine light?)

 

Not 100% sure but I don't think you would throw any codes if you just swapped the ECU. Just drive it really lightly to the shop.

 

You will have CEL once you remove the imo. like it says.

i'm not asking if i'll throw a code or not, i'm asking if the immobilizer chip from the gsr ecu will work in the itr ecu
