swapping engines, immobilser problem?

[jdm ek]

ive just been told that if i replace the engine and the ecu in my 97 ek hatch that the keys will need changing/re-coding to work the immobilser, has anybody every done an engine + ecu swap and found the immobiliser a problem?

there are ways to disable the immobilizer, they do it on Pigludes.

It depends on what ecu you plan on using. Civics in the USA didn't have immobi systems until 2001.

how would i disable it, or do you have a website link i can follow?

First if its a 97 you should have no problem, second you should convert to obd1 with a jumper hardness. Last what motor you plan on swaping?

[jdm ek]

i have the d14a4 in my 97 ek, im changing to the d15z6 from a 98 ek so same series.

Going obd1 to d14a4/3 engine is not so easy as to other honda engines. Apart from the harness you need another dizzy, sensors, TB, and IMO

hmm i was wondering the same for me. car is a 97 ex with the in key immobiliser but i was wondering if i could go obd1 and of course chip and KEEP the immobiliser.. ive no idea where the control box for the immobiliser is.. usually in the head unit no? if it has anything to do with the ecu i may have a problem...

[jdm ek]

the immobiliser on the ek hatch is in a combination of 3, you have the chip in the key, a transponder unit under the dash on the driver side (small black box as im told) and then you have it programmed into the ecu aswell, so im not sure how you would convert to obd1 and keep the honda immobiliser as obd1 ecus dont have it programmed in.

i dont fancy converting to obd1 as its not too simple and in the uk its actually illegal as far as i know. all i want to do for now is remove/disable the immobiliser, if anybody knows how to do this let me know.
