I have an 2001 Teggy I put a 2000 h22a inside. The car runs fine and I have a harness adapter allowing me to run a p28. Now I need to get emissions done and need to buy an obd2 ecu.
I have looked around and some people say you can buy a 1996 prelude ecu because it has no mobilizer but there like 200-300$ are there any cheaper options. I only need the ecu for like 1 hour lol to pass emissions

Remove the immobilizer from your 2000 ecu.

Doctronic - smart solutions - Mobilizer-FX01

They used to be available from domestically from Xenocron but they have recently closed down.

You'll most likely need a stock ecu for more than an hour - you'll have to at least drive around enough to set all the readiness monitors.

 

Spending $200-300 is cheaper than moving to a state that doesn't have emissions tests... get the '96 ECU and use it once a year as spAdam stated above and you will likely be fine... assuming you still have a Cat and a secondary O2 sensor.

 

'96 ecu is not a practical option in a '00 chassis. Not sure is preludes went to OBD2B in 99 or 00, but it needs to be of that same gen.

Replacing the Immo board with the dummy one I linked to is THE way. I did one on a P75 last year:



If you're less than technically inclined, looks like you can send your ecu to HAM and have them do it for you: https://www.hamotorsports.com/produc...emoval-service
