I recently swapped out my 97 Accord LX f22 and replaced it with 2001 F23 and my problem is I want to use a 97-99 prelude ECU. I have 97 H22 ECU but it has an immobilizer how or what should I use or do, to get the immobilizer removed. I also purchased a wiring harness OBD2A to OBD1. any suggestion

 

If your looking to stay OBD2. Sell the 97 ECU and buy a 96 OBD2A Prelude ECU that doesn't have the immobilizer. I think they are getting harder to find now-a-days. May have to go to an OBD1 ECU and use that conversion harness you bought.

Why did you buy a conversion harness when you already have an OBD2A ECU and an OBD2A vehicle?

 

^^^ exactly 97 is obd2a man u dont need a obd1 to obd2a wiring harnest lol

 

My 97 ACCORD LX is a non Vtech thats why I need a different ECU and plus I want to use a Prellude ECU. Thanks for the suggestions and tips

 

If all you want is the ECU just because it's from a Prelude, you could save yourself some time and money. Get yourself a chipped OBD1 ECU that will work exactly the same as a Prelude ECU. That is as long as you do not require any sort of computer testing to pass emissions laws.

An automatic P06 Civic ECU can be converted to a manual, VTEC ECU with IAB control very easily. I may have one or two P06 ECUs laying around if your interested.
