Got my 96 odyssey last year due to a growing family, I'm always a Honda freak guy, whatever or whoever talk to me about cars, all I can say is just about Honda. LOL.
Anyway long story short, its been a great van for the last year, but sadly I really feel the ody so under power when it goes up on the hill or even cruising and taking off ( I live in Vancouver, BC, lots of uphill around where I live). Thats why I picked up a H22A4 engine for darn cheap ($150 including manual tranny and all the harnesses), so basically I can just sell the tranny and make all my money back but free engine.
I've been searching enough for doing this swap, about mounts, hoses, axles, harnesses yada yada yada... I got all the answer for it since 1st gen ody is just like a 94-97 accord with a different body, now the only thing that stuck me up from doing the swap is what ECU that I need to run to stay automatic (I have to stay automatic because the wife is the one that drive the van most of the time).
I know that F22B6 auto tranny will bolt right up into H22A4 block, but which ECU that I need to run is my big concern up to now, as far as I know I need a 96 H22A1 automatic prelude is the go, but finding this ECU will be so tough since they only make it in 1 year only, and I cant use 97-01 prelude ECU since it got a build in Immobilizer in ECU. And also I know that since my van is 96 so the Transmission control module is built in the ECU, unlike the OBD1 car that got a seperate TCU.
After a long search I found another way is to use a OBD1 JDM P0F ECU and TCU out of a OBD1 JDM H22A Accord, and convert my van into OBD1 (Either I will have to make my own conversion harnesses or de-pin and re-pin the ECU and TCU connector and adapt it to OBD1) I really have no problem with it, I got all the wiring diagram as well as I'm confident doing it.
Well, since P0F ECU and TCU is out of an accord, then i will have to convert my 96 Ody ECU plug into OBD1 Accord ECU plug.
Now, my real question is, have anybody done this way before? Is the JDM P0F ECU and TCU will plug and play my set up?
Or is there any other way of doing it? I really dont want to use a Chip ECU even though I got lots of P28 ECU lying around in my house ( did lots couple B-series swap into civic, LOL), because as far as I know if I use a chip ECU then i wont be able to change my shift point.
How did you guys do your H22A swap into your odyssey? which ECU that you guys running on?
Thanks in advance for all the advises that will come.
