hi,I have Prelude h22a automatic transmission,I has installed P28 ECU,automatic transmission not work.Who to use this, possible use P28 ECU for Prelude h22a automatic transmission ???

 

not possible???

 

You can't do that. Only the stock ecu will work properly with the tranny computer. You cannot use a replacement ecu in that car.

You might be able to use an auto p13. The idea has been thrown around but to my knowledge no one has tried it.

 

much bad

 

heeeelp

 

Help with what? The ecu won't work in your car.
