Can't believe i've found a place where people appreciate the Civic Vx/Vei as much as i do! I've had mine 5 years or so and have always been amazed at how unknown this car's abilites are.
I'm a big Honda enthusiast - especially EG's.
I found this site looking for help to find out what is wrong with my poor EG4. It's got a drink problem (I bet this is how most people find this site ). So i shall be having a good old dig around this forum looking for answers.
One thing I do know about the Vei that is different than the VX stateside, is the programming. Your ECU/ECM would read 37820-P07-XXX where "XXX" would be a letter and two numbers (A00/A01 and L00 stateside) But yours is even different than ours. Other than that, they seem to have the same EGR and O2 systems and we should be able to help you out.
A great place to start is the "VX Info" link in my signature.
