I have a Civic LX with VX (vtec-e) engine, the I'm pretty sure that I need a VTEC ecu so I can pass the emissions test. So I was wondering if I can use an ECU other than a p07 in that engine setup. I'm just looking to get this car running right, not racing or anything.

 

No, you need a VX ECU. The VTEC-E system and stock wideband O2 sensor will confuse other computers.

VX ECU's are pretty cheap, why not just get one of those?

 

I'm not having the best of luck finding one

 

what codes is it throwing. perhaps i can help you into rewiring it to not do that.?
