i live in texas. i have to have my car tested on an emissions dyno and they stick a sniffer in the exhaust. it is not too hard to pass, like the california emissions test is.

i have a b16 with all smog stuff hooked up. will i be OK with a jdm p30?

does the jdm ecu eliminate something important or anything like that, or is the reason that cali people cant pass with a jdm ecu only because it wont pass visual?

i dont have either ecu yet i will but an ecu today and i would like to get what would be best suited for my engine.

 

if you are going to a REF, your ECU better have the USDM sticker on it at the least. I had a H22 eg and used a JDM P13 ecu but I had a USDM cover on it so it looked USDM. I passed with flying colors and this was at the REF to make the car street legal.

I know JDM ECU's should pass, its the visual that would not (ONLY if you get someone who knows what they are looking for).

good luck

My JDM motor with JDM ecu passed the smog test in illinois no problem, I'm about to try again with my turbo this year

 

thanks for the info
