Now, I'm happily reporting to you all it was a success.

I ended up finding a guy (karman auto), a quick call/text verifying it could be done. I called a few so cal shops, left voicemails for a few of them-crickets. Turned away, I returned home and spent the evening on google, looking for anything I could find on this mismatch issue and resolutions. I have friends w/ swapped GC's and this never came up in convos.įoot in mouth I explain a bit about my car and let him know I had planned to go to the state ref when it was all said and done, it's CA, that's like mandatory here haha. I can't believe I overlooked this step, I've never encountered. I reply like an idiot, that's right the swap and 05 ecu. He turns to me and tells me, "I can't do it bro." Unbeknown to me the 05+ ECU's have the vin written in them as mentioned (proficient HA! What a spectacle, lol). As I hand him the registration he goes straight for the vin, to match the two. He hooks the car up vin loads on his machine he asks for the registration, the standard basics. Seller was a hack in the end, proficiency "corrected" that.įast forward 4 months, car up and running, I take the maiden voyage to the smog shop. Big gamble, but I was confident in the sellers honesty and proficient in my skill to get it running. I'll do my best to make my back story comprehensive, I can summarize it now that I think about it that should help.īack in July, I had purchased an 02 RS w/ a non running STI conversion. Hey Charlie, the bold was my exact issue. Seems like some states also match ECU VIN to registration (during inspection) which may be an issue if they don't match. Usually, not an issue as long as year and model match. So a used ECU will not match the car VIN if swapped. Interesting, my understanding on most years, once the VIN is burned in, that's it.
