Hey i am looking to purchase a 98 boxster from a friend who needs space in the garage. the original 2.5 blew up and he installed a 2.7 at a local German mechanic. I cant get it to pass smog because it keeps throwing p1124 and 1126. I spoke with the guy who swapped it and it sounds like they kept the original DME and MAF and did not flash the DME for the new engine. I have never had a Porsche before so i am a bit green, but it seems like it runs OK, but not optimal. Any ideas on how i can get this thing to pass smog? I ccouldnt tell if erlinrys kept his original DME or swapped in the one from the new engine, any insight would be helpful.
