    So I did a pretest on my s50 full rebuild with stock everything else . Only one dme and MAF. The sniffer was about twice as much as the allowable . I have the stock oem 25+ year mid pipe and cats . Should I go to the red like that and have them tell me what’s up or should I just do new cats before I go in . About 1200$ installed for both at my local exhaust shop

      Went to the referee yesterday . S50 swap stock headers modified stock downpipe for clearance stock O2 sensor portion new walker cats . I have a red label 413 ecu apperently it’s out of an automatic and it wasn’t giving off the correct MPH signal . Also he wanted to see the actual ecu to verify the part number . So I failed because of the ecu . I need to find a manual ecu and when I go next time I have to have the glovebox taken apart so he can see the computer . I was hoping to pass first try . I was so close!! the ecu part is easily fixable . I have sourced a silver label ecu with the vin number that says it’s manual from a 95 M3 . I have an ews delete chip already so I’ll just swap it out and be okay I hope . I will report when I go back .

        Interesting that the ECU modifies the signal from the diff based on the type of trans.
        How is your ECU mounted currently? Mine's in the OEM location, I cut the bracket to make it wider, and use big washers with the stock bolts to hold it up. Easy for me to undo them for that visual inspection.

        So your emissions were good after the new cats? That's great to hear!

          it is in the stock location bolted up . He didn’t want to accept a picture of it . But I guess it wouldn’t have mattered as the automatic ecu is not letting it pass . I sourced an s50 95 m3 silver label 413 with the vin number intact that says it’s a manual . So I’m waiting for that to come in and I have an ews delete chip . When I go back I will just have the glovebox taken apart so that he can see the ecu . He did inspect the car for 2 hours . Said the swap was super clean . Said don’t worry no one passes the first try . Although he said I was super close . Should be good on my next visit

            Well I went back with a chipped silver label manual 413 ecu with the vin number present from a 95 M3 . Showed up with the glovebox taken apart so he could see it . Ran the tail pipe test and confirmed the ecu and boom I got my sticker . This was in Rancho Cucamonga chaffey college . Guy was pretty knowledgeable on older bmws .
