    Hello guys, It’s me again. On ‘00 323i I recently bought I’ll have to replace whole lock system because old owner locked his keys inside the car and had to break the lock to get inside so I decided buying whole new lock system. First question: I got ECU, EWS Immobiliser, Drivers Door lock...

    Hello, I have a BMW 320i with the M54B22 engine with a manual transmission and it is my first ever project car. It has been running perfect ever since I got it and started every time without any issues. Until recently and now it won't start at all. I'll write my issue as detailed as possible and...

    Got into a noob problem, I bought an engine and the guy gave me two ECU’S he told me which ECU pairs with the engine but now I forgot, is there any other way I can identify which computer belongs to the engine?
  4. Engine Swaps
    I have an e46 sedan 2001 manual. Bevakar of a paper napkin getting past the oil filter my old engine was running dry which led to me swapping it to an m52tu, but keeping the m54 intake manifold, and basically everything but the block and top. After some minor misfortunes and setbacks, we finally...
  5. Forced Induction
    Currently I want more power from my car since it is awd and has so much potential for putting down more power. I did a little bit of research and found out that getting more power while naturally aspirated is just too expensive per hour gained compared to forced induction. My main question is...

    I have a E46 320d (M47TUD) which I am going to tune, the company offering the tune requires me to download the cars ECU myself, which I don't really know how to do. I have a K+Dcan cable and inpa + ncs expert, but I'm guessing I will need some other tool to download it? Could anyone point me...
  7. E46 General
    Hello, I decided to post here, because I have been to multiple repair shops and every single one of them refuses to look deeper into this issue that I have. I figured maybe somebody else had the exact same problem and had it fixed somehow. The thing is I have a 2002 E46 330d 135kw and it has a...

    So i tried doing it to the ignition last time cut the wire and it ended up cutting the wire and destroying my battery which i ended up paying like 550 in fixing it. How else can i make it work without the ignition wire.

    I just want to state, I am getting nothing from this, I just wanted to help any E46 guys if they are looking for a tune. Where do I start, So far, I think it is great! I mean you can't expect a lot from tuning an N/A car, but I can definitely feel a difference (I went with Stage 2...
  11. Electronics
    Unfortunately these DME issues don't have as much coverage as other issues on the forum. I have pretty much exactly the same scenario as this thread here, but the OP never posted a final update: Single Cylinder Misfire I opened up the DME and saw a cracked transistor. At this point I understand...

    Greetings, I have an M54b30 and I've been having an issue with the car behaving sluggish once reaching operating temperature, there's a night and day difference with torque output between driving it within the first 10 minutes of start up (when still running cold) and then once at operating...
  13. Europe
    Hey everyone! I just bought an E46 but the car can’t go over 110-120km/h like it should normally. I don’t think the car is in limp mode because it reaches 4000RPM but the engine struggles and I can hear the turbo but just sometimes not all the times when reving. The previous owner said the car...

    Hello, i have been trying to solve this issue for a few days, reading the Bentley manual and scowering through forums but have not crashed in to a solution. The car in question, a 2000 330xi wagon, automatic, has been sitting for five weeks, started every second week. Now, at the latest start...

    so I have a 03 325i that has headers and intake, Nothing crazy. I do have a ECU tune that I bought from rev match motorsport ($350) but it’s only stage one bare minimum. This summer I’m swapping my motor for the s54b30 and would like to be able to tune that ECU but don’t want to buy another tune...
  17. E46 M3
    Is there a way to reprogram the DSC software so that its not such a buzzkill? I love my 2002 M3 and appreciate the electronic nanny that kicks in every now and then, but dang- it feels way too immediate and brute. Any ECU flash/mods to address this? Thank you!
  18. Driveline, Performance, Tuning
    I recently just finished rebuilding and turbocharging my s54 in my 2002 e46 m3 and i am looking for a solution for engine management. The first thing i looked at was the aem infinity for the e46 m3 but after contacting multiple distributors it seems like the jumper harness was discontinued...

    Hello everyone. Continuing the saga on my e46 323ci shaking. I've came across this wonderful video by 50sKid showing how to diagnose engine problems using fuel trims. As the maniac i am, i followed every step just as described in the video, same adapter and software, and got the following...
