    Max here. Long time lurker, first time poster. I have an 05’ z4 with m50 manifold, catless headers, sap delete and a couple other bits and bobs. I installed a tune from chaoscalibrations but there was a lingering secondary air code that I can’t get rid of. The tuner has not been responding to...

    hello guys, my problem started with an unresponsive precat o2 sensor (b1s1 @ 0.42v). i looked at the female part of the cable and discovered that it had previously been spliced and covered over. i got new wires and spliced them in and it finally showed that the o2 sensor was operational, but i...

    Hey there, I am confused. I read like every thread I could find in regard to the Bosch BMS46 ECU, that is used for my M43B19 engine in the E46 316i with 105hp. I read all about KessV2, Galletto or MSSFlasher and other programs, but what do I really need to partially read this ECU? I already...
  6. Engine Swaps
    My son's 2006 X3 engine finally let go. It was on borrowed time from a previous head gasket replacement but that's another story. Anyway, I happen to have a 2.5 M54 engine sitting in the garage from a 2004 E46, again another story. So I swapped the 3.0 out to the junkyard and installed the 2.5...

    Hey there, maybe I just oversaw it or didn't use the search function right. But can someone please help me getting into ECU mapping? I saw tons of tools for almost every engine out there, but here I come with my 2001 E46, the 1.9l 316i (105hp) engine and the BMS46 ECU and have no idea where to...

    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?
  13. 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...
  14. 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...

    Greetings, currently dealing with a no spark condition on an M54 Engine, I've fitted a new crank sensor, tested and proven to work as intended. (Voltage Tested Signal Wire) My attention is now drawn to the ECU (and possibly EWS). I'm looking to test the pins on connector port x60005 of the ECU...

    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...
  17. 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...

    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...
