About
I probably started out just like you. Before I even got my E46 M3 I spent countless hours a day scavenging the BMW, Craigslist, Autotrader, BMW forums trying to find that super clean E46 M3.
How I Found My E46 M3
For me personally I wanted an Alpine White, at least a 2003, 6 speed manual transmission, and it had to be somewhat close by so I can pick it up. After 11 months of intense searching, I found it. It was 300+ miles away in Chandler, AZ which was about a 6 hour drive or 1 hour flight from where I am Southern California. I did all my pre-inspection checks and everything came out fine. I decided it was time to buy. I committed to purchase with the seller and bought a one-way airfare to Arizona. The current owner, at the time, picked me up at the airport and we went straight to the bank. I signed papers and soon enough, I was calling my friends and telling them to meet me in about 5 hours. I got an E46 M3!
What I Learned
Ever since then, my life has been all about my car. I can’t keep my cars stock. I have some sort of addiction to modifying. So off I went searching parts and researching everything I can do for the E46 M3. But it wasn’t all about modifying. When you play, you gotta pay. I quickly learned about all the maintenance required to keep our cars in good shape. And I quickly learned how to do my oil change. Like most of you, we all did some homework before we got our E46 M3 so of course the dreadful subframe issue, rod bearing and VANOS issues are floating inside the back of our minds. I’m also thinking of Inspection I and II services, fluid changes, cooling system refresh, etc. Whether it’s maintenance related or modifying, I want to document and share my experience.
Why I Started Buildjournal
I started Buildjournal as a build journal, as they say on the forums. It was purely just a website to showcase some of my projects and photos. Five years later, that is still what it is today, but we’ve grown a bit. Along with our DIY guides, reviews, news, tech guides and videos, we also tune S54 engines and code F30 vehicles. Why only those 2? Well because, that’s what I personally drive. For whatever work I do on my cars, this is where it’ll be showcased.
My goal is to have Buildjournal to be the highest quality website catering to the E46 M3 crowd – for all types of content. I hope you enjoy all the articles I create and services we provide, but at the end of the day, I do this because I enjoy it.

Hi can you sell the aluminum caliper brackets alone? (to adapt the brembo renault kit for M3 E92)
need you to restock the e46 m3 side splitters bro
Using your BMW e46 me fuel starvation kit diy. Your instructions are to rotate the pump CLOCKWISE 45°. The is a hump in the tank at that location the prohibits the pump from dropping into place. Your pictures and the instructions seem to conflict.
I have an 04 M3. Can we discuss the suspension setup information that is provided here?
I have a 2006 E46 M3 Convertible with 30k on the clock. I have no clue what the maintenance schedule is. Is there a way I can give you a phone call as I am also interested in the B-Spec tune primarily for the oil (as opposed to water) temperature lights on RPM gauge and the HP / torque gains with a smooth delta. Please advise….Regards….
Hi,
You can find our maintenance guide here: https://thebuildjournal.com/tech-guides/bmw-e46-m3-maintenance-guide/
If you have any questions regarding the B-Spec Tune, please email us at info@thebuildjournal.com. Thanks!
I know you mentioned that you are doing build for the E46 M3 because you have the M3. Would you consider doing a tune for the E46 330ci? The car has been on the market for so long and has been an enthusiast car for track and such but not a lot of people are not making good tunes for it. The stock tune on the car could use an update. Thanks
Hi Kyvin,
Unfortunately, we do not have plans for anything outside of the E46 M3.
Hello I’m looking at getting the engine and SMG tune for my e46 M3. Do I need a flex sensor in order to use the e30-e85 option from you guys? Or can I run it with out the sensor as long as it is tuned via DME?
Can this be done on a Apple computer?
Hi Michael,
Yes, you can flash with Windows or Mac. Email us for more info at info@thebuildjournal.com.
HI there,
I am interested in the B spec tune for my 2002 e46 M3 6mt.
A few questions-
I see the option for “local tune”, since I am in Santa Barbara, does this mean I can come to you for the flash?
I am running supersprint catless headers, and also a euro catted section one. Does this mean there is no chance of running the burble in any stage if I don’t want to damage the cats? So when ordering on the drop down do I select catted or catless?
Being that I have cats and all sensors hooked up, I don’t get a CEL so are any of the add ons around this needed?
Are there any of the other technical add ons that would be suggested? regarding the DTC, cat monitoring, SAP, EGT, etc..?
Thanks and let me know as soon as you can, I am anxious to get this ordered and flashed!!!

Hi Jasun,
Please email us at info@thebuildjournal.com. We can chat via email.
Hey! I am interested in getting either the burble tune or B-spec with add-ons. I was hoping to get more information about the sport memory button. I read the ECUWorx website with descriptions of the different add-ons but was confused specifically about the sport mode button functions. Could you elaborate on the different choices for the sport button options? Thanks!
Hi Blake,
Thanks for reaching out. The sport memory add-on means that the car will remember the last mode that it was on and start up with it. This is useful if you decide to choose our Valet Mode and Sport Enhanced Mode add-on. We are able to reformat the maps for when your sport button is ON or OFF.
For example, if you chose to get the sport-enhanced and valet mode – your car would remember the last selection you had. Say the last time you were driving you had the sport button ON, which was on sport-enhanced mode, the next time you start your car, the car will already be in sport enhanced mode. If you were previously driving in valet mode with the sport button OFF, the next time you start the car, the car will start up in valet mode with sport button off.
If you get just sport-enhanced mode:
SPORT BUTTON ON: Sport-enhanced mode (more linear throttle mapping)
SPORT BUTTON OFF: Factory comfort mode
If you get just valet mode:
SPORT BUTTON ON: Factory comfort mode
SPORT BUTTON OFF: Valet mode (reduced power mode)
If you get valet + sport-enhanced mode:
SPORT BUTTON ON: Sport-enhanced mode (more linear throttle mapping)
SPORT BUTTON OFF: Valet mode (reduced power mode)
If you have any other questions, please email us at info@thebuildjournal.com.
Hey I want to buy a burble tune for me e46 m3 for $50.00 does this ship to my house like a drive or chip I can install on the car or is it a software because I do not own a laptop.
Hi,
I have a couple questions regarding your B-Spec tune. I am in the process of converting my SMG to the 6MT and I don’t want to deal with re-coding the modules myself. Does your tune reflash the entire DME? Would this be useful for a manual conversion/swap?
Hi. Thanks for reaching out. There are other modules you’ll need to code out such as paddle shifter programming and some of these may require INPA coding. Our tune should, by the book, allow for a SMG to 6MT DME conversion however I can’t confirm if it will give your car 100% functionality.
