Learning to custom tune with BM3

- I wanted to get some content out so I figured I would show you guys how I went about tuning my car. I am not an expert nor do I claim to be. This video is simply informational and shows how I learned to build my custom tune with Bootmod3.

Keep this shit up I wanna seee that big turbo and see how it pulls
No guarantees but hopefully I can have it all back together soon, I am building a new manifold for the turbo right now. I have the first half filmed, just need to get it out.
I've got my tuner account set up and access to the map editor. Being in IT for the last 25 years, i at least have an appreciation for how much i don't know about tuning given how many databases are in this configuration, and how many relations i see when clicking to see dependencies. I appreciate this video - i do want to get to a point where i can flash my own tune...
There are a ton of tables but most of them aren't used. Really, you just need the fuel and air to start then you can start working on ignition timing. Flashing is pretty easy, you can do it from the custom tune screen. With the N20 there aren't custom roms but if you jave a newer car you can live tune through the tuning editor. Let me know if you have any questions, not a pro but I'll help where I can!
@@projectrandomCO so off the bat start with AFR table? what about boost target/ceiling, my understand is altering this value will effect the max boost slider in the config settings when you are about to flash, when adjusting afrs with ignition timing should you increase this value?
The reason your stoich value is 14.1 instead of 14.7 is because they are designing cars to run on E10 now. Also, the reason that E85 or its variants require more fuel is not because of octane, but the fact that the energy density of the fuel itself is lower than gasoline.
please keep these up, im forging my b48 and want to tune it myself pre forge and post forge, on bm3 ots stage 2 right now
Hello, nice video, thanks for sharing👍 Can you help me to turn off the torq limiter at stock map?
Lookin good.
Can you do a dyno test! We love to see it
Maybe, lol those are expensive. I have the manifold off and all cut up right now so I can rebuild it. Once I get it back together I will definitely get some footage.
subed, liked and following. any b58 love in the future? more in depth with reflex+ tuning for port injection?
Maybe! I need some more funds and projects for sure
I was thinking something, you can also plug the injectors and run a port injection with another stand alone ecu like fueltech
That seems like overkill haha but I am sure it's possible. Maybe if I ever get a fully billet block and really want to go full race car. I think I'll get a different platform for that though.
@@projectrandomCO got that thinking after seeing a video of somebody installing fueltech ecu on a n54 and running a plug ( injector delete) and new injectors on the port intejction by the intake
gotta see how it runs :D
Yo, working on it now. I am rebuilding the manifold so the turbo is off the car currently.
@@projectrandomCO very nice, i am very excited😁 Im looking for a 320i to modify myself and im getting alot of inspiration from you👍👍
Do you know if this is what's necessary to have map switching capabilities? This is what BM3 refers to as "customROM" right? I dont want anything fancy, im just looking for the ability to toggle between 2 or 3 OTS maps for my N55.
Hey, map switching is only available in some ROMS my DME isn't compatible unfortunately.
makes me want to grenade a 320i just to see the potential...keep us updated on your big turbo numbers (boost, afr, and power its putting down), dyno soon?
I probably won't dyno right away but I will def post as much info as I can when everything is 100% I want to shoot for 22-25 psi, maybe more on the top end to keep the trans safe for now until I can get that upgraded.
@@projectrandomCO what's the max the trans can handle?
I wouldn't go over 350-400 ft lbs of torque on the stock auto. If you bring the power in later in the rpm range you can put alot more power down. Less stress on everything since it's already moving. There are a handful of transmission companies that build billet internals for the zf45hp from 800-1500hp.
