Sad to hear that, what happened? My car is currently 92k km and running strong (stage 2 since 80k km).

New plugs, coils, oil every 8k km and shell v-power racing only gets into the tank. Timing chain and oil pump already have been revisited at 70k km.

Also my car has been fully logged under the maximum load and everything is more then fine. For example IAT are around 30 degrees Celcius (compared to 60 degrees Celcius with the stock FMIC ).

Even with a 1/4 slip, we'd have to calculate differences due to weather, but it at least doesn't have the added variable of the dynos calibration.

Yeah, let's stay in touch . The n20 clan noblesse oblige.

I am curious myself, till now I have ran several 0-100km/h times with driftbox and the best I have achieved is 5.1 sec. The car is RWD.

Would AWD shave time off? You lose time waiting for the tires to grip, no?

I have Stage 1 BM3 rn on my 320. Would recommend it. I have only heard of FloridaOranges unlucky with his engine, but you figure one engine over a few thousand or so isn't too bad of a failure rate.

You must be lucky - or part of PTF PR team - mine had 48k miles and started with a really rough idle then threw a drivetrain malfunction and did eternal damage that wasn't fixable.(joking of course about the PR)

As long as the tires aren't bald, over inflated, or track is terribly prepped... you won't spin at these power levels.

I'm rwd and almost never spin unless I do something wrong in the launch.

AWD will have slightly better 60ft times (maybe 1.7 vs RWD with 1.8-1.9) but will have a lower trap speed (maybe 101-105 with RWD at 105-109) so it ends up balancing out for the most part. The two fastest n20s currently are RWD.

Hehe, my tires spun every time I launched the car (manually brake boosting at 1.8k RPM) - hankook's evo2 255/35 at the rear on 19 inch wheels.

My torque seems to be high though (around 450nm at the crank, the maxium that I wanted to have due to preservation of the cylinder head and the ZF transmission) - at least according to the magic dyno .

However, I have driven recently my friend's stock 330i with the b48 and I have to say that his torque does not compare lol. Top end also dies thanks to the eco-map and the cat being in place .

floridaorange I had a rough idle issue too last year, swaped the coils and the problem seems to be gone. To be honest this n20 idles rough from the very beginning, even with the stock map of 180 bhp.

I am suprised tbh that you had both FMIC and the downpipe installed, rigorous maintenance and the piston blew. Were the other pistons fine? Have you found out the possible cause?

@[Steakpizza] Haha you are right, let's keep fingers crossed for the head not to crack and pistons not to blow . Assuming that the dyno's number are correct and a 15% drivetrain loss I am making 280wtq (ftlb), which doesn't seem too excessive but high enough.

And btw. my gains seems to be similar to those of the JB4 map5 .

BM3 is currently my preferred, mainly due to it being more popular, so a larger sample size of people have tested it and proved. MGF claims stage 1 flash results in same power and torque for both 320i and 330i - doesn't make sense to me. Also, the logging function is included on BM3 but for MGF it is an additional 99 USD/EUR, so the price isn't too far away from BM3.

I guess the benefit of MGF is the ease of flashing from phone with ENET to phone, or wifi agent. I know a wifi agent can be made for BM3 but required additional unit which needs usb input. MGF also has a very good dummy guide on installation.

That's what Im getting at, I looked at MGF yesterday but can't find much about them, the only advantage I see them over BM3 is the price, but I think its better to save up the extra buck and go with BM3.

Still looking forward to reading what people are running. Im not trying to get it to 300hp or anyhting, 240ish to the wheels stock would be the sweet spot imo.

Sorry to hear about the blown engine, but also good to hear that it's running fine on stage 2. I think ill stick with stage 1 for now

Hi! I have bootmod3 stage 1 on my 2017 320i. I'm at around 260hp and around 310 torque. My 0-60 is 4.93 seconds- faster than a stock 328i/30i. I also have a k&n drop in air filter. In addition, I also coded Sports Automatic Transmission and Sport + using BimmerCode. I chose bootmod3 because it adjusts all parameters rather than just a few- which is what a piggy back does. Thus making it safer. Also, the customer support of PFT is phenomenal. They are always updating the maps which is incredible. Data logging and stuff are easy with the WiFi agent. Overall, I love bootmod3 stage 1. The power is incredible. It reallllllly wakes the car up. Especially with the transmission flash they have. Both in conjunction have brought my 0-60 to 4.93 second. And trust me, you can really feel it

Is your car rwd? My 320 is awd and my best 0-60 with MG is 4.55. Now I have xhp st3 and hoping to improve these numbers when weather will be fine.
Here’s dragy screen.

Wow that's amazing!! I have RWD haha. 4.55 is damn impressive man

Actually 4,93 is also very impressive for rwd and st1 tune!

I need to get dragy and do more accurate runs. What I would do is use the obd wifi agent and screen recorded on my phone and just trim the video down 😂

That’s not right)) could be completely inaccurate.

But it's through the obd port! It literally reads out whatever the car is saying. Maybe the inaccuracy is with the trimming of the video. If anything, my car would be faster than 4.93 because it can only allow me to trim so much.

But you don’t know the slope... could be downhill. But I trust dragy or RL more anyway. Both of them shows almost the same numbers as racing telemetry.

What do you mean by downhill?

That is impressive. Is yours the B48 engine? My car is a manual so don't think I will achieve those times. I would be happy with anything between 5-6 seconds. The main thing I want is more low end torque, I came from e90 320d which had great low end torque, 320i seems a bit flat in the low rpms.

I have a 2017 320i with N20 engine. Even if you have manual, you will still be able to achieve times lower than 5 seconds! Go for bootmod3 man. Super reliable and amazing!

2017 with n20? not B48?

How are you guys launching the car, LC? I can't manage to get below 5 sec 0-100 km/h (which is 0-62.14 mph).

Yeah I haven't tested my car but my Stage 1 seems like 5.3-5.4ish. I would have imagined at Stage 2, at best you'd be 4.9-5 seconds. 4.6 is crazy though.

Impossible. Just buy a dragy and you will get something like 5.4-5.6s. Mine is awd with (420nm, 290hp) get 5.4sec 0-100km/h
