They've posted several in this thread and in the facebook group. Check their Instagram. They always post them there first.

nope, just Stage 2 graphs...

Alright I'll share when I found one. I know I've seen them posted up by users, but as people in the thread commented some start with MPPSK, some have an intake, some have stock downpipe with stage 2, so they're all going to be different. If you want a specific setup you'll need to do some real digging. But basically it's 380whp-400whp on stock setup.

Like I'd love to get my 93 octane stage 1 map dyno'd but I have a muffler delete. So i know that still won't satisfy some of people in the thread. And I don't have a stock dyno to compare it to.

And if it's not already painfully obvious, people are moving away from dynos and focusing more on times recorded by dragy setups, so it's more rare to see dyno graphs. folks don't even go to the drag strip anymore. just post draggy screenshots.

The reality is draggy gives you a true, no BS, real world road view. The dyno can vary between units, runs, IAT temps etc.

But I do like the dyno plot for the "cool and warm fuzzy feeling"

Yeah at the end of the day I want to know how much power I'm making. But I see where things are headed. The only thing limiting it is people not wanting to speed on city streets.

The Dragy runs are not necessarily comparable either though. You don't know the weather conditions, elevation or the IAT's the runs originated from, so it's still not the same as two cars running side by side in real time.

[Wires]

True enough. On the dyno you don't get IAT numbers though. The end HP is typically SAE corrected for elevation/weather, but numbers off different dyno's don't always jive (IE Mustang vs Dynojet).

I do like the bragging rights number though. Not going to lie.

All I can say is my butt dyno isn't lying when I say I'm loving the BM3. It is forcing me to "waste" money on a downpipe so I can do Stage 2 though.

[ScubaJ813]

Can you guys give me a read on these logs? Still learning and new into tuning. Just re-flashed to the v1.6 of the Stage 2 93o.

http://www.bootmod3.net/log?id=5ce21936c090c67d3eb9a273

Any feedback would be appreciated. I haven't been able to do anything but some spirited driving, so the log is very limited. I just want to make sure things look OK.

I'd need to see their baseline vs stage 1 / 2 before making that assumption. They could be similar deltas between MHD and BM3, which is what really matters.

You do. Dragy added that feature recently.

I don't want to take this topic off thread, but does anyone else who is using a dragy have any mph differences between the unit and speedometer? My dragy is always 2mph behind my speedometer so if my speedo shows 60, the dragy shows 58mph. Any way to calibrate it? I always make sure I am at a standstill and on as flat as surface I can be when linking to the satellites.

Most newer cars read 1-2mph higher than their actual speed.

you can remove the compensation in the speedo via coding. it's the OEMs way of protecting you, so you won't get a ticket when you think you're driving the speed limit. So it's a little optimistic in your speed readings. Dragy measures your actual speed via gps.

Look for something like this in KOMBI:

BC_V_KORREKTUR = Correction for Analog Speed
BC_DIGITAL_V_KORREKTUR = Correction for Digital speed

Its actually some European law to deal with differences in tire diameter. The speedometer cannot display a speed lower than the car is moving at, so they toss in a 5% "error".

Annoying for everyone outside the EU though. I coded mine out.

same...

...then i got aftermarket wheels and tires that weren't the same diameter as OEM, and now it's off again luckily my radar detector displays speed via gps if i ever need a reality check.

[MTWO]

Yeah true but you can code this off as mentioned its not hard

Gonna buy this tomorrow but I got one last question; for stage 1, do you need to do anything to the car (ie space out spark plugs) or anything note-worthy?

Also another quick question; I have a 2018 Macbook Pro what kind of cable would I need to buy?

last I looked, couple used B58 licenses available - check the classifieds if you want to save some money

[omgthedonny]

I searched the thread but couldn't find an answer to my questions specifically; I have 340i MSport with MPPSK (RWD), I live in California and only use 91 Octane gas.

1) With my setup will I see gains by using this?

2) would it be any better to getting a DP while still staying on 91oct?

Thanks in advance!

You'll definitely notice a difference going to Stage 1. Even a downpipe on the stock MPPSK Tune is noticeable. The Stage 2 is just brutal.

You don't need anything. My engine is completely stock and stage 1 works great.

you need an enet cable that plugs into your ethernet port. if your laptop doesn't have an ethernet port, you'll need an ethernet adapter.

Can you run stage 2 on 91oct automatic MPPSK or does it require more?
