Awesome we have a great collabo with Paul Johnson, here in Orlando there's so many S55(F80 M3) that have switched from other tuners/platform to us BM3Tuning x PJT for all the right reasons.

S58 is a true powerhorse, we've been tuning them with Paul since Nov 2019 when a few close customers bought their 2020 X3M.

So, finally was able to do a pull today. Car feels solid but I seem to have a data value issue still..I don't think my logs are showing true boost.

At idle, I'm registering 14psi when it should be zero.

Logs show I hit 38psi....(I assume if idle is showing as 14, then the 37-38 is really 23-24psi)


Sent Paul a note to see if he can make sense of this..I checked the engine bay against the jb4 install manual and I can confirm this car doesn't have one installed.

OP

Def worth getting E85 if you can but at least you'll have the E30 OTS if you want More Power.
I live in NJ too and there's actually 3 stations (but still far away)

BP Congers, NY
Power Gas East Orange, NJ
Exxon Newark Airport, NJ
Conoco U.S. 130 Cinnaminson, NJ
Exxon/MightyJoes Shamong, NJ

Since I travel often to NYC i stop by the many E85 stations over there across Yonkers, Mount Vernon, New Rochelle or New Hyde Park

Yea I'm on the far west side of Morris county. those are all way beyond reasonable distance for fuel most of the time. The closest one is East orange at approx 45 mins east of me lol so...99% of the time I would be only seeing 93 octane.

Hopefully one day soon they will put e85 in more areas.


Having said that, Paul advised 600-615whp for 93 octane tune.
I drive 1 hr each way for E85 in CT. Totally doable. 😆

So I looked up a few things and it seems the stock boost ramps from 16 to 20psi max up top (for Competition).

So really should be no way my log is correct as 37psi, should really be 25. Likely an issue with the app again.

**Update**

Realized it's set to read as PSIG and not PSI.

Whoops! Lol

Well, can't find the Bootmod3 wifi agent in stock anywhere, and having it hard wired while logging is kind of cumbersome.

So making a DIY wifi agent for BM3. If I need to flash the DME I will still use hard wired to the phone but I think it's okay to use the WiFi agent for data logging.

I had a raspberry pi 4 on hand but that apparently doesn't work with the firmware required so bought a raspberrypi 3 off eBay. Works!

Printed a case for it. Ordered heat sinks but it'll work as is.

Have it installed in the rear driver side cup holder. Maybe I should make a case that looks like the base of a cup to fit the cupholder shape.

This will work for now.

Alright so had a revision sent to me, did a second pull. This is with extra boost added. I see knock at 4170 rpms in third gear. Sent a note back to Paul about the knock, awaiting feedback.

Just got revision #2 from Paul. Im told it should address the knock in the lower RPMs as they have now richened it up and adjusted timing for that area.

Will do a pull tonight and report back.

Also - exploring the possibility of installing a meth kit. Should raise the octane a bit and cool the IATs, best i can do since i cant get E85 reasonably. But lets see how far we can take it on 93.

What image are you using to flash the raspberry Pi ?

The knock is related to the Heat + Low Octane and also these S58 are a bit sensitive to low rpm knock or part-throttle on pump gas

Hey, used the following:

https://www.dropbox.com/s/3bufcjcg3o...re.img.gz?dl=1


It has to be used in a raspberrypi 3 B, not B+ or raspberry pi 4.

I tried in a raspberry pi 4 and it didn't work.


Made a much better holder for it to fit into the rear cupholder, flush with a 30mm fan for chipset cooling.

Tested the revision that Paul sent, no more knocks during the pull. Went from 2k rpm in 3rd all the way to 7k, shifted to 4th went all the way to 7k shifted to 5th. No knocks. AFRs seem a little better but still a bit lean on the lower RPMs when on WOT.

Also another new thing that i noticed was the car is registering knock on the data logger at lower RPMs, like when im getting off a traffic light, touch the pedal a bit to have some engine load and the AFRs are getting as lean as mid 15s before causing knock to register. Was scary just driving home.

I've sent Paul the note - hopefully he can sort this out also.

This is awesome!
Did you manage to change the WiFi ID name ?
I tried to burn image to my old wifi agent but couldn't figure out how to ssh to raspberry.local anymore

Yep lower rpm these cars run lean even from factory

The SSID from the unit is the usual Bm3_NET. What are you using to burn the image to the SD card? I used https://www.balena.io/etcher/.

As for the stock AFRs, they hit 15? I couldn't imagine they knock from factory?

Yep, even from factory these S58 are overly sensitive and will knock on 91/93oct especially with higher temps

Yea I use Etcher, so you didnt change your hotspot name on your phone?
Because in the past I use to change the SSID from BM3 to my own unique so it connects automatically when I turned on hotspot on my phone.

Oh no, with this the raspberry pi will provide the WiFi access. You connect to it after signing into bm3 app. Once you sign in then connect to the bm3_net wifi (as you'll lose internet access) that the RPi3 hosts and your connected. You will need to make some adjustments to the wifi before you connect though. I'll post a screenshot with the items you need to statically assign.

I love the cupholder mount! Although I am exploring this type of setup to be able to use it among two different bm3 equipped vehicles. Saw these images on an old FS thread (not my idea), but I need to teach myself how to wire this up properly and buy a bm3 type case for the PI3...lol

Thanks for the comment on the cupholder mount. Yea, its relatively easy to set it up. Do you have a Raspberry Pi 3 B? If not, you can get them on ebay, got mine for like $75 but you can bid on them for 40-60 if you're patient.

Once you get it, just follow the link above for the file and for the software to burn that image onto the SD card. After that its plug and play.

Yup...It's on it's way to me. Much appreciated for giving me the idea
