To a certain extent yes you can improve the rate you are receiving samples. The rate the data is sent is based on whats being requested.

Limited bandwidth through OBD Protocol. It all depends on what you want to see

How do you plan to mount the head unit? In the radio slot? Or sunglass holder? I've debated this forever

Its a 7" Single Din LCD head-unit that flips downwards so it doesn't block my vent. It has 2 Composite AV Inputs.

Ill use a VGA to composite RCA converter to connect to a motherboard that will be mounted in the glove box. And I'll control it with a wired track-pad

you can get faster logging through SSM protocol. It's what romraider uses.

Thanks I'll look into Ssm

Next step is mounting the motherboard and components in the glove box

I have zero knowledge of MS.

Any good write ups online as to how it works and its benefits?

Not trying to talk you out of what you have since its working, I just think its funny when people spend $1500 on dataloggers and failsafes and boost controllers and traction control system and displays and ect, ect, ect... just to do what a single standalone can do.

My intention originally was to get the car up and running as soon as possible, which is why I went with the DME tune. Now that I drove the car and got a bit of 'it' out of my system I'm starting to fine tune things a bit. I bought quality parts just in case I ever wanted to sell them (higher resale value)

I needed a new head unit, mine died. LCD unit cost me $100
I've been doing IT since I was like 15 so the parts for the computer I already had
I purchased the OBD scan tool probably like 8 years ago and the software didn't cost me anything either.

So I'm out $100 bucks for on-board data logging, diagnostics, and remote tuning anytime, etc...

I really need to get the car 'officially' on the road, enjoy it for a bit, and then start looking into standalone and possibly building a bottom end for future endeavors.

... And maybe sourcing an M3 complete rear to swap in as well

Still can't figure out why this car starts missing when its warm at 14.7 afr. If I unplug the O2 the car idles fine but rich ofcourse. I'm sure its not vacuum leak, I've had 4 different manifolds on the car.

I did finish the PC install and played around with it all little bit. Only thing that is odd to me according to the OBDII port Intake, Coolant, RPMS, and TPS will randomly to shoot sky high numbers and then go back to their original readings:



Guess I'll just leave the O2 Disconnected.

Car also has idle hunt after being revved
installed a little analog boost gauge for a second boost reference. Eboost street 2 will flash "OBS" continually when you hit your peak set level so your really don't know what your PSI is when its flashing

That’s some hi tech stuff you got there. Impressive

Thanks T-Bone.

Capabilities are endless with an on-board PC

Refresh actually looks semi decent.
Here's a video I made yesterday for someone else to show the comparison between bluetooth obd2 and stock analog revs.

Yeah, its really not that bad.

Also depends on how many PID's your pulling simultaneously as well

I used to run OBDII software years ago and I don't remember it being that slow

Ran some zeitronix data logging with the on board PC today. Worked flawlessly. Just ordered a MAP sensor and plan to log, boost, AFR, and RPM anytime the car is turned on.

Hey guys, What think AFRS?

I usually compare it to load % and rpm. It's hard to tell where you are on the pull with just AFR

Yeah I know :/

Got a map sensor on the way. Will connect it and tap into RPMS as well.

Wanted to drive the car this weekend but may want until I log correctly

You can download RomRaider onto that on board computer and wire your wideband to a rear o2 sensor input. Or just wait until you have it all through the zeitronix. The RomRaider datalogging is actually pretty good

I keep hearing a lot about RomRaider, I'm going to look into it.

I'll probably just wait until I get logging correctly with zeitronix . Ill work on getting the car buttoned up a bit more this weekend instead...

I definitely spend money and work on the car more than drive it. Ratio is off.

Pretty nice build you have going. Do you have anymore info on the computer/power set-up for it? I have an older NUC that I have considered trying to integrate.

I'm using a AC to DC converter I ordered off Amazon.

Spliced, soldered, and shrink tubed the power cables from the converter directly to cigarette lighter. Converter is hidden in glove box as well as the PC adapter. I was gonna run in car UPS but realized it wasn't needed

I have a female USB cable for quick connect, flash drive, internet connection, etc... that is accessible via console

Go solid state so if you do a hard shutdown the drive isn't damaged. My unit boots up in about 3-4 seconds and is ready to log. And shuts down or sleeps in about 2-3 seconds

You can find cheaper head units with component connections. If you go this route you'll need a VGA/HDMI to component adapter and a head unit that has a resolution of at least 1024X768 or 800X600 at the very least. If you can afford a unit with an HDMI input, go for it. Worth the clarity

Awesome investment. Zeitronix is great (thanks again Butters for the recommendation). Its neat seeing the graphs and log at the same time. I'll have PSI, AFR, RPM, on a 7" display soon.

3 boost gauges total... Eboost street 2 display, analog gauge, and zeitronix data logging.

Plus I have a cool BMW roundel as background... I'll post some pics up soon

[budgetbmw3]

Thanks for the info. The boot up time and the power side is what i was most curious about. I've read about people using custom UPS/Battery/Capacitor set-ups as they said the computer's would sometimes flicker/do weird things since the signal coming in was not clean.
