Here's a log of my basemap for my Pure 800, i'm doing a 93 octane tune first and then i'll do a E30/E40 map.

(There is a 3rd and 4th gear log)

Looks great! How does it feel?

Love the 83% waste gate duty cycle for 20 PSI at 6800 RPM

Spool looks pretty good, WOT at 2950 RPM and target boost by 3300 RPM, similar to stock.

Interesting that they are targeting AFR of 12.0 by 6500 RPM HPFP rail pressure is bang on target.

Spool is definitely noticeably slower than stock, although idk if that will change with more revisions or not, but it's not bad at all. I've noticed from my logs it spools by 3100-3400 which is still VERY good.

The top end pulls like a fucking freight train and I love it. I raced a hellcat earlier tonight and gapped it from a dig, he spun, but when he caught traction I was still pulling hard on him. I finally let off around 150.

Nice. When do you think you'll do the E30/E40 tune?

Probably within the next week. Just wanted to get a 93oct tune done so I actually had one for when I go out of state.

Curious when you will hit the fuel limits. Juan got up to ~630whp on the spool pump.

Quite a few timing pulls in there from the looks of it.



Other than that, how's the car feel? Also what HPFP are you running?

I also noticed the timing wasn't great.

Not my car, that was the log that was posted for another M140i the other day (Dorch Stage 2) I managed to download the log before all related posts were deleted.

I'm gonna go ahead and copy my post from B58 Enthusiast on Facebook over to here to see if I can get any answers.

Anyone know what else could be causing these timing corrections? I just replaced plugs (NGK 94201) and they're all gapped to 0.022" and i'm on E40 mix (tested the E content to make sure it was perfect). It's still pulling timing for some reason (it doesn't seem to be knock related).

Mod List:

Pure 800 w/ High Flow Inlet
Williams Performance Intake Pipe
AFE Drop In Filter w/ Stock Airbox
Dorch Stage 1 HPFP
VRSF 4.5" Catless DP
Resonator Delete w/ Remus Axleback

(There is 3 datalogs in this upload, 2 3rd Gear Logs and 1 4th Gear Log)

First and last one look better than the second one. Nothing stands out, fuel pressure is good, AFR is good. This isn't at your stock turbo level yet for torque and power. The target timing appears low for E40.

Have you pulled the plugs to see how they look? Cylinder 1 - 3 appear to be the laggards.

So I turned off DSC to log (even though I wasn't spinning) and the corrections completely disappeared. Got a revision today and we turned up the boost a bit as well as increased timing.

Looking good. Interesting about DSC.

I created a 340i car profile for Virtual Dyno and here's an output based on your 4th gear run. If you can get a 4th gear 100% accelerator from about 2500RPM it'd be good. This one only went 100% from about 3600 RPM. Looks like about 520 whp and 640Nm. Better than stock turbo now!

As the Dorch Stage 1 looks maxed out at that boost level with E40, what about going back to E30 and shoot for 18 PSI up to 4500, then 20 PSI by 5000 RPM, 22 PSI by 6000 and up to 24 PSI up top?

Why does everyone talk about targeting boost with our ECU logic being load based? Boost will vary a lot, because 22psi on a cold morning below sea level is very different from 22psi in a desert hot environment high up in the mountains from a turbo performance perspective.

It's a free Windows PC based program https://barnhill.bitbucket.io/

There are quite a few videos and tutorials if you Google it.

The key to using it is always doing your testing on a known flat section of road, then you can compare log for log to see changes, improvements etc.

You need to go into Car Editor and create a custom car as the default ones only go up to 335i, no 340i.

For 340i Auto I created a custom car with these variables:

Weight 3640 lbs
Drag Coefficient 0.29
Frontal Area 23.68 ft2
Tire Diameter 26.03 inches

Gearing
1 5.0
2 3.2
3 2.143
4 1.72
5 1.314
6 1.0
Final Gear Ratio 2.813

In the csv file that you load you only need column heading Time, RPM and TPS to get a dyno with power and torque.

If you also want AFR and Boost add those too. The column headings must be exactly as listed above unless you go into settings and assign custom column names.

TPS is throttle position sensor and for a valid log this must have values of 100 for each of the rows in the data log. I just open the data log in Excel and copy/paste the 100% accelerator rows.

After you load the data you select the gear that was used for the run and add passenger(s) weight. In options you can choose Dyno type and HP or KW and lb/ft or Nm. I've found DynoJet to be good to use.

Your tune might vary from someone that's tuned in a different climate, but boost on the same tune doesn't vary that much. Maybe +/- 1 psi going from summer to winter here.

The biggest contributor to load is the MAF values and that has a correlation to boost. You can adjust the load profile however you want but MAF readings and boost for the same turbo will be consistent. So we talk with what makes sense in these scenarios. Because at the end of the day, "175% load" doesn't translate to anything useful in discussion.

My garage queen is a Mazda 3 MPS (Mazdaspeed3), tuned by myself. ECU logic is the same - targeting load which is calculated from MAF voltage that is translated to g/s. ECU automatically adjusts boost within specified limits to 20-22psi at 0°C IAT and 29psi+ at 30°C IAT to reach my target load.

I will log my M240i during summer heat to get the baseline for boost values in different conditions. Got her in November, so there are no high IAT runs yet.

My GLI is the same, but boost targets are dialed in because MAF values and IATs don't vary enough to warrant an extra 40% increase in boost pressure, even with a garrett turbo. Cold air intake + big IC keeps everything in check. The B58 is even better because of the air to water IC.

And like I said, you can adjust parameters wtihin the scalling yourself. So My 150% load won't necessarily match yours in output. Easier to talk boost since it's consistent. It just doesn't mean we're making the same power with the same tune. That's one of the ways BM3 originally got around the torque limitations of the 8AT.

Definitely run logs, it'll tell you everything.

Some new logs running the Wedge Rev 2 E50 map. Boost seems nice and consistent, close to target. Any concerns with these cylinder timing corrections?

Seems weird that it's showing timing corrections on cylinders that have timing consistent with all the others. I wouldn't worry too much about it, but it wouldn't hurt to check your gap. I've seen some people run tighter gaps as ethanol content increases. Maybe go down by 0.002"?

Actually had new NGK 94201 plugs installed right before I did the pump and tune. Had them gapped to 0.022 by 'my guy', friend of mine that is a professional mechanic and does all the work on the car. (Except for the pump, I installed that all by myself! )
I don't think I'd want to go narrower than that, do you?
