Ok but that's compared to MPPSK.

On another note I also find that the M340i IAT quite high relative to the ambient temp in Ukraine of 25 Celsius at day and 15 at night.

Just picked up 110 gallons of ~E33 mix I made the other day so I can have it on hand instead of random fillups from small cans. Gotta say, I'm happy with this pull

2019 X3 M40i
ER catted DP
MST intake
VRSF charge pipe
BM3 Stage 2 E30 with ~e33 fuel

4th gear pull - traffic prevented a 5th, and now its raining tonight

Where in Ukraine? I’m from Odessa

You are welcome mate it's nice to see B58 Gen2 logs and compare it to Gen1, I actually asked if anybody has logs in the M340i Forum and they didn't have any idea what I was talking about

Also if you got a Dragy and did some runs you can post them in this thread: https://f30.bimmerpost.com/forums/sh....php?t=1621233

I am also have a problem with IAT.
Amb. temp. 22C (at night), IAT at the 24PSI 55C

M240IX Pure800, Dorch Stage2...

[IMS-340C]

24 PSI is a lot of boost, check your charge air temp it would definitely be very high.

Here's the log from a 7.02s 100 - 200 run using the MHD Stage2+HPFP and E42 fuel, Dorch Stage 2 HPFP.

Tiny bit of timing delta for knock adapt and minor corrections.

Certainly goes well and Virtual Dyno says 509 WHP

60 - 130 mph was 8.25s

Morning all. Reading through all the pages it seems that us chaps in the UK who don’t have access to e85 are using boostane professional. Is this safe for our engines I am thinking of getting some to take our 99 Ron (us 94) to 101Ron (us 96) just to help with timing etc when running the 93 tune.

[Devil doc]

Hey, do you guys mind taking at peak at my log. This is the OTS stage 2 93oct hmd map. I do plan to get a tune soon, but I just wanted to get a feel for how the car is running as of now. Thanks

[Torinalth]

I've been slightly concerned with the amount of whooshing I'm hearing from the front of the car under part load, and got a 5th gear log finally on my e30 map and noticed the MAP is not keeping pace with boost target or pre throttle. Suggesting leak?

Yeah our DMEs are really damn smart, that just makes it so much harder to really know what's going on. It also makes the car very, VERY consistent with the stock tune where there is plenty of room to make timing and boost corrections based on fuel and conditions, but that also means that when the car is tuned and running much closer to the limits, performance is not always consistent. I can notice a HUGE difference between 24 and 35C ambient temps that isn't there with the stock map.

Did again some logging this weekend. My timings are still not ''in line'' on all 6 cylinders. Only on the stock tune.

I ran the ACN 91 map for a while. Timings aren't so different from the 91 or 93 maps, the car is only much slower but the exhaust burbles are much louder ?!

I have no idea how people get that timing correct.

Maybe I need another car lol

(Also I have a strange whining noise coming from the back at higher speeds, I don't hope it's in my xdrive drivetrain

I've decided to stop switching maps and taking dozens of logs for a while. I'm getting the feeling we're not letting the ECU adapt and all that pulling of timing is part of it. I flashed the 98 stg1 map a couple of days ago, I'm gonna use up the whole Q8 tank driving like I generally do, which is a mixture of normal, calm driving when I'm with my wife and like a redline shifting maniac when I'm alone, then fill up at Shell, use up THAT tank and then take some logs when it's almost empty. I'll report back with my findings.

[Sgm123]

Just filled up with momentum 99 and car seems to be running smoother than with V power. Going to give it 100mile to adapt then log

From what I've seen Boostane doesn't do much, or you have to use a lot more than recommended to get timing improvements, in which case buying bioethanol or a drum of E85 would be more cost effective.

Spark plugs may need to be replaced more regularly with continuous Boostane use also.

Looks OK, could do with better fuel, more octane or addition of some ethanol.

Getting up to 11 - 14 degrees of timing over 6000 RPM, just could be a bit better and more even between cylinders.

The log looks good, nothing to suggest an issue.

MAP (TMAP at manifold) and Boost Pre-throttle use separate sensors and are scaled differently as one is 2.5 bar and the other 3.5 bar. Up to about 0.6 PSI difference is normal.

[Sgm123]

Thanks. How much e85 is required to make an improvement I can get 19l drums of renegade pro e85 for £60. If I could get away with 6.3 litres to a tank so it lasts three tanks that would be feasible. Fuel here comes regulated to e5 so by my calc I would end up with roughly e13.5 including the base e5. Is that enough to help with corrections etc.

Here in the UK sadly doing or trying any EXX maps is going to be expensive

[Sgm123]

I don’t want to go to an e85 specific map just help improve corrections on a 93 tune. My last logs on v power timing was all over the place just filled up with momentum 99 today see if that helps but if 1.5gals of e85 will help do what I need I will buy some. Only works out an extra tenner a tank of the 6.3 litres will be enough. Much more than that and you are right things get very expensive.

Hi,

Looking for feedback on my log.
2016 340xi
AA catted downpipe stage 2 91
I have “not high grade” 93 octane.
I was running stage 1 93, but noticed some knock detects, so I swapped in 91 tune for stage 2, but still see knocks.
I’m still trying to learn the logs. I think the timing doesn’t look great? Maybe new plugs would help? Should I run the colder/gapped ones I see comments about? I have 40k on the odo.
Thanks!

Adding 6.3l of Renegade E85 to 53 of E5 (for F30 with 60L tank) will give you E13 or E15 for the smaller F20/21/22 tank.

It'll clean up your timing on a 93 octane map, make more power and may even go OK with the 102RON/95 octane maps, as the base fuel for the Renegade product is a higher spec petroleum, so overall octane will be 94 - 95.

Let us know how it goes if you try it.

Im going to gap my spark plugs and run a little bit of E for my f22, because my car is not happy with the mhd ots maps. I tried both the 91 and 93 maps and got similar results, so I reflashed the stock map again, and while it’s much better, it’s still pulling timing.
