Because its not that simple. How old are you? BTW who is Jarek?

What problems are you facing that makes you not want to increase boost? 32years. Jarek is the guy from MGF who makes the engine maps. Engine stock or forged?

 

[Slowagon54]

Its not only about to increase boost. You are limited by fuel, octane, knock, compressor housing size and much more. 22.5 PSI on 100oct fuel at 10° timing advance is the limit what my tuner (not Jarek) consider as a safe limit for this setup. We are about to tune the car for WMI right now. And no, it does not have to do anything with OTS maps... i am on custom tune. Engine is stock. 11:1

what is the time 100-200 on this setting?

 

[Slowagon54]

Dont know yet. Will post some results later. How about you?What car do you own?

F30, 320xi on MGF tune. Engine, turbo stock

Is that b48 or n20?

B48

 

[sqwin_n20]

turbo isnt big enough to make more power. that hybrid turbo is maxxed out. Gen 1 b46/b48 folks have a simliar sized turbo to the n209. IPOS makes a great offering for this engine if you want to push limits.

Hi sqwin, nice to see you around. I have read your comments on another forum, very informative. Yea, what Musa is doing there is just impressive. He is pushing the limits. As for IPOS... i was just a bit too fast with purchasing my Stage 2 Turbo. They have not been that well known a year ago.

hi, how is the car doing? Are there any changes? Did you take measurements of 100-200?

 

[Slowagon54]

Hi. We did quite some progress with the WMI tune. No 100-200 times yet, as we have winter conditions on the streets. Will post some news asap.

 

[cr26ik]

Hi, any news on the car? maybe new logs?

 

[Slowagon54]

Hi. WMI map finished. Car is running 230 load targets across the rpm's with decent timing of 12° max. Airflow is at 1.015kg/h which is round about 350hp at crank. Still have to do some 100-200 runs to verify the progress. I ll post all the results once done of course

Good job! Can I look at the log?

 

[Slowagon54]

Sure. Ignition peak 12°, Boost peak 23.1 PSI

 

[Slowagon54]

Torque Reqested 519,5NM peak, Load actual 244% peak and falling to 200% at redline, Mass Airflow 1011 kg/h peak

 

[Slowagon54]

Here is a log with multiple gears... started in 3rd ended in 5th. You see the issues with CP WMI Injection. Ignition is not stable due to uneven meth support. As we finished the WMI Map recently, i ll add a jug of Ethanol to mix my fuel and do another log. I expect the ignition variance to disappear. Will post more later.

BTW, Tuner said fuel and tune wise we are at an ~E20 Level of Power. AFR is at ~12 at WOT. Boost peak at this run was 23,6 PSI.

By the way, what do the parameters look like on the map without WMI?

 

[Slowagon54]

0 corrections on WOT. But its "only" 10° ign advance with 100oct fuel.
