I also don't see why that's a limitation of the stock downpipe. Why can't we run more boost on Stage 1? |

Here is my stage 2 93 log
http://www.bootmod3.net/log?id=5d6eccabc090c6521e903371 did do another 2 runs after it but it wont put them in to a chart for some reason, all i get is " generating chart for bootmod3 datalog please wait " |

here you go :
https://datazap.me/u/enemigo/f30-340...olo=1-3-4-8-10 0x4A2D is intake manifold pressure if you want before throttle it's stat_ladedruck_wert, it's 4 and 5th gears, stock downpipe. 0x4651 is WGDC %. |

I don't understand increasing boost in stage 2 with the same fuel octane, What about knock ? Usually boost is related to Octane.

higher octane - the better of course. do you know how modern ecus (ok e.g. stock tunes) compensate lower ignition timing because of worse quality fuel to get the same torque/power? yes, boosting more. modern ecus target not to boost or load, they target to torque. if IAT is low (winter) fuel quality very good- targets to less boost, if ambient temperatures are high, fuel is not perfect - targeting to higher boost, that customer would not complain that car is slow comparing to one it was in winter. stock tunes usually have pretty lots of headroom for this, when you maxx out turbo you know that your winter dragy times will be better than summer ones for sure..

yes but there's a limit on how much compensation the ECU makes, if fuel is really bad and weather very hot it will not be able to achieve the required power otherwise it will blow the engine.

most of the times it surely can compensate with stock tune. lot’s of headroom

boost limitation is based on fuel cap timing limitation is based on octane both have an efficiency range where going past the peak point will not make more power or could lose power. |

If we factor in the B58TU turbo, those can come close to putting down 525-550hp and same for tq (maybe even higher tq). I know the turbo is different, but not really sure what the difference is in terms of the compressor and turbine. I'm coming close to pulling the trigger on the BMS meth kit or the Fuel-It! CPI kit so I can max out the stock turbo. |

LOAD: Load can be thought of as the amount of air entering your engine at a certain engine speed. Load is an approximation of your motor’s torque output calculated using the the amount of airflow entering the motor, engine RPM, and a scaling constant. The amount of airflow entering the motor (measured in grams/second or pounds/minute) is measured either directly using a Mass Airflow Sensor (MAF) or calculated using a Manifold Absolute Pressure Sensor (MAP)

That's my plan, though it probably won't happen any time soon. All I want is a stock turbo e85 tune. And I'm not too enthusiastic about paying another $500-$600 for one of BM3's tuners to street tune it. Much easier to get a dyno tune and then do the street tune myself. Depending on how much I learn from threads like this and what the hpfp options look like this fall, we'll see.

What operating temp do you guys typically see? Mine has always been right at 230F .. which seems kinda high but it's about 40% up on the gauge so I figure that's where it wants to be. Oil / coolant temp both sit right around there. Still though I'm used to 210 being high on most other cars. I'd like to upgrade some of the cooling / make it kick on earlier.
The rest of my numbers at stage 1 are right there with the rest of yours. After wasting almost 3k on brakes .. I plan to go downpipe to stage 2. |

3rd gear 6.6k rpm = 233F 4th gear 6.3k rpm = 219F 5th gear 6.2k rpm = 226F So essentially it rises in 3rd gear, drops massively in 4th and slowly rises in 5th. IAT goes from 27*C (80*F) to 38*C (100*F) from start of 3rd to 5th 6300 rpm in the same run... which to be honest is amazing IMO This is MP Tune.

Here's mine. Running a custom tune by Wedge Performance on MHD. It's not fully dialed in yet.
3rd Gear Log: https://datazap.me/u/richmichael97/w...31-32-33-34-35 Fuel: E30 + Meth (50/50) Mods: - VRSF 4.5" Catless DP - Remus Axleback - Dual Resonator Delete (I don't recommend, it gets a little raspy. I plan on getting a resonator put on) - AEM V2 Meth Kit (Throttle Body Injected, 2x ProMeth 504cc Nozzles) Also here is what it runs in the 1/8th mile on this tune: |

load in my log is stat_lastwert_relativ_wert, in bootmod3 logs it is Load target (Rel.) [%].

23psi with stock turbo WHERE? yes, at 3000rpm it is possible, if you wont crash hpfp, and it is possible without crashing with additional fueling. not possible at 6000+ rpm for sure, so who needs 23psi at 3000rpm?
