BM3 OTS E30 dyno
Got the car on the dyno today to check out the off the shelf BM3 e30 map.
Car is a 2017 M140i, manual gearbox. Engine mods -BCS 100 cell catted downpipe -K&N Drop in Filter with hot climate intake duct -NGK spark plugs gapped down to 0.022” Fuel is ~30% ethanol mixed with 98 ron. Tune is BM3 OTS E30 stage 2 Car has been on this dyno twice before. Visit 1 car was completely stock including stock downpipe. Stock: 307whp Mission Performance Stage 2 tune: 391whp Visit 2 was after the down pipe was installed. MP stage 2 with DP: 401whp Visit 3 was today BM3 e30 tune: 426whp Log: http://www.bootmod3.net/log?id=5d1ebc93ae729b16a305fe38 Runs today and visit 2 were done in 5th gear. Unfortunately the runs on visit 1 were done in 4th gear so the graphs don’t overlay nicely. I’ve overlayed the MP stage 2 tune (98ron) for comparison. BM3 made 25 hp more on lower boost (MP:22psi, BM3:16psi) and held power better to redline. Happy with that. Last edited by Nugget; 10-21-2019 at 02:37 AM.. |

So MP was on 93 and BM3 was E30?

Yeah you probably wouldn't be willing but would definitely be cool to see if e30 on MP would make a difference.
Happy you're happy OP Thanks for the comparison

It's not hard to switch flashes. But probably not going to make time and pay for another dyno. I'm very happy with the whole BM3 platform.

Thank you, just wanted to know if it was an apples to apples comparison or not. Thanks!

I think a BM3 93 dyno would be good to see!

It will be fine.
These cars are sold in Brazil which has a minimum of 25% ethanol in their fuel. |

It says that but it isn't.
It's because I flashed using my phone and took the log using a laptop. Apparently the ODB agent labels the log according the last flash it did, and the Stage 2 93 was the last one done using the laptop. |

Just made the switch to BM3 Stg 2 E30 OTS and xHP stg 3.
Here are my logs: http://www.bootmod3.net/log?id=5d439d8bc090c61b5d42b44b http://www.bootmod3.net/log?id=5d439ddcc090c61b5d42b44f |

Do you know why it spikes like that or is that just how the OTS map was developed? Trying not to have throttle closure issues like that. What can I do to remedy it?

Yours just spiked really high, like 4+ over request. Mine is typically 1-2. I don't feel the throttle closure because boost just dials back a bit. Do you feel anything when driving/doing the logs? |
