Sorry for all the questions, Will the msv70 be able to run the 3 stage disa ? and will he do this when i run the 330i flash from bimmerlabs without the MAF or should i have to change things in the dme settings ? |

The MSV70 will run a factory 330 tune with the three stage manifold and 255hp. That's what it was designed to do. No problems. You may end up with a powerclass missmatch between the tune flashed into your DME and your car. That's "easily" fixable. Make sure you have a good ODB Dcan cable around and BMW tools installed on a PC/laptop. You should have one for this car anyways. Hand's down the best diagnostic tools you can own. |

I guess your missing the post where i say the engine is a N52K so the last version and the msv70 is made for running the n52. The n52k should be able to run at 272 from spec, will i be able to run that or only with the msv80 ? |

All the other factory three stage N52 (3 Liter) tunes are around 255-258HP. Trust me, Several of us have dug deeply through the factory tunes to analyze the differences. We've even compared the maps between the MSV80 and MSV70, They have the same values or very similar. Valve lift, Vanos, ignition timing, torque targets are all similar. Nothing to be gained by running one DME vs the other. |

Started on the engine swap, the dme is out of the car.
The specialist says to send the current (Bosch) n46b20b dme and the Msv70 to him so he can copy the Isn from the Bosch to the Siemens msv70. This sounds so easy, is it that simple ? |

The man that will be matching the isn numbers says he only need my old dme and new dme and says if the isn in the new dme is the same as the old, the cas ews will recognize the string as the original. Is this right ? Current dme :MEV9N46L New dme : MSV70 Both the dme’s use the old style isn Last edited by Timothydevisser; 09-24-2019 at 01:59 AM.. |

I'm not well versed with the CAN ISN keys but logic would tell us that if the two DME's came from the same car/generation there is a really good chance that the keys are the same length/style. Yes, if you know where the ISN key is and have the right tools swapping the bytes onto the new DME should not be a problem. Check the ZB numbers on the CAS.
From your perspective, I would be more worried about other factors built into the DME to prevent people from installing the wrong calibration files. Powerclass is one of them and is well known. Bimmerlabs does a great job beating this protection by matching the calibration file to lower powerclass car. Its a byte value match, if your CAS has a strange value, the Bimmerlabs tune will not work. Very, Very easy to fix but could add frustration near the end of the project. Can you read the powerclass from your DME via NSCexpert? Other factors such as vehicle type, country code, cat type etc are also coded as a protection. I'm not sure that any one of them will cause issues, just suggesting that you do some research. This engine swap is not that common. Hassmachine has studied this processor in depth and has a much better understanding. |

Neither of us are as well versed in that particular DME, but I can't imagine it's too crazy to figure out where the ISN is stored.
That DME is EWS3 and not EWS4, right? |

2F44 is an EWS error.
2FA4 is a power class mismatch. I think the others are not important. You probably need to align the EWS module with the DME, and we'd need to make a tune that works with your power class. MSV70 is EWS3, so it doesn't automatically align like EWS4 does. |

You would go into the CAS in INPA. There should be an EWS/DME alignment proceedure.
The power class is in the CAS, but probably it would be easier to just make the DME ignore it completely. |

They say they did copy the isn from the old bosch module to the msv70 ( it was the short isn so easy copy ) If the isn from the bosch module is in the msv70 i should not even do the syncronisation because the cas and keys are from the bosch module so they store the same isn. Can you tell me why my key is stuck in the car ? Even when using the old original dme the key wont come out... |
