MPPSK and RaceChip
2018 340i but don't fancy the whole bm3, mhd, jb4 etc tuning until the warranty expires, unless its solid 100% undetectable (haven't really read into them in depth yet)
has anyone tried running with a Racechip? Was looking at just the basic one that adds +36hp so probably hitting the 400hp mark with the MPPSK or just below. any suggestions? |

Don't do it. Look at reliable flash tunes, like bootmod3 or MHD flasher. |

JB4 and most good piggybacks are almost impossible to detect. Have you looked at the JB+? For under $200 with a 30 second install time it's literally the least expensive option and makes the same power as RaceChip and the other analog tuning boxes. They also let you trade up to a JB4 later if you decide you want a more powerful solution.

JB4 isn't detectable. Also voiding your warranty is really just a matter of how mod friendly your dealership is.
I worked at my local dealership for awhile and we used to have FBO cars come in with JB4's, MHD, Bootmod3, etc and we wouldn't void the warranty unless something happened that was obviously a result of a tune. Edit: I guess if you are really concerned about the warranty, you can go with Dinan parts and tunes. If i'm not mistaken Dinan doesn't void warranties and you can even get it directly from BMW Dealerships that are authorized to sell Dinan products. Last edited by SC_B5X; 09-04-2019 at 10:58 PM.. |

It's not that it's not detectable, it's that the techs aren't looking for that stuff when doing an oil change or brake fluid flush. They have no reason to. That's a big disclaimer/caveat.

I'm sure if they dump log data from the DME, they'd see abnormally high fuel trim numbers as well as flow rates near/at the fuel cap limit.
Piggybacks are a lot "safer" for warranty since they don't monkey with the DME, but if BMW was dealing with an engine/driveline claim, I'm sure the data they pull will point very heavily to an aftermarket piggyback. Like said above, you gotta pay to play.... |

As I've said before, they're not looking for that stuff for routine maintenance or minor warranty work. BMW will always have the means. We're saying the same thing, actually. |
