Questions on Dinan Stage 1 vs Dinan + Performance Engine Software
What is the difference between the Dinan+, Dinan+HE, and Stage 1 Software for the BMW M2 Comp. PS I have a 2020. It's already been bench tested to confirm my installer could upgrade it.
Is the Dinan+, just stage 1 with a warranty and hence not as agressive? Does the Dinan+HE version come with the heat exchanger, or is it extra and you need the +HE version to allow the bigger gains? Would the best combo for track use be the Dinan+HE sw, a heat exchanger, plus the axle back exhaust? PS: My car is a lease, is it easy to reflash the production SW at turn in? Also, does the Dinan Coil Over system come with camber plates and adjustable for track use?

Tune Differences/Notes:
Performance: Dinan+HE and heat exchanger are the most important power mods. The exhaust is great but for all intents and purposes its a sound only modification. The intake is similar and while it does give you a bit of power up top which can be beneficial at the track its mainly a beauty piece that also improves the throttle response. You will get much more use out of the track from a couple of the suspension mods before the latter engine modifications. Monoballs, swaybars, coil-over (HAS kit) or links will all probably give you more tactile improvement. Especially at the track. Coil-Over: The coil-over does not come with camber plates. In reality its a height adjustable spring set. The factory dampers are very good so adding cost for a full coil over with new electronic dampers never seemed worthwhile for the vast majority of the consumer base. For full coil overs if you wanted to go that route there are plenty of options though (KW, Bilstein, Tractive, Ohlins, etc.). The biggest difference for our kit is we use linear springs instead of a progressive one. This allows for a more predictable suspension travel and what most feel is a more compliant ride compared to other options (including stock). If you have any other questions feel free to ask them here, DM me, or contact the sales team by phone. |

Can you please expand on the Dinan Limited Warranty Exclusions In particular the part that reads "any vehicle operated in any competitive event or subjected to aggressive track conditions" Would non-competitive track days or HPDEs be considered aggressive track conditions? For example, if I got a Dinan+ tune and took my car to a typical track day on a road course in which I am neither competing with or timing my vehicle would the warranty remain in effect? |

In any case, I don't think I've come across any independent dynos on the Dinan tunes You can find some dyno comparisons from Dinan here https://f87.bimmerpost.com/forums/sh...ighlight=dinan And also on the Dinan website |

Unbiased dynos to debunk some Of the claims that dinan tunes are way underpowered And essentially “pointless”. |

You can surely do a crank hub fix if desired for peace of mind / preventative maintenance but it is not required. To my knowledge warranty/tech support have only seen two S55 hub failures over the years when Dinan tuning was present. Both of those were as a result of a money shift however.
