Realistically you would want to run the 91 octane (AKI) mapping for Husky 94 (RON). In short stints its probably not going to really matter but over the long haul and the health of the motor stick to the 91 mapping.

Coding that is tied to other modules (MDM, ABS, Suspension, etc) will be unaffected with the engine software. So the ones you mentioned will be retained. The only time they would be lost would be with a full factory reflash/i-level update.

FYI, we are AKI in Canada.

This was exciting until I read I have to switch maps at a dealer. I have plenty of access to 93 octane but there are times I end up in an area with only 91. Wouldn’t want to end up stranded unexpectedly... how far could you drive the car (taking it easy obviously) without having to be too concerned?
Also, whatever happened to the whole “the N55 is tapped out?” thing from Dinan themselves? How much are we affecting long term reliability? Is this really possible without even an intercooler upgrade? Last edited by Dasnub; 06-06-2020 at 11:22 AM.. |

I stand corrected. Tells you how often I travel to our neighbors in the north.
Quote:
In stock form the N55 M2 is pretty close to tapped out. 2 factors are the primary contributors to this-- the turbo and more importantly fueling. A larger turbo and intercooler will definitily help the top end and improve efficiency for some additional power, but only to a point. The car is more fueling limited then anything. Fueling with DINANTRONICS was indirectly controlled (and limited in scope) so there was little gain with a piggyback itself (stage 1) until some hardware was accompanied with it (stage 4 - turbo and intercooler). With a flash that is turned on its side a bit and we now have direct control of the fueling and are able to maximize what is already there. Getting very similar numbers without any modifications to what you saw with stage 4 previously in the process. When released, what you will see with the flash based big turbo mapping is that peak power is only minimally improved but the top end power lasts longer and will be flatter. Unfortunately it will still be fueling limited as that is simply what the pumps can handle. |

Is there any improvement in the "lag between shifts" issue seen on the 6MT? Currently being discussed here:

I’m really looking to be in the 380whp/420wtq area, to optimize my power to weight ratio for series rules. Stock was 355/382 |

Over 400 WHP you need more fuel so that would be considered "big power" on the platform in my eyes. |

Do you feel like the stage 1 tune is going to have a significant impact on longevity/reliability over stock without changing the IC and turbo as well? The tune really puts me where I’d like to be in terms of power but don’t want to do it at the expense of those things, as this is a 25k/yr daily driver. Put another way- is this stage 1 tune or full stage 4 a more reliable option? |

I agree. I wonder if they even utilized a 6MT for testing or if it was DCT. I can't imagine they wouldn't be able to replicate the issue if it was a 6MT

I was having the same (or similar ) issue, but I was shifting around 5500 at the track. This last event I shifted over 6k and never had the lag that I was experiencing previously. |
