Me too! The tune with heat exchanger and exhaust combo is my current fantasy combination.

Have you tested in places besides Alabama?

I feel an intercooler is a decision best left to the consumer. If I notice heat soak, then I can upgrade the intercooler. I am from Texas, currently live in New England. I am skeptical that I will benefit, especially since I don't track my car. "One glory run" pretty much describes my driving.

Dinan has sold tunes with a warranty and without an intercooler in the past. I can understand not providing a warranty with new e85 and 100 Octane offerings. I can't understand why I can't have a 93 tune without an intercooler and with a warranty.

As a consumer these changes in policy make me feel like the products of old offered more value than your current products. That's not good for your brand.

Yes, there are test cars around the country in various environmental conditions. A multi-gear pull in all environments has the same derating issue when the car is pushed beyond a certain power threshold.

That said, there is still an option for a warrantied tune without the heat exchanger (Dinan +). It simply does not push the car past that limit of derating however. For those that want to get more, without the clear limiting factor of charge cooling, can have it with a slightly higher state of tune that is warranted with the heat exchanger (Dinan +HE). There are 2 warranted options. If you elect the one that does not require any hard parts and at a later date you want to upgrade to the HE variant for more power you can do so and there would be no charge from Dinan either.

Keep in mind the warranted tune that does not require hard parts is practically identical in power gains to the stage 1 DINANTRONICS for the S55 so the "value" of its predecessor is the same. One could argue quite effectively the value of the flash is superior since it controls more variables for a more robust tune, eliminates the governor, and has the possibility of adjusting to multiple octanes should one choose to do so as well (albeit sacrificing the factory matching warranty coverage in the process).

We also still have the DINANTRONICS variant of tuning in the fold if one wishes to go that route as well. If anything, Dinan is providing a much more robust catalog of choices then it has in the past since the brand has never offered a non-warranted option or offered multiple octane choices, etc.

When is the official release?

Does the Dinan Stage 1 tune eliminate the overrun pops and burbles created by the factory tune?

No.

Was pretty pumped about this until I realized the +HE tune is $1800 lol

For the factory matching warranty version that is correct. The "non-warranty" version is significantly less however.

[SinisterC6]

Intrested.

How does this tune feel on the top end, I feel like power cuts off on the OEM tune above 5500rpm

How will the warranty work, say if a crank pulley slips

The power graphs in the first post will give you an idea of what to expect as far as where power comes in and where it drops. It basically mirrors the stock curve so at 5500 RPM you will start to see some drop. The difference however is you have significantly more power accumulated at that point with the tune and the degradation is about the same ratio as stock so it will feel much meatier.

Warranty is the same as it has always been. We match the factory new car warranty 4yr/50k so if BMW denies a claim due to a Dinan part we would step in and cover the claim assuming the appropriate tune is in place (warranted variant) and being run under appropriate conditions (+HE is run with a HE actually installed). Just like BMW we would not cover what would be considered negligence, such as a money shift that may cause a crank hub failure, etc.

What if one has factory warranty extended? For ex, if the car is 2 years old when installing the Dinan tune, and the car got an extra 3 years warranty from BMW (7 years total), does one get 2 or 4 years with Dinan warranty?

Dinan does not match CPO or extended warranties. Just the factory new car warranty. Extended and CPO warranties are treated completely different in the legal system and don't have the protections (for both the end consumer and us) the new car warranty does.

Thanks for confirming. Then there's almost no point for getting the Dinan warranty if the car had been driven more than a year

If you drive 20k miles a year I can see the value greatly diminished but if you drive the car 6-10k miles a year then I think the value is still retained. There's always the non-warranty version as well if the cost is deemed to high for the peace of mind.

might have missed this question but is removing the DME and sending it to Dinan included in the price if done at an authorized dealer or can we drive to Dinan and have it done there included with the price of the tune?

I'm hoping the authorized dealers can tap into the ECU directly...

[ChrisRoman]

I hope so. One of their premier authorized dealers is an actual BMW dealer about an hour away from me that I wouldn't mind going to if they would tap into the DME and install the Warrantied tune at the listed price or maybe even drive up to Alabama if Dinan would unlock the DME and install the tune for the listed price

If the DME needs to be unlocked/backdated the ECU would need to be sent in to Dinan to have that process done. There is currently no tools in the field for that to be accomplished at each individual dealer. Being worked on, but I don't see that being available in the near term.

As far as shipping charges go -- if you are upgrading from a DINANTRONICS unit then shipping would be covered by Dinan. On a new install however, the shipping charges would be the responsibility of the dealer/customer.

The gains per the Flash Guide show max gains of 80whp and 80wtq with the Dinan+He. The dyno graphs do not represent this...am I missing something?

I am very interested in the Dinan+HE which I will run with 93 octane fuel and want to confirm what type of gains I will see.

The chart in the original post for the Dinan +HE tune shows max gains of 80 HP @ 5500 RPM and 88 lb-ft of torque @ 4500 RPM for the S55 M2C. What are you seeing?
