The release thread can be found at http://f80.bimmerpost.com/forums/sho....php?t=1306993

Upgrading to a further stage would just cost the difference between the stages and in this case the Heat Exchanger as well to properly run the stage 3.

Dinan_Engineering is there an update on the stage 4 setup?

You know what always struck me as odd about that statement from Dinan? Last I looked on their site the Cold Air Intake isn't 50 state legal, so they are willing to bend their rules for that one but not the big turbo kits.

Difference being that the CAI we are working on getting CARB approval for. At this exact moment there simply isn't a test to test before and after emissions on intakes using the charcoal liner. Its not that it wont pass. Its just that there is no test. Hence why EVERY single intake for the application (and M5/M6) is not emissions legal. We have been working with SEMA, CARB, and some other manufacturers for the better part of 5 years to develop a test so that it CARB can then test these types of units and give emissions certification for them.

With alternative/supplemental fueling coupled with a stage 2 turbo there is no chance it will pass an emissions test (would be too far out of acceptable limits from the original OE numbers). Very different scenarios.

This works out for my wallet not for my upgrade plan.

Dinan_Engineering why not offer a warrantied custom solution for your customers? If folks are willing to pay why not reconsider.

No offense, MacaoM3NJ , but it seems the link you cited already has your answer, which I'll paste here for convenience:

Our goal going in to the F8x big turbo project was a simple one and one we thought we could achieve without too much trouble. The goal was to create a big turbo package that garnered big power gains with basic bolt-ons and 91/93 octane, while also passing the rigors of CARB testing so it could be openly sold throughout the country. No extra or special fueling, no bench flashing… Just minimally invasive parts and installs for safe and reliable big power.

Unfortunately, after an unheard amount of tireless hours on the dyno and on the road, we’ve determined that a viable big turbo kit for the F8x M3/M4, which meets Dinan’s standards, isn’t something we’re going to make available. Without a DME flash and/or extensive hardware modifications, we weren’t able to put together a package that customers would expect from Dinan: safe, reliable, drivable and warranted power, 50 State emissions legality, at an acceptable price point. Much like the old hot rod adage you can pick 2 of the 3…

As the power levels are turned up, the car has many protection strategies to save itself from what it thinks are issues and try as we may fighting through all of them it has led us to an insurmountable brick wall. Or rather, at least no way of scaling said wall without going against our initial goals of making a product without extensive modifications to the DME mapping and/or extensive hardware modifications.

While we have solved some of the problems that have arisen the most recent issue does not have a work around without doing the aforementioned changes. Ultimately, when power is increased and boost reaches about 26 PSI, the vehicle demands a Target Lambda of .70 at the upper RPM register and creates a dangerous environment. With too much fuel, you have a high risk of your engine washing out cylinders and having a catastrophic failure. With so many different environments across the world, every car would need a special kit and most likely a custom tune based on location, environment and fuel grades. While others have worked around this problem by using alternative fuels or PI (high ethanol blends or WMI, etc) to artificially lower this cap or were able to remap the DME, these methods fly in the face of our goal and business model (distribution through dealerships, emissions legal, having a factory matching new car warranty being viable, cost effective, long term safety, etc).

We apologize to the customers that were anxiously awaiting this upgrade, but when we make a product available, we want to make something that not only represents Dinan well, but also protects our customer’s vehicle reliability.

I read it... what does this mean to you?

To me, it means the cost of doing it "right" by the standards of Dinan and Driven Performance Brands would introduce a wall of R&D overhead that would command an unrealistic, astronomical price point, and that such an endeavor doesn't match the company's objectives.

[MacaoM3NJ]

You're right. Have a good one.
