Dinan Upgrade Report

On my 2011 E92 6 MT, ( mineral white) I just did the Dinan Free Flow Exhaust, Engine Software upgrade, and Underdrive pulley kit upgrades.
Granted I only have 600 miles on it so haven't taken it past 4500 RPM's but WOW it really feels like a different vehicle with regards to the throttle response.
Now Dinan says " Changes to the throttle mapping help soften throttle tip-in for a sportier feel and improved modulation capabilities" with regards to the Software upgrade on their website.
Anyone that has done these upgrades, which modification of the three mentioned am I sensing, because when I accelerate and shift it is a different feel than the stock M3 and this is my second E92 M3.
Of course the Dinan sound might be part of the equation, but it is really more a throttle response.
Any feedback here from others with experience would be appreciated.

I think what you're feeling is the throttle response. On a 6MT the "Power" button provides either normal or sport. Normal gives you a real gentle tip-in which is great for highway or casual driving. On the other hand, sport has a very aggressive throttle tip-in - almost jumpy - great for stoplight drag races. For performance driving (back road twisties) throttle response in normal is to slow while sport is too fast. Dinan's setup kind of puts it in between. It allows a more controlled yet responsive feel for better control to carve those corners - at least in MHO.

If you think the throttle response is quick, I guess you don't have the Competition Package. Through the M drive, you can set it to "Sport Plus" - even more responsive. Pretty ridiculous, actually. I drive in Sport off the highway most of the time, because it is just easier to rev match down shifts.

throttle response

Don't confuse power setting (wich is just a change in ratio of how far throttle moves and what % of full throttle signal is delivered) and throttle response wich can be explained as the minimization of lag between pressing the gas pedal and the car moving faster as well as the linearity of this response.

Have your Dinan mods plus intake and yes they improve throttle response by my definition.

For those with the pulley mod, what exactly are the differences your noticing? I had one guy tell me he didn't like the feel.

I have the competition package. What I don't have is i-drive. No "Sport Plus" or M drive available to me.

I was out of town and couldn't respond to these feedback's to my post. Thanks for the input.

It feels more responsive in either setting to me. ( M mode sport etc vs non M mode)

I want the air intake but it says "race only" on the Dinan site and I am worried about passing inspection in NY.

Any thoughts on the Dinan air intake upgrade?

The intake isn't race only....the mid-pipe is "race only".........Phil

In the past the intake description did not state race only at least when I got them. I initially did the pulley's, intake, exhaust and software as well. After having these mods for around 6 months I then added the middle race exhaust. Great power boost and sounds very good. I can't tell you how many times I have had compliments about the sound.

My next addition will be to change the differential to 3.62. I have driven one with it and again a very noticable change. Possible not the best if you track it alot as the high end of the stock dif is quite well balance at higher speeds.

I have zero issues and great support from my local Dinan dealer.

My thinking is probably similar to Michaelt. If the intake is now labeled as "race only", it will not be covered under the full Dinan warranty (which I would rely on for simple peace of mind). In turn, potential issues or damage (I know the chances are slim to none from just an intake) may not be covered by either the BMW warranty or the Dinan warranty. Then what?

If I'm not mistaken, the intake was NOT labeled as race only a short while ago, and it was changed to a race only product recently. I just submitted an inquiry into Dinan about this - I'll see what they say in return.

Air filters do not change or dictate your emissions.

OK, so I've received clarification from Chris McNaughton at Dinan.

My question to Dinan:
I would like to inquire as to the Dinan warranty status of the E90 M3 carbon fibre air intake. I believe this used to covered under the Dinan comprehensive warranty, but it is now listed as a racing only product. If I'm correct, was there a specific reason for this change? Were there issue with a bmw warranty? This will definitely affect my decision to add the intake to my M3 with the Dinan software. Thank you for your help.

It has nothing to do with warranty, only emissions status. It maintains our standard warranty. Only products that have a part number beginning with R are not covered under our comprehensive plan.

Regards,
Chris


So it looks everything's fine for us worrying about BMW/Dinan warranty coverage.

A freeer flowing air filter and design is going to let more reverse gases out during idle and shut down which is unburned gases stuck in the cylinders which never get expelled out the exhaust valves. So yes air filter can effect emissions or overall CO2 into the enviromenet as its CO2 that seems out hence putting a "carbon filter" on their filters for most bmw's

Not enough gases go back out when the engine shuts off to effect emissions. Thus no State by law requires the measurement of gases coming back out of intake when engine shuts off. Plus there is a butterfly that closes to keep things in or out when engine shuts off.


All emissions are measured through exhaust.

The reason that intake filter has charcoal, is so you dont have to replace it as often.

Well that is just wrong-do some reading.
Then why do auto parts stores sell engine air filters for all cars with no charcoal?

Not everything is done due to regulations since a lot is advertising and sales being able to say your CO2 level is below XYZ.
I just talked to a tech.

The main reason why filter has charcoal, is to absorb moisture during engine break in. It has nothing to do with emissions.
