I wonder what % BMW gets of Dinan sales for releasing code. And I wonder what the BMW performance flash will be like.

This is all very interesting. Key issue for me is drivability. I do not want a peaky engine. We need all of you that are going to get the Dinan flash to do us a favor: test your cars extensively, 1/4mile, 30 - 130 mph, etc. before the flash, and then repeat the tests as indentically as possible after flash.

On the M6's they had one version of the ECUs for 2006 and 2007, it used the D-CAN protocol. On certain models of the M5 it also used the D-CAN protocol.

Then some of the newer M5 used the PT-CAN protocol and Dinan couldn't program these new M5.

I believe the E90 / E92 also used PT-CAN for 2007. So I don't know if and how they changed it for 2008 for the 3er.

Any BMW Techs??

Here is a pic of the D-CAN programmer (apparently they are mechanically the same but wired differently)

BTW, if anyone wants to nominate me to TAG or Rolex as a Hand Model, please let me know.

You do have lovely hands sweetheart! (LOL)

BMW made some changes to the 2008 ECU and they will not be able to provide local software upgrade.

This means that owners of 2008 vehicles will have to have the ECU shipped to them and they will return within 24 hours.

I wonder what other changes BMW made to the 2008 ECU?????

I wonder if this has something to do with the new PROGMAN that is causing a decrease in power.

Quick question about a Dinan Flash (Never had one done). I just checked and neither of the dealers closest to me are Dinan Shops, so if I had the flash done then take my car in for whatever service it needs and the Dealer reflashes me (Which they seem to do every time I drive by the place lately), I assume that I'd have to take it back to the original location to get it reflashed for Dinan, question here is will you be charged the labor to get a reflash done? (To make it easy let's just assume that the reflash would be done at Dinan themselves since they aren't that far away).

[Dan335i]

If for any reason a BMW dealer has to remove the Dinan flash i was told by a Dinan rep that its re-done at no charge at all.Dont flame me,thats what i was told by Dinan.BTW Eric from Dinan told me that the driveability (throttle response) with there flash will be 10x better than stock.We all will just have to wait and see.

This is true about the free re-flash.

If their throttle response is 10X better than stock, I would expect a pretty big drop in fuel economy.

Much better throttle response= Leaner AFR,s

Do you really believe this?

So much shit in this thread...

cant wait to see someone get it already and run against a procede

[JEllis]

A lot of bickering in here.

I thinks its awesome there are so many choices out there. Enjoy that fact!

Wait a second, 2008 335i's have to get their ecu shipped out for the re-flash?

PROcede v2 here I come!

[Dan335i]

in my experience with ecu tuning,the better the throttle rsponse the more leaner the AFR,s were. My experience is only as a customer as my last two cars were tuned Evo,s. An 03 8 bought new,and an 06 Br350 IX bought new. I had the 8 dyno tuned by big Al (dynoflash) on Pruven Performances awd dyno at least 5 times.No problems,just re-tunes because of upgrades that i said i wasnt going to do.All the additional upgrades required the car be re-tuned.And my BR350 IX was also tuned on Buschur Racings awd dyno.So as far as tuning goes (ECU flashes and dyno tuning) i know what i,m talking about.The evo,s are maf cars,so its different than the BMW,s which dont have MAF sensor they are MAP as you know. (naturally).But talking with Al and other tuners like Dave Buschur and a few others,plus reading on the subject i have learned a lot.Everytime the cars throttle response wasnt feeling right before my re-tunes my AFR gauge would read a little rich.Which is safer to drive hard than being to lean.While waiting for my appointment to get tuned Al would tell me if its running lean keep it out of boost as much as possible and not to get on the car.But if i was rich then it was alright to still run it until i came in.Sorry for the long post,but getting to my point is that after the re-tune my throttle response was excellent and i was reading a leaner AFR. At idle it was 14.6 which is dead on.And at full throttle up to 7800 rpm,s it went from running 10.2 (rich) to 11.3-11.5,which is where it should be . So my point is the leaner the tune as long as its safe the better my throttle response and pulling power was,including mpg when driving normal.Maybe its different with the 335 because its not MAF controled,(metering the incoming air) but MAP controlled which i dont have any experience with because my Evo,s were tuned through the ECU (no stand alone)unit,but thats why i posted much better throttle response=leaner AFR,s.

I doubt anyone whos going to get the Dinan flash is getting it to compete with the procede.

Dan, tunes usually lean out an engine to improve fuel economy. To improve throttle response, some tunes exagerate the throttle input. These 2 things are independent of each other.

[5soko]

dinan will never release a tune thats lean. remember the 335i is direct injection and has alot more gee wizz factor than most cars people have tuned before and so on.

I agree with you. I was speaking of what i know from the EVO tuning.The 335 and the Evo cant be compared as far as tuning goes,or for that matter anything else.But as far as the throttle response situation and leaner AFR,s go. Like T-bone said that cars are usually leaned out to improve fuel economy. They also give you better throttle response in my experience.The Evo,s came stock running pretty rich.I forgot the exact afr,s,but once tuned leaner they ran stronger,better mpg,and much better throttle rsponse.To give an example.When i bought my 03 evo i said i was just going to do a drop in filter and get it dyno-tuned by big Al.Thats what i did.Picked up 35whp,and it was leaned out to its safest lean condition,key word SAFE. It was like driving a different car.The throttle response and overall driveability was 10x better(LOL),of course not literally but you get my point.Mpg increased,and it pulled much harder,faster and smoother right to redline.I,m 50 and have had over 30 cars in my life,with most of them being performance cars in one way or another.From muscle cars,tuners,etc.etc. including 8 motorcycles. Just about everything i owned was modified except my work car and family car.Again my point is getting to leaning out a car for better throttle response and power as long as it was at a safe lean out.I didnt want to melt any pistons.If one of my muscle cars was running rich i would lean it out by playing with jet size until it was running at its safest lean point by checking afr,s,fuel pressure,vacuum,timing,plug color,etc.,etc.The car or bikes for that matter would always run smoother,quicker,better mpg,and most important to me THROTTLE RESPONSE AND DRIVEABILITY.T-Bone also said that some tunes exagerate the throttle input to improve the throttle response.I,m not dissagreeing with him,but i think once you go slightely leaner you get better throttle input.BTW 8 months after i got my 03 Evo that i was just going to dyno tune and drop in filter, well 5k dollars later,well you know. (LOL)

[googoomas]

I'm going to have to see what the price-to-power figures are when it officially comes out and about its relationship to the BMW warrenty, BUT, that removal of the limiter is VERY int enticing.

[OC Guy]

Cool stuff for people who are worried about warranty. We'll see how it performs.

[shaunt]

Yeah, people tend to undermind the warranty.
