Best FREE Mod - Update Your DME E46 330ci

[@mikolizazi]

I really enjoy your videos. Fun and no nonsense at the same time 😂😂

[@OEMplusRESTO]

Thats a very nice compliment. Thanks

[@patrykweglowski8229]

My new favourite channel to watch, you've got alot of great tips and comparisons ,Oem+ is exactly the way I'm going with my 330ci as well. If you ever go as far as trying to achieve some NA power from the M54 I'd love to see you take on an N54b30 intake manifold swap, theres limited info out there but its supposed to give some considerable gains of around 30-40bhp

[@OEMplusRESTO]

Thank you. Id love to try and do that, and add zhp cams while doing it:)

[@shaDOwwwRI]

Ok, I did that. Thank you so much for your feedback and input trough your video! The difference on my M54B30 running MS43 it's really noticable. I'm running the sprint booster on my throttle pedal so it's not just the "butt dyno" effect after resetting the adaptations. Insane what a great mod! Thumb up again for the video with the data!

[@renas5371]

I always run 99 ron on mine as there’s noticeable difference in throttle response, engine feels more lively in general, plus fuel consumption is noticeably lower too. Around here tesco momentum is more consistent than vpower so is recommended by tuners.

[@DaSixSixOne]

Discovered your channel earlier today and very happy I did. Great video and information. Thanks!

You've inspired me to try the software updates, thank you! :) I did the ZF auto gearbox last night, and after a bit of a worrying time waiting for the faults to clear it's all good and certainly feels better and less prone to changing around. My MS43 DME is next! Thanks again for your video, it was very helpful! I've only had my E46 325Ci for a few weeks and fixing quite a few mechanical issues with it too, so it's good to be able to fix/update the software as well. Cheers!!

[@OEMplusRESTO]

Thank you for the kind words. Im glad to hear you got the trans sorted. Please let me know if you feel any cahnge after having updated the dme as well. I certainly can feel the difference now but i also switched to premium fuel for this last part of the test.

[@kwaki82]

Great vid, all explained and meticulous. Incredible results!

[@maczurek]

that's actually pretty impressive, very instructive video, thanks for that😉

[@OEMplusRESTO]

Yes i believe so too. Quite surprised just how big difference there is

[@mariuszanfir5970]

While I cannot comment about the software update making a difference performance wise (though it would make sense to have further optimizations), I can confirm that there is a difference between the RON rating simply by looking in the ignition timing maps in the DME -> there are two of them, one for 95, one for 99. And, as expected, the 99 one has slightly more aggressive timing. So, people saying that the engine runs the same with either fuel are simply wrong. Even if you don't necessarily feel that difference, the DME adjusts ignition parameters differently.

[@OEMplusRESTO]

Super cool to have someone verify it with facts. Thanks

[@TheEdyi]

0.2s is hard to notice but the 0.4s is noticeable imo. I hope you do. Then maybe you can give me a few tips as im not the best with tuning modern cars. Carbs and dizzy’s however🤣 Thank you for the support💪

[@tiitsaul9036]

Thank you. I love your scientific approach to car tuning. This is how it's done! I wish more people would follow your example instead of trusting butt dyno. Are you going to attempt adjusting ignition table manually? There maybe couple of degrees timing hidden in the safety margin.

[@OEMplusRESTO]

Im on my second or third week waiting for a mail order tuned dme to be released by customs so i can try that out instead😅 and thanks for the support💪

[@E90M3ZCPS65]

Thanks again for the excellent information and hard work. Going to try this next week. I need to see where to find the files. I keep missing that part.

[@OEMplusRESTO]

The updated files are part of the download. The youtube video i link to in the description has the link to the tools you download. If you follow that videos guideline(install the tools) then they are part of it. This part is what confused me as well before downloading the tools(with the updates included) as i already had winkfp before but when i tried using the version i already had it wouldnt show me a possible update to my existing tune. But once i installed his tool(winkfp and inpa) i could do the updtate. Its really easy to do so once you follow the video i linked to in the description

[@OEMplusRESTO]

I should have explained it better and i did try and make a video of “how to” but it didnt come out all thay great due to poor camera and poor skills on my part. But if i can do this update so can everyone else

[@E90M3ZCPS65]

Tim thank you always!

[@E90M3ZCPS65]

Tim is this update only for MS43? I have a MS45.1 and my hw file is 7561520. No update file will show up. I must be doing something wrong.

[@OEMplusRESTO]

@@E90M3ZCPS65 did you follow the videos step og replacing some folders with others? But yes there should be ms45 as well, although that should take considerably longer to update once you do

[@kennytmt]

Awesome video.. Thank you!!..

[@ivanfilipovic3296]

my 330ci was produced in may 2000, it came as euro 2 car, in car registration papers it's listed as 172kw car, while normal ones are 170, and US spec are 168kw. drove euro 2 and 3 car, butt dyno felt as euro 2 was bit more peppy and eager to go, but in this realm it's too easy to get some false positives. Also long time ago car served me extremely well so i decided to reward it with some Shell premium fuel and car ran like shit, loss of power and idled bad. no obd2 codes and couldn't find problems, but when i used all my expensive fuel and went back to cheap one car ran great again.

[@OEMplusRESTO]

Interesting. Thanks for sharing

[@northernmaten7676]

thats weird to have 172kw with euro 2 tune, can you provide the vin number so we can check it on bmw decoder?

[@ivanfilipovic3296]

@@northernmaten7676 WBABN51000JT60608, i check and it says on 170 on decoder, actually it is june 2000 not may. I didn't get any books with car so my resources are limited. Only thing i saw diffrent parts wise from euro 3 cars is that i had door handles which don't go up, just straight out (99-00), i have strut towers in shape of e36 ones (same as m52 323 and 328), and i have yellow steering rack 712 (as zhp). All euro 3 i had seen have purple tag rack, euro 2 i saw for most part had yellow zhp rack. Car was bought and first registered in croatia and as far i can track past back it was always listed as 172 kw

[@budrobadre]

I tried filling up my daily driver with one of those gas canisters too last week and made a complete mess like you lol. A friend showed me you can buy an electric siphon pump for this exact purpose for like 20 euros. I'm gonna get one for sure. Anyways, great video like always! Might try this on my 330 after the engine revision. I think the previous owner put a custom tune on the car tho, I wonder if that will cause any issues.

[@OEMplusRESTO]

I always struggle with pouring fuel on manually lol. Thank you for the tip:) I dont know how to find out if its tuned or not, or how well it was done. But i have shown here that bmw’s latest tune for the m54b30 is super consistent and also adjusts well to fuel quality. So maybe you could do the same test as i did and see if you get the same results? If not, its either a poor tune or no tune at all.

[@devacds]

But how do you know wich dme family to select for your car?

[@skyward3107]

Very interesting, I am wondering though if this is because in doing this you are resetting the throttle adaptations? I know on the non M E46's, the throttle adapts itself to your driving style. Over time, with enough combinations of hard/gentle driving, the throttle is no longer at a 1/1 ratio. The only way to get it back (temporarily, without a tune) is to reset the throttle adaptations. Most owners I've met notice a very big difference after doing this, although it only lasts a few days until the adaptations change again. I would like to know if after a few weeks you still notice these faster times

[@OEMplusRESTO]

Thats a very good question. Is it just adaptions? Well. I dont know! The only thing i know is that i give it full throttle for the test. So unless adapted full throttle isnt full throttle really, the results SHOULD be the same. But again. I havent actually tested it. But during 10-15 runs to get the 10 verfied runs it didnt seem to get slower What do you think? Is the full throttle perhaps not really full throttle after a while?

[@skyward3107]

@@OEMplusRESTO Thanks for coming back. I think the best answer is - time will tell. I know the throttle adaptations are fairly slow to change especially when you have only just reset them. See how it is after a months time :) By the way - I've only just come across your channel - great content! Fellow E46 owner here who loves working on M54's

[@OEMplusRESTO]

@@skyward3107 thanks so much. And its a great question. Im in the middle of a front end refresh, but i have ordered a mail order tune(just a tuned plug and play dme) and will try and do more testing (oe vs mailorder) and possibly throw some intakes in there and maybe even UD pulleys as well. So yws howpfully time will tell:)

[@oncall3570]

@@OEMplusRESTO I understood the adaptations to include variances in fuel octane, and that they take '500km' to update, so changing from 95 to 98 takes a tank or so before the adaptations result in an ideal map, according to the ECU and its sensors. Not that this stops a change being measurable after draining and replacing as you did it, but that the change may be better (or worse?) by the time the tank depletes. The throttle adaptations can be modified along with the hexvalues in the maps now thankfully, which is what changes the feel of the car's 'pokiness'/responsiveness, the most. These are different on Auto vs manual, as well as octane, and likely, emissions (dep. on market and production date). I wonder what the one you flashed was for!

[@wot48320]

Great video, I was just about to do the same on my e46. If I understand correctly, you have to update the DME version one by one up to the latest version, did you hook up external power to the battery during the update?

[@OEMplusRESTO]

Hi. Not one by one no. In short, you “just” launch winkfp and choose your DME. Then it will itself find the latest tune made by bmw for it, and update it, if you choose so. But it does that 2 times before its done. The 2 times you see it loading 0-100% is normal and requiered. Its probably the full and partial binary it uploads to the dme but this is just a guess

[@OEMplusRESTO]

Yes hooked up to a battery tender

[@daz6437]

Do you think the drop in temperature as the day progresses during your test would account for some portion of these results?

[@OEMplusRESTO]

Good question. It does matter. But the 3degrees celcius difference wont make that big of an effect on its own. Especially not when neither temp is in the high temp area like 30degrees celcius would be. Also, i have to work with what ive got and weather is one thing i cant control:(
