Japan Spec 240E software flash by Alex@Alpine

Alex is great. Have the euro mdm and dct software. 👌👍👏

[xchosun1x]

Got this tune from Alex recently. Dct shifting is great and the engine response is very noticeable. Thanks Alex!!!

Very interesting !

What is the technical difference in the Jspec tune? Is there any minimum fuel requirements? Wondering how much of a difference there is with the valve timing, fuel, timing, afr, etc. Any more feedback on this tune?

It's not a tune, it is factory SW, min requirement of 91octane.

So it works with all factory thresholds just as the US spec 240e? What is the main differences? Is there power level increases or is it better drivability. Trying to determine the key differences and what is actually changed in the Jspec software to achieve the results.

It is a very noticeable power increase, it has been a long argument between many for sometime now.

I have done this for many customers, and they are all very happy, it is very responsive, almost makes the car feel lighter.

I do not charge anything extra, if you come down for a DME update to lets say 240E, you can opt to update to 240E US, Euro, Chinese (same as Euro,) or Japanese.

Hope that helps.

Is there any perceived difference between Euro 240E and JSpec 240E?

Japanese runs more aggressive IMO.

Hi Alex I have sent you a PM yesterday. Looking forward to your reply, thanks!

[BMW Fanatic]

Alex, how much do you charge for Euro MDM, JSpec 240E and GTS DCT software? Also, are there any other tuning/coding upgrades you offer that might not be widely talked about? PM me. Thanks! BTW I am in Canada.

Would the jspec or euro 240e pass a smog check in california?

[Longwong]

Wait there is a Japanese version making more power?

[Sales@Evolve]

First we had everyone thinking 240E made more power than previous versions

All that was happening was the adaptions were being reset and the cars were running higher ignition timing..... for a while.

This is something we have been testing since these cars were released and flashing was available. We have the ability to analyse all of the maps and compare to different versions.

The Japan spec file has the same ignition and AFR targets. It has the exact same knock detection parameters.

[Longwong]

Thanks Sal-that is what I expect from someone actually who is selling or giving this software to people. To know the objective differences and not just a software that feels different. Its SO easy to log data like timing etc, that if I were to offer someone software than I would tell them the objective data points that make it better. Thanks for clearing up. I just could not see bmw designing a tune for euro or japan from an increased power perspective

oh man, i wish I read this back in May when you posted. There is a local guy here in DC Metro area that did my 240E update and he headed out to the ALMS race at Laguna Seca in the spring. He had some kind of event out in San Jose where he updated a few cars with 240E, I believe he partnered with someone locally in the Bay Area...pm me if you're still interested and I can connect you. I'm not affliated with him other than I was just a past customer (not taking referral money or anything)...but I think there's a local guy there that can do it.

I was charged with less than $100 for just a 240E coding (I can't remember exactly how much), but you can also get feature coding done too with a-la-carte pricing (Euro MDM, idrive startup warning, 1/8 gas warning, amber-clear turn, door unlock features, etc.)

[mdosu]

Well all this confirmed my observations that the 240E gives you a slight fuel consumption improvement. On highways, I got a bump of 2-3 mpgs after my update. I use to have 70E being a March (or was it April?) 2008 build. It makes sense that leaning out the mixture would create this result.

It's also interesting that someone reported the Japan and Euro 240E didn't pass emissions. I'd like to get to the reasons behind that. I would think at least all 240Es have similar timing, so I don't see why emissions would be effected.

I also observed smoother partial throttle & low RPM engagement, and it makes low speed driving in parking lots and traffic much easier.

I did not observe any WOT or power delivery differences as some has stated. I attribute all that to butt-dyno differences...or perhaps there were other moving parts like getting Euro DCT coded with the 240E update. It may give the perception of quicker acceleration.

Overall, it's the best <$100 I ever spent on this car.

Actually, BMW has done this a lot, cars in different regions having more aggressive software VS other regions, I'm sure Sal could tell you that. Same with the transmission files from different regions, traction control and so on.

I am not here offering a remap, tune, or non OEM Software, I am merely offering this as a option for customers who come for an update, they can do US, Euro, and Japanese if they wish. Euro VS US is different. So when you are saying that I am offering something without a log, or charts, that doesn't apply to me. Last I remember some tuners on here do not even have dyno charts.

Japanese software feels much more aggressive, and gives the car a much more light feel, I do not ask any of my customers to leave reviews. I do not even post this as a service I offer, customer was happy, he posted himself.

I have yet to flash a customers car with 240E Japanese and they are not shocked, most say it feels like a tune.

Longwong, if you are local to Los Angeles, come down, I will flash your car then put it back to US spec. You can be the judge.

So just curious if the AFR and timing maps are the same across the US 240E what makes the Jpsec software feel more aggressive? Is it just better throttle mapping? I'm more concerned if the car "feels" faster or the Jspec 240E software actually is physically more aggressive and is actually making more power.

[09m3power]

hey S65B40, how do you like the Jspec 240e? Do you feel the difference? Have you had any issues with smog?

[yoelev]

does anyone know when the 240e spec would have been standard in m3s? like by 2012 model year? sorry if already answered

[M-powerMode]

good stuff
