why? I guess if you didn't want the dealer to see it go that high, but that's a two way street- in case you aren't sure if they flashed over it- take it to redline and see, as if you couldnt tell from the different feel anyway, haha

Really looking forward to reports on this! ESS has great rep in Euro.

Could you post the dimensions & weight of the DME so I can calculate shipping rates for it? Thanks!

All stages will adapt to current bolt-on mods including intakes, diverter valves, downpipes, and exhausts. The better the car can breathe, the more efficiently it will make more power!

I'm wondering about if 550nm torque will be the limit of the transmission (MT)? Assuming that adding hardware mods (downpipes, exhaust) will result in additional power and torque, will this exceed the long term reliability limits of the transmission, differential, clutch etc?

Do you offer a version of your stage 3 software with slightly reduced max torque as well?

Why do you choose to raise the max revs to 7200? I'm assuming that the max power will be reached much earlier (6000) so there is no need for a raised rev limiter.

Can I use this software option with a car equipped with OEM downpipes or aftermarket race catted downpipes as well or will there occur any problems?

Will the car, equipped with OEM downpipes and your stage 3 software with disabled post-cat O2 SES function, pass the smog tests in Germany (Euro4)?

It is about 3lbs and about 8x8x3.

wont the techs notice all that extra power during a test drive?

Regarding the drivetrain limitations, we have not seen any issues even with the R&D cars (which have been pushed harder than anything in the US). Your driving style will actually dictate the lifespan of your clutch, etc more than anything. If you abuse them, they wont last as long.

The stages are based on psi. If you want a lower torque production, perhaps order Stage 2 instead?

The redline increase is added if you want to use it. Just an added feature. That 200 rpm may come in handy if you need to hold a gear just a little longer. It is still making power up there, just beyond peak.

Yes, as long as the cats you use perform equally regarding emissions, you will have no problems.

OBD in the US is different than TUV. It will pass all TUV tests, even with the catless operation. In the US however, they test for and check readiness, which TUV does not.

I'm looking for the max power output of stage 3 (400hp) but with the slightly reduced max torque of stage 2 (540nm). Do you offer this option?

ESS can do anything you'd like, how about a custom tune with a lower peak boost down low like Stage 2, but the higher top end of Stage 3?

Perhaps call it Stage 2.5? We may have to name it after you!

PM me for details.

I guess this group buy is only for US customers right? Can this be arranged for EU customers shipping the DME to Norway?

This is for all E90post members, regardless of location!

What software version it will display if dealer plug in diagnosis computer to a E9x with ESS tuning? Will that void your factory warranty right there?

[Fugly M3]

good question

I do apologize if I didn't explain this better in previous posts. Let me clarify:

With each progressive Progman, BMW mostly makes emissions-related changes that mostly have little to no effect on performance. The US is very strict about things like this. However, occasionally, they do update a throttle curve, a wastegate control, a fuel pump threshold, a "tune detection" function, etc. If a new Progman contains a change that shows a marked improvement in the ESS mules, these changes are blended into the current flash. Even before that though, ESS figured out most of the changes BMW has made since 23.2 long before BMW got around to incorporating them in the US; things like lurching in the auto, turbo lag, and touchy throttle ramps.

What ESS then does is when you get your ESS flash, you have all of the tune plus the lastest Progman goodies applied to your DME without ever changing the software number (Progman). So, to the dealer, you still have the same Progman as your service history shows, but with all the latest improvements of the newest version already included.

Did I make understanding it better or worse?

[JacobT]

Thanks for the reply. So does ESS keep track of all customer's stock software version # so when he/she wants to re-flash back to stock, ESS can check the record and put the original software back?

According to your reply, instead of wiping out the whole DME memory, ESS just re-flash certain area and keeps the original software version intact?

makes it a little confusing for me-

My car is 29.2 i believe and came with no assist- so I retrofitted everyhting and it works, except I didnt sign up for and pay for assist, so I effectively just have phone- from what I heard, the 30 or 31 version eliminates the steering wheel control responses from the 29.2 if you don't have the phone- so for example- when I got my car and pushed the phone buttons/ voice dialing it would respond but there was no phone so it did nothing. I heard the latest update eliminates that doing nothing- ie the buttons just don't respond period- So I am worried that it will somehow cut off my phone connection- because my BT TCU is not programmed to my car- it's programmed and activated to another car adn I got it used on ebay and it just fools the car and works, So I don't want this to be cutoff- I don't think the ESS would do that, but just wondering...

Your actual stock file is archived forever for future use if needed. You can go back anytime.

And to answer yours and the next post at the same time:

This is not a master file that is flashed into each car like Alpina, Dinan, EvoTech, etc. Each car is individually programmed. So, your actual personal DME file is programmed... and only PERFORMANCE upgrades from higher Progmans (and even then, they have to be measurable by ESS) are blended in. All the while, retaining your original software version. The ESS Flash will not change how other non-engine systems like iDrive, Bluetooth, SOS, Sirius, etc operate.

[Fugly M3]

cool, now I just have a decision to make and a tax refund to receive, deciding between Let motorsports and this

Sounds excellent to me!

Sound really good. Thanks for the explanations. I will definitely put ESS upgrade on my wish list

so I have been reading the posts about BMW being able to detect even the Flashes, but you said this is different than the Dinan and others, meaning it cannot be detected if they look?

Actually, technically, the Dinan (Alpina) flash is not detectable by the dealer tools either. Dinan made a deal with BMW to report to them every time Dinan places their product on a car, then this information is logged in the vehicle's dealer service history. So the dealer is notified when the open your history and they know to go after Dinan for anything warranty related to the Dinan products. Therefore, your dealer knows it has Dinan before it even enters the shop. BMW would not give Dinan access to the history system, but they did let them send VINs and products installed in order to clarify who owes the warranty money. That is why they let them work with BMW dealers.
