We have seen none. Our tuner prefers the 231 base file if you ask him.

[Updated FAQ]

I am currently on software version 231E now. Are there any benefits to updating to 240E?
If 190E or earlier, we recommend updating to at least 231E, preferably 240E. At this time, the update path from 231E to 240E seem to be primarily focused on emissions, with no change in performance. However, there is no harm in updating to 240E if desired.

Hi, interesting thread!

Is there any difference in new and old ECUs when it comes to the tuning or read/write time? I heard newer hardware versions (2011- or so) take much longer to read than 2008 for example. And that it isn't possible to read out the whole ECU in the newer versions as well.

Do you tuners have to approach the 2011- cars any differently than the older ones?

Thanks
Chris

Another question .

Given my setup stays stock, what would the estimated outcome be with the tune and the same standard fuel? The dyno below was done with 95 ROZ fuel which is I believe 93 Octane over in the US. I would not want to put any different fuel in to achieve more power.

Here is my dyno, 2 runs:



Leistung is whp SAE and Drehmoment is wtq.

Software is 170E

This is def the way to go as far as Tunes go guys. ESS + EAS can't go wrong with that combo.

Ill be getting my new m3 set up with ESS and EAS in a few weeks!

Easy to use with very good support. I had my base file updated to the latest version when I did my tune. Im looking forward to loading ESS supercharger software with my cable if I can get it past the wife this spring.

Awesome, you will even be able to retain the same cable when going boosted.

bro where did you get your dyno done..im in Germany too...down in Bavaria..we should link up at the Ring

Note: E-Flash Software Suite v.10 released today.

For those that receive a "Device may be incorrectly coded" error when attempting to read your DME, you may be using v.9 or earlier software. If you have purchased your E-Flash interface from us, please contact us for an updated version of E-Flash Software Suite.

FAQ updated.

Just wanted to share a recent ESS E-Flash before/after dyno session on a 2009 M3 with some minor bolt-ons. The only thing missing was a performance flash tune.

ESS's E-Flash was immediately added and the M3 strapped to the dyno. The results were very impressive.



Vehicle
2009 BMW M3 DCT

Modifications
Macht Schnell Performance Filter
Fabspeed Resonated X-Pipe (primary catalysts intact)
Rogue UnderDrive Pulley
Remus Race axleback

Options
[X] Update to 240E (previously on 200E OS)
[X] Remove cold start cat heat cycle/camshaft phasing (for smoother cold starts)
[X] Retain OEM Rev limiter (customer specified)
[X] Remove top speed governor/VMAX

M3 was originally on 200E OS, which was updated to 240E before applying the ESS flash tune. Plugs were already changed approximately 500mi ago as part of scheduled maintenance.

As you can see, gains are achieved throughout the entire powerband. Those with 93 at the pump can expect even better results

Dyno added to post #3.

Just wanted to bump this thread and the awesome walkthrough video that EAS has for the eflash process.

I was working with AJ@ESS on a few things with my ESS kit software and I was a little fuzzy on what to do throughout the process and wanted to just double check and the video was very helpful in confirming everything.

Thanks again for making that video EAS!

Tempted to do this tune through EAS since I'm in the OC...

How is the reliability of this tune on the track? Engine doesnt run hotter than stock? Timing isn't so aggressive that the engine starts having to pull alot of timing? Any graphs that show this after the engine is well heat soaked?

We know of quite a few people that run ESS tunes on the track with nothing but praise. As long as race fuel is used on the track (instead of 91), you shouldn't run into any timing issues.

Glad you are up and running with the new update!

Good to know.

I am assuming with the software I can always re flash back to the oe softwre for track use on a hot day with socal 91 oct correct? However the cable is not stand alone and I would need a computer to switch? Would be pretty awesome to switch via iPhone or iPad or a handheld switcher.

Also, rather than running race fuel on the track as that can get very pricey... Has anyone ran water meth on the M3 to raise octane levels? And prevent timing retardation and engine knock? I still have my water meth kit from my 2010 GTI as well as a case of Snow Performance Boost Juice... Hmmm

The E-Flash cable is USB-based, you will need a laptop/netbook in order to load/backup tunes.

Simply bring race gas with you to the track or use the Torco Accelerator additive. We use the same additive on our S/C applications when race gas isn't readily available.

After a bit of testing, ESS has just released V2 of their E-Flash software for Akrapovic-equipped users with revised drivability/response.

Here's an independent review from member SROC5:

First off, ESS's timing couldn't have been better, they sent me the file in perfect timing to test at the track (in typical Roman / AJ excellent customer service fashion).

Results are straight forward, there is improved overall response from driver input (throttle modulation, etc.) and definitely improved partial throttle under load. The changes are not drastic nor power related, but it's certainly feels great at all rev ranges and a bit livelier due to the refined tuning.

Thanks ESS! and be sure to reach out to Roman for your updated Tune File if he hasn't reached out already.Here's the sweet sound of that Akra Evo + ESS Tune power!!!

All new flashes will be released as V2. Those equipped with earlier ESS flashes can be reflashed to V2 at no charge.

For more information, please contact EAS or ESS directly via phone or email.
