Akra EVO + ESS ECU Tune Dyno

[tha_good_life]

Today was the first time I dyno'd my 2010 E92 M3 (manual) and I was a little disappointed with the results compared to some of the numbers I've seen on the forum. I was expecting to hit somewhere around 370-380hp with the mods I have. Out of three runs, I ended up with the best run at 352 hp and 250 tq. Is this unusual for this type of mod? There was a stock 2012 e90 pushing close to 350 something to the wheel.

I guess my car is not healthy like everyone else I'm not sure if the 1000 miles left before the next oil change has to do anything with the lost hp?

Don't mind the big dip on the 3rd run, I eased off the gas because I thought I stepped on throttle too soon. One thing I noticed is the small decrease in HP around 2200 RPM. I believe I heard people complaining about this dip?

Mods: Akrapovic Evolution + ESS ECU tune

Dyno system: Dynojet

Results: 351HP & 249TQ

I was going to blame it in the dyno or the day (suboptimal conditions), but if a stock M3 under similar conditions did as much power as you with mods... Well, it appears to be kind of weak, sorry. Then I thought about your car having an old software, but the ESS tune (if installed recently), must have updated your software to 231E. When did you get the ESS tune? If you got it a while ago, maybe you can ask for a newer version.

I believe the software tune you are speaking of is only for DCT? I can be wrong. I recently had the ECU mode done not that long ago.

231E is the most recent DME software version from BMW. Apparently, as discussed in another recent thread, updating to this new software version, improves performance. I believe the 231E software applies to both MT and DCT, but I might be wrong. Will look at the thread again.

Roman@ESS states in this same thread, that when you buy the ESS tune, you are automatically updated to a tuned version of software 231E.

Roman@ESS: "We have been tuning with 231E since its release. When a customer orders our performance software they are updated to a tuned version of 231E automatically so there is no need to get this update before purchasing our tune."

So if you had the ECU mod (ESS tune) done recently, your tune probably includes the 231E software update. You can PM Roman and ask him if your tune includes the 231E update or not. Its worth a shot.

The DCT software can also be updated. I believe this is a software separate from the 231E.

Thanks for the info. I'm reading up on the 231E software update!

I did a dynapack Dyno and got much higher results when i dyno'ed in 3rd gear instead of 5th gear. But I dont know if that is the same for a dynojet dyno

Dynos in our cars should be done in 4th gear...

Never did a dynojet and Im no expert. Im just stating my results were much higher in 3rd for dynapack. PencilGeek told me 3rd gear for dynapack dyno and was happy with results. but dynojet is probably different.

edit- tried 4th gear to

These runs were done on 4th gear, M mode, and traction control off.

Nice gains!

anyone else can chime in?

air fuel is leaning way out up top if that sensor is right - have ESS send you another file.

but work on this:

I'm talking to Roman at the moment. I think the dyno had a malfunction on their a/f ratio. They kept changing it in and out on other cars, but I don't believe that is the factor for the results. I have been reading on the links you posted but ESS claims all their tunes are ran on the updated software.

How large were your files? 231E update is a separate file @ ~5MB that needs to be loaded before the tune. The actual tune is ~2MB.

Otherwise, you may still be >231E.

ESS only sent me one file.

It's best you contact ESS directly to get this worked out.

Thanks Tom! I'm assuming there is no way for me to find out with the direct flash tool I have what software i'm running?

When you performed your original read, what was the file name given?

Please PM me if necessary.

I guess your numbers are a little low, and i see why you're disappointed.

I think people expect too much when doing basic bolt ons to our motors.
