Akra EVO + ESS ECU Tune Dyno

[Alekshop]

Did you flash the tune while the car was on the dyno ? Sometimes these cars need some adaptation time ...

Yes I did. I realized that. I started the car the next morning and my RPM was bouncing all over the place because of the cold start delete. I contacted ESS and they said the tune needs time to adapt to the car.

Aleks, how long should I have waited to get it re-dyno after downloading the tune?

These cars tend to adapt fairly quickly. It would probably be ideal to drive around for awhile (<50mi), but on the dyno, I think doing a lot of repetitive runs should suffice.

No one told me this. As you can see, the graph did get better on each run. but the HP didn't move much.

So I may have overlooked it. In your three latest dynos, is that tune'd file from ESS for the latest 231E version?

A 13whp and 12wtq is pretty nice.

Yeah man, I think you got pretty solid gains from your baseline. Ignoring all max values, you'll notice a nice increase in area under the curve. Personally, I think that's what is felt on the street or track.

I believe these motors and DMEs are incredibly sensitive to IATs and Fuel. So if your dyno shop didn't have ample cooling, that could also hinder or skew your dyno measurements.

Provided your car is healthy, I can almost guarantee that you would be neck and neck with a car with similar mods that could have potentially put down 380whp on other dynos. Dynos are tricky and rather tedious to work with.

The more important thing is that you had a baseline and you showed a nice gain from there.

I technically didn't have a real baseline since my baseline included a Akra EVO exhaust installed. I didn't dyno the car stock, which is a mistake on my end.

All good man. At least you can see where the tune brought you.

If your car is running strong and if it pairs well with other cars on the street performance wise, I wouldn't even fret about the numbers.

I've seen dynos of cars putting around around 345whp with the Akra Evo, 91OCT, and DCT, so you're not too far from that.

Thanks for the feedback!

So here is my quest to find the answer. I had my car dyno'd last week with the following modification: Akra Evo + ESS Tune. I was very disappointed with the results peaking at 351WHP and 249 WTQ. After doing some research, I found out that I was running on an old BMW software E89X-10-12-503. I took my car in for the 30k oil change and had my car reflashed to the current OS E89X-12-03-502. My initial impression after I picked up the car, there is some lost HP for sure without the ESS tune. Some of the stuff on iDrive did change. AND my LCI has to get re-coded.
So today, I tested the theory if the updated OS will give some extra WHP on top of the ESS tune. RuneFile 5 was with the updated OS + Akra Evo, which produced 339WHP and 251lbs TQ. A lost of 12WHP and a 2lbs TQ gain. Still, a little lower than I expected. RuneFile 8 was with the ESS tune with a gain of 1WHP and 7lb TQ gain! RuneFile 9 was running the car on 5th gear 352WHP and 263lbs TQ with being flat on WHP but a gain of 14lbs TQ!

Overall, not a substantial gain in WHP, but 14lbs TQ gain. At the end of the day, at least the ESS tune did produce results. It's really hard to tell if the new OS software gave my car extra HP or not since I didn't have baseline to work with. I hope this helps the people who wants to update their software.

With the Akra exhaust and ESS tune there is usually a dip in the lower RPM's of which I did not see in this test. I wonder if the new OEM software update got rid of this dip. ESS never updated on this dip being fixed with the tune and Akra exhaust.

No dip here.

Just read this thread, I also have 2010 m3 DCT, ESS tune, BMC air filter, Full amuse ericsson exhaust system 100cell race cat, straight pipe to muffler. my dyno are close to yours and I'm very disappointed with my dyno result too. And looks like updating to 231E didn't do much on the power gain for your car.

Maybe just a 2010 thing.

Here are my result without the updated 231E or 240E:

Ouch. My bone stock 11 E90 dyno'd at 336 whp. I have the old software for some reason.

Wow did I see this correctly, you have a full akro system and dynoed a 339 and then someone else also with catless system (100 cats) did in the 330's as well? I honestly would simply guess 2010 had a run of weak cars, or else you both babied the car too much during break in-but even that really should not explain this low of numbers.

Most bone stockers are hitting 350. Mine was a 351 like the average. With xpipe/HFC and AA and 95 octane was at 381.

I think unfortunately you should got a weak horse out of the factory. Just like some are stronger. All luck of the draw. Unliekly you will ever notice though but I know mentally it still sucks.

Try getting an AA filter, some race fuel to increase octane to atleast 95 by mixing with 91/93 and give it a whirl again. If you do no tbreak 355 there is clearly just something weak about the engine

There is a lot of possibilities I'm going to eventually SC it.

350whp stock, was that SAE or STD reading?
Do you have dyno result with 91 octane stock/moded?
What year is your m?

Otherwise, you may still be >231E.

I want to know what is the newest version of tune? Isn't 231E？ Can i update the tune from BMW? Or i have to buy one of the e-flash from vendors?
