SCAMG13

First off id like to thank Jerry at eurocharged for the awesome after hours support. (Had an issue getting the factory tune back in the car which we are working out... Not a very big deal).
The tests were done on a dynapack at WORKS motorsports(Sonoma Raceway).
dyno room temps ranged from 80f-90f
pulls made in 5th gear

As i mentioned, there were some difficulties with the factory tune so i am a little confused by the results as they are very similar.(going to follow up with Jerry but ill post it anyways)
You can definitely see how much smoother the curve is on the eurocharged tune.



Stock tune- Notice the dip in the curve at 4k.




Stock tune- Torque and AFR




EC tune- 4K is smoother




EC tune- Torque and AFR




Stock tune- Room temp




EC tune- Room temp

Is your car a P31?

SCAMG13

Yes, it has the P31 package.

sighting

For reference, mine pretty much gave me the exact same readings, mine actually lost 2hp with the ECU Tune.

The tuned files were the RED and LIGHT Green Lines
The ones which produced the lowest numbers..

Ingenieur

Looks like no change?

Looks like the tune replicates the PP oem tune?

Autosport7

These are the most confusing dyno graphs I have ever seen. Not sure what I am looking at.... Not a pro either by any means.

Am I reading this right?
Base Line - 423.1hp
Tuned Control - 424.9hp

Base Line seems high and the Tuned Control seems low.
I am so confused by this.

sighting

Updated with larger images
I have a 2012 P31

The ECU Tuned Runs are in Red and Light Green
The Stock Tune Runs are in Magenta and Light and Dark Blue

In my case i think my top base was 431 and my top Tunes was 429 so I actually went -2 HP with the Tune

Autosport7

Okay this file actually make a little sense to me.
I think yellow is base line and green is tuned.
I think you went from 421.61whp to 431.76whp and 392.76trq to 398.055

And if you are a P31 package that is why I was thinking your original docs were a bit high on base line. Looks like on a P31 package the EX tune is worth 10whp and 6wtrq if I am looking at this correct....

sighting

Well no. that was just the lowest negative. The green does not show the green line it was just where you placed the cursor. So technically the highest NON Flashed was 10 HP MORE than the lowest NON one but it was the first one so the second run was more inline.

This was how i ran it.
First run was with ECU flashed
Second run was with it removed, they were almost identical/
Third and Forth run was ECU flashed
Fifth was ECU Stock.

So actually my best flashed was -2 i think. vs my best Stock
So in short they were pretty much identical

Wich is inline with the OP's numbers and conclusion,
I don't have the RAW file anymore, i can't find it but the only difference is that i think i found the correct gearing ratio for the gear which is 3.861 and not 3.88 so maybe that adds the +7hp i have over his.

The top Torque was the light blue line - Stock
The lowest Torque was the red line - Tuned

The top HP was the Light Blue line - Stock
And the lowest was the light green line - Tuned

Autosport7

Well that makes a little more sense to me now.
You seem to be handling the 2 hp less with tune better than I would be tho.

Ingenieur

So 2 PP and before/after essentially the same
Hmmmmm....
Sounds like they are using a tune similar to the oem PP
Which is fine with me,,,safe

Autosport7

But haven't we witnessed EC tuned non pp running higher dyno #'s than this...?

sighting

Well I am not, and until now that I found another member on here with raw numbers the Tuner needs to step to the plate on helping us out or refunding us.

I reached out to them again and awaiting their feedback.
There is another member on here also with the same setup so lets see how this Reputable Tuner handles this.

Ingenieur

If we assume the dyno's are accurate(relative to before/after) and since done same dyno same day for each car a safe assumption

The only other explanation is that the tune(s) did not get downloaded?

We have seen higher gains
Definitely on non PP
Can't recall on PP cars

Makes sense if all they do is remove the oem throttle restriction

sighting

Don't focus to much on the Numbers, focus on the delta between them. Some dynes rate much higher than others ect.. Different day, altitude .. you get the picture/

So you need to look at the gains between the base and tuned run and work of that.
I use to have a non P31 2010 and the ECU tune made a massive jump/

But it looks like there is 0 gain from a p31 tune

SCAMG13

Sorry for the delay.
I'd like to point out that the tune is not only for making higher numbers (which at this power level, and limitations on tire size is useless). I'm am very happy with how much better the car drives in a smooth manner. The power band is clearly refined in the tuned pulls. The factory tune was pulling power around 4k for some reason.
Also, give Jerry till next week to get back to you. I was lucky enough to catch him just before he jumped on a plane Tuesday. I've worked with him very little, but coming from a very similar career I can tell you he knows his stuff from the discussion we had.

As I mentioned in my original post, I had issues with my factory file which could explain what I'm seeing, but I wont know until I do a little tinkering with the memory on the programmer or wait for Jerry. Will keep you posted.

Was inquiring about the Eruocharged tune as well and am considering it. I too have the P31/Performance Pack C63. I am wondering if it is worth the cost. The rep I spoke to said I would be at about 520-540hp.

These charts aren't what I expected.
