Yeah, looks smoother. I'll keep you guys posted with anything I find out.

Also I'd take it to another shop in your area that might have comparable knowledge as they might be able to tighten it up

At this point and time I would not recommend anyone get this tune. I gave them a chance to fix it from my first dyno and now the second one shows no difference. It should be much tighter. I'm waiting for more details and will let you guys know. I'm putting down the same power as a non tuned M5/M6 with the same mods I have which are listed in my signature.

Did you ever do a basline dyno before the tunes?

I'm not sure about that but I'm waiting to hear back from AMS's dyno tech with some more detailed info and that should be some time tomorrow. I'm not sure any shop would touch someone else's work.

That is one thing I did not do unfortunately. I saw a bunch of baseline dyno's but I didn't get a chance to do one myself. From the baseline dyno's I saw they were all pretty close as far as what they were putting down.

Ok, spoke with Jerry and we broke the before and after tunes down and viewed segments throughout the power band and there was a definitely 20-30hp/tq gain throughout the rpm range. As far as the choppyness goes that is just the smoothing they choose to view it in and jerry did show me by changing the smoothing how it can look more choppy or less so that isn't a concern. So after taking the time out with jerry and going over the tune at specific points throughout the rpm range there is a definite improvement and it was fairly easy for me to go in the 11.6's at the track with less than optimal conditions. So even though the stage 1 dyno vs the stage 2 dyno might not show a max hp/tq gain difference if you have the dynojet software to break the graph down and look at the rpm band between the 2 runs you see a significant difference in power throughout the rpms which you won't know if you just look at the max power figures.

Different days different conditions different dyno settings etc. can be responsible. I honestly am not convinced that stage 1 did much of anything, but we can't be sure bc of no baseline dyno. The big telling factor is trap speed , and at 125 mph that is better than any stock M6 we've seen but you do have Gruppe M and downpipes. It would be great if you could do some 60-130 times as I have done for my stock CP M6 . I'll try to get to the drags trip soon or at least do a pbox 1/4 mile to get a good comparison. Hard to say if your gains are from the tune or just your bolt on's

I agree with this and there are a few factors that were different on both days. Here they are:

Stage 1 Dyno 8/23/2013

Run Conditions: 95.03 F, 29.16 in-Hg, Humidity 7%, SAE: 1.03

I also had triple piece wheels on which weighed 35lbs per corner


Stage 2 Dyno 10/28/2013

Run Conditions: 65.49 F, 29.17 in-Hg, Humidity: 21%, SAE: 1.00

I had my HRE 21's on which weigh only 22lbs per corner.



Given this info... this could be the only difference between the 2 runs that made the gains.

How does this compare with hp increase @niko1414 saw from Switzer?

So Fellows, once again, yes or no Eurocharged Stage 1 tune for me?
Thanks!!

I vote no .

I vote no as well. I'm putting down the same max power as a similarly modded M5 with full exhaust, DP's and intakes. Now I don't know the difference in power at the mid range but I certainly think I should be putting down more max power than a non tuned car with similar mods.

Where did he post his information so I can take a look?

There you go.

As far as horsepower increase it looks similar with the Switzer tune showing slightly better whp results. My thing is that iND's M5 on the same AMS dyno pulled in 580whp as did mine with theirs having slightly less torque compared to mine. Same mods but I have a "tune" and they do not. This doesn't make sense to me. Maybe the tune give me more power throughout the mid range but I would have to do a more detailed comparison to find out.

I think that fact just proves the tune does very little over your mods . I would advocate everyone wait until a full tune comes out , esp if you have a 2014 or a CP . Since all current tunes are based off very old development files that tuners can only make a few tweaks to . Sure the Piggyback tunes like Switzer and Manhart do make power but I disagree with that approach( tricking the ECU into running more boost) on principle .

Agree 100%. I hear the AMS tune will be out soon

Manhart is NOT a piggyback.

It's the software remap with a additional boost controller (and boost only). The additional boost controller is installed ONLY on the Stage IV (700-750Hp version). Stage I to III is software remap and additional intake and exhaust mods.

There basic remap is the same dev software though , and stage 4 uses hardware to manipulate higher boost . My point is no one has a complete tune with full ECU control at this point .

Yes agreed, that's why I said it's got "the sofware remap". Meaning they also use the same "press file" as everyone else. But it's not a piggyback tune like the Hartge, AC Schnitzer etc.

BTW, seems like G-Power also uses the same methods as Manhart on their high end tune for the M5. In fact I suspect it's the MHR tune with MHR boost controller they also use...

And also agreed that so far no one has managed to get in full control of the ECU.

Thanks, I will be asking Eurocharged to refund my money.
I will wait until we have a real tune.

[pablocr]

How can we know when someone has a real ECU tune?
And how much longer for this to happen?
