Is it Worth Dyno-Tuning after a "Box Tune"?
Hey Guys,
I currently have a Eurocharged supercharger pulley, upgraded IC pump, and a Eurocharged "email tune". I've been considering getting a dyno tune, but I'm debating with myself whether or not it's worth the $$. Oh, also, I have a CLS55 but I'm posting in here because I generally get better responses in here..please don't shoot me!
So I have a local place that can dyno tune for approx $800 (includes baseline dyno, the tune and all dyno time). They do have experience tuning euro's (MB's, BMW)
Do you think it would be worth it?

If you have a car dyno tuned by another tuner, they will typically just wipe your EC map and use there own baseline tune. I would do as above get Jerry to remote in and tune your existing file. That way you only have the dyno cost and pay EC for the custom tuning.

I wouldnt have custom dyno tune done unless it was by a well known tuner. Having someone else do it may cause a hiccup here and there or worse... not excactly a cheap platform to take chanced with for a few extra hp

It has already been said many times but the simple answer is YES. Do not have some shop do it though, just go to the dyno, do a couple runs and then send the graphs to Jerry (with the air/fuel on the graph) and he will tweak the file. He will then send you back a new file to load if you have the cable and flash loader software or he can get on the shops wifi and remote in and load it himself. It only takes 1 revision to make a significant difference.
I went up like 32whp from the box tune to the dyno tune Jerry did.
If you are a newer customer to EC then it may cost you like $35 or something like that for a tune adjustment and cost you whatever the shop charges for a few pulls or get a 1 hour rental of the dyno. But it will only take Jerry one revision after you send him a graph or two and you will be set.

This place is a joke.
At Rage-Teks dyno day last year, Jerry remote tuned me and I picked up 28whp over the box tune, and improved driveability. It took 2 reflashes to get it right. If you have the opportunity, I would dyno tune...or even better now, use EC's data logging for an even more accurate street tune.

This is my next "project". I posted up that DIY on the new EuroFlash v2.0 software yesterday, but what I really want to do is learn how to do the datalogging that's built-in to that software so that I can send it to Jerry for analysis and refinement.
Does anyone know what sort of datalogging is most useful to them? Is it just a couple pulls at WOT so that he can see AFRs, timing and IATs or are there a few other "part throttle" activities that should be collected as well?
I'm starting to feel brave again, now that my USB driver issue has been resolved and the software is more stable... so maybe this weekend I'll "cable up" and go for a drive!

From what I have been told, these cars are relatively difficult to tune, especially with regards to part throttle maps. I would datalog both part and WOT, and would take multiple logs of each to weed out any irregularities. Try to be as scientific as possible with real world logging, i.e., start your pulls at the same IAT and ambient temps for instance. If possible, try to do 1st through 3rd gear pulls.
The more PIDs you can log real-time the better, more than 4 or so PIDs being logged from the OBD port can cause the datarate to drop making the results less accurate.
Attached is a pic of the PID's I normally log, I also log TPS real time, but inadvertently removed it from this file.
Hope this helps.
*edit* My car was tuned on a dyno, but if possible real world logging/tuning may provide better results. The file on my car hasn't been touched in over a year, still running safe and strong.

Nice first post!!! I bet Jerry will like this too! Jerry has a company called Eurocharged Performance. He tunes MB cars.
I'm doing a remote dyno tune with Jerry tomorrow to better the EC box tune recently installed. Looking forward to it.

Thanks haha. I've been on here for about 6 months or so, just haven't found the need to post until now. So I just call the company Eurocharged in Texas and ask for him? I just want to make sure I am calling the right place. haha

$800 seems a bit aggressive to me. You should be able to find a dyno to rent by the hour and get a custom tune for $250-$400.
I am BIG on cooling right now as I have seen night and day differences in "cooling" coming from dyno pulls (air/fuel ratio, car pulling and HP increasing in higher RPM, etc). Let me be very clear; it is just not me who is big on cooling! The "veterans" and "experts" (we all see the posts) all preach, cool, cool, cool...
First Things First; get yourself a Killer Chiller (trunk tank, whatever) so the "custom tune" can maximized. If the car is getting hot and pulling timing on a "box tune" sure as sh8t it will do the same thing with a custom tune...
I don't want to open a can of worms on this as there are 20 threads with "what mods to do first?". I would argue cooling should be the first thing anyone does.
This is my 2nd E55 (my first was bone stock and ran 12.16 @ 115) and if I could do it over I would do a Killer Chiller (not a fan of trunk tanks; my car is not a "drag car"), mild s/c pulley, headers, and custom tune and call it quits.
Again, welcome "over here" an stop by again, soon!
