Long story made short. For quite some time I was given the short end of the stick by a well known tuner company that is based out of Texas.



Previously I had a tune by HDtuning when I was naturally aspirated. I’m not going to lie to you but the car “felt fast”. However, I noticed that once in a while I would get phantom misfires and they would not stop until I turned off the car and turn the car back on.


I had the car checked out by a Mercedes specialist and they informed me that the tune was causing my issue.



Because I was already deciding to build the car I wasn’t worried too much about it since I was going to be supercharging the car and switching tuners anyways. For those interested in the build thread. C63 Facelift P30/31 Stage 2 Supercharged Build Thread



So I pulled the trigger on a Weistec stage 2 supercharger kit and a tune from Eurocharged.


I’m an easygoing guy. I am the type that is

not a complainer, exaggerator, or faker. But when I feel I am being taken for a ride I will make it known so as to prevent others from going through the same issue...



Moving on to my issue with the second tuning company... Every time I had an issue with my tune I would contact EC and would be immediately brushed off or told that I had to send them an email. I’m fact, The only way I could actually get in touch with the tuner was by email. This was frustrating for me because I was unable to emphasize the issues that I was dealing with.



My car on the EC tune ran ok but that’s all I knew at the time... so that’s what I stuck with. I’m a numbers type of person and was asking my original tuner about data logging and what software / hardware they recommend. They didn’t seem interested and were always slow to respond.


It got to the point where I wanted to just sell the car. My tuner at this point stopped responding to my emails when I asked them why their V7 supercharger tune kept misfiring. Their response was that the tune they provided me was for pump 93, (which is not even available in California)and it was too aggressive for 91.


I was told to go with the previous tune file they had sent me. What didn’t surprise me was that I still experienced the same symptoms with this tune. I was not provided with any alternative options.


Initially The car did feel fast. But that quickly turned out to be an illusion. I didn’t see any misfires on the cluster. I did notice that the car would jolt very violently even when I wasn’t attempting to join the car. When the car would joly it would cause my traction control to kick on. I took the car to the dyno and it made 550whp on pump 91 and 570whp on e40. The problems started after I started to daily my c63 and I was able to notice every shortfall and f the tune. The tune caused my car to run inconsistent.


I am located in California. Because I am not in Texas I had to reserve a time that would work for both my previous tuner and my dyno shop. I paid for what I thought would be a “dyno” tune. What I got was quite the opposite... to be honest I was better off putting the car completely back to stock.

For two months I went back and fourth with this tuner. I had nothing but issues with the car on their tune:

• misfiring
  
• Running too lean
  
• Multiple replacement of 02 sensors
  
• Multiple replacement of spark plugs
  
• Inconsistent power output
  
  
  
• Constantly dealing with a P061B code
  
• Replacement of MAF sensors.
• Replacement of Kooks GESI hi flow cats.

You get it.... The list went on.



I decided to give Eightysixtuned a shot. A forum member on here recommended me to Barry after explaining to him my frustration with my c63 build.



What I liked about Barry was that he took the time to actually listen to my frustrations. He didn’t promise me anything other than... “the car is going to drive as it is meant to”.



When speaking to him it is clear that he knows the m156 inside and out. He didn’t like to blame the other tuners for failing to properly tune my car. It’s understandable because I decided to do a build that involved using modified parts to make more power.



What he did do was work with me and has spent at-least 100+ hours on remapping my car from scratch. Barry had me purchase the HPtuners scan tool so he could diagnose any potential issues prior to tuning my car. In fact, he wouldn’t work on my car until he could make sure that there were no mechanical issues.



I sent him a log of the Eurocharged supercharged tune that I had.



Barry was able to see exactly what parameters were messed with and explained to my why my car was not running consistent.



When I asked Barry why nobody could seem to tune my car he informed me that from what he could see on my log files, my previous tuner relied on the Bosch motronics system to tune my car.



Basically, what this means is that the tune would force minimum and maximum timing, but the computer was left to decide whether or not the specific parameters were met to give more power over the stock tune.



He further explained that most big name tuners don’t actually take the time to properly tune our cars. Unfortunately they only mess with the AFR, injector pulse rate and raise the minimum and maximum timing. The rest is decided by the ECU. This is why my car was having issues with inconsistent power output.



it was clear to me that he really knew his ****.



Now that I am on Eightysixtuned I am no longer having any issues caused by the tune. I am honestly completely blown away by the service provided. My car pulls consistently like a freight train. If I ever have any issues with my car I will ask Barry and he can quickly diagnose the issue with the logs I send him. He was able to see that my 02 sensors were going out. I know Barry doesn’t like to advertise numbers but I feel like I should post this up anyways. My car made 600WHP on pump gas. No e85.

Barry is a class act!

thebug44

This is absolutely legendary. I can’t wait to move to HPTuners with Barry

roadtalontsi

glad to hear. It's sad how differently some "tuned" car drive and how people just live with them. It'd be understandable if you had some crazy giant race cams and a 4000rpm stall converter, lol but they are literally usually a headers and tune car hahaha. Just add 10 degrees of maximum timing and let the ecu pull 15 of it out. that'll do.

eschow

I don't have good feelings about my remote dyno tune I got with EC in Texas.
1) Was strapped down on the dyno, waiting for the tuner to meet us online. Tuner was about 1.5 hours late
2) Communication was only done via email WHILE ON DYNO
3) Only wanted to see the dyno graph with mph overlaid on x axis instead of RPM, which means there was no tuning via logs (?)
4) Race map to be able to run MS109 did **** all (complete waste of a $130 barrel). No 1/4mile or mph difference

I'll most likely to switching to Eightysixtuned in the summer time.

PeterA90

Dyno numbers really don’t mean much. Eurocharged focuses on PEAK... to trick you into thinking their tune is superior to others. But good tunes don’t just focus on peak... they focus power under and throughout the curve.

Your results don’t surprise me. Think about It? how does Jerry custom tune a car without data?

** disclaimer If your having issues just unplug battery lol... that’s EC in a nutshell.

SikC63

I guess I’m the idiot who fell for it. I was following the hype to go with Eurocharged company but it was a complete disappointment. Not to mention I almost blew my engine on their tune! Dude my Fueling was out of wack. On some days my car ran super lean and others it ran rich. Wtf?! And here I was willing to work with them so that they can get my car dialed in. But you sir, you are right. How the hell can Eurocharged dyno tune my car if all they are going off of is my dyno graph and AFR? Is this a joke?!



Eightysixtuned literally sent me an email and specifically asked me to record over 135 parameters with HPtuners.

Based off of all the data I provided... I was not surprised that Barry was able to get my car to fire right up without any hesitation on the first tune.

Here’s a video of my dyno. Car peaked at 609 WHP on a mustang dyno.

I am also that idiot. I purchased a can tune from them for my e85 kit and my car is running so rich and was spitting so many flames. Looks like he accidentally sent me a flame tune when I never requested it. I will be moving to HPTuners and tune from Barry very soon once I get my car back to where it should be.

hachiroku

one thing the amount of sensor data allows me to view, I can also see if wheel spin occured by mapping the difference in wheel speed at the front and rear tires and if traction control was triggered.

based off this type of data I can then limit throttle or limit power to aid in wheel spin issues while drag racing if the customer is interested in doing so.

thebug44

how do you manage tuning multiple cars at the same time? I imagine it might be confusing sometimes and super busy since you are basically doing a custom tune for everyone

hachiroku

there hasn't been to large of a customer base at this point in time as most customers simply care about what numbers my tunes have put down on the dyno...i don't sell numbers so i don't bother with most who contact me.

when i do have a lot on my plate, i do push off some customers a day or two before taking on new work to avoid overwhelming myself. i am doing this for the love, not to treat it like a cafeteria where you line up and get what i give you even if you don't want it.

also, sadly...many who have already paid for a tune somewhere else, inquire but don't have it in them to spend anymore on a tune even though they are dealing with many drivability issues. in that i've learned that the vast majority of M156 owners use their vehicles as weekend cars and not daily drivers.

KXC

Barry is very organized. The instructions for the tuning process he sends are very detailed. I imagine he has a good system for keeping tunes grouped with the VIN or customer.

sirius9

That torque figure is VERY impressive and very EARLY as well. Very similar to biturbos set up.

Just a query, would that amount of torque not hurt the transmission in the long run?
Plus drivability around town, would it not be jerky as any pedal power and the torque comes in massively?

Impressive work by Barry!

hachiroku

to answer your question. I asked the mbc23k if he wanted me to limit the onset of torque. he said no. I asked, do you want all the available power, he said yes. we haven't seen any transmission issues so far. and are not going to say their won't be, just haven't experienced any issues as of yet. currently the factory 722.9 MCT shifts faster and more direct than original, so haven't had any reason to worry at the moment. in the future we may have something different to report but the owner of the vehicle is ok with that.

drivability around town is exactly like OEM. I personally took his car for a spin a few weeks ago when I was in Los Angeles and was blown away...simply blown away with how OEM+ the car felt while still being the fastest thing I've ever driven. his car is so razor sharp in steering, handing, and ride quality, the added combination of power when you get on it is a treat. literally, if an elderly person drove the car they would never know it made so much power. the power does not come on until you want it to and is as smooth as ever. it is really something that is amazing to drive personally.
