I have to start by saying that I'm just an ordinary person with a typical office job so I'm not an expert with car tuning or analyzing algorithms.
Hence dyno charts to me are just papers with numbers and if I don't even scrutinize my monthly phone bills or bank statements, dyno charts bear little meanings to me.
What matters more to me is really how the car moves and reacts to your right foot.
That instincts you get when you are behind the wheel instead of obsessing over a paper with 4 curves on axes.
Of course having said that, the feeling of how you like your car is very subjective.
Some prefer comfort over power and some will go all out for power forgoing comfort.
Add in aesthetics and ICE dimensions, the ideal car ride becomes a very different ball game for everyone.
My perspective might not be agreeable with everyone but I'm just sharing the professionalism and great outcome that I have experienced.
And I'm also hoping to share some insights for those who are considering to tune your ride.
WHY CUSTOM TUNE:
Having tuned a couple or more times with some tuners on my previous ride, I guess I can differentiate between good and bad tuning experiences.
Naturally I have a rough idea what I would like for my ride.
Piggyback is never an ideal option for me because I don't fancy the idea of having software to deceive your hardware to work into overdrive.
Imagine it's like telling your mobile phone to go into fast charging mode without addressing heat dissipation in the hardware. (Kind of like a recipe for another epic phone explosion)
Hence ideally I would like to address intake, exhaust and maybe turbo when I tune my ECU which can only be achieved via a custom tune (to my own driving style).
Tuning a Merc is not rocket science but flashing its ECU is probably not easy.
Naturally since they are selling a C200 and C250 with same specifications only different mapping.
Having someone flash a C200 map that beats a C250 will make their Merc product positioning look stupid.
The main hurdle will be to find someone who can both tune AND flash the ECU.
I tried asking around for workshops who can do that but even though a couple of workshops claimed they could flash the ECU, they did not give me great confidence that they are able to let me custom tune during our conversations.
In fact I have already given up hope that we can find a tuner who can both flash and tune a Merc ECU until I chanced upon Dynotechnica through the Sgmerc chat groups.
Being a skeptic as I am and after all the futile search, I wasn't convinced that this workshop can do that either.
Luckily someone (I shall refer to him as K from now) from the group chat have the same ride as me and K said he was going to get his ride done up by Dynotechnica.
In the chat, K seems pretty confident that Dynotechnica cos he has been fixing up his rides with them for the past 10+ years.
As at that time they were still waiting for the hardware to arrive so I did some of own research online before going down to Dynotechnica to understand more.
Not going to elaborate on the hardware but in a nutshell, it unlocks "anti-tuning" feature and allows a great extent of custom tune.
More info here on Trasdata by Dimsport
The hardware finally arrived and K went down to Dynotechnica earlier to get his ECU removed.
I reached later in time to see how the technicians opened up the ECU.
They seemed to have a good sense as to where the silicon glue lines are when slicing the penknife across the ECU part lines.
On that note I was pretty impressed with their craftsmanship.
Then K introduced me to Benny, the main tuner.
Benny was very detailed and comprehensive in his explanation on what he will be doing for K's ride step by step from scanning the ECU to uploading to Dimsport for verifications, and to using dyno for tuning.
Obviously K has already told Benny about his plans for turbo and exhaust as well and Benny was able to plan it for K.
As I mentioned earlier on my tuning experiences, Benny came across to me as a very good if not best tuner I have met.
Some may argue that I haven't even tuned my ride but after half a day in the workshop with Benny, I have absolute confidence that he is the right guy to help me with my ride.
I wanted to be very sure that Dynotechnica is able to deliver hence waited to see if K has any issues with his ride first.
One week after K tuned his ride, everything was still working perfectly and he experienced no CEL issues nor power loss.
That firmed up my decision and I fixed a date with Benny to start the operation for my ride.
PROFESSIONALISM AND PERSONALIZED:
Ask any customer what are the most important traits they would like to see in the service industry and they will probably say professionalism but with a personalized touch as one of their top few answers.
These are the exact words I have to describe Benny and his team.
As I am working regular hours (unlike some of my Sgmerc forum friends), Ubi is pretty far for me to get to.
So I arranged with Benny for me to drop off my ride the night before and as he stays in the west, he was also kind enough to send me back to my door step.
During the ride, I explained to Benny what my intentions are for my ride (I will skip the details here as different people have different requirements).
Benny was able to give me some options for me to decide and he explained to me some of the pros and cons for each option.
This is where I will advice whoever am thinking of tuning your ride, do have a conversation with Benny prior so that he can better serve your needs/wants (nobody needs more power... It's more of a want)
The next day arrives, Benny actually sent me updates in the morning and afternoon on what is actually happening to my ride.
I wasn't really expecting that but was just hoping that everything will be done by the evening so that I can pick it up and go home after work.
Unfortunately at about 3pm, Benny texted me saying that I might need to leave my ride with him for one more day as he has to wait for Dimsport to get back to him about my map.
He explained that he needs to spend some time to tune the ride even after getting the map back from Dimsport.
Bummer but what's another day of Uber anyway.
On day two, again Benny sent me updates and a picture of the dyno chart after the tuning.
I finally got to the workshop in the evening (FYI, Comfort costs less than Uber during peak hours).
When I reached, Benny brought me out for a test drive.
For the record, I was driving a 2.5l turbo coupe with cleared airway before this ride.
After changing to the current ride, I had missed the G force that pulls you backwards whenever you floor the accelerator.
I have finally found back the thrill...
Obviously not as powerful as the previous ride but this was good enough for me.
Benny had also helped me tune my ride to be smoother and more comfortable in the lower RPMs and only to kick in on a slightly later stage.
That's cos I wasn't too keen to make the car all jerky and stuff considering some days I have to ferry my wife and hopefully kids in the future.
I wanted it to be comfort still but when I am alone in my car, I have to option to go on quick acceleration.
He advised me to drive around for a week and if I need to further customize my driving style, he will make the tweaks for me.
Some of my forum friends have the opportunity to sit in my ride and I have only heard good feedback from everyone.
No loud exhaust let alone droning, nice turbo sound, fantastic torque (and of cos the KW springs were really comfortable).
In conclusion, I feel that this is how a Mercedes (or a even a good car) should behave.
Tame when you need to have comfort (and avoid complaints from your wife/mum about loud noise and reckless driving), and when you need it, the surging power that kicks in smoothly for all your desires.
Thanks for reading this long posting.
I wanted to make sure I write an objective review about Benny and Dynotechnica so I actually waited for a week or two to make sure my ride was fine before penning down my thoughts.
In fact, just a couple of days back, Benny actually messaged me to ask me how is my ride.
To be honest, I have never met any workshops that does follow-ups on their work.
Really impressed with the tuning outcome and their service level.
Thumbs up for them!
