TunedMercedes began by publishing calibration training content using HPTuners, focusing on the actual science and art of tuning rather than simply reading and writing files. At the time, this was a relatively underserved area of the industry. Most tuners and file services focused primarily on extracting and flashing files, while […]
For years, we’ve used our 3D printing to manufacture our own performance products, including air intake systems and engine bay components. After printing tens of thousands of dollars’ worth of parts, we’ve developed a process that delivers reliable, high-temperature components capable of surviving demanding automotive environments. We have tested these […]
With the Tractrix website is currently down we have provided a copy of drivers for the ubiquitous Open Port 2.0 to download here: https://web.archive.org/web/20250726174605/https://www.tactrix.com/downloads/openport2_setup_1024820.exe — credit aredditrabbit
⚙️ The Core Concept — Torque as Currency Inside the ECU, torque is the universal language. Every subsystem — engine, transmission, traction control, A/C, even cruise control — speaks in torque requests and torque permissions, not raw throttle or boost. You can think of torque like a digital currency the […]
Internal Combustion Isn’t Done We’re still finding real gains: smarter fueling closer to λ≈1, electrically actuated valves, and 3D-printed blocks with lattice cooling and closed-deck strength. TL;DR — Where the gains come from Thermals: Lattice coolant jackets raise area → lower ΔT and distortion under boost. Strength: Closed-deck rings + […]
How We Use AI to Double-Check Our Tunes AI doesn’t “write” your tune here. It audits it—catching conflicts and edge-case risks before a human calibrator signs off. Safe Calibrations Return-to-Stock in Minutes Datalog Review Included TL;DR — What this means for you Fewer surprises: cross-checks find mismatched limits (e.g., driver-wish […]
We talk about the importance of annealing 3D printed car parts multiple times, rather than just following the recommended process once, to ensure the part is properly heat-treated for automotive performance applications. What is up, everybody? I’ve seen a lot of people get into 3D printing, uh, car parts, and […]
KLAAD02: We talk about the KLAAD Family of Torque Error Allowance Modifiers Characteristic Map of Steady State Exhaust Manifold Temperature in Homogeneous Engine Operation Follow for more Maps of the Day.
All right. Yesterday, we were given a new printer, X-Max 3. We now have redundancy. This will help us get through our insane backlog of air intakes. So if you want an air intake, order early, get in line early because there’s like a couple week backlog. we lost a […]
We talk about working with materials that have been annealed, and how the process changes their properties and makes them more challenging to work with. We’re going to try the process again without supports to see how it goes.
We discuss the idea of Mercedes-Benz creating a more affordable version of the Maybach line, similar to how they have the C63 and E63 models. The proposal is for a ‘C Maybach’ that would use a tuned M176 V8 engine, focus on sound dampening and suspension tuning to provide […]
We are going to be investing in more CAD refinements for our existing products. Small refinements to address issues we have seen in our experience processing and supporting over 250 orders. As you may notice we have also printed this in glass fiber reinforced high temperature nylon. This can […]

While new tuning options are exciting they employ a different skill set than normal calibration.
