Complete Toolset for Engine Calibration

Smart Mappacks & Auto-Detection

Access precise, hand-verified maps for individual ECUs. If a mappack is missing, our advanced heuristic sniffer automatically identifies core maps.

Advanced Math & Editing

Modify grids with precision using our dedicated math toolbar. Easily apply percentage scaling, data smoothing, and intelligent extrapolation.

Analytics & Visualization

Verify your tune instantly. Visualize your modifications with interactive 3D surface plots, Limiter Trace graphs, and an integrated Virtual Dyno.

Your Secure Cloud Tuning Vault

Professional tuners need reliability. Your projects are securely backed up, instantly analyzed, and accessible from home, the garage or the dyno.

Smart ECU Detection

Upload a binary and our server instantly identifies various part numbers before you begin.

Cross-Device Workspace

Never lose a map pack to a crashed hard drive. Start tuning on your home PC, finish on your garage laptop.

Permanent Access

Use Tuning Credits to unlock hardware/software families. Once unlocked, your specific project and map layouts are yours forever.

Dedicated File Protection

We protect your project files so you can focus on the calibration. Never worry about a crashed workshop laptop taking your original reads with it again.

More Maps Found For EDC16

  • MAF Sensor Linearization curve added - translates MAF sensor voltage into kg/hr mass air flow.
  • Injection Quantity Limiter (Air Temperature) map added - scales fueling based on air temperature.
  • Boost Correction map added - adjusts boost pressure based on air temperature.
  • Expected Fuel Temperature map added - estimates fuel temperature based on injection quantity and engine speed.
  • Idle RPM Setpoint (Moving) curve added - defines the target idle RPM when the vehicle is in motion.
  • Idle RPM Setpoint (Stationary) curve added - defines the target idle RPM when the vehicle is stationary.
  • Idle RPM Setpoint (Pressure vs Temperature) map added - defines the target idle RPM based on barometric pressure and coolant temperature.

Dynamic Start of Injection & Dynamic SOI Selector Sniffing Bug Fix

  • Dynamic Start of Injection map had wrongly defined axes and is now successfully found.
  • Dynamic SOI Selector map had wrongly defined axis and is now successfully found.
23/08/2026

Search Bar & Experimental Light Theme

  • Added a search bar to allow you to search maps by their name or tags to make navigating easier.
  • Added an experimental light theme for better visibility in bright environments.

Security Patch & EDC16 Map Sniffing Bug Fixes

  • Fixed some security issues.
  • BIP SOI Correction is now being found properly, previously there was a typo in the code preventing it from being found.
  • Gear-Based Start of Injection maps were previously mis-named as "Start of Injection".
  • Start of Injection maps were not being found due to unfinished code.

Bug Fixes, UI Updates & New Smoothing Mode

  • Further session-related bugs fixed.
  • Currently selected map is now highlighted so you wont get confused anymore. Toolbar colour-coded and labelled so you know what each button does. Added undo/redo buttons for those that don't use keyboard shortcuts.
  • New smoothing mode added for more predictable behaviour.
15/08/2026

Dyno Graph and Limiter Trace Chart Bug Fixes

  • Dyno graph now has a drop-down menu to select a different engine platform if you believe the tool chose the wrong one for you.
  • Trace Limiter chart not displaying EDC16 units correctly now fixed.
  • Additional map selector added - this one is for the Torque to Injection Quantity map.
  • Updated virtual dyno calculations, it now has an AVF (PD130) reference on top of the existing ATD (PD100) reference. Leading to more accurate torque estimations.

Projects Page Update. Last Session Handling & Dyno Graph Bug Fixes

  • Projects page has updated design and functionality.
  • Fixed issue where last session handling did not respect user settings.
  • Fixed issue where the dyno graph did not update correctly under certain conditions.
  • Fixed issue where the dyno graph reset the units from imperial to metric (default) after each update of the graph.
