Description
DigiTune GTS — Tune faster. Tune better.
Getting the most out of your engine shouldn’t mean hours staring at logs and spreadsheets, or making educated guesses. DigiTune GTS takes your datalogs and shows you exactly what your engine needs — so you spend less time tuning and more time driving.
See what your engine is actually doing
GTS loads your log files and maps, calculates the fuel requirement at every point in your log, and plots the results on a graph for each row and column of your fuel table. Instead of trying to mentally connect what happened on a run to where it sits in your map, you can see it all clearly in one place. The software shows you which cells need attention and by how much — and adjustment is as simple as clicking and dragging the table curve to match the data.
No more cross-referencing logs and tables in separate windows. No more guesswork.
What you can tune with GTS
- Fuel tables — the core of GTS. It processes every run you’ve logged and builds an accurate picture of how your engine is breathing across the rev range. Dial in your fuelling with confidence.
- VE table column alignment — GTS can reveal where your engine’s resonance peaks actually sit, letting you align your table columns properly to improve table accuracy. This is something that’s nearly impossible to spot in real-time.
- Idle and boost control — use logged data to refine idle and boost control duty cycles through calculated plots rather than relying on trial and error.
- Knock thresholds — see raw knock sensor data plotted against RPM, with ECU-detected knock events highlighted. Set your background noise thresholds based on what’s actually happening, with no guesswork.
- Ignition timing — use knock data to adjust timing tables rather than repeatedly relying on real-time correction.
- Temperature compensation — load warmup logs or multiple logs from different conditions and GTS will help you account for intake air temperature and coolant temperature effects across the whole map.
