TuneBench: ECU Tuning

TuneBench puts a real calibration editor in your pocket. Open a .bin and an XDF definition and edit tables, curves, values and flags with the same tools you use on a laptop. TURN DATALOGS INTO CORRECTIONS • Import a CSV datalog from almost any scanner, logger or wideband app • See the log laid over any table, cell by cell, with sample counts • One-tap presets: wideband VE/MAF error, fuel trims, knock retard • Or write your own math with real channel names, like ([Wideband AFR]/[Commanded AFR]-1)*100 • Filters, minimum samples, strength and max-change limits • Preview every change before you apply it, and undo anything EDIT LIKE A PRO • Color-mapped tables and 3D surfaces • Set, add, subtract, percent, multiply, smooth and interpolate selections • Compare any table against stock • Save versions and roll back anytime • Export your tuned bin to flash with your own tools CHECKSUMS HANDLED • GM P01/P59 (LS1 Gen III) checksums are verified and corrected automatically TRY IT FIRST Open the built-in demo tune and demo log to see the whole workflow, no files needed.
