Window (samples)
Spacing for the stability check (about 0.5 s at 20 Hz = 10)
Δload max (%)
Largest permitted TPS change within the window
ΔRPM max
Largest permitted RPM change within the window
Load min (%)
Above this load only the normal stability rule applies
For load 1–2 % it additionally requires < 4500 rpm and ΔRPM ≤ 300; for load 0 % < 1800 rpm and ΔRPM ≤ 200. (Keeps overrun out.)
Map exportfor▾⚠ Caution, experimental!
Generate corrected PowerCommander, Rapid Bike and IAW16M maps from your lambda log, or export CSV files. The output file is verified before download.
Measurement confidence
Applies to all formats (PVM, DJM, MPP, CSV and IAW16M preview). Only measured samples assigned directly to a cell count. Cells below the threshold retain the original value (or 0% correction).
IAW16M · Source BIN
An original .bin (64 KiB) oder ein ZIP mit einer BIN auswählen. Für kompatible IAW16M-Dumps werden Kennfeldposition, Drehzahlachse, TPS-Rohwerte und Delta Fuel geprüft. Mit geladenem Lambda-Log wird die calculated Base Fuel correction angezeigt. Der Download erstellt eine neue .bin und überprüft die vollständigen 65.536 Bytes: ausschließlich Base Fuel darf verändert sein.
No BIN loaded yet.
TPS → degrees conversion
0 % and 100 % TPS in the MD-Lambda-View CSV correspond to the min and max angle of the injection map.
Correction parameters
Glättung/Ausreißer-Filterung erfolgt beim CSV-Einlesen. Nur Zellen mit genügend Messpunkten werden korrigiert. Die Berechnung begrenzt die Änderung auf MAX_ÄNDERUNG. Monotonie wird nur in gemessenen Zellen und innerhalb dieser Grenze berücksichtigt. Die ursprüngliche BIN im Browser bleibt immer unverändert; der Download enthält eine neue Kopie.
Rapid Bike EVO · current map
Upload the .mpp file currently used by Rapid Bike. For a clearly recognized Injection map, lambda corrections are added to the existing RB units. All other file content is preserved. For two Injection maps, you can choose cylinder 1, cylinder 2, or both. Each cylinder's existing trim map remains its starting point, and unselected maps are left unchanged.
RPM and TPS grid: Read from your uploaded MPP file.
No MPP loaded yet.
With “Both”, the same correction calculated from the lambda log is added to each cylinder’s own current map. Make sure the log is representative of the selected cylinders.
Correction parameters
Calculation: deviation to target λ in %, divided by “% fuel per RB unit”, clamped to ± the max change, written additively (as integer) onto the base map. Column 0 % is left untouched (overrun). The target λ values come from the 2D app preset (see below: “Target λ per TPS zone”).
Custom template
Load a .pvm file from your PowerCommander software. For PVM, axes and the fuel map are detected dynamically. Export adds the calculated percentage correction to the existing primary fuel map, preserving the remaining data. If multiple separate primary maps are present, export remains disabled. For DJM, axes and block layout are read; export adds the correction to the existing fuel map (with two cylinder maps, according to your selection) and leaves all other data unchanged. DJM output is new – please check it in the PowerCommander III software before flashing. The file stays stored in your browser until you remove it.

PowerCommander · correction limits
Locked cells (0 % throttle, idle below the rpm limit) keep their original value. For minimum samples, the stricter value of this section and the general settings applies; for PowerCommander, the maximum change is set only here.
Target λ per TPS zone
TPS boundaries between zones
Linear interpolation between TPS values. These targets apply only to the export (2D, 3D and IAW16M flash); the 2D app has its own targets that stay untouched.
