I've been quietly building this for months, and it's now stable enough for the first semi-public alpha testers.
This is a single-file, zero-dependency Python app with a clean dark theme that's genuinely easier and faster to use than WinOLS or TunerPro for everyday work.
What it does (and does well):
Launch Control
Full slider control over RPM thresholds, ignition retard, NLS cut duration, pedal thresholds, temp gates, and hard cut limiter.
Ignition
KFZW, KFZW2, KFZWOP, KFZWMN, KFZWMS, warm-up delta maps, cranking map — all with inline axis editing (just double-click the headers).
Fueling
LAMFA (shown as AFR), KFLF enrichment, KFLBTS/KFFDLBTS component protection, KFDLBTS, KFKHFM MAF correction, full transient enrichment/lean-out maps.
Boost & Load
LDRXN, LDRXNZK, LDORXN, LDPBN, KFLDHBN (pressure cap displayed in psi gauge).
Torque
KFPED, KFMIRL, KFMIOP, KFTARX + IAT correction.
Injector Calibration
KRKTE with built-in sizing calculator, TEMIN/TEMINVA, TVUB voltage correction curve.
MAF
KFMLDMX airflow ceiling, full 256-point MLHFM linearization curve, MLOFS offset.
Cold Start / Warm-up
Complete KFWKSTN, KFWKSTT, KFNSA, KFLANS, KFFWL, KFLASWLR — full post-start and warm-up fueling.
Overrun / Pops & Crackles
KFTVSA cut delay, KFNWEGM reinstate RPM, CWSAWE, plus the full reinstate cluster. Dedicated pops/crackles tab.
Rev / Idle
NMAX/NMAXF/NMAXOG/VMAXNB, idle RPM curves (NLLM/NFSM variants), KFMRES torque reserve, post-start/cat-heating idle maps.
Diagnostics & Euro-Byte
ESKONF bitfield editor (ZUE/EV/SLP/SLV/etc.), CD* toggles, CWKONLS lambda config.
Boost Control / LDR
SDLDR* thresholds, KFLDIMX, KFLDRL linearization, etc.
Port Calibration
One-click map/scalar migration between bins — pick source + target, tick what you want to copy, done.
Highlights:

Pure Python — runs anywhere Python does
One single file (no install, no dependencies)
Clean dark UI built for speed
Inline axis editing makes map work dramatically faster
Designed by a tuner for tuners

This is the alpha — it's already very usable, but I'm looking for serious ME7.5 guys who want early access and are willing to provide feedback as I finish the final polish.
Serious inquiries only. If you're tired of clunky Windows-only tools and want something modern, lightweight, and actually pleasant to use, this is it.
DM me if you're interested.
