The hardware

One board. The whole platform.

Every year, every engine, stock to 1000 HP — 6-cylinder sequential fuel and spark, onboard wideband, knock and MAP, and the factory optical trigger handled directly. Here's everything it does.

Under the hood

Fuel & spark6-cylinder sequential injection + ignition, COP-ready, wasted-spark and coil-pack conversion support for the older cars
TriggerReads the factory optical crank sensor directly. This is the part that makes 3S standalone swaps hard, and it's handled. Aftermarket crank-trigger ready.
OnboardWideband AFR controller, knock control, MAP + baro, SD-card datalogging, USB + dual CAN, wireless tuning
Talks to your carDual CAN bus for modern digital dashes, gauges and telemetry — plus a bridge to the factory module network, so your ECU can share data with the rest of the car
Tuner featuresBoost control, 2-step launch, anti-lag, flat-shift, flex-fuel, EGT, nitrous/meth outputs, gauge/CAN dash feed
Two connectorsA — factory plug-and-play (stock cars). B — expansion for all the extra features (built cars).
Fits your yearThe factory connector changed across the platform's life — your kit includes the correct generation adapter for your exact car, so it's a true plug-in. Just tell us the year.
Tuning softwareOur own tuner — live tuning link, per-circuit health dashboard, one-click diagnostic reports, datalog review
One board, three generation adapters, the whole platform. 1991–93, 1994–97, and 1998–99 used different factory ECU connectors. We build the matching adapter for each, so the same ECU drops into any 3000GT, Stealth, or GTO. The firmware is ours, written from scratch for these cars.

The complete capability sheet

The full list. If it's not on here, don't assume it — ask us.

Engine control

Injection6-cylinder full sequential. High-impedance injectors natively; peak-and-hold for low-impedance race injectors — configured in software, no hardware change
Ignition6 channels: factory coils, wasted-spark conversions, smart coils, or full COP — with onboard high-energy ignition drivers, no external ignitor boxes
Output supervisionEvery injector and ignition channel reports open-load, short, and over-temperature individually — the ECU knows a dead coil circuit by cylinder
TriggerReads the factory optical crank/cam sensors directly — the hard part of this platform. Aftermarket crank-trigger ready. Trigger self-capture on first crank validates your car's exact pattern before spark is ever trusted
BoostClosed-loop boost control with overspeed and slew-rate safety cross-checks
IdleDrives the factory ISC stepper directly + PWM idle-valve output for conversions
Race features2-step launch control, flat-shift clutch input, spare PWM outputs for meth / VVT / second boost stage / nitrous control
Flex fuelGM ethanol-content sensor wires straight in — blend-aware fuel and spark, sensor-fault fallback

Sensing

WidebandOnboard controller — Bosch LSU 4.9 plugs into its own dedicated connector. Heater managed with proper level-shifted drive and health feedback; sensor diagnostics included
KnockDedicated knock processor with differential sensor input (rejects harness noise), frequency-windowed detection per cylinder-count, feeding spark-retard strategy
MAPAbsolute manifold-pressure sensing to ~2.9 bar (≈27 psi boost) + external MAP input above that + barometric reference
Factory sensorsCLT, IAT, TPS, battery voltage — every input filtered, clamped, and biased for the factory sensors
Expansion sensing7 spare protected 0–5V analog inputs (oil pressure, fuel pressure, trans temp, whatever your build needs) + EGT expansion port
Every input protectedSeries limiting, over-voltage clamps, and TVS on every harness-facing pin — a shorted sensor or a miswired pin does not kill the ECU

Outputs & vehicle integration

Vehicle loadsFuel-pump driver, dual fan outputs (PWM-capable), A/C clutch control, check-engine lamp, factory tach feed — all through protected, fused, flyback-clamped driver stages
General-purpose2 spare protected low-side outputs (shift light, solenoids, relays)
CommsDual CAN (digital dash / telemetry + expansion), OBD-II port with K-line, dedicated tuning link
Factory modulesReads factory module fault codes (ABS, SRS, climate) over the diagnostic bus and folds them into one report
LoggingOnboard SD-card datalogging + a flash blackbox fault log that survives power loss
TuningUSB connection + our own tuner app: live tuning, per-circuit health dashboard, one-click diagnostic report, datalog review

Survivability

Power protectionReverse-battery protection (MOSFET, not a lossy diode), ISO 7637 load-dump clamping, survives cold-crank voltage sag without resetting
Sensor railsTwo independently protected 5V sensor feeds — a shorted sensor on one rail can't brown out the other
Firmware safetyWatchdog + brown-out supervision, graduated limp modes — a failed sensor degrades the tune, it doesn't strand the car. Every fault path raises a logged, reasoned DTC
TestingFirmware developed against hundreds of automated tests and a hardware-in-the-loop rig simulating the running engine — before it ever touches a real car

Two ways to tune it — your call

Most standalones lock you into one company's proprietary software. MANA does the opposite: it speaks the industry-standard tuning protocol, so you can use the open software you already know — or the tuner we built around this platform. Same ECU, same tune file, your choice. No lock-in either way.

Open tuners
LibreTune, TunerStudio-compatible
MANA talks the standard TunerStudio protocol, so free, open tuning software like LibreTune connects to it directly — the same class of tools the Speeduino and rusEFI world already uses every day. Live VE / lambda / timing tables, gauges, datalogging, auto-tune. Nothing proprietary between you and your own tune, and no software licence to buy.
MANA Studio
included with every unit
Our own tuner, built specifically for this platform. Everything the open tuners do — plus the part they can't do: the full key-on pre-drive health check, harness self-test, per-circuit diagnostics, actuator click-test, and the one-click reasoned fault report. The diagnostic suite is what makes this ECU different, and it lives here.

How it works

1. ReserveTell us your year, model, transmission, and build level. Pay the flat founding price through Square. Your spot number is locked from the moment you reserve.
2. We build your unitYour ECU is assembled, loaded with the validated tune for your exact configuration, and run through the full self-test battery on the bench. Your generation adapter is hand-built and continuity-tested pin by pin.
3. Plug it inUnplug the factory ECU. Plug MANA in through your adapter. Turn the key — the pre-drive health check runs, tells you the harness is good, and you start the car. Nothing gets cut. The stock ECU goes on a shelf, not in the trash.

What's in the box

Wideband AFR needs a Bosch LSU 4.9 sensor at the exhaust — the controller is on the board, the sensor itself isn't included (they're a wear item; any LSU 4.9 works and screws into a standard O2 bung). If you want one in the box, say so in the notes and we'll quote it with your kit.
