Why it exists

I own a '92 Stealth R/T. The factory ECUs in these cars are dying of old age, there's no replacement, and it's one of the worst platforms to go standalone on — the optical crank sensor alone stops most people. The usual path: a generic ECU, a custom harness, and one of the few tuners in the country who knows a 6G72.

MANA is the opposite of generic. It's built for these cars specifically — the factory connectors, the optical trigger, the ISC stepper, the exact failure modes — so a bone-stock SOHC and a built twin-turbo are the same job to it.

What makes it different
A1

Adapter, not a rewire

Your year's factory ECU plug mates through a generation adapter — 1991–93, 1994–97, or 1998–99. Nothing on the car gets cut. Unplug it and the stock ECU goes right back in.

A2

Runs before it's tuned

Each unit ships loaded with a validated tune for your engine and build, and bench-tested before it leaves. You don't need a dyno appointment to start and drive.

A3

One board, every build

High-Z or low-Z injectors, factory coils through full COP, E85 and flex, boost and 2-step — configured in software, not swapped in hardware. The stock car and the 900whp car run the same board.

A4

Finds its own faults

A key-on self-check that reports by factory pin number — open injector, corroded ground, dying coil circuit — and logs the intermittent gremlins even when they self-clear.

The diagnostic suite

It finds the broken wire before you leave the driveway.

These cars are 30+ years old — more are sidelined by harness gremlins than broken engines. Turn the key and MANA runs a full self-check in about two seconds. When something's wrong it names the actual wire and the factory pin, not a vague code.
