This software is designed to read binary ROM images used in Bosch Digital Motronic Engine-management (DME) systems found in Porsche, BMW, Volvo, SAAB, and other European vehicles. It is user-extensible via customized spec files, and includes features for ferreting out the relevant locations that the fuel-injection maps are based on.

GM ECM
For controlling your EFI-converted Datsun 1200, you can use a General Motors (GM) ECM. The Electronic Control Module (ECM), also known as Electronic Control Unit (ECU),varies by year. Most have varying models of standard EPROM memory, while a few newer ones have built-in Flash memory. They can control anything from old 4-cylinder engines to the newest V8 engine designs.

TunerCat
A product named C.A.T.S. Tuner is used to program/control the GM ECU. It works with certain 1984-1997 GM ECUs, and can modify the spark and fuel tables, as well as control certain on/off switches.
Get an ECU for 94 - 95 LT1 cars, it has built in Flash.
Parts needed
- Used GM ECU from wreckers ($25-up)
- GM EFI components:
- GM sensors: Oxygen sensor, Air temp, water temp, MAF sensor (some models), TPS or MAP sensor
- GM fuel injectors
- OR, Edelbrock system for GM ECU
- Tuner program ($70, free 30-day trial)
- ECM definition file to match the specific GM ECU ($20)
- For older ECUs, get any generic EPROM burner. For example, Pocket Programmer ($250) and EPROM Eraser ($57)
- 94 - 95 LT1 cars don't need this, they have built-in Flash memory
- But they need an ALDL interface cable (?)
- 94 - 95 LT1 cars don't need this, they have built-in Flash memory
- Ground strap to protect electronics while flashing/programming ($5)
A product called Romulator plugs into the ECU and and into your laptop to control the ECU.
Real Time Tuner
RT Tuner allows programming while the engine is running. Flash based ECMs do not have a removable EPROM there's no way to connect an emulator to these ECMs so you can't do real-time tuning on these cars.
- All the parts above (but won't work with Flash ECU)
- RT Tuner ($100)
- [Romulator] or Ostrich or AutoProm
