## Why Switching ECUs Between Prototype and Production Still Costs Controls Teams Time

Most vehicle controls programmes still move through at least two hardware generations: a flexible development ECU for prototyping, then a cost-optimised production part once the design is proven. Every time that switch happens, validation work that was already done has to be repeated — new I/O mapping, new calibration, new sign-off — because the test results from the prototype controller don't automatically carry over to different silicon. For EV, hybrid and off-highway programmes working to tight production windows, that revalidation cycle is one of the most avoidable sources of schedule slip. **The fix is to prototype on the same controller you intend to ship**, which is the specific problem New Eagle's Raptor GCM70 general control module is built to solve, and the kind of toolchain decision EMB Power, as New Eagle's exclusive UK and EU reseller, helps engineering teams make before committing to an architecture.

## What the Raptor GCM70 Is

The GCM70 (part number GCM-5634M-070-1759) is a general-purpose control module in New Eagle's Raptor hardware range, built around an MPC5634M processor with a 70-pin connector, two CAN 2.0B channels, 22 inputs and 19 outputs, and an 8–32 VDC operating range, designed to automotive-grade production standards rather than as a bench-only prototyping board.[\[1\]](https://store.neweagle.net/?p=20641) It's one of several pin-count variants in the Raptor general control module family alongside the GCM48 and GCM196, all sharing the same Raptor-Dev, Raptor-Test and Raptor-Cal toolchain.

### Core specification at a glance

| Parameter | Specification |
| --- | --- |
| Processor | MPC5634M |
| CAN channels | 2 × CAN 2.0B |
| I/O | 22 inputs, 19 outputs across a 70-pin connector |
| Supply voltage | 8–32 VDC |
| Development toolchain | MATLAB/Simulink via Raptor-Dev |

Specification per the manufacturer listing as of 2026; confirm pin-out and environmental ratings against the full datasheet before specifying a module for a client project.[\[1\]](https://store.neweagle.net/?p=20641)

## One Controller Across the Whole Programme

The GCM70's defining feature isn't any single spec — it's that the same physical module is intended to run from first proof-of-concept through to series production. That matters because it removes the hardware hand-off that normally sits between development and production ECUs:

- **Validation carries forward.** Test results captured on prototype hardware stay valid at production sign-off, because it's the same controller, not a port of the logic to different silicon.
- **Fewer variants to support.** One module across prototype and production simplifies spares, documentation and aftersales support, rather than maintaining parallel part numbers.
- **Engineering time shifts to the application.** With the hardware constant, controls engineers spend their time on safety logic, diagnostics and calibration specific to the vehicle, rather than re-qualifying I/O against a new board.

Teams moving from a mixed prototype/production hardware strategy to a single-controller approach consistently describe shorter revalidation cycles as the main benefit — though the actual time saved depends heavily on how much re-qualification a given programme was doing before, so it's worth scoping against your own current process rather than taking it as a fixed percentage.

## The Raptor-Dev, Raptor-Test and Raptor-Cal Workflow EMB Power Builds Around It

The GCM70 is paired with Raptor-Dev, New Eagle's Simulink-based development environment, which lets engineers model control logic with pre-built Raptor blocks, auto-generate code, and flash it directly to the module for hardware-in-the-loop testing — model, flash, test, refine, without hand-written low-level code at each iteration. EMB Power's engineering team then supports the rest of the lifecycle: Raptor-Test for repeatable, documented validation, and Raptor-Cal for calibration, whether that's early bench tuning or secure in-field updates once the vehicle is in service.

As the exclusive UK and EU partner for New Eagle's Raptor and OpenECU toolchain, EMB Power's role isn't just supplying the module — it's the integration work around it: CAN network design, safety interlocks, diagnostics architecture, and helping engineering teams avoid the code-management and calibration pitfalls that show up later in a programme rather than at the bench.

## Getting Started With a GCM70 Programme

A typical EMB Power engagement on a GCM70 programme runs in five stages:

1. **Scoping.** EMB Power's engineering team maps your system's I/O requirements and network architecture before any hardware is ordered.
2. **Initial kit selection.** A GCM70 module, matching connector kit and a Raptor-Dev licence, sized to the programme.
3. **Development.** Simulink models built with Raptor blocks, auto-generated code, flashed and tested on the actual target hardware from day one.
4. **Formal validation.** Raptor-Test integrated for repeatable, documented test cycles ahead of sign-off.
5. **Production ramp.** Because the validated hardware and the production hardware are the same part, scaling order volumes doesn't require re-opening the validation work — EMB Power plans sourcing and delivery schedules alongside the ramp.

## Is the GCM70 the Right Fit?

The GCM70 suits programmes that want one control module to carry from early prototype through to series production, rather than teams who only need a bench-test board. If your project is heading toward volume and you want to avoid re-validating against a second piece of hardware later, it's worth a scoping conversation before the architecture is locked in.
