Navigation state-estimation firmware
STM32-based telemetry and state-estimation work using a 15-state Extended Kalman Filter, six-axis inertial sensing, and GPS data at 500 Hz with sub-5 ms processing latency.
Ellis Dynamics
Ellis Dynamics develops specialized automotive engineering and countermeasure systems from a common foundation in embedded electronics, controls, instrumentation, and disciplined hardware testing. Automotive work is moving toward performance calibration, ECU tuning, custom electrical integration, and electrified vehicle systems, while the countermeasure division focuses current development on GPS-denied navigation and maintains resilient communications and predictive tracking as long-range research roadmaps.
Division 01 · Automotive Engineering
Automotive Engineering Performance engineering, ECU calibration, vehicle electronics, and electrified systems.
Ellis Dynamics is transitioning away from a general mobile-mechanic model and toward specialized, engineering-led automotive work that scales with deeper technical capability.
The core direction is performance engineering, calibration and controls, custom electrical systems, and EV / hybrid integration. Routine maintenance and diagnostics remain available selectively by request, but they no longer define the business.
The long-term automotive model is not general repair at scale. It is systems work: instrumentation, calibration, electronics, controls, and engineering decisions backed by measured data.
Performance engineering
Vehicle instrumentation, data acquisition, system evaluation, drivability analysis, and performance-oriented component integration built around repeatable measurement instead of guesswork.
ECU calibration & tuning
Fuel and ignition calibration, closed-loop behavior, telemetry review, and control strategy development. Bench work includes Hardware-in-the-Loop engine simulation and calibration workflows.
Custom electrical & electronics
Harnesses, sensors, modules, fused power distribution, relays, CAN-connected devices, displays, infotainment, and aftermarket integrations designed for reliability and serviceability.
EV & hybrid systems
A developing capability centered on low-voltage controls, BMS telemetry, charging, diagnostics, and future electrified powertrain integration. High-voltage work expands only as equipment, training, and procedures support it.
Automotive engineering record
Current bench work includes a Hardware-in-the-Loop engine simulator using open-source ECU firmware and ArduStim signal generators to exercise ignition and fuel-map calibration workflows in TunerStudio before moving deeper into vehicle-side tuning.
2026 transition
General mobile service concludes at the end of 2026. Ellis Dynamics is shifting toward specialized automotive engineering rather than operating as an on-demand mobile repair business.

- Pricing model
- Scope first. Specialized work is quoted by project rather than sold as open-ended hourly labor.
- Parts
- Customer-supplied or sourced with the project, depending on scope. Parts and labor are separated in the quote.
- Current limits
- High-voltage EV work, ADAS calibration, tire mounting / balancing, alignments, transmission rebuilds, and major fabrication remain outside current service scope.
Engineering Direction
Where the work is headed.
Complex electrical architecture and control systems that general shops can't touch.
Data-driven calibration & tuning
3D fuel and ignition map calibration, boost target control, and transient response tuning. Optimized through wideband AFR logs, knock spectrum analysis, and telemetry. Never by ear.
Custom electrical integration
Spec-built wiring harness design and IPC-compliant fabrication. Aftermarket sensor and module integration, custom CAN bus data displays, and OEM feature retrofits engineered for long-term reliability.
EV & hybrid systems
Low-voltage control architecture diagnostics, BMS telemetry integration, charging equipment installation, and future electrified powertrain development as equipment and procedures support it.
Division 02 · Research & Development
Countermeasure development is centered on resilient state estimation and GPS-denied navigation, with capabilities advanced only as bench results support them. Hardened data links and predictive target tracking remain long-range roadmap programs rather than current near-term build priorities.
Inertial navigation & state estimation
Current development centers on STM32-based state estimation, Extended Kalman Filtering, and six-axis inertial sensing for navigation through degraded or denied GPS conditions.
ACTIVE DEVELOPMENTHardened data links
Resilient communications architecture designed to maintain telemetry and coordination links under active RF jamming.
LONG-RANGE ROADMAPPredictive target tracking
Multi sensor fusion across EO and IR with precision feedforward gimbal control, providing the foundational tracking layer for counter UAS platforms.
LONG-RANGE ROADMAP
01
Modular Inertial Navigation Unit (INU)
Standalone inertial dead reckoning hardware that keeps platform position awareness through complete GPS denial.
02
Predictive Tracking System
Future multi-sensor state estimation and gimbal-control research intended to build a predictive tracking layer after the navigation program is substantially matured.
03
Integrated Countermeasure Architecture
Future integration of resilient navigation, communications, and optical tracking into a common test architecture after the individual subsystems are independently validated.
