ECU Compatibility & Setup
MaxxECU Custom Tuning
Custom engine calibration and ZF 8HP transmission tuning for vehicles equipped with a compatible MaxxECU engine-management system. Select your desired tuning services at checkout.
ECU compatibility, firmware, hardware configuration, and access to the current calibration must be confirmed before work begins. Transmission tuning requires compatible MaxxECU 8HP control hardware and firmware.
Available Engine Tuning Services
- Basemap: Initial starting calibration for compatible engine configurations when offered by the selected product variant.
- Existing-Map Modification: Adjustments to a supplied calibration for compatible hardware or configuration changes.
- Full Custom Calibration: Complete engine calibration development covering startup, idle, part-throttle drivability, fueling, ignition, boost control where applicable, and full-load optimization.
ZF 8HP Transmission Tuning
LRW Tuned offers custom transmission calibration for supported ZF 8HP transmissions utilizing MaxxECU transmission control. Whether you're completing an 8HP swap or refining an existing setup, we can help configure the transmission for improved drivability, shift behavior, and overall performance.
ZF 8HP45 / 8HP70 / 8HP90 and other supported 8HP variants, subject to MaxxECU hardware and firmware compatibility.
Standard 8HP Configuration & Tuning
- Initial transmission configuration and communication verification
- Shift points and automatic shift scheduling
- Drive mode configuration where supported
- Engine torque management during shifts
- Torque converter lockup strategy
- Downshift behavior and throttle-blip calibration where supported
- Datalog review and calibration refinements
Transmission tuning requires compatible hardware, firmware, wiring, and a functioning transmission installation. TCU flashing, wiring repairs, mechanical troubleshooting, custom integration development, and additional hardware are not included in standard tuning pricing. Additional labor may apply for initial integration or troubleshooting.

- Engine configuration and MaxxECU model / firmware
- Current base map or ECU file if available
- Injector calibration data, fuel system, and fuel type
- MAP / MAF sensors and trigger configuration
- Turbo / supercharger and boost control details if applicable
- Current modification list and performance goals
- Transmission model (8HP45, 8HP70, 8HP90, etc.)
- TCU hardware and installed firmware
- Current transmission control and wiring configuration
- Current operating status and any known issues
- Intended use and desired shift behavior
For existing-map modifications, send your calibration file and order number to Michael.Leto@lrwtuned.com. Engine and transmission tuning are separate services unless selected together at checkout. Exact service availability, pricing, and included revisions are determined by the selected product variant.
Power figures, where shown, are existing LRW estimates rather than guarantees. Results depend on vehicle condition, fuel, hardware, and testing conditions. Review the pre-tune checklist before calibration. Transmission functionality and available tuning features depend on hardware, firmware, and application compatibility.
