START WITH YOUR GOAL
You don’t need all the answers yet.
Choose the closest match and we’ll help you take it from there.
Factory ECU tuning
A good starting point for a running vehicle that needs a supported factory ECU flash or calibration review.
Dyno tuning & testing
Start with a baseline, or plan a calibration session around your engine, ECU and current setup.
Standalone ECUs & wiring
Get help choosing a Link ECU, matching the harness and sensors, and planning installation and calibration.
Swaps & first starts
For a fresh swap, an inherited project or a no-start that needs structured troubleshooting before tuning.
01 / THE CAPABILITIES
A street car, a fresh swap, or a build that needs sorting out. Start with what you need—we’ll work through the details with you.
01 ↗Factory ECU flashes and project-specific calibration. Dyno-supported tuning when you want to measure the changes.
02 ↗Establish a baseline, log the run, and see how the vehicle responds under load. Local Dynojet testing with Good From Far Garage.
03 ↗ECU selection, harness work, sensor setup and calibration—from the first connection to the finished system.
04 ↗Fresh engine swaps, unfinished projects and no-start troubleshooting. Get a clear plan for the work ahead.
02 / THE FEF APPROACH
Good tuning starts before the first edit. We review the setup, check the calibration, and make changes for the actual vehicle.
Flash tuning is available without a dyno. For builds that need measured results under load, we plan dyno testing into the project.
How your project works →Your engine, ECU, modifications, current condition and goals.
Review the hardware, signals and base calibration before making changes.
Make controlled adjustments, review the logs and verify the response.
Understand the work completed, the current limits and any follow-up needed.
03 / FROM THE BUILD RECORDS
Ongoing calibration · Break-in and follow-up pending
Read the project notes →Recorded improvement: +54 whp. This is an ongoing build, not a final calibration result. Supporting dyno sheets and test-condition details are pending.

BEFORE WE TALK
Every vehicle is different. Here’s what to expect when you start a conversation with FEF.
More questions answered →No. Tell us about the vehicle, what currently works and what you want to improve. The first conversation helps establish a sensible next step.
Factory ECU tuning and supported read/write work are available. Exact support depends on the vehicle and controller. Check compatibility or bring the details to your consultation.
No. Flash tuning is available without a dyno. We discuss dyno testing when measured results under load would help the project.
A 30-minute conversation about the project, possible options and next steps. FEF confirms the appointment with you. Tuning, parts, installation and dyno time are quoted separately.
