Calibration / ECUFEF
FEF Performance
Standalone ECU commissioning, inherited-tune diagnosis, drivability and dyno calibration across supported platforms.
Dyno + live ECU read/editStarting at $240/hr
715-441-7100 Family-based • Veteran-owned • Western Wisconsin
Standalone ECU tuning built on fundamentals, data and repeatability.
From no-start commissioning and engine swaps to turbo, supercharger and dyno calibration, FEF Performance focuses on making the hardware, ECU strategy and real-world data agree.

The FEF approach
Platforms change.
Fundamentals don't.
Holley Terminator, Haltech, MoTeC, MegaSquirt, Link, ECUMaster, Syvecs or another supported controller — the menus change, but the engine does not stop obeying the same fundamentals.
FEF starts with hardware truth, trustworthy sensor data, synchronization and measured base timing. Then the fuel model, ignition, torque or boost control, drivability and protection strategy are calibrated from repeatable evidence.

What FEF actually does
A complete path from unknown project to validated calibration.
01
Standalone ECU Tuning
Commissioning, sensor/I/O setup, sync, base timing, fuel, ignition, drivability and protection strategy.
Explore service →02
No-Start / First Start
A structured diagnostic path for fresh builds, swaps and inherited projects that do not currently run correctly.
Explore service →03
Standalone Platforms
Holley, Haltech, MoTeC, MegaSquirt, Link, ECUMaster, Syvecs and other supported systems reviewed by exact hardware and firmware.
Explore service →04
Turbo & Supercharger
Fuel pressure, lambda, ignition, boost control, thermal behavior and engine protections under controlled load.
Explore service →Performance systems in context
Hardware, calibration and controlled load testing.
A mix of licensed automotive imagery and calibration visuals keeps the site useful until additional FEF project photography is approved for public use.

Selected project experience
From older Volkswagen projects to Gen III / IV LS combinations.
The platform list is intentionally broad because the calibration process begins with fundamentals instead of a single software brand.
VW
1990 Volkswagen
R32 swap • GT35 turbo combination.
VW
1997 Volkswagen Jetta
VR6 supercharged combination; long-term no-run project returned to driving condition.
VW
1992 Volkswagen Corrado
3.0-liter custom performance combination.
LS
Gen III / Gen IV LS
Multiple combinations including swaps, cam changes and DOD-delete configurations.
EFI
Standalone & swap control
Holley Terminator, Haltech, MoTeC, MegaSquirt, Link, ECUMaster, Syvecs and other supported controllers reviewed by the actual hardware and scope.
Calibration is a measurement problem
Tables matter. So does the evidence behind them.
A colorful table is not a tune by itself. FEF looks for believable inputs, repeatable operating conditions and the reason a cell or strategy needs to change.
1Log the condition
2Change one major cause
3Repeat the test
4Keep the known-good restore point
A cleaner process
What happens after your project reaches FEF.
The intake happens before the dyno appointment so obvious unknowns do not consume expensive facility time.
01Project intake
Build, ECU, fuel, prior tune, known problems and goals.
02File & hardware review
Identify what changed and what must be proven before load.
03Commissioning
Inputs, outputs, sync, timing, first start and protections.
04Dyno calibration
Fuel, ignition, boost and repeatability under controlled load.
05Validation & handoff
Final backup, limits, remaining recommendations and next steps.
Customer story
A project parked for years returned to the road.
Clear communication matters as much as getting the vehicle running: what was found, what was corrected, what was achieved and what the next limiting factor is.
“I had a 1997 VR6 supercharged Jetta that hadn’t run in over three years. I had honestly given up hope. After dropping it off, the car was alive and driving again within a week. What stood out most was not just getting it running, but taking the time to explain what was fixed, what had been accomplished, and what the next steps would be to take the car to the next level.
Three local businesses. Combined capability.
Calibration, dyno access and project installation support.
Each business remains independently operated while collaborating when a project needs more than one specialty.
Dyno Facility • Holley EFI TuningGFF
Good From Far Garage
Local chassis-dyno access for controlled testing and data collection, plus Holley EFI tuning for Terminator, HP and Dominator-equipped projects.
Dyno-only services$80/hr
Holley EFI tuning$240/hr
Holley package options are available when the project fits a defined scope.
LS Swaps • Install / MechanicalLS MASTER
JP's Performance
Known locally as “The LS Master.”
JP's Performance is heavily focused on LS-based builds: engine swaps, Gen III / Gen IV combinations, DOD-delete projects, supporting installs and project-based mechanical work.
LS swap / engine install servicesQuoted by project
Selected standalone ECU installation and commissioning projects can be coordinated with FEF.
Built local • specialists stay in their lane
One project can move through three specialties without starting over.
The point of the collaboration is not to make three shops look like one company. It is to put the right part of the build in front of the person who does that work every day.

FEF Performance
Family-based. Veteran-owned. Documentation-first.
Performance work gets expensive when assumptions survive too long. FEF is built around knowing what is installed, preserving file history, verifying critical signals and documenting what changed.
01
Verify before load
Critical hardware, sensor values, pressure, synchronization and timing are proven before meaningful power testing.
02
Known-good restore points
Major calibration stages are backed up so the session has a traceable path instead of one overwritten file.
03
Explain the result
Owners should understand what was corrected, what was achieved and what the next limiting factor is.
