PORSCHE TUNING / KEITH FIELDS

Porsche performance tuning.
Modern & vintage.

Custom calibration for supported modern Porsches and vintage engines with standalone management. Work directly with me on throttle response, drivability and useful power, with the tuning method chosen for your car and its condition.

Start with your installed engine management below. The 911 Turbo S results and 964 engine projects show examples of my work.

START WITH YOUR PORSCHE

Which route fits your car?

Looking for in-person support? Orange County road tuning and customer-arranged dyno sessions are available by agreement.

BEFORE BUYING EQUIPMENT OR A TUNE

What I need to review your Porsche.

Modern factory ECU

Send the year, model and trim, market, transmission, fuel and installed parts. Include the Accessport part number, current map and any warning lights. Engine and PDK tuning are separate compatibility and scope checks.

Vintage or standalone engine

Send the engine specification, ECU model, injectors, fuel pressure, throttle arrangement and available wiring documentation. Tell me whether it runs, who installed the system and what needs improving.

Remote or in person?

A running, mechanically ready car with suitable logging may be a remote-tuning candidate. Initial setup, unresolved faults or missing instrumentation may require hands-on work. Include your location and any available shop or dyno facility.

You can start with the basics. Tell me what you know about your car →

FROM THE RESULT TO YOUR PROJECT

Porsche projects and documented results.

911 / COBB calibration

510 → 543 hp

The 2014 Turbo S reports record a 33-hp increase in peak output during the April 17, 2019 session. The 2018 Turbo S archive separately records 624.9 hp on 93-octane fuel.

I use your exact model, software, fuel and installed parts to scope your tune—not another car’s peak figure.

Macan GTS / COBB

374.0 hp

The November 29, 2021 individual report records 374.0 hp at 6,178 rpm for the 2016 Macan GTS.

A road car’s calibration needs to account for usable response as well as full-load performance. Engine and PDK support are reviewed separately.

Discuss a supported COBB application →

Vintage 964 / Kinsler

My experience includes an Emtron Shadow 8 cable-throttle 4.0-liter engine, a separate large-cam MaxxECU build and a street-cam MoTeC build.

These projects start with the engine specification and installed management system. Throttle configuration, injector setup and fueling are part of the calibration brief.

MODERN PORSCHE / COBB ACCESSPORT

A tune for your Porsche.

I offer custom tuning for supported Porsche COBB applications. We start with your exact vehicle, Accessport, fuel and hardware, then agree on the right approach: remote e-tuning, a dyno session or further setup work.

911

COBB lists selected Carrera, Turbo and GT3 applications across multiple generations, including 991 and 992. Generation, trim, model year and ECU support determine fitment.

Boxster & Cayman

Selected 987.2, 981 and 718 applications, including specific 4.0-liter variants. Confirm your exact model and device before ordering.

Macan & PDK

Selected Macan applications and PDK products are available. PDK transmission support is checked separately from engine tuning.

Check device fitment in COBB’s Porsche catalog. A catalog listing does not by itself confirm custom-tuning access for every ECU or software version. I verify your combination before payment.

AIR-COOLED PORSCHE / RESTORATIONS & RECREATIONS

Preserve the character.
Refine the response.

My vintage Porsche experience includes supporting Kinsler products on 964-based 4.0-liter engines and consulting with Ed Pink Racing Engines on engine-management calibration. These projects bring the engine, throttle system, fuel delivery and ECU together as one working combination.

For a restoration or recreation, the conversation starts with how you want to use the car. A responsive road engine and a competition-focused combination can need different behavior. I consider the engine specification, drivetrain, tires and intended conditions alongside the power target.

Kinsler throttle systems

Calibration support for the installed induction and throttle arrangement, including individual throttle bodies. Cable linkage and drive-by-wire require different setup work; I establish which system is fitted before defining the scope.

Drive-by-wire integration

Pedal and throttle setup, response and the available control strategy are considered together. The aim is a predictable relationship between your input and the engine’s response.

Fueling & drivability

Injector configuration, starting, warm-up, idle and transient fueling are part of the work. Advanced fueling strategies are selected around the engine, sensors, fuel system and ECU capabilities.

FROM MY AWD TUNING DYNO ARCHIVE

Porsche experience.
Recorded on the dyno.

I personally tuned all four of these Porsches through COBB during my work at AWD Tuning. Most used bolt-on modifications; the dated Mustang Dynamometer reports below record their individual results. Each figure below is the report’s maximum power with its stated WCF correction. They are individual results, not a promised output for another car.

2014 Porsche 911 Turbo S peak horsepower comparisonApril 17, 2019 Mustang dyno reports: baseline 510 horsepower; revised tune 543 horsepower. Bars start at zero and use the same scale to 600 horsepower. These are separate peak values, not full power curves.Recorded peak power (hp)Baseline510Revised tune5430600 hp
2014 911 Turbo S · April 17, 2019 · Corrected Mustang chassis-dyno peak values. A 33 hp increase in recorded peak output; the bars do not reproduce the full power curves.

2014 911 Turbo S

Baseline: 510.0 hp
Revised tune: 543.0 hp

The paired reports record a 33.0 hp increase in peak power during the same day’s session. Peak values occur at different engine speeds; this is not a gain measured at one fixed RPM.

2002 911 / 996

October 1, 2020
Recorded maximum: 563.8 hp at 6,718 rpm

I calibrated this 3.6-liter 2002 Porsche 911 through COBB.

2016 Macan GTS

November 29, 2021
Recorded maximum: 374.0 hp at 6,178 rpm

A 3.0-liter Macan GTS example from the archive, extending the Porsche experience beyond the 911.

2018 911 Turbo S

April 6, 2026
Recorded maximum: 624.9 hp at 6,292 rpm

A 3.8-liter 2018 911 Turbo S, tuned through COBB on 93-octane fuel.

Results are from the original AWD Tuning Mustang Dynamometer reports and dated to each run. These are corrected chassis-dyno figures, not factory crankshaft ratings. Hardware, fuel and test conditions affect the result; compare each car within the context of its own setup.

HANDS-ON PORSCHE EXPERIENCE

Different systems.
The same attention to detail.

964 4.0 / Emtron Shadow

I calibrated this Ed Pink 964-based 4.0-liter engine with Kinsler cable throttle and Emtron Shadow 8 management. This particular build used cable throttle only.

Explore Emtron tuning →

MaxxECU / Kinsler DBW

I tuned a large-cam Porsche 964 engine using MaxxECU and Kinsler drive-by-wire, refining injector setup, fueling and throttle behavior.

MoTeC / Porsche integration

I also tuned a different Porsche 964 engine with street-sized cams, using MoTeC management and Kinsler dual drive-by-wire control.

Explore MoTeC tuning →

The MaxxECU and MoTeC projects were two different 964 engines: the MaxxECU build used large cams, while the MoTeC build used street-sized cams. I calibrated both, tailoring the approach to each engine’s specification and intended driving experience.

PLAN YOUR ENGINE MANAGEMENT

From the engine build to the tuning session.

My 964 experience spans multiple engines with both cable-operated and drive-by-wire throttles. The installed throttle hardware, ECU and engine specification determine the work; a DBW conversion is not assumed as part of a tune.

Emtron setup and logging

Identify the installed Emtron model and gather Emtune logs, sensor information and throttle-system details for your engine.

Read the Emtron guide →

MaxxECU setup and logging

Prepare the MTune calibration and native logs, with wiring records and notes on starting, idle and throttle response.

Read the MaxxECU guide →

MoTeC setup and logging

Confirm the ECU, installed package and access details, then collect logs and documentation for the connected systems.

Read the MoTeC guide →

OWNERS, RESTORATION SHOPS & ENGINE BUILDERS

Bring the project together.

I work directly with owners and shops to plan calibration, resolve engine-management issues and coordinate dyno sessions. Worldwide travel tuning is available by arrangement. ECU sales and packages can be scoped around the project.

  1. Send the specification: chassis, engine displacement, build details, induction, throttle system, injectors, fuel and ECU.
  2. Describe the starting point: running condition, current calibration, wiring documentation, available sensors, logs and the behavior you want to improve.
  3. Plan the session: your location, builder or installer, dyno facilities and whether you need remote support or an in-person visit.

Porsche standalone projects, equipment and travel are individually quoted. Pricing and delivery timing are agreed for your scope before payment.

PORSCHE TUNING FAQ

Choose the right route.

How much does Porsche tuning cost, and what does the quote include?

The quote depends on your exact Porsche, ECU, fuel, installed hardware and the work required. A supported factory-ECU calibration and a vintage standalone commissioning project have different scopes. Send the setup before choosing a service or buying equipment.

I confirm the calibration work, revision allowance and any required hardware or licenses in your quote. PDK tuning, diagnostics, dyno access, in-person work and travel are discussed separately where applicable. Ask for a Porsche setup review without paying →

Can my Porsche be tuned remotely, or do I need a dyno session?

I review the installed ECU, current running condition and available logging equipment before agreeing on the route. Remote tuning uses the requested logs and revisions. A project needing setup, troubleshooting or instrumentation may need the car and a suitable facility available for in-person work.

For a vintage engine, include the builder, ECU model, throttle system, injector details, wiring documentation and any existing logs. For a modern Porsche, include the year, trim, transmission, market, Accessport details, fuel and modifications. Compare services and prepare your information, or plan a coordinated dyno session.

Can a vintage 964 use the same COBB service as a modern Porsche?

No. The vintage engines described here use a separately installed standalone ECU. Modern COBB tuning depends on a supported factory ECU and matching Accessport. Send the installed system details so I can identify the right service.

Do I need drive-by-wire for a Kinsler-equipped engine?

Not necessarily. My experience includes cable-throttle and DBW configurations. The appropriate setup depends on the installed hardware and your goals; a DBW conversion is a separate project, not an assumed part of a tune.

Can you support an engine builder or restoration shop?

Yes. I can work with your builder or shop on engine-management planning, calibration and dyno coordination. Send the specification and available facilities so we can define responsibilities and the session plan.

Does a COBB product listing guarantee you can custom-tune my car?

No. I confirm the exact year, trim, market, transmission, ECU software and device support before taking payment. PDK support and licensing are checked separately.

What will the engine make?

Output depends on the complete engine, fuel and test conditions. We agree on useful performance goals and evaluate the response and drivability as well as the dyno result.
