Dyno Tuning

AMS ECU Calibration Overview

Solid and accurate principles are the basis on which we have built our calibration knowledge. Using a careful and deliberate approach to each engine management solution we are able to extract the most horsepower, driveability, and consistent results out of virtually ANY system. Our experience has led us to tune many race winning cars, which exceed expectations on motor reliability, easily gaining their owners 50-100% more time than expected on a single engine package. Our ability to offer a linear driving experience, an amazing high horsepower car, a daily driven vehicle, and literally everything in-between means that we can tailor the results of your calibration to meet your specific needs.

Dyno Tuning Rates

Factory ECU Calibration is presented as a flat rate fee for your first visit to AMS. Generally, most cars are finished within the 2 hours included in the flat fee. Additional time, if necessary, will be billed at $300/hr. Any subsequent returns to our dyno will vary based on the amount of work needed for the new tune, please call or email for a quote.

AMS Tuning Appointments
Tuning Appointment Deposits

Monetary deposits are required for all dyno tuning appointments with AMS tuners. Due to the overwhelming number of cars tuned daily here at AMS, we must adhere to a strict schedule to ensure all customers have the greatest level of support. Your deposit will ensure you are guaranteed an appointment with AMS to have your vehicle dyno tuned. A deposit of $200 for standard ECUs and $300 for standalone engine management systems is required to finalize an appointment setting.

Appointment Cancellation & Late Arrivals

With this strict schedule we must adhere to, we ask that our customers help us maintain this level of service by having their cars fully prepared for tuning beforehand and arriving on time for their dyno tuning appointment. Customers who cancel or reschedule appointments within 7 calendar days of their appointment will not be eligible for a deposit refund. Arriving more than one hour late for an appointment can possibly invalidate an appointment as well, which would also void a deposit refund.

Pre-Dyno Inspection

Another important part of having your vehicle tuned is to be sure that the intake tract is free of leaks both when in positive boost pressure and under engine vacuum. The vast majority of modern day cars use an extremely sensitive mass airflow sensor which can be thrown off by these leaks. AMS offers a pre-dyno inspection for all vehicles being tuned, and it is highly suggested for most cars. Included in this inspection is a pressure test of the intake tract to be certain there are no leaks to hinder the your ECU calibration. This service is offered at $125 and can be performed prior to the car being tuned. Please be sure to inform your service representative as soon as possible if you intend to have this inspection performed before your dyno tune.

Mechanical Issues on the Dyno

As with any vehicle, you may experience mechanical issues during a dyno tune. These problems range from faulty injectors to improper installation of parts. If the tuner experiences any of these problems AMS will either attempt to correct them while the vehicle is still strapped to the dyno or the issue may be severe enough that the vehicle will need to be removed from the dyno altogether. In either scenario, the vehicle owner will be responsible for any labor necessary for repair, and in some cases may need to forfeit their deposit if the car is not able to be tuned during the scheduled appointment.

GTR Tuning

As true leaders in the field of GTR tuning we have been able to stay ahead of the competition at every horsepower level. Our never ending development has allowed us find fault in each system and work on solutions to correct them. We offer consistent and smooth driveability tailored to your specific uses for your GTR. We have worked to develop custom sensors for the GTR which solve complex problems with the original engine management. Through our continued development we were able to help COBB directly develop the speed density system for these cars, and still continue to work with them to tweak and improve the current system as the need arises.

Nissan UpRev Tuning

Since beginning to tune these cars we have noticed that in general not a lot of care has been taken by other tuners to do a full tune correctly. While others may only focus on full throttle tuning and still others simply do not have a firm grasp on tuning principles, we feel that we bring a lot to this market. We have been able to take cars that are already “tuned” and make an additional 15-30whp (forced induction). We pay special attention to things that others ignore so that we can maintain our principles of maintaining the best driveability, and most consistent results. No matter what your intended use for the car may be, we can also tailor your specific calibration to the cars intended use.

  • Experience with high HP N/A, turbo and supercharged applications
  • Able to tune the engine computer correctly for smooth automatic transmission operation
  • Number 1 in driveability, consistency and repeatability
  • Close relationship with industry giving us the ability to use the highest quality parts in conjunction with the correct software modifications
  • Custom tailored mapping to suit the drivers style, (road race/street/drag racing/linear power band)

Martin Musial's Philosophy of Tuning

Martin Musial has been involved with engine tuning for many years and has done thousands of cars ranging from street driven cars, road race competition cars, and over 1000hp drag cars. His approach to tuning emphasizes reliability while extracting the most out of engine performance.

"What many people don't realize is there is so much more to an engine tune than just WOT and peak horsepower. If the car is a dedicated drag car that might be ok, but for 99% of car owners it's not. Everything from driveability, cold start, fuel economy, and even idle quality make any car enjoyable and safe to drive. These areas of tuning are many times overlooked and are actually the most time consuming and difficult to perfect. WOT tuning can take a few hours, while driveability and running quality of the car can take a whole day sometimes. OEM engine calibrators literally have hundreds of hours in tuning the factory ECU so that it’s as perfect as it can be, this can not be replicated in one hour of dyno tuning no matter what anyone tells you.

I do my best to make sure a car will drive, start, idle the same if not better than a stock ECU. The only limiting factors of driveability sometimes involve engine management systems with limited functions and extreme engine modifications. A piggy back ECU controller or radical camshaft selection can prevent 'OEM like' driveability.

Another tuning aspect I'd like to discuss is reliable horsepower. I'd rather enjoy 400 horsepower for the life of my car rather than 440 horsepower for 10 passes, wouldn’t you? Since most of my customers run on pump gas, I carefully take into consideration the ability to make horsepower while minimizing detonation. Detonation will kill an engine, and the severity of it will determine when the fun will stop. It's a ticking time bomb and my goal is to diffuse it. My tuning process involves starting conservatively and then increasing power while carefully monitoring the knock sensor output and reading spark-plugs. I make sure that with my tune, the customer can throw almost any kind of abuse at the engine and it will survive."

Chris Black's Philosophy of Tuning

Chris Black has tuned everything from the world record holding AMS Drag and Time Attack cars to tuning countless other race and street cars. His attention to detail allows him to tune cars for the best driveability, longevity and horsepower available.

"There are so many cars being tuned at AMS from our various race cars, employee cars and customer’s cars the dyno is a very busy piece of equipment. Because of the wide range of systems and vehicles I am involved with I get a chance to learn something new about forced inducted cars almost every day. Every car is a challenge in some way. Tuning is a process which involves complex problem solving. There is never a cookie cutter solution that can be adequately applied to each and every car that comes through the door. Even cars with ordinary or basic modifications get tweaked, poked and prodded until I am absolutely certain that it is running at its highest potential.

Tuning isn’t a one man job either. Many times when there are problems with a vehicle on the dyno other AMS employees get involved to help solve the problem from our technicians to our engineers on staff. At AMS we will find any mechanical issues or driveability problems and fix them before the customer ever has a chance to notice them not just “tune around” the problem. The end result is a car that makes great power, has great driveability, runs the way it should and does so for a long time.

Because of the amount of knowledge we have between our 30+ person staff, I believe we have a leg up on any other tuning shop. With our extensive research, development and testing occurring every day not to mention the countless builds over the past 8 years have given us an immense amount of data and information which we use to solve almost any problem quickly and efficiently. In short, we know what works, how it works, and how to use it to our advantage. Our attention to detail and our drive to succeed gives the customer the best final product possible."
