|Dyno testing and tuning is available on our state-of the art Mustang MD1100-SE Dyno. The Mustang dyno incorporates an eddy current load controller to simulate the actual load (combined aerodynamic drag, rolling friction, and vehicle inertia [weight]) the vehicle experiences while driving on the street or racetrack. This allows for more accurate tuning under conditions that match the real world. These conditions can’t be simulated by an inertia-only dyno (like the more common and less expensive Dynojet). Our dyno can also hold a constant speed while engine load is varied from idle all the way up to full throttle. This allows proper mapping of certain tuning parameters that is just not possible on other shop's dynos. These are just a few of the reasons why a Realspeed tune is the best! Realspeed is Long Island's first tuner certified with SCT's advanced "Calibrator" status.|
Horsepower gains and drivability improvements can be made on the dyno by custom tuning computer chips and/or flash tuners such as the SCT XCal 4, and by tuning fuel pressure and ignition timing. In addition to SCT tuning software, we have experience with Binary Editor, HP Tuners, Anderson PMS, Diablosport, Accel DFI, FAST, and Pectel and other stand-alone fuel injection systems.
Our dyno can datalog Air/Fuel ratio, fuel pressure, boost and vacuum, in addition to horsepower and torque. OBD II vehicles are datalogged with SCT Live Link or HP Tuners software. EEC-IV vehicles (86-95 Mustang) can also be datalogged using our exclusive in-line signal scanner and/or EEC emulator software.
FREQUENTLY ASKED QUESTIONS ABOUT THE DYNO
Q. How do I get my car dynoed?
A. Call 631-563-7325
to make an appointment.
Q. Why should I dyno tune my vehicle?
A. You’ve invested in your vehicle's performance. Finish the job right by making sure the engine reaches its full potential. No matter how good the tuner, you can’t get live real-time feedback and customized adjustments with a mail order tune. Every car has subtle differences. When you want the best possible performance there is no substitute for an experienced tuner working in the same room as the engine and making adjustments specific to your individual car.
At Realspeed we treat every vehicle with the care and dedication that we would want for our own car. We have extensive knowledge of Ford electronic engine controls, SCT, HP tuners and Binary Editor tuning software, high performance engine design theory and forced induction (supercharging, turbocharging, nitrous). We have the experience to give you the best tune possible. We go the extra mile to make sure your tune comes out right (see below).
Q. What makes a Realspeed tune better?
A. TIME and EXPERIENCE make a Realspeed tune the best. We simply put more time into tuning each vehicle than other tuners do, and we have more experience getting down to all the little details that make the engine run better. A Realspeed tune is much more than a quick “tweak” of your car. We thoroughly go over your car and your computer’s calibration and take the time to do the extra steps required for the best possible result.
- Full throttle, part throttle, idle, transient fuel (tip-in) and cold-start parameters are tuned
- Realspeed does a complete 38 point MAF Transfer calibration mapping, not just full throttle like some other tuners
- SCT tuning software Certified Tuner. Certified at their highest “Calibrator” level through SCT’s Advanced Dealer Training Program. Recurring training keeps us up to date with the latest advancements in engine controls and tuning software.
- Wideband Air/Fuel (A/F) Ratio gauge inserted in the midpipe, not the tailpipe, for more accurate A/F readings
- Our Wideband Air/Fuel sensor is calibrated before each tune
- We use a more accurate and more expensive NTK wideband A/F sensor for tuning instead of cheaper and less durable Bosch sensors
- Realspeed’s Mustang Dyno simulates full vehicle weight AND aerodynamic drag for more accurate “real world” tuning than other dynos. Unlike many competitor’s cheaper dynos, our Mustang MD1100-SE dyno also allows us to hold the engine rpm steady even as the throttle angle and power is increased. This enables us to do more advanced engine calibration work that can’t be done with many other dynos.
- Fuel pressure is checked and/or set, timing is checked/set, spark plug checked for the correct type & heat range, O2 sensor function checked, ACT & coolant temp sensor function checked, TPS sensor checked
- 1986-1995 Mustang sensor functions and computer outputs are data-logged with our exclusive hardware and software to read computer data that many other shops can’t get
- 1996-2017 Mustangs are data-logged with SCT Live-Link & other software to see & record computer inputs & outputs in real time
- Tuned until the car is right, with no pre-set time limit or “rush-jobs”
- Vortech Superchargers Top-Tier Installer. Recommended by Vortech for tuning their superchargers. Experienced with Roush, Whipple, Kenne-Bell, Paxton, Procharger, Powerdyne, Saleen, VMP, Magnuson, and Edelbrock superchargers. Experienced with Hellion, HP, On3 and other turbocharger systems.
Q. How long does it take to tune a car on the dyno? How many passes do you make?
A. The short answer is “As long as it takes."
Regardless of the combination, we tune the car until it is right. There is no pre-set limit on how many pulls we will do. Ford had a team of engineers working on the engine calibration for your car for months (sometimes years) before they released the vehicle for production. If you’ve changed multiple components related to engine calibration, why would you settle for someone who tells you they can properly re-calibrate the car in just an hour or two? Good calibration work takes time.
Some cars are very simple to dial in, with a straightforward combination of parts and everything is working right. Those cars are done in about four hours with as little as three or four full-throttle pulls and a few "miles" of part throttle tuning on the dyno. Other cars have more complicated setups (variable cam timing, electronic “drive-by-wire” throttle control, computer controlled electronic fuel pressure control feedback systems, MAF transfer functions and transient fuel tables that need a lot of work, injectors or meters that are past capacity, fuel pressure that needs to be adjusted, supercharger belts that are slipping, spark plugs that need to be re-gapped, etc.) A complicated or “uncooperative” car could take all day and 15 or more passes.
If you are waiting with the car while we tune it, be prepared to wait for at least 6 hours, minimum. A waiting room with a couch, table and TV is available for your comfort, but the best thing to do is to arrange to drop the car off for the day. We take our time and will give you the best results possible if we are not rushed. Typically we spend an hour or more looking over your car and writing a fully customized tune before we even make the first dyno pull.
Q. How much does it cost to dyno my Mustang?
A. A basic dyno check with 3 runs and a printout of Horsepower, Torque, Boost (when applicable) and Air/Fuel ratio (tailpipe probe) is $90. Air/Fuel readings can be taken from the midpipe for an additional $30 on most vehicles.
A combined Dyno test, data-logging and consulting session to evaluate the current tune on you vehicle is $140.
A basic dyno check or consulting session ("Baseline dyno") does not include any tuning. For tuning rates see below:
Note: All prices above and below are for a MUSTANG. For all other vehicles call 631-563-7325. (Mustangs cost less because our equipment is already configured for them.)
Dyno Tuning rates for Ford Mustangs are as follows:
1989-1995 Mustangs require an SCT or Moates chip and software liscence: $349 ($199 for chip + $150 software license=$349).
1989-1995 Mustangs must have a dedicated fitting installed for our wideband AFR sensor. If you don’t have one we will weld one in for an additional fee before tuning.
1996-2004 Mustangs require EITHER an SCT X4 flash tuner $399, or an SCT chip: $299.
2005-2017 Mustangs require an SCT X4 flash tuner: $399.
Note: Dyno Tuning charges are in addition to the cost of the chip or flash tuner.
There is an additional $35 charge to access the computer for ALL computer chip tunes and re-tunes. You can avoid this fee by selecting an Xcal flash tuner instead of a chip on 1996 and newer vehicles.
PACKAGE DEAL: Ask for $50 off your tuner or chip when you get a dyno tune from us at the same time.
Stock or standard Bolt-On Naturally Aspirated Tune:
For Mustangs that are stock or with modifications such as exhaust midpipes or headers, mufflers, pulleys, gears and name-brand cold air intakes (Steeda, JLT, BBK, Roush, Airaid, KNN), IMRC deletes, etc.(but still stock cylinder heads & cam[s].) This includes name-brand mass-produced intake manifolds (Ford Racing, Edelbrock). This category also includes mechanical throttles (2004 and older) but not electronic throttles.
Manual Transmission $400, Automatic Transmission $450
Note: ADD $50 EACH for aftermarket (non-Ford) fuel injectors and/or aftermarket mass air meter (MAF). A factory MAF electronic sensor that has been relocated into a custom piece of tubing is considered a non-factory MAF because the calibration is changed by the new tubing shape. Aftermarket air intakes with a 90 degree bend or change in tubing diameter within 6 inches in front of the MAF may also be charged as an aftermarket MAF because of the turbulence they create over the MAF sensor.
Heavily Modified Naturally Aspirated Tune: For cars with ported or aftermarket cylinder heads and/or cam(s), non-original electronic throttles on 2005 and newer cars (drive-by wire) or cars with BOTH non-factory fuel injectors and non-factory mass air meter (MAF). A factory MAF electronic sensor that has been relocated into a new piece of tubing is considered a non-factory MAF because the calibration is changed by the new tubing shape.
Manual Transmission $500, Automatic Transmission $550
With Factory Supercharger - $450 (GT500 & Cobra with stock heads, stock cams & stock supercharger ONLY (Does not include Supersnake, Saleen, etc.) (Lightning trucks - $550)Upgraded pulleys are OK, but cars with aftermarket injectors and MAFs will be charged at the “Non-Factory” Supercharger rate.
With NON-Factory Superchargers:
Manual Transmission $600, Automatic $650
ADD $50 for non-factory camshaft(s) in combination with a supercharger
ADD $150 for tuning with water/methanol injection
Turbocharged or Nitrous: Tunes will start at $600 but may go as high as $950 depending on vehicle. Nitrous Oxide tunes include a base tune for running without the nitrous as well as a nitrous tune.
For cars running leaded race fuel there is an additional charge of $50. This goes towards the cost of replacing the sensor on our wideband Air/Fuel ratio gauge, which is harmed by leaded fuel.
Dyno rates may vary for special applications, such as racecars requiring custom work, other brand vehicles, different tuning software, etc. Dyno rates above are for tunes based on a Ford computer. Stand-alone computer systems are priced differently. Call for info.
Dyno tuning prices listed here may include standard tuning procedures (as required) such as setting timing, adjusting fuel pressure, tightening supercharger belts, and checking 1 spark plug to make sure the correct type and heat range is installed. These prices DO NOT include mechanical repairs such as changing clogged fuel filters, changing or re-gapping spark plugs, fixing supercharger belt alignment problems, or repairing other pre-existing mechanical issues. WE HIGHLY RECOMMEND BRINGING YOUR CAR TO US TO LOOK OVER BEFORE YOUR DYNO APPOINTMENT, TO AVOID TIME CONSUMING AND EXPENSIVE DELAYS ON THE DYNO. FRESH SPARK PLUGS OF THE TYPE AND GAP WE RECOMMEND, AND A FRESH FUEL FILTER SHOULD BE CONSIDERED A “MUST“ FOR ANY HEAVILY MODIFIED OR SUPERCHARGED CAR.
Important notes about tuning cars with Nitrous Oxide:
We will only tune cars that have functioning pressure gauge and bottle warmer. Knowing and controlling your nitrous pressure is crucial to good performance with nitrous oxide. We simply will not send a car out the door with our name on the tune while guessing about the bottle pressure it was tuned with.
You must bring the car to be tuned with a FULL nitrous bottle, or inform us at least 24 hours before your tuning appointment if you need your bottle filled. If the bottle runs low during tuning we cannot continue the tune until the bottle is refilled. This ties up scarce dyno time. If we have to refill your bottle to finish your tune you will be charged for the bottle re-fill and the time it takes to un-strap and then reconnect your car to the dyno, so that we can dyno other cars while your bottle is sent out to be filled.
Q. Do I have to buy a chip (or tuner) for dyno tuning?
A. 86-93 Mustangs can sometimes be tuned fairly well with just an "Mechanical tune" using an adjustable fuel pressure regulator and a timing light, but only if the MAF is calibrated correctly, and is in the FACTORY LOCATION, and 24lb/hr or smaller fuel injectors are being used. ALL OTHER MUSTANGS require a chip or flash tuner to make proper tuning changes. ALL MUSTANGS WITH COLD AIR INTAKES WITH A BEND IN THE TUBING IN FRONT OF THE AIR METER WILL HAVE A MUCH BETTER TUNE RESULT IF A FULL COMPUTER TUNE IS DONE.
Q. I already have a chip (or Flash Tuner). Do I have to by a new one?
A. It depends on what brand you have. We can re-write SCT brand chips and XCalibrator or Live-Wire Flash tuners. We can also re-burn Moates chips for 1995 and older vehicles. If you have another brand of chip we cannot re-write it. You will have to purchase a new chip. A $150 software license fee is included in the price of the chips we sell. If you supply your own chip you will still be required to pay $150 for the software license.
There is a $35 charge to remove & reinstall your computer and for chip access when tuning with a chip.
If you have a Diablo Predator we can make basic adjustments to the Wide Open Throttle (WOT) fuel and timing using the on-screen adjustment in the handheld unit. More involved tuning will require a switch to an SCT tuner. SCT no longer supports XCalibrator-1 software so we will be unable to tune your vehicle with it. You will be required to upgrade to an Xcal-4. If you bring us an XCalibrator tuner that is more than 3 years old you may be charged a small fee for the time it takes us to upgrade it to the latest firmware.
Q. If I modify my car after it is tuned, what does it cost to re-tune it?
A. Minor changes such as recalibrating the speedometer to match a rear-gear change are often done at no-charge as a courtesy to our customers. Prices for more extensive retunes which require dyno-time vary depending on how extensive the changes are to the vehicle. The price for a re-tune could be as much as the original tune or as little as $200. There is a minimum charge of $200 to connect to the dyno for a retune. Cars tuned with a chip will also be charged a minor fee to access the computer and chip. As a rule of thumb, if the Mass Air Flow sensor and fuel injectors, and/or electronic throttle or camshaft(s) were changed, then much of the entire tune will be reworked on the dyno and charged accordingly. If the MAF sensor, injectors, cam(s) and electronic throttle are unchanged then the retune will be less expensive than the original tune.
Q. Is the dyno hard on the car? What are the risks involved?
A. Running the car on the dyno puts no more load on the engine than going full throttle on the street (or track). In many ways running a car on the dyno is actually safer than running your car full throttle on the street (or track), because conditions such as air/fuel ratio, coolant temperature and ignition timing are monitored closely.
Any time an engine is operated at full throttle, whether on the street, racetrack or on the dyno, there is a small risk of something going wrong or a component failing. While this risk is actually somewhat smaller in the closely monitored environment of a dyno session, the risk still exists none-the-less. Realspeed Automotive, its employees and owners assume no liability for engine or driveline damage that may occur while the vehicle is operated on the dyno. All dyno work is strictly and expressly AT THE CUSTOMERS'S OWN RISK. All dyno services require a signed liability release form. Customers are still responsible for dyno charges if the vehicle breaks on the dyno (prorated based upon time on the dyno).
