Horsepower gains and driveability improvements can be made on the dyno by custom tuning computer chips and/or flash tuners such as the SCT XCalibrator 3, and by tuning fuel pressure and ignition timing. In addition to SCT tuning software, we have experience with Anderson PMS, Diablosport, HP Tuners, Accel DFI, FAST, and Pectel stand-alone fuel injection systems. In addition to horsepower and torque, our dyno can datalog Air/Fuel ratio, boost and vacuum. 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. 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 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.
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. Some cars are very simple to dial in, with straightforward combinations of parts, MAF sensors that are calibrated perfectly, fuel systems that are working right, etc. Those cars are done in about three 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 ( 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 really complicated 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. 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 of a Mustang is $85 for 3 runs with a printout of Horsepower, Torque, Boost (when applicable) and Air/Fuel ratio (tailpipe probe). A/F readings can be taken from the midpipe for an additional $30. All other vehicles are $100 to $150 depending on the vehicle. (Mustangs cost less because our datalogging equipment and dyno straps are already configured for them.) A basic dyno check ("Baseline dyno") does not include any tuning. For tuning rates see below: Dyno Tuning rates are as follows: Hardware required: 1989-1995 Mustangs require an SCT chip $299 installed (or $45 to remove & access the computer to use an SCT chip you supply). 1996-2004 Mustangs require EITHER an SCT XCalibrator-3 flash tuner $379, or an SCT chip $299 installed (or $45 to R&R the computer to use an SCT chip you supply). 2005-2012 Mustangs require an SCT XCalibrator-3 flash tuner $379. PACKAGE DEAL: Receive $75 off the price of a dyno tune when you purchase a tuner or chip and a custom dyno tune from us at the same time. Tuning Rates: Note: Dyno Tuning charges are in addition to the cost of the chip or flash tuner (if required) Basic "stock Mustang" Dyno Tune: For stock and mostly-stock Mustangs less than 5 years old with modifications limited to ONLY exhaust midpipes & mufflers (no long tube headers), pulleys, gears and "preferred" cold air intakes (Steeda, C&L, and BBK). Manual Transmission $225, Automatic Transmission $275 Bolt-On Naturally Aspirated Tune: For cars with typical bolt on performance parts such as throttles, air intakes, headers & exhaust work, cold air intakes, IMRC deletes, etc.(but still stock cylinder heads & cam[s].) Manual Transmission $300, Automatic Transmission $350 Note: Add $50 for aftermarket (non factory) Mass air meters and or any intakes with a 90 degree bend or change in tubing diameter within 6 inches in front of the MAF. Heavily Modified Naturally Aspirated Tune: For cars with ported or aftermarket cylinder heads and/or cam(s). Manual Transmission $400, Automatic Transmission $450 Supercharged Tune: With Factory Supercharger - $400 (GT500 & Cobra with stock heads, cams & stock supercharger ONLY (Does not include Supersnake, Saleen, etc.) Lightnings - $450 NON-Factory Superchargers - $500 with Manual transmission, Automatic $550 ADD $50 for tuning with water/methonal injection Turbocharged/Nitrous: Tunes will start at $500 but may go as high as $800 depending on vehicle. Nitrous Oxide tunes include a base tune for running without the nitrous as well as a nitrous tune. If we use a chip that you supply there is a $45 charge to remove & reinstall your computer and chip for tuning. For cars running leaded race fuel there is an additional charge of $10 per full throttle pull plus $30 for part throttle tuning. This covers 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 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, IF the MAF is calibrated correctly, and is in the FACTORY LOCATION, and 30lb 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. If you have another brand of chip we can not re-write it. You will have to purchase a new chip. If we use a chip that you supply there is a $45 charge to remove & reinstall your computer and chip for tuning. If you have a Diablo Predator we can make 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 the SCT XCalibrator-3. SCT no longer supports XCalibrator-1 software so we will be unable to tune your vehicle if you bring a Xcal 1 to us and will be required to upgrade to a Xcalibrator-3. 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 $125. There is a minimum charge of $125 for OBD-II (1996-present) and $175 for non OBD-II vehicles (1986-1995) to connect to the dyno for a retune. As a rule of thumb, if the Mass Air Flow sensor and fuel injectors were changed then most of the entire tune will be reworked on the dyno and charged accordingly. If the MAF sensor and injectors are untouched then the retune will be considerably less expensive than the original tune. Q. Is the dyno hard on the car? What are the risks involved? A. Running the car on they 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). |
