MD-250 Portable Series
At Moretto MotorsportZ we use the Mustang MD-250P Dynamometer. It is our dyno of choice because of the Eddy current brake. The MD-250 allows the vehicle be properly loaded as if it were driving down the road. By simulating the load properly, the tune will be very accurate to actual driving conditions.
The MD-250 specs are:
- 10.7" Rolls
- 2WD Low-Profile Performance Dynamometer
- Eddy Current Load Bearing Dynamometer
Our chassis dyno rates
- Dyno tuning - $175 per hour
- 3 dyno pulls - $175
If you search on Google “Dyno Tuning Checklist” you’ll see many lists and they all summarize the same points; be prepared, as it will save you time, money & our saftey.
Equipment & Needs:
- Make sure there is at least 1/2 tank of gas in the tank and use the brand/octane that you will be using most of the time. If you have low fuel we will charge you.
- If you vehicle has any hand held device (Diablo, SCT and so on) Please have it with the vehicle
- Make sure all fluids are topped up and NOT leaking; this includes engine oil, coolant, transmission fluid, differential/transfer case fluid, brake fluid, clutch hydraulic fluid, etc. There is a $100 Clean up fee if your vehicle pukes all over the dyno.
- Please make sure you are running a good brand of oil/filter. We also recommend making sure the oil weight is proper for your application. We HIGHLY recommend Joe Gibbs Racing Oil.
Wheels & Tires:
- Wheels should be balanced and properly torqued to spec.
- Tires should be in good condition. This means no belts/cords showing. No wheel studs allowed!
- Ensure your spark plugs are in good condition. Replace with new ones if necessary. Make sure your splugs are properly gapped. Most boosted applications we recommend a gap of 0.022-0.025
- If your vehicle is over 5 years old, it would be good to clean your engine grounds and grounding attachment points. A vehicles electrical signals need to be as clean as possible so the ECM has good signals coming in and going out. The engine harness should have no exposed wires.
- Battery/Alternator – Make sure these items are strong and operating properly. A weak battery can cause problems when reflashing the ECU
Vacuum lines, piping & seals:
- Make sure that your intake, vacuum lines, & intercooler piping are properly clamped so everything is sealed.
- Make sure your air cleaner is clean!
- You need to make sure you are tuning a healthy engine. One method of checking is through a Compression test. This will vary depending on the gauge being used. YOU SHOULD NOT have more than 20psi variance between cylinders. If you have one cylinder that is showing a greater variance than 20psi then you will need to repair that problem prior to your dyno tuning appointment. You can do this test before the tuning appointment or you can book some extra time before and I can do the test for you (at additional cost).
REMEMBER, our job is to develop a tuned calibration specific to your vehicle/combo, not fix everything that is wrong with it. If you show up with a car that is not in proper working order your appointment may have to be cancelled or rescheduled. If the problem is minor & can be fixed at our shop in a reasonable amount of time, we can fix it at $150 a hour. Please do not assume that it will be done for free.
