Pre-tune Checklist


   Before beginning your tune, it is very important (on any vehicle) to verify that your engine is mechanically ready. Attempting to tune a vehicle with even a minor boost leak, will not only put your engine at risk, but can greatly increase the amount of time the tune process can take. It is highly recommended that you go through the below checklist, to make sure your car is 100% ready to make power.

 

  • Change oil/check oil level

  • Clean mass airflow sensor (Mazda specific)

  • Clean air filter

  • Replace spark plugs (if over 20,000 miles on current plugs)

  • Gap spark plugs to .028

  • Check for any loose clamps/couplers

  • Shake intake/intercooler pipes to check for noise (as this can cause false knock)

  • Check tire pressure

  • Check brakes for proper operation



**It is very important that your vehicle is in 100% mechanical operation condition, before adding a custom calibration to you vehicle. If you have running/drivability issues, or any check engine lights on, please contact us for assistance. However, if you have added a larger intake or turbocharger, and need a base file to start your vehicle, that is a different case, and we look forward to working with you!**






Datalogging How-to (Ford)



     Only WOT datalogs need to be performed on Ford vehicles. Due to the Speed Density based ECU logic, the ECU has the ability to automatically adjust for a variety of intakes and intercoolers on the market.


   WOT logs should be performed in 4th gear, after the vehicle is fully warmed up. Drive the car in 4th gear at around 2,500 RPM, and press the center button to begin recording. Press the accelerator pedal all the way to the floor and rev the engine up to 6,500 RPM. You can then let off and end the log by pressing the center button. It is very important that you start your WOT pull at 2,500 RPM and end your pull at 6,500 RPM.


​As always, be safe and courteous to those around you. Try to avoid any traffic, if possible​. I also want to mention, the flatter and straighter the road these logs are performed on, can greatly improve the results of your custom tune. Consistency is very important during the e-tune process.







Datalogging How-to (Mazda)

 

     There are 3 different types of datalogs that will need to be performed during the tuning process. The first 2 are idle and maf calibration datalogs, and then we move to wide open throttle (or WOT) datalogs. The idle and maf calibration datalogs are done to dial in your mass airflow sensor calibration to your particular intake and fine tune your Air/Fuel Ratio (AFR) to meet commanded targets. Once those are dialed in, WOT logs will be performed to maximize performance. Please log all the "default" parameters on your Accessport.

   The idle log should be performed after the vehicle has AT LEAST 100 miles of city driving. Warm the vehicle up to normal operating temperature (~180*), and make sure the heat/ac are turned off. Press the center button on the AP to start logging. Wait 10 seconds and press the center button again to stop logging.

   The maf cal log should also be performed after the vehicle has AT LEAST 100 miles of city driving. Warm the vehicle up to normal operating temperature (~180*), and make sure the heat/ac are turned off. Drive the car in second gear and let off the throttle until the car is almost to a complete stop. Press the center button on the AP and very slowly press the accelerator pedal increasing RPM’s up to 6,000. Do this very slowly and do not build any boost during this datalog. Once you reach 6,000 RPM, you can let off and press the center button to end the datalog.

   WOT logs should be performed in 4th gear, after the vehicle is fully warmed up. Drive the car in 4th gear at around 2,500 RPM, and press the center button to begin recording. Press the accelerator pedal all the way to the floor and rev the engine up to 6,500 RPM. You can then let off and end the log by pressing the center button. It is very important that you start your WOT pull at 2,500 RPM and end your pull at 6,500 RPM.
