Pre-Tune Checklist

Making sure your car is 100% ready for a Custom ECU tune is very important, as it will make the tuning process smooth, ensures your car will make the best power possible and makes certain that no time or money will be wasted. We are here to answer questions and make sure you prep your car properly, so ask us anything you may have questions about. If you rush the car, you will most likely have bad results and will probably have to fix stuff and come back for a retune, wasting time and money.

  • All tunes (Remote or In person) require a wideband. (I recommend the AEM UEGO (30-4110/30-4100) or the AEM X Series (30-0300). Do NOT get the AEM Failsafe gauge or the AEM Analog Wideband, as they are hard to log. BMW 335i, GTRs and 2015+ WRXs have a factory wideband, so there is NO need to add an aftermarket one.)
  • EVO 7/8/9 require an OMNI 4bar MAP sensor & an upgraded Boost Solenoid (for ECU boost Control).
  • EVO X require an upgraded Boost Solenoid (for ECU boost Control).
  • EVO 7/8/9 wanting Speed Density require an SD harness, an AIT sensor and an OMNI 4bar MAP sensor.
  • EVO 7/8/9 wanting Flex Fuel require an Innovate 3904 Ethanol Gauge and small EVO 8 or EVO 9 ECU pins
  • EVO X  wanting Flex Fuel require a Flex Fuel kit and the Tephra V3 ROM
  • SUBARUs should upgrade their Boost Solenoid, but it is not required.
  • Make sure your car has no oil/fluid leaks.
  • Do a boost leak test and make sure your car has no boost leaks. If you have questions about this, just ask me.
  • If your engine is older (ie 100k miles or more) or rebuilt, do a compression test to make sure the engine is healthy.
  • Make sure your car has no exhaust leaks. Check for exhaust soot where pieces of the exhaust system connect.
  • Make sure your downpipe is not hitting (rattling) the engine, transfer case or cross bars.
  • Make sure spark plugs are new & properly gapped. Here is plugs info for EVO's and Subaru's
  • Make sure all vacuum hose connections are zip tied/clamped.
  • Make sure all fluids are new and full.
  • Make sure the cooling system (Radiator & Fans) is full, bled and working properly.
  • Make sure the boost controller is installed correctly and the wastegate is preloaded properly. If you have questions about this, just ask me.
