Mechanical Issues

Valve Lash

Settings

OEM Honda

  • Intake: .007
  • Exhaust: .009

Aftermarket cams typically require different settings. Refer to the manufacturer for these specifications.

  • Make sure the engine has proper valve lash for the cams being used
Valve Adjustments
  • Adjust valves with the engine completely cool

Timing Belt

Installation

If it is too loose, you run the risk of skipping a tooth or running incorrect timing.

  • Needs to be installed properly
  • Should have minimal to no slack

Fuel

Amount
  • Roughly half a tank of gas is needed in the car for the tuning session

Clutch

Power Rating
Stock Clutch
  • If your build will make more setup than the stock clutch can handle the tuning session may need to be cut short due to clutch slippage.
Break-In

Oil

Type

Non synthetic oil should be used on all applications. We recommend Valvoline VR-1 on race cars. Any brand non-synthetic for street cars. OEM Honda filter or Puralator filter are recommended. We recommend non-synthetic oil because most built high performance engines are set at looser tolerances, and will consume synthetic oil much more frequently in comparison to non-synthetic.

  • All Motor: 10w30
  • Forced Induction: 10w30
  • Turbo Track Only Cars: 20w50

Summary

Paying close attention detail when addressing the points above will save money and time when at a tuning appointment. We can only fix certain issues on the day of an appointment depending on scheduling for that day. If you come to an appointment with a vehicle that is not working properly we may not be able to complete your appointment. If the problem is minor enough to be fixed at the shop during the day we can fix it. Our labor rates apply for time spent troubleshooting.

If after reading this you still don’t have the answer you are looking for, search or make a post about your issue on the forum and get some advice. If you still don’t get the answer you are looking for, send an email to [email protected].

Tuning appointments that are cut short due to cars not being properly prepped will result in loss of deposit, and fees will be assessed to cover time spent working on or tuning the car.
