The time we spend attempting to tune the vehicle is billable, regardless of the outcome. If we cannot complete the tuning session due to an issue with the vehicle, the time spent diagnosing, adjusting, and attempting to tune will still be charged.
Common Reasons a Vehicle Cannot Be Tuned:
- Faulty or non-functional sensors (e.g., AFR sensor, MAP sensor, knock sensor).
- Mechanical or electrical issues affecting engine performance.
- Boost leaks, fuel pressure problems, or misfires.
- Unstable ECU signals or communication errors.
Who is Responsible for Fixing Issues?
If we identify a fault that prevents tuning, it is your responsibility to fix it unless we have specifically agreed to carry out the repair work.
For example:
- If your AFR sensor is faulty and gives incorrect readings, you must replace it before tuning can continue.
- If additional work is required to resolve an issue, further tuning time will be chargeable.
How to Avoid This?
We highly recommend starting with an engine health check before tuning. This allows us to identify any major issues beforehand, reducing the risk of an unsuccessful tuning session and additional costs.
