QUESTION

Can I use FORscan once tuned?

ANSWER

Yes. FORScan changes and custom tuning operate independently, so changes made in one generally do not affect the other.

FORScan modifications made before tuning will remain in place, and flashing a custom tune does not overwrite or undo those changes. Likewise, making FORScan changes after tuning does not require a re-tune.

In rare cases, FORScan may report an OSID mismatch when connecting to a tuned vehicle for the first time. If this occurs, please review the troubleshooting tips provided on this page.

After completing those steps, FORScan should connect normally whether the vehicle is running a stock calibration or a custom tune.

TIPS

1. Flash Back to the Stock Calibration Temporarily
This is the simplest and most reliable solution. Reinstall the stock calibration, restart FORScan, and create or save the vehicle profile. In most cases, this allows FORScan to identify the vehicle correctly and continue working even after the custom tune has been reapplied.

2. Check for Software Updates
Make sure you are running the latest version of FORScan. Older software versions may not recognize newer operating systems or calibration strategies.

3. Locate the Factory PCM Part Number
If prompted, the factory PCM part number can often be found directly on the PCM itself. In some cases, it may also be available through Ford As-Built Data records.
