new feature Partial Write / Virtual Read / Calibration Only Read

[Roland@pcmtec]

2.10 has several new read and write methods which drastically improve read and write times. The following processors are now supported.

TC298 2018+ Ford Mustang, F150

TC1791 2015+ Ford Mustang, F150

TC277 2015+ Ford F150

Spanish Oak 1024k

Black Oak 1472k

The following processors have support coming soon.

TC1797 2015+ Ford Mustang, F150

TC1767 Ford Falcon Ecoboost, Focus, Mondeo

Write Methods

Partial Write:

Partial write is where we calculate the minimum number of segments required to write when writing a file to a vehicle. It is the fastest write method. This is the default when flashing a vehicle. If the TEC file has changed and we cannot calculated a diff we fall back to calibration only write.

Calibration Only Write:

When the editor can detect that a vehicle's operating system ID is the same as your file, it will automatically allow a calibration only write where the RTOS and code segments are not written. This saves time flashing vehicles where partial write is not available and only writes the segments containing the calibration values. This function is available in version 2.10 onwards.

Full Write:

When a partial write or calibration only write are not available we fall back to a full write. This is the slowest method and writes the same segments as recovery mode.

Recovery Mode:

Recovery mode is the same as a full write with less error handling to allow writing a PCM that is stuck in bootloader mode and will not respond to normal OBD commands.

Read Methods

Full Virtual Read:

When a vehicle has been detected as being 100% stock via matching checksums, operating system identifier, strategy and various other checksums we can virtually read the file from our stock database. We then only read critical information such as Serial, VIN and VID Block. This read method is effectively instant. This function is available in version 2.10 onwards.

Partial Virtual Read:

When a vehicle has been modified and we can detect the operating system ID and the operating system is detected as unmodified reliably (eg a non custom operating system) we allow partially virtually reading the file from our stock file database. Eg only the calibration, serial, VIN and VID block will be read. This is typically 4x faster than a full read. This function is available in version 2.10 onwards.

Full Read:

A full read reads all code and calibration segments.

Recovery Mode:

Recovery mode is the same as a full read with less error handling to allow writing a PCM that is stuck in bootloader mode and will not respond to normal OBD commands. This would typically only be done if you were attempting to get the VIN/VID block from a soft bricked PCM.

Read and write times:

The following read and write times have been calculated using a Tactrix Openport. Drewtech Mongoose is approximately 10% slower.
