Stage 1 EGR OFF tuning file for HW AV61-12B684-GA SW BV61-12A650-AXL SW Upgrade BV61-14C204-AXM FORD FOCUS Mk3 1-6L 8V TDCI 70kW-94HP SID807

ECU Hardware Number: AV61-12B684-GA

Software Number: BV61-12A650-AXL

Software Upgrade Number: BV61-14C204-AXM

ECU Type: Siemens SID807



HW SW SW Upgrade must match in the same order for Ford – you can use the SW scanner tool on our website. If this number matches the file should be a 100 percent match. Simple tip – HW number always contains 12B684 – SW always contains 12A650 – SW Upgrade always contains 14C204 – Even if your tool identifies these in the wrong order you can match the correct file by following this logic.

IMPORTANT: The file portal is designed for professional users with genuine tuning tools. We do not offer support to users with clone tools because they cause lots of problems.

0. Stage 1 on the 1.6 75 95 100 115 8v TDCI Engines with the Siemens SID807 ECU all remap to the same power because they use the same turbo and injectors – A Stage 1 Remap gives a typical result of 145 to 150 BHP with 330 to 350Nm depending on the vehicle condition and the dyno used.

1. We assume that only professional users will use the file portal and as such should have the knowledge to check the integrity of a tuning file before uploading it to the ECU. If you don’t know how to check the file matches your original read – then you will be proceeding at your own risk.

2. Each folder has an original file ORI – a modified MOD file without the checksums calculated labelled as NO_CKS – and a MOD file with checksums calculated labelled as CKS_CALC.
-If you have professional paid tuning tools – then you should allow your tool to fix the checksums.
-We included the full original file because most tools need this to calculate or patch the RSA checksum.
-We also included a file with CKS calculated and RSA sum patched.
-Clone users – You must use the file with CKS repaired. (We don’t condone the use of clone tools – and we can’t stop you from using clone tools and we can’t stop you from buying the file – but we made the files with checksum corrections so that you don’t need to message us to ask us to fix the checksum).

3. Users with Auto tuner tool or those using a full read of SID807 with TC1796 processor: your tool will sometimes use a 2MB file instead of a 4MB file or a 4MB file when the file we supply is 2MB. We made a tool which transfers changes absolute in to your original file. SID807EVO uses TC1797 processor and should have a 4MB file however some tools will still produce a 2MB file and write only the data block.

4. Users with CDM flash tool
-You can use the same transfer changes utility – the file is almost the same – you must reset the values outside of the datablock to match the original file in WinOLS.

5. If programming over OBD with a Virtual read (VR) file – ensure that all 3 HW – SW – SW Upgrade match exactly and that the file size is the same as your tool expects. The files here are the same format as Dimsport OBD tools expect. If using clone tools approach with extreme caution when using virtual files because you wont have a backup – proceed at your own risk.

6. If the file you purchased has EGR delete – it is strictly for off road use – track use – diagnostic purposes only. Please do not use the delete files for road use.

Instructions for EGR delete:
-EGR is set to hold closed via hysteresis maps. Associated faults are removed.
-EGR can also be unplugged if faulty – it’s a big solenoid below the air box.
