ECU guides
Technical tuning guides by engine
ECU types, tools and tuning options for the engines workshops ask us about most. Every file is made for your exact read — check the calculator for power figures, or order directly in the file portal.
VAG 3.0 TDI (EA897 / EA897evo)
Audi A4/A5/A6/A7/A8/Q5/Q7/Q8, VW Touareg/Amarok/Crafter, Porsche Cayenne/Macan diesel
ECU
- Bosch EDC17CP44 / CP54
- Bosch MD1CP004
Typical gains
Stage 1: approx. +50–70 hp / +100–140 Nm (depending on version)
Tools & protocol
KESS3, Autotuner and FLEX — OBD on EDC17, bench/boot on most MD1
Available options
- Stage 1 and Stage 2 calibration
- High oil pressure modification on request with the Stage 1 file

The high oil pressure mod keeps the oil pump in high-pressure mode at low rpm, a common workshop request on EA897 engines.

ECU
- Continental SID212
- Continental SID212EVO

FAQ
Do you offer the high oil pressure mod on VAG 3.0 TDI?
Yes, on request. Mention it in the file portal when you order the Stage 1 file.
Can BMW B58 MG1 ECUs be tuned via OBD?
Older units can in some cases. Most newer MG1CS003/MG1CS201 units need a bench or boot unlock first.
Is Ford SID212EVO locked?
Many versions are. Send us the ECU ID and software number and we confirm the method before you start.
Which tool do I need for these ECUs?
KESS3, Autotuner and FLEX all work with our file service as slave tools. Which protocol you need depends on the ECU version.
