Questions
Are these files modified?
No. Every file is an original (stock) read of a Fiat Siena control unit, delivered exactly as read. If you need a modified file, order tuning below.
How do I find the right file?
Read the ECU with your tool and compare the hardware (HW) and software (SW) numbers — and the calibration when several files share one software number. The vehicle name alone is not enough: the identifiers decide.
How do I get the file?
Create an account on our file service, top up your balance and download the file straight away. Every original file costs €20.
My number is not listed. What now?
Send us the HW/SW numbers of your ECU on WhatsApp or by email. We check our full archive and reply.
Can you tune Fiat Siena?
Yes. We make Stage 1/2 files and DPF, EGR, AdBlue/SCR and DTC solutions for Fiat Siena (depending on the engine). Upload your read on our file service.
