About remapping
The SEAT Leon accounts for 1,562 files in our catalogue, with a genuinely balanced spread between the TDI diesel range and the TSI and TFSI petrol turbos. It shares its mechanical basis with the Golf and A3, but tends to attract owners with a more performance-oriented outlook.
Stage 1 makes up 1,314 files, with 182 Stage 2 — one of the higher proportions among mainstream hatchbacks — and 104 speed limiter removals. The ECUs include EDC17C64, EDC17C74 and PCR2.1 on the diesels, and MED17.5.21, MED17.5.25 and MED9.1 on the petrols.

Why does the Leon attract more Stage 2 work?
It tends to appeal to owners with a more performance-oriented outlook, so a higher proportion arrive with intake or exhaust modifications already fitted.
Does it share files with the Golf?
They share mechanical architecture and ECU families, which broadens our coverage, but files are matched to the specific ECU reference of each car.
What is Stage 2?
It assumes mechanical modifications beyond the software. If your car is standard, Stage 1 is what applies to you.
