What you receive
One original (stock) ECU file in binary .bin format, exactly as read from the control unit above: no modifications, no checksum changes. Files come from different reading sources, so size and memory layout can vary (full read or flash-only). The download link is emailed automatically within seconds after Stripe confirms payment.
Check compatibility first: compare every identifier above with your own read; a matching vehicle description alone does not guarantee compatibility.
