If your ECU is silver-metal or gold colored it's ok. Typically an ECU-number ending in 9XX (977, 984, 962, etc). If your ECU is plastic (normally black plastic) you need a daughterboard to chip it. If you have a ECU-number that ends in 5XX (like 561) let me know because it's a different program. Altough I recommend that you upgrade to a 9XX ECU.

If you wish to have tracking on your order you need to select "With Tracking" when placing your order. The delivery time is the same regardless if the order is shipped with tracking or not.

I unfortunatley don't sell daughterboards. Try looking for one on sites like eBay

Best is 98 octane but 95 octane works as well!
