Juanra: Added engine code

<div style="float:right">__TOC__</div>

Siemens 5WY ECMs were used on both Delta and Beta motors on a range of vehicles from the mid 1990s to early 2010s. The main difference is the number of harness/socket and pin counts.

[[File:Siemens-5WY-5-Connector-Label.png|400px|thumb|right|2004 2.7L V6 Delta 4MBit]]The Siemens 5WY 5 connector ECM is found on an array of vehicles ranging between 1999 and 2012 equipped on the 2.5L and 2.7L Delta motors including the Sonata, Santa Fe, Tucson, Tiburon and Sportage. There are two types of EEPROMs used across this range known as 2MBit and 4MBit (or 256Kbytes and 512Kbytes). There are 7 major variants of this ECM. These variants can be identified by the 5WY designation under the SIEMENS logo here:

The vehicle chassis code, year, region and engine type can be found on the right of the label:

*N - North American (E = European)
*7 - Delta 2.7L (5 = Delta 2.5L)
*2 - 2002 year (3 = 2003, 4 = 2004, 5 = 2005, etc. etc.)
*G - GK model

There is a date code just above the barcode which identifies the date which it was flashed. The dates are written as "DAY.MONTH.YEAR" with the following examples:

*30.10.02 - October 30th 2002
*18.12.03 - December 18th 2003
