Guys I've hit a stumping block on the build the replacement ECU. Now I've had my ecu off and took note of all the numbers and letters off the back. I can find a few that match most of the numbers etc, but I can't find one that matches the circled below

The ones I can't match does it make a huge difference? I need the replacement ecu as I'm sending my original off for base map then fitting replacment to go down to carls. So who can shed some light on what I need to look for the correct ECU?! I do know its got to be off a astra but thats it.
Cheers
Edit : In Picture I say I can't match DLTW but I can match it....Its just the big long one under the barcode I can't match.
