PRE-TUNED ECM NOTES:
ECMs are pre-owned in A1 condition (LMM are NEW Bosch ECMs)
Since this ECM did not originally come out of your truck you will need to perform a 30 minute Pass-Key Security Relearn Produre which is standard with GM vehicles.
You install the Pre-Tuned DURAMILEAGE ECM and then swap out your truck's ECM when you have to visit the Dealership.
2006-2008 LBZ/LMM ECM's may(not always) need to have a Fuel Injector Flow Rate Programming performed by a Dealership IF after installation the truck has a non-resetable Check Engine Light caused by the injector flow rates not matching the flow rates stored in the glow plug module. This is a quick and simple 15 minute procedure which can be performed by any shop with a GM Tech-2 diagnostics tool.
PRE-TUNED ECMS MAY TAKE 1-3 WEEKS TO SHIP DEPENDING UPON AVAILABILITY OF CORES BEING IN-STOCK.
