Yeah, Iv been meaning to make a thread to cover the whole VZ V6 ECU changeovers and options available. As its getting ridiculous how often its occuring.
Right, the main three options are:
1) Brand new ECU (~$1100 for unit plus programming and fitting)
2) Second hand ECU only ($50-$100, MUST BE RESET OR IT IS USELESS! Also needs to be programmed to your cars engine calibration plus perform all relearns to ensure everything works without warnings)
3) ECU, BCM, PIM and key. Plug and play solution to fix the problem. (Price ranges from $250-650 depending on seller, programming ect)
Things to think about though..
Option 1 is most expensive, can cost more then quoted depending on Holden dealership, but the ECU is guaranteed not to be faulty. At almost quarter of the cost of alot of VZ's, its up to you whether you think its worth it.
Obviously, cheapest option is number 2... BUT I cant stress this enough, a second hand VZ V6 ECU is literally worthless without being security reset. The reset is what delinks the ECU from the BCM and PIM, it requires entering the security immo 4 digit key to delink it. Without this 4 digit key, the ECU cannot be security reset. And if its not security reset, it cant be linked to another vehicle!
Option three is plug and play. BUT the ECU and PIM need to be programmed for your vehicle otherwise you will receive ABS warnings, Engine warnings ect due to misconfiguration. In any situation this requires online subscription access to Holdens servers to flash in a valid calibration and a STRONG battery charger if performed in car otherwise flash will fail and ecu will be killed. If you can find a set from the exact same vehicle, then it will be plug and play.
Iv performed all three options on various clients cars so they do all work. Its more a matter of finding someone with experience with the VZ V6's otherwise you will be forking out 100's to someone that wont be able to do anything and waste your time.
Hope that helps!!
