frank if i change it like for like second hand is my ecu unit going to accept the new engine someone else has said you have to marry them up do you know what he means by this I have the option of seeing a engine running and then buying it that way im confident of installing it without having to take it back, do the engines come out of the front on a trolley jack??????i cant recall anyone on here swapping one, i would do some crosschecks on nissan4u first
Thanks for the reply I take it the key, ring, from the barrel and ecu from the donor car of a second hand engine how difficult to remove the ring from the ignition barrel??? if i fit a re con engine would the ecu need re programming and would it have to be done by nissan i have a code reader can the ecu be re programmed with this??.You would need the key or chip from the key, the ring from around the ignition barrel and ecu, and unless you have access to a ramp the front will need to be removed to remove the engine, we usually drop them out the bottom at work, but if no ramp access that might not be easy.
How difficult, im not sure as I've never removed one from a k12 before, and ecu reprograming can be done by anyone with the correct equipment but your best Bet may be a dealer,Thanks for the reply I take it the key, ring, from the barrel and ecu from the donor car of a second hand engine how difficult to remove the ring from the ignition barrel??? if i fit a re con engine would the ecu need re programming and would it have to be done by nissan i have a code reader can the ecu be re programmed with this??.
Hi K12 fixer, I hope you may be able to help me, two questions re k12 1.2 2002I'd try just a straight swop, leaving your ECM to run the 1.4 engine, as for programing to engine if you leave batter disconnected which I would hope you would wilst changing engine all the self learns within the ECM should rest after long time disconnected from battery
One week ago,i swap a k12 1.2 and put the cr14. No need to change ecu. A just notice that the plug for the altenator is not the same. Just swap the altenatorIs it a straight forward swop 1.2 for a 1.4 engine????
