roadhazzard1 Posted August 7, 2017 Share Posted August 7, 2017 (edited) How does NATS work? engine conversion ecu/bcm matching? Hi all have now got the VQ25det in and turning over and priming fuel off the key although no spark. still using the original key and ignition Barrel and BCM not from the donor M35. We have these items from the donor car but do not have a matching BCM to go with the ECU from the donor car. How does bcm matching work in these cars? does key/ barrel and bcm all sync to tell ecu not to immobilise? assuming it needs the key to match barrel and then both these to match the BCM and ECU? Has anyone had to get a new bcm and had it programmed? If the new ecu from the donor car doesn't match the original bcm in the car i assume it wont let the car start. Is it possible to reset or reprogram the original BCM to match the new stock ecu from the car the motor is going into? The v35 bcm and m35 bcm have slightly different pinouts on the bcm so am hoping either there is a way to have the old bcm communicate with the new ecu. essentially can a locksmith make this work/ programming or some kind of NATS block? Short of going aftermarket ecu im out of ideas with this f**king car haha.

Duncan Posted August 7, 2017 Share Posted August 7, 2017 I doubt datascan can help but anyone with consult with the security option should be able to code keys like Bob said. Any nissan dealer or some specialist shops like Justjap.

Equilibrise Posted August 7, 2017 Share Posted August 7, 2017 I have engine and bcm from different cars. The only parts original are the ignition barrel and ecu. They didnt need to be programmed to work fine.
