Lipsylee Posted December 1, 2015 Share Posted December 1, 2015 Hello people , I just bought an ecm for my nissan 350z 2003 jdm and they sent me a slightly different one - the last four digits are different , will it work in my car ? Here is my ecu part number : PL. MEC31-570 E2 3205 Here's the part number they sent me : PL. MEC31-570 E2 2717 I just spoke to nissan dealer and they couldn't answer if it will work and can be recorded as they have never recoded a used ecu !!!! Thanks lee Quote Link to comment Share on other sites More sharing options...
Jetpilot Posted December 1, 2015 Share Posted December 1, 2015 I am led to believe it wont work as your key is coded to your ecu Quote Link to comment Share on other sites More sharing options...
Lipsylee Posted December 1, 2015 Author Share Posted December 1, 2015 Ok well that's the bit I was going to get nissan to do - recode the ecu to work with my key . So I just need to know if the ecu can work as the last four digits are different on the long part number Thanks lee Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted December 1, 2015 Share Posted December 1, 2015 Lee, the issue is the ROM loaded into the ECU. If you have a manual JDM the ROM number will need to be either CD405 or CD $15 only way to check this is to either get the Chassis number from car where ECU came from or we can read the ECU. I would need to read both ECU's though If the ECU is correct we can up load a Uprev licesen to turn the NATS off no problem. Quote Link to comment Share on other sites More sharing options...
Lipsylee Posted December 1, 2015 Author Share Posted December 1, 2015 Ok well mine is a auto , I can try and find the details for the one I just bought , Would it still be the same if I got the exact part number ecu ? I have to make a choice by the morning to either send it back for a refund and try and find the exact matching ecu or Keep it and hope it will be fine Thanks lee Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted December 1, 2015 Share Posted December 1, 2015 Only way to check ECU is correct is by reading ROM number we have found if you can't get a chassis/reg number. Quote Link to comment Share on other sites More sharing options...
