S14A UK spec ecu - car runs for about 5 seconds then dies

[motary]

I have a problem with a UK spec s14a ecu, which has type 4 nistune installed.
The problem is that the car runs for about five seconds then the power to the injectors is turned off at the ecu.
Could this be because of Nissan anti theft system V2? There aren't any fault codes when connecting it with a laptop and no strange readings either.
Thanks for help!

Sounds like NATS to me. S14A EDM models are definately NATS enabled

ECU will do just that it will cut injection pulsewidth off after about 3-5 seconds after initially running. But you should have flashing LED on the ECU indicating nats issue as well as NATS fault code 3 (are you seeing ECU OK inside Nistune latest 0.10.12 version?)

It is NATS system yep, we also had a problem with a faulty cas so it was causing problems, is there a way to get rid of nats without using the original items and syncing them to my ecu? I know of a version to use Nistune basemap with jdm eprom, but is that the only way?

Some ECUs can have the NATS EEPROM reprogrammed (eg K11) to remove it but I havent been successful with others

What is K11?

just found this on the website

P11 Primera SR20DE and later model K11 CG10DE/CG13DE ECUs have been added to the supported Type 4 board listings

K11 is Nissan Micra CG10/CG13

EEPROM is separate to Nistune. Is a small chip used to hold the NATS codes but it needs special reprogramming and not sure if all can be done. I'm wrestling with a P11 ECU at the moment trying to remove NATS from that for a customer
