Hi wondering if anybody can help with this issue please.
My s14a is running stage2a with all the mods but not making power.
My 1st port of call was to swap back to the stock ecu and see if the power came back.
Instead the NATS system kicked in and the car won't start.
Pop the other ecu back in and it will start.
Not sure why the original ecu won't start the car.
I've tried disconnecting the NATS parts but then it won't start on either ECU.
Any suggestions on how to disable the NATS system completely?
Cheers
