Questions
I'm preparing for assisting a startup attempt:
What is the preferred firmware for the VehicleFitment/Nissan 24-1 trigger ?
1.1.18 was tested, doesn't 1.0.73 work?
And if 1.1.18 is the one to go with, what vemsv3.ini should one use, does the one that comes with the 1.0.73 MegaTune package work ?

We have our first CA18DET running on the 24+1 trigger disk, with very goode results:
Power would have been higher and smoother if the 7psi actuator on the turbo (GT2871) had been stronger. We hope to get better pressure control with a 15psi actuator.
The owner reported back from his first track test that the engine was strong and responsive throughout the rev range.
We have used the standard wiring loom, COPs etc via the use of a harness adaptor:
