ok, I will try -100deg. Ive started from scratch more than a few times, the one time I could get the car to somewhat start and idle, the timing was way out (timing light). The engine wouldn’t run long enough to bring the timing in. After firmware update, it seems like timing was near 180 out; using 360 & -360 did nothing.

Few months late, but was this issue resolved? I’m having the same problem. Car runs on the installed ROM ECU, but I experience the same symptoms above when swapping to the NS15X.
