1. Injection timing advance +120 from base map.(ex.280 -> 400) ...The firing order is 153624. But the Injection group is 1&4,3&5,2&6 2. V1.4 and earlier will have two of the idle stepper motor wires the wrong way around, swap Aux 6 and Aux 7 pins around to make it work correctly.

Thank you for your advice! I tried it and my rough idle was little fixed. (Misfire was completely fixed!) Unfortunately, I found that JZX90 plug in ECU have another hardware issue... JZX90 plug in ECUs ISC Stepper port AUX6 and AUX7 are reversed. Therefore, ISC does not work at all in its original wiring. When I tried swapping the AUX6 and AUX7 connector pins, ISC worked properly and rough idle was almost fixed. ...What does "Plug in" means?

I'm Japanese. So my english is very poor sorry! My JZX90 (1JZ-non vvt) have 3 group Injectors. The combination is below. 1st: 1-4, 2nd: 3-5, 3rd: 2-6 firing order 1 5 3 6 2 4. Default Injection Mode is Semi-Sequential Injection on my JZX90 plug and play ecu. But the help text says... ·6 Cylinder, firing order 1 5 3 6 2 4. Works nicely as per rule. Fuel sits in port for 120 degrees longer on the higher numbered cylinder in the pair than the other. ·Injector drive 1 is wired to injectors for cylinders 1 and 5. ·Injector drive 2 is wired to injectors for cylinders 2 and 4. ·Injector drive 3 is wired to injectors for cylinders 3 and 6. Does Semi-Sequential Injection really work on JZX90? Unfortunately, My JZX90 have rough idle...
