BMW S14B23 (M3 E30 2.3L euro version) turbo engine with (4 cylinders)
4 Low Z (Peak and Hold) injectors which I want to control them in Full Sequential Procedure
Ignition: with wasted spark coils pack which I want a wasted spark procedure
1 knock sensor already installed on the block
1 External map sensor connected in the Inlet Manifold
1 Exhaust Gaz Temperature already installed in the exhaust piping
1 Boost Solenoid connected to an external Wastegate
The Primary Trigger is: VR
The Secondary Trigger is: VR

Questions:
-For the : “active flyback" is a must for low-Z injectors (universal: can be used for high-Z too)”. Is that means that as now as I have mounted low Z injectors on this block and if I want later to go to High Z injectors this will be ok to control them with this ?
- YES, [active flyback] installed internally => suitable for either High-Z or Low-Z
-For the Ignition Driver : I have taken the 4+4 : 4 IGBT+4 Logic-level output, is it good ?
For 4 cylinder, either 4+4 or 6+2 is good choice (these can do 4 ignout, or wasted spark 2 ignout of course; either passive or active coils)
Trigger
Could please confirm my choice of the primary trigger : VR and the secondary trigger : VR ?
- measure primary and secondary trigger:
- if you find 2 pins with same resistance (usually between 350 and 1500 Ohm) in both directions, that is VR sensor. Otherwise HALL.
- take note of resistance (we'll confirm when we see your measurement)
