4 Low Z (Peak and Hold) injectors (Full Sequential control)

----

Ignition outputs

with wasted spark coilpacks ...

* so 2 active coils or 2 passive coils ?

* In any case, 6 or 8 IGBT is good choice

** for 2 passive coils, even just 2 or 4 IGBT also enough (also enough for plenty active coils), but less spare power-outputs for extras

** HINT: even if you choose ECU with 6 IGBTs, make the harness so the 2 passive ignition coils are controlled by EC36/34 and EC36/36 (pretend that only 2 IGBT-s available while designing/making the harness)

*** this way even a "spare" VEMS ECU with only 2 power-IGBT ignout can control it. Although possible to do differently, there is no justification to wire in any other way.

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:

- “active flyback" is a must for low-Z injectors (universal: can be used for high-Z too)”.

* => does that mean 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

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)

Also, when you refer the project pages in the order comment (possuble multiple URLS, but max 1 project per page) we take another look when processing the order
