For this im using PhatBobs beautifull Install User guide,
which is currently not covers how to wire up 5 COP's.
Because of the very high output of this turbocharged engine we will use 2 individual fuel line with 2 fuel pump,and of course 2 fuel pump relays.
Q: Can i run this two relay from the dedicated fuel pump relay output of the vems ECU,namely from the
EC36-pin15?
A: Yes, switching the both relays parallel is no problem at al an should work fine as long as the combined current from the relays does not exceed 250mA (unlikely)
This way
Injector wiring
The schematic below is NOT sufficient to individually switch off one of the injector sets.
Even if you remove a FUSE, the other fuse will supply BOTH sets of injectors (until it breaks, if too low currecnt).
if you insist to the schematic
- I recommend using one 15A or 20A fuse instead of 2 x 10A in parallel. (leave the other fuseholder empty)
- while the engine is off, remove the injector connectors from one set if you want to eliminate the given set.
- it's possible to install relays of multi-circuit switches but they bring more porblem than they solve!
Why don't you connect the 2 sets of injectors to independent injector outputs so you can switch them on/off through software ? That's the only good solution.
- obviously, you don't have enough (5+5=10) injector outputs to control every injector individually
- but max 2 lowZ or max 4 highZ (practically 3 in your case)
- 5 inj output for the primary set, and 2 outputs (2+3) for the secondary set
