If running S8 ( so over the L8 ) How are the extra injectors wired in ? are the just bridged off the started 4 ?

 

i would say but my loom was made for the 6 inj and normal p8 or s8 wiring just by the swapping of the plug on the extra 4 injectors

 

S.e.c.s s8 ecu connections (cosworth version)
=============================================


pin original ecu (l6,l8 and p8) s8 (if different)
-------------------------------------------------------------------------

1 power ground

2 lambda sensor input

3 crank sensor ground

4 crank sensor input

5 phase sensor ground

6 knock sensor ground user output 2 - after burner run

7 purge valve user output 1 - water injection

8 diagnostic socket injector 5

9 vref monitor user input 1 - user map switching

10 power relay

11 vref negative

12 general output warning lamp output

13 octane adjust injector 6

14 octane adjust injector 7

15 map sensor input

16 boost valve

17 throttle position

18 injector 4

19 power ground

20 positive supply

21 - tacho drive output

22 knock sensor input user input 2 - after burner

23 phase sensor input

24 ignition trigger ground

25 ignition trigger output ignition 1 (plugs 1+4) output

26 - ignition 2 (plugs 2+3) output

27 diagnostic socket injector 8

28 fuel pump relay

29 coolant sensor

30 vref positive

31 charge air sensor

32 injector 2

33 injector 3

34 idle speed valve

35 injector 1

 

So they run from the test and ignition ports, Interesting.

Thank you
