5.5 Peak and Hold 8A/2A – 6/8
Siemens, MSD injectors - (two
injectors per channel)
Connection of 8 fuel injectors (Siemens,
MSD, Rochester) with a Peak and Hold
8A/2A. The same wiring example can be
used for fuel injectors with impedance
between 1 and 3 ohms and high impedance
fuel injectors.
In the example above, 4 fuel injectors are
controlled through Bank A and the other
4 are driven through Bank B. If necessary,
it is possible to join all 4 Peak and Hold
inputs to drive all the fuel injectors through
one injection bank.
In 6-cylinder engines, it is possible to leave
one Peak and Hold channel disconnected
or use that channel to drive supplementary
fuel injectors through Bank B.
5.6 Peak and Hold 8A/2A – 8/16
Bosch 160lb/h Injectors - (four
injectors per channel)
In the example above, a Peak and Hold
8A/2A and Bosch 160lb/h fuel injectors
are used. Fuel injectors with impedance
above 3 ohms (including high impedance
fuel injectors) may be connected in the
same manner.
O b s e r v e t h a t t w o c h a n n e l s a r e
disconnected, but, if necessary, these
channels can be used with an additional
4 fuel injectors connected to each one
of them, controlled through any injection
bank.
