alternator output during high loads
alternator output during high loads
(OP)
I have been noticing that on some fuel injected vehicles the voltage drops to battery voltage 12.x-12.6 volts during wot operation. Does the pcm stop fielding the regulator during wot? Maybe you know something I don't?

cos the computer has got some ..built in.. compensation tables.
and on the one i got, compensates down to 7 volts !!,
the lower the voltage, then the longer it takes the ..injectors.. to open.
so when the volts are low, the computer will open the injectors earlier, to compensate
on the one i use , you can have a ..defult .. setting,
or a programmed setting, according to the injectors workings/duty cycle
and will also alter the ignition as well
hope this gives you some info
