let me elaborate that
there are 2 PWM signals there,
1: is cooling PWM (IS TUNED TO THE mechanical mass of the injectors , so that the coils do not overheat, is tricky way, this cools the coils but does NOT EFFECT #2)
2: is fuel mix PWM (TBI is MAP baro sensor tuned, on hot engine + O2 sensor (lambda )fine tuned)
and then voltages.
all 3 need to be correct.
