Hello guys,
my car run´s at wot too lean since 2 weeks or so.
Yesterday i logged the data with my tweecer rt and i saw that my voltage
dropped the higher the engine rpm is.
At idle with lights on 13.6 v
at 1500 rpm 13.5 v
at 2000 rpm 13.2 v
at 3000 rpm 13.2 v
at 4000 rpm 13 v
at 4500 rpm 12.8 v
at 5000 rpm 12.6 v
at 5500 rpm 12.5 v
at 6000 rpm 12 v
The alternator is a new 3G 130 ampere, the battery is a new optima red top.
Before the 3G i run a 2G with 70 ampere. No problem with my old one.
I think that the voltage is not enough for my 255l/h fuel pump and the injector offset vs voltage is not set right.
Is my alternator shot
do you have any ideas ?
thanks
Markus
