Datalog because of short voltage spikes at WOT

short voltage spikes at WOT?

so lately i've been getting very short voltage spikes when I hit WOT, usually at 90-100+ I finally got around to datalogging and it doesnt really show a big difference in voltage. I figured it be atleast a whole single volt off. Has anyone had this happen to them before? its confusing...

Are you talking about volts on your o2 or battery volts?
