Anyone tried external peak and hold drivers?

Recommended Posts

PLEASE do not get the Always Electrical Malfunction. I've had two of these and they both failed within a short period of time. I fought for a refund instead of a second replacement because I didn't want that POS on my car.


FJO makes a good product, and if your soldering skills are good, the version 2.0 peak and hold injector divers from jb performance jbperf injector driver have worked well for me.

Sweet.......exactly the type of information I need.


I'm going to experiment with this on a 2002 nissan frontier supercharged ecu but I figured the MS guys are on the sharp end of external peak and hold drivers.


One thing I want to do is check any tuning differences between running dropping resistors and external peak and hold drivers on the same car under the same conditions.
