This procedure has shown to help 24 valve ISB engines. It is basically
teaching the fly by wire accelerator on these trucks to reread the
position of the pedal and it's limits. Most complaints this will help
with is poor acceleration, improper shifting, bucking in 5 and 6
speeds. Has been known to increase fuel mileage in some instances.
Set parking brake
Disconnect negative battery cables on both batteries
Turn ignition key to run(to drain any remaining capacitors)
Let truck sit for 30 minutes( this is the recommended minimum)
Return ignition to OFF position
Reconnect both batteries and secure, not a timed event
Turn key to run position(not start) and depress accelerator
This simple plug-in
device allows you to get an additional 10% horsepower and torque from
your engine! Add it with injectors for a super combination! When
using the ADD with boxes that have a MAP Sensor provision, always plug
the ADD directly into the MAP Sensor, then plug the box harness to the
ADD. To explain it simply: The ADD has a microprocessor that acts as a
electronic voltage regulator, thus never allowing the engine computer
to see an over-boost signal.
My wise old mechanic who has worked on Mercedes for years told me that
if I put one gallon regular gas to a diesel tankfull after about every
four tanks that it would perform essentially the same job as a fuel
injector cleaner at a fraction of the cost.
