Well, I did have JeepsRUs do this for me when I first had the pinging
problem. They (owner, Larie) put it on the DRB II (no charge) and saw no
errors at all. Then they retarded the timing by 6 degrees. Still have the
ping. This was the owner doing this too who I expect has far more
experience with jeeps, mpi and this problem than anyone else in the area.

It was after the DRB II timing adjustment that didn't work that they (Larie)
suggested the tornado thingy which also didn't work.

I'm going to call HESCO tomorrow and again Larie this week to see if
anything else can be done. Aside from any more voodoo (tornado thingy) or
with voodoo I'll welcome a fix. I'd rather not tear the engine apart again
but if I gots to do it I gots to do it.

I'm curious, why would the MPI Kit (the only change from carb) cause an
engine to be supsesible to ping? What is it about the fuel injection that
causes ping?

Also, I was told that the 4.0L head would clear the ping right up because of
the porting on the intake ports. If that's the case, it my problem a cause
of poor porting on the 4.2L head?

thanks,

bill

Then your computer works differently than the after market Ford and
GM work, in them we program, the initial advance and where we want the
total to be usually up around 38 degrees at two grand, probably for you
I'd wouldn't let it go full until three grand.
