Quoting from Intense-dakota.com:
Tips & Tricks - How to adjust ignition timing-
Question: Can I adjust my ignition timing?
Simple answer....NO.
"Some people have modified their crank sensors to allow minor timing adjustments...this is NOT an easy modification and requires a scanner to get the timing set properly. We do NOT recommend this at all."
Now if it was up to me, and it is, I would take heed to this warning and not try it again. Yes, I DID do it under the recommendations from members on this board until I found this article stating not to do it. I quickly reversed what I had done and put things back to stock location. In all fairness, I didn't see any gains from this modification and I do not know if it did any damage either.
Post your thoughts.

I would say that it is entirely up to you on whether you believe this single site or all the others that suggest the mod.
After reading the comment I would say that they have ignition timing confused with injections timing. I don't have any idea what a "scanner" would have to do with ignition timing.
It also says that "this is NOT an easy modification." Do you also agree with that statement? If you found the mod very difficult to do then you might want to heed the article. You should also note that many or all of the tips on that site were plagerized from another site and NOT based on their own experience.
I'm also sure that you can find an article that suggests that a factory engine never be modified from the original specs.

You are right about it NOT being a hard mod to do, I found it quite easy, I was quoting it as they said it. I am wondering why they would need a scanner also. I posted the article to draw attention to it and find out if in fact it would harm the engine to do it. I was a little worried about leaving the crank sensor out of its original position after reading the article. I need some good, sound info on this to prove if it does work and if there needs to be other adjustments made in conjunction with it. How does it REALLY affect the timing? Has anyone "scanned" their dakota after doing the mod or are we all just using our "butt dyno" and thinking it made a difference.

i think it's quite simply (horse sh*t)
how many of us have the crank sensor mod done?
any how many of us have had a problem from it?
(i sure haven't)
i'd like to hear Larry chime in on this one
all that money the guy has in that stroker
i sure dont think if it was a danger to the motor
he'd have the mod
bludak
"it's like 6 of 1 half dozen of another"
keep in mind one of the things allways mentioned here, not everyone will see a gain or the same gain & most mods work well with other mods
my truck was only getting just over 20 MPG's
and sluggish when i got it
now with the mods its got some decent pep
& i'm getting 24 MPG's
do the mods you want or feel best with
or do none at all, best part is
it's your truck and your choice
just watch out for all the sh*t floating around

Horse pucky
Pull your fuel pump relay use a timing light and
check your base timing should be right at 10 BTDC
Now do the mod and recheck it will be 13 to 14
All this mod does is change the base timing and
you will have that amount of advance accros the
board and it will not change anything else
The injector timing is trigered by a pickup in
the dist run from the crank timing chain cam gear
how can moving this sensor change that it CANT
The performance comps run a 8 degree advance
over stock
Here is a article on mopar mucsle magizine were
they used a race icon from superchips and
advanced the timing 9 degrees this shows you
how weak these trucks are with timing WHY so
you can run the crapyest gas you can find without
getting any ping
http://www.moparmusclemagazine.com/howto/40639/
Does moving this sensor change anything but base
timing NO THAT IS A PILY OF CRAP writen by some
misinformed idiot

Larry to the rescue!!! Thanks for the excellent info! How do these other guys get to state such things. I guess I never elongated the holes in my sensor enough to make the difference. Back I go again to see and try.

I've seen a pic or two that shows the holes in the sensor cut entirely on one side. Id this the normal way to do this? How far do I move the sensor? How would I chekc the timing if the fuel pump relay is out?

Unless you are planing on grinding on your bellhousing there is no need to open up the holes that far. The sensor will hit the housing and prevent you from going too far. That's why you can only get 3-4 degrees. As for direction, you want to move the sensor downward as you look at it from the side. This means that you want to slot the holes in the opposite direction or towards the top of the engine. There is no point in elongating the hole in both directions because you only want to go one way.
I think Larry is referring to static timing but I see no reason that you should not be able to use a conventional timing light. Since most engines no longer have degree marks it is hard to tell how far you are advancing the timing.

Any induction timing light will work just hook to
batt and #1 wire front drivers side.
Now remove the fuel pump relay from the power dist
box under the hood have someone crank it over and
read the marks on the vibration damper just like
you would on the older motors there is no module
advance during cranking and the base timing
will be from 9 to 11 BTDC this is a variance in
the sensor mounts.
slot 3/8 right out the end of the one side and
right upto the piece that runs down and holds the
sensor pull the rubber gromit out of the hole and
move down towards the oil filter
depending on the sensor you will now check again
and have 13 to 14 befor top dead sensor all this
does is tell the comp a lie that its at 10 but
its tricking it.
I think the guy was talking about people who try
to move the dist to advance timing which is
imposible on this system and than yes you will
need to reset the injector sync which anyone can
do themself with there eyeball
We have also came up with a new way to set this
cut a hole in an old cap and .030 from the #1
button to the rotor is +6 +or- 1 center is 0
over cyl line
The sync can only be changed by moving the dist
the V6 stock cam runs best between +3 to +6
with a hotter cam +6 to +8 if you go behond +8
you will know because it will trip a check engine
light
Advancing your timing with the crank sensor mod
and getting the sync between +3 +6 will give you
excellent throttle respose and better performance
accros the entire rpm range
Factory sets at _3 to 0 and will not go behond
this setting as instructed by mopar tech dept
but they know being on the + side they run better
such a deal hey

Hey Larry,
Can you go over that sync procedure again??
where are you measuring .030 and how do you ensure getting +4.

The sync is easy to set just put the damper on
TDC compression stroke rotor near #1 plug wire
Now there is a line on the pickup plate marked
CYL rotor button centered over line looking
straight down over dist is 0
The back of the button alined with the line is
+3 +4
Be sure to push lightly back on the rotor towards
the front of the truck to remove any play
If you have a old cap cut a hole in it and place
the back of the rotor button between the #1
dist lug and the back of the rotor this will be
+6 .030 feeler guage between the 2
Turning the dist counter clockwise advances the
sync + turning the dist clock wise retards the
sync -
Use a good light so you can see it good the G3
daks are a little harder to see

Larry,
I am having trouble grasping your new method for setting the sync. Can you provide some pitures or a drawing. Do you have any idea why DC insturcts the techs to not go past 0 on the sync?
Thanks

The brass incert in the dist cap cut a hole in
old cap between rotor and this incert .030 feeler
guage is +6
Just use the eyeball looking straight down
center over line 0
rotor button behind line back edge flush with
cyl line is +3 +4 looking from front of truck
rotor button behind cyl line and lookin straight
down over dist
The factory just one of there weired quirks that
they will not let them set behond 0
Going to the + side gives you way better response
and better mileage
The intake valve stock cam opens 8 befor TDC the
injector at 0 will fire at TDC your mising the
scavaging efect were both intake and exhaust are
open and the low presure area and exhaust pulse
will help pull in the charge fireing the injector
right from +3 to +6 as soon as valve opens pulls
the gas in better at 0 od - side you miss this
action and lose response to soon and it bounces
off valve to late and your using the piston down
stroke missing the effect of the low presure
area and exhaust scavaging
