Hey
I remember you from the past ... Its Jeremy ... IIRC
Where have you been as I don't remember seeing you post lately
alright, i got a few questions. basic stuff.
ive never checked or had the timing checked on my 95. what is it suppose to be? i have heard that by bumping the timing, some guys have noticed a subtle difference in performance. what can it be bumped to (safely) and is this true?
The OEM setting on the dizzy is 10
Yes ... It is possible to find some more get up and go with advanced
settings at the dizzy
however
GT stangs have high values in the mid load range of their spark table
therefore
You won't be able to go much before you hear the ping thing
I'd add 2 and see how it goes
then
Drive it a couple of days listening for ping
then
If no ping ... try a couple more
and so forth
When you hear ping ... go back down 2
You most likely can go more with 93 grade gas
and
A smaller amount of advance with the lesser grade of gas
also, doesn't our cars retard the timing between shifts? please explain how this works and if there is a way around it. if it didnt retard timing, that would help some too, right?
Well ... Yes and No
on the shift retard as many peeps mistakenly call it
You ask how it works
so
After we see how it ... REALLY ... works ... You'll see why its misunderstood
Say you are in third gear on level ground at a steady rpm of about 1500
This condition will put the throttle just barely open
and
You will be operating at a very low load condition
To evoke the retard ........
all you gotta do is go to the floor with the skinny pedal
You'll encounter a spark retard to the value of 5 for about 1/2 second
The action that caused this event to happen is ... NOT ... shifting
What caused it to happen is the ... tipping in ... of the throttle
hence
The ... CORRECT NAME .. minimun tip in spark retard
Yes ... It can happen during a shift
but
Well ... That just don't tell folk
The WHOLE story
It can be done away with by changing values in the pcm
and
It makes a difference that can be felt for sure
You could bypass the retard with a power shift
cause
You would not have any throttle tip in on the upshift
but
You'd be doing a thing your t-5 would not like one little bit
currently i have 120k on my stock 5.0. i have the following mods:
mac shorty headers
o/r x pipe
spintech prostreets
crappy ebay cai w/fenderwell no-name filter (i wonder if this hurts more than helps)
msd coil(recent)
msd cap(recent)
frpp 9mm wires(recent)
autolite plugs(recent)
frpp 4.10
centerforce II clutch
motorcraft fuel filter - done at time of tune up
walbro 190 pump - factory pump got way loud
few other things but nothing performance related. the car runs great but is just....slow. or slow to me anyway. back to basics here - whats my next options that might improve power without hurting the wallet?
lastly, your thoughts on performance chips. moates, hypertech, jet, etc.
grady posted in the original post that no one should be slandered for any question....so, go easy on me
Not sure what your long term goals for the car might be
but
Staying within the bounds of NA and tight budget
Here are a few ideas or two as I see it
Pulleys ... You'll pick up torque ALL across the rpm range
CAI ... make sure it pulls in air from the fender
when the temp is cool ... you will feel a difference
when the temp is hot ... no difference
Roller Rockers with a higher ratio like 1.7
but
Honestly ... Don't expect more that 3 to 5 rwhp
therefore
I've never seen that mod as being very cost effective myself
Where I think you would pick up some noticeable power
would be with a long runner intake such as
OEM Cobra
Edel Performer
TFS Street Heat
About tuning ..........
Store bought chips are gonna do next to nothing or nothing :Word:
Moates is a method where an optimized set of values are loaded
on a chip ... so you see ... That is a custom tune
Of course ...
The effectiveness of that method is in direct proportion to the amount
of knowledge one commands to know how to modify the pcm
Well Jeremy
Hope something we've talked here about gives you an idea or two
