Tuning Question >> what spark values to use?

DMX

Registered User
I'm using the eec tuner do get everything running properly on the m90 in my Taurus, so far so good, got the system setup for the ProFlow maf and the 30# sc injectors and everything is running great.

However i'd like to do a little more with the power tuning
I've got the load tables rescaled and setup the fuel tables so that i'm seeing 11.9-12.1 from idle to 5K at WOT.

What kind of spark numbers seem to work best for you guys?
I've got something not too far off stock, my WOT advance vs rpm table looks like this.

Code:
RPM                 Spark Advance
16383.75    26
5000           26
4000           25
3000           22
2000           20
1800           18
1500           16
1200           14.5
0                 14

How does that look to you?

the base spark table (vs load) looks like this


Code:
     RPM (x axis)  (Load Y axis)
RPM  > 500     750     1000    1500    2000    2500    3000    4000    5000    6000

There isnt a single dyno in the area, i'm sure its like that for a lot of you guys too so everything you learn pretty much comes from stock eec files.

Any glaring errors there? I dont know for sure if i'm on the high side or too low and can advance more, or if the load values are wrong or anything, got any tips? A lot of this info was copied from/based on the STOCK m2y eec file for the supercoupe, i'm sure it can be tweaked more.

Got any tips? or raw numbers that have worked well for you?
 
Your numbers aren't bad. If you want you can set the knock retard to -0- and then advance till you hear pinging and then drop back a degree or so. Reset your KS to -6- and call it a day.
 
aaah, see thats it, no Knock sensor on the taurus :-(

Thats why i was looking to see if i was on the ragged edge of too much timing, or if i had plenty of room to safely bump it up some.
 
those values are all higher than im running on my 89 sc
with 30 injectors
