The fuel enrichment crap I took out, so it doesn't add none. What do you about keeping spark low??? You mean to keep spark low to set my a/f and then add spark???
Yes ... talking about WOT fuel ratio adjustments
and
Talking about running 93 grade gas for WOT af ratio dial in
I'd run around 28 maximum total advance while doing maf tweecs
after you got a nice & fat ... flat ... curve established ..........
*** I'd move up to around 12.50 to 1.00 and start to add in more spark
a couple at a time all the while listening for ping
You'll end up in a range of 32 to 38 for best wot spark
and
A range of 12.50 - 13.00 to 1.00 for best wot fuel
Of course you will have to experiment to see what your combo likes
If using your "seat of the pants" meter and "ear" ping indicator
along with datalogging on the street method ..........
Find out if you got ping anywhere while doing the *** thing from above
and
Since you got Aluminum heads, I don't think you'll hear ping
Now ... from this point on ... is where the experimenting takes place
and
It kinda goes like this
Say you heard no ping during the *** thing
back off the spark value 6 degrees
lean it out from 12.5 to 12.75 and listen for ping at that reduced spark value
then
go up with the spark 2 at a time to see if ping occurs at the leaner ratio
Can you see the method to the madness here
#1 objective is to ..........
Get your spark table setup for a match of wb display
which allows you to simply fill in the blank (top row of cells in fuel table)
for desired af ratio
as opposed to
Doing more tuning every time you wanna go leaner or fatter
When you did the *** procedure the first time
you accomplished
Finding a maximum spark value while still being safe ... or ... a bit fat
When you did the *** thing the second time
you were starting to sneak up on the fuel a little at a time
while
doing the same with the spark value
Basically ... You sneak up on the final values of fuel & spark a little bit
at a time when dialing in that last bit of WOT performance.
Hope that makes sense
and
If it don't
Ask to make sure
cause
This is where you wanna be sure about what your doing
