Lt1 Ignition Table's

[EFISYSTEMS at aol.com]

Hi all,
     Just a thought from experience,,,,,the reason it seems to want more fuel 
in the lower gears is from a number of reasons but the basic theory is: It is 
in a transient vs. time experience. The time the processor "figures" it out 
and the delays in the wiring and injector movement is completely unlike a 
mechanical carburetor....but it can be overcome with tables for each gear as 
you speak of........you know NHRA has been willing to have efi in Pro Stock 
for quite some time but they feel it will be an unfair advantage to those 
that have the money........it will be a great learning curve for some........

 I assume it is using the rpm/25 for the 400-4000 and the rmp/31.25
 above 4k on the 94-95 models also?   That is what mine seems to use
 for most table indexing.  I have not yet really looked for the spark
 on mine yet, I am still improving things playing with the fuel.  I
 have successfully split fueling out for each gear, so I have a
 separate table for each of the 4 speeds.  I don't know how much this
 is going to help things.  I have noticed that while tuning to a
 certain O2 value, the car seems to require more fuel (higher
 constantt) in lower gears to maintain the same O2 output level.  I am
 also tuning by performance and so far leaning thigns out has speed my
 car up.    I need to do some more this weekend.
