Accel. Enrich %BPW Factor vs. Async Pulse
That's the table name in TunerPro.
Notice the 1st pulse is 0 and the 2nd is 0.25 on most stock bins. Well I found better throttle response (noticable to me and a client) by changing the 1st pulse to 0.25 and the 2nd to 0.4 . I just thought I'd share that bit of info if it helps anybody. I think that table needs to be modified when you start dealing with faster reacting motors. This engine I was tuning had $600 worth of TPI parts, Lt4 hot cam, and headers. Everything else was stock. The car now has the ability to snap the throttle open and light the tires just as quick and then control the tire spin through throttle modulation as apposed to before where the throttle snapping open would cause a small delay and lean spike.

 

Very simliar table in the $8D.

Wonder if that could be the same issue I am having on my tip in lean spike also...

Have to play when I have some spare $$$ for the tank.

Thanks. Will try it out.

 

My ARAP BIN shows 0.5 for all 8 values.
Anybody else?

 

ARAP = Y-body bin. I should have been more specific and said stock f-body bins.

 

Thanks for the info JP.
Every little data point helps make the picture become clear.

 

Agreed!!! Do you by chance have all your 6E code information all stored in one location so you could post it in the stickies section?????

 

How does the car run?, it's what makes the engine happy, that counts. A tip-in leaness isn't necessarily bad, if there's a lag, orthe plugs are showing signs of pre-ignition then that's what counts.

 

FYI,
The AUJP $8D table at 53B has the first point at 3.98 and then filled with 0.500 for the rest of the way.
