There is not universal map for every 8, I think you can add more fuel in to prevent the long term trim kick in (for 7.5k->8.5k).

and what exactly does that mean?????

if the ECU found out it is too lean and it might caused detonation, the ecu wil retarted the timing or will inject more gas in to prevent detonation.

if this continue to happen, the ecu might use Long term fuel trim to fix the prob. it means that the ecu will rich up the mixture again (by modify the fuel map). You can always reset the battery to reset the long term fuel trim

You really don't add fuel with this setup...all you do is take away less. The PCM already will add more than enough :D

Adjust the WOT line at the RPM you want and make the #'s smaller, and you will take away less fuel IE: change a 23 to a 17......

I'm Lost In Space.....

What happened to Holley 850 Double Pumpers, Crane Fireball 515 Lift, 302 Duration Cam Shafts.... And "Q" Code Intake Valves on.....

OK, sorry.... Back to the thread :)

oh.. ya. my mistake. sorry ... :P

modified ur airflow map. lower then number like dennobre suggested.

OK, I'm starting over...

Kinda like this...only with NOs :D

just cut the gains by 1/4 and slap a racing beat sticker on it and everyone will worship it....

...ok that was just bad :cool:

Still waiting for an answer as to what pinging is and how to detect it??? :o

i never had my car ping (official name - detonation), but it would sound like popcorn popping under your hood... the knock sensor should pick it up before it reaches that point and richen the mix and pull timing out to prevent it

In Excel, change the scale of your AFR. Double click on the axis and go to scale, type in min of 11 and max of 15, then repost this. It will give you better resolution as to what is going on. Like this on mine attached.

As Requested zoomed in to see even closer what is happening :D

Woah! That's what I thought - you need to add fuel on the those lean spots.

:eek: How do you like the header?? How is the sound level??
