Go to accels websight and download the tune they setup for there 454 crate motor setup, That will get you real close to start. Then from there just fine tune it. You dont' need Alpha/N mode. You also need a wide band before you can really tune anything for WOT. The narrow band will get you close. Look at the fuel trims and try to get them close to 0 by adding to the ve map to richen or lesson the Ve map to lean it out.
Before you can do this, you need to setup the commanded AFR map first. Idle should be about 14.5:1 through most of the map untill about 3/4 throttle where it needs to progressivly richen to about 13:1 afr at WOT. Also rich up the low vacume area of the map when you are accelerating hard progressivly to 13:1 also. After this, tuning will be a breeze.
Do you uderstand my extremely fast poorly written instructions??
