I run an aftermarket ECU and wide band sensor, the wide band allows me to set a cross over point of its Narrow Band mimic output. So all i need to do to change the a/f is adjust 1 setting  my fuel maps are all around 14.7-15 and the ECU will pull fuel when crusing to get the desired a/f.
Im considering swapping the 3.54 diff for a 3.03 LSD at some point, that will drop revs even lower, a lot of my cursing is at -18 to -20 In-hg, so a little more load and lower RPM maybe help out even more. |
Ok, So your able to set a offset voltage to lambda to trick it from normal 14.7 .
If my memory is right you said your using haltech stand alone ECU ?
