JN's Minram Backfire UPDATE!

[JN]

Hi,

    Some of you have asked about my throttle position and O2 volts as to
weather it was a decel enleanment or not. Well......I just so happened to
record a backfire while driving (ie under load) and take a look at this:

TPS    O2        LV8        Pulse     INT        BLM
.61       88        38        1.3            128        122
.63       681      34        1.2            128        122
.63       44         35        1.3            128        122
.63        0           36        1.3            128        122
.74        0           44        1.6            128        122
.86        0            67        2.6            128        126
.90        0            77        3.1            128        126
1.14      496      117       4.5            129        122
1.49       0          184       7.1            130        122
1.67        0         105        2.8            132        122
1.69        841    137        5.0            132        122
.98           4        182        8.0            128        122
.76           889    100        3.6            129        122

This is with the pump shot tables increased by almost 3 times.  I might get
the backfire once out of every 15-20 throttle transitions but always a flat
spot that wasn't there when the Super Ram was on.  The above tables also
were at FP to 48 psi at idle and 55 psi vacuum line off with spikes to 60 if
you blip the gas.  What hey who is going on here?  Should I just hammer in
more pump shot?   Try the 30 pounders?  Also what is an Alpha N system?  Is
that fuel trims that don't use the MAF for trimming like early PE?

Thanks
Jason
