Default 383 Stroker Logfile!

Can someone look at this logfile and tell me what's wrong with it?!

Thanks!

Its really hard for me to make sense of this log to be honest.

Your fueling seems all over the place. And deffinately wild splits between banks ie at a couple of points you have one bank BLM 108 and the other BLM 160. That indicates fully rich and fully lean.

Unfortunately I think all we are seeing with your BLM readings are the missfires. Missfires will show as a LEAN condition and the ECM will add fuel to try and cure it.

Also I suspect that your TPS is not reading accurately. I beleive you probably went WOT a few times but your only showing 60% TPS. I think you need to check the voltage at the TPS directly as that could be causing all sorts of issues.

Yes, it's crazy how much it splits! The strange thing is, that the TPS is brand new!
