Hi all! I am Tim, new here. I have used LT1 Edit for a 95 F body very successfully.

I am putting an LSx engine into a rear engine dragster. I have been told at WOT I am in SD mode anyway... what's the deal about access to both spark tables using the SD OS? Can I use the SD OS and the two-sep feature simultaneously?

I am missing something, but I had just planned to leave off the MAF and tune it with a wideband first then take it to the dyno for final touchups and timing tweaking.

BTW - the LT1 liked 37 degrees total advance.... what are you guys seeing on 5.3 and 6.0 engines?
