Getting the LT1 files to work.
The following is what I did to get the Evaluation version of EFILive V4 to work with my 94' Camaro Z28 (LT1 with a M6 transmission). For reference, I am using the Andrew Mattei cable that I bought when I got LT1Edit (standard MAX232 cable).
To get the software to talk to the ECM, I ended up removing the length parameters for the Mode $01 macros. Once I was able to get this to work, I noticed that for Mode $04, there was an error with the Spark Absolute command. After reading the Mode $04 documentation (under the Mode $04 tab), I noticed that for the Spark Absolute command, it should be a $01, not a $07 (that is the command for Retard Delta).
I hope these things that I found will work for others so they can also use this great tool.
