    I realized that $42-1227747-V5.2.adx and $42-1227747-V5.9.3.xdf are the files to use. These files are loaded with parameter information. THANK YOU to whoever has written and added all that info. I disabled EGR, with the patch provided, since I removed EGR. I disabled Air Diverter. I unchecked Pass EGR. I unchecked Code 32 so I don't get a CEL. I changed stoich from 14.7 to 14.13 because of E10 fuel. I changed Max Spark Allowed from 41.84 to 36. My 5.7L is not too far from stock. 9.4-1 CR, Melling MTC-1 Camshaft, Shorty header w 2 1/2" out the back. I think I am just going to kick up the fuel pressure a few pounds, add a little BPW, fire it up and tune from there. Antone see any problems with me doing this?

    I would not have reduced the spark timing allowed. That setup easily needs that much timing in certain areas. Think low load, higher RPM. I have areas in my 350 Vortec Express van that run 48° of timing. I also would not kick up the BPW. Stay stock or reduce it when you up the pressure.

    I have not started it yet. I will put the timing back and reduce the BPW. If I remember it is 135. Should I reduce it 10%? I do not understand exactly what the BPW and Spark Advance Hack would do for me. Is it strictly for information? Thanks again. I appreciate the help.

    The spark advance and bpw hack inserts those values into the aldl data stream for monitoring in a data log.

    Getting ready to start my engine tomorrow or Tuesday. I will need to break in the cam. I have a WBO2 in and working. I am hoping that I will be able to run some where around 12AFR for the break in period. Don't want to burn up my ceramic headers. Will it be okay if I wait to adjust IAC and TPS until after the cam break in. Thanks

    I am needing some help. I have loaded an AMUR .bin file into TP5. I have loaded $42-1227747-V5.2.adx and $42-1227747-V5.9.3.xdf data files also. When I call up the dash to see TPS values and battery voltage I have no values. If I look at sensor values it has Bogus info, a high coolant temp, a vacuum value, open loop status and some others. The engine is not running. ALDL is on Com4 and cable checks out good. Any ideas for me?

    What's the check engine light doing? It sounds like either the ALDL connection is bad or the chip didn't work.
