Softballnrd,

[70c10]

Shaun, thanks alot for taking the time to run this for me! I have three questions about the program:

1. Can you tell me why it says in the notes- Spark Knock? I've never experienced that and I run 42 total degrees.
2. Says my A/F mixture is very poor?
3. Am I reading the graph correct in that my optimal 1-2 shift is at 6000 and my 2-3 is at 5900?

Thanks again!

1) What fuel do you run? I have it running 91 octane.
2) Not too sure..
3) I need to go back on everyones ET's as I forgot to let it tell me optimized shift RPM for 1-2 and 2-3.. I'll try and knock that out tonight after dinner as it won't take long having all of your guys data saved.

[Super73]

Ok.. Everyones shift points are more or less optimized now and the ET's you see should be a good baseline..

How about the xr288hr

Any chance of doing mine? Thanks-!

can you advance/retard cams to see how it affects the output? be curious to see the differnce in my that and bigger rockers on my 383 LT1 build. also not sure if an LT1 ported stock intake is considered single or dual plane
