Here is my Cam Analyzer results for my TW-555 with a 4 degree advance gear..What do you guys think..Looks like 2 is the start of IVO

also with the cam selector tool in TTS do I add the 4 degree advance to the IVC also??
tw-555 specs are ..Intake Open 21 ..Intake Close 41.. So I would change the close to 37 because of the gear right??

Thanks

 

All I ever did with my TTS, is select the most close build to mine, depending on year, which because I have the Axtell 107, Woods 400-6, SE 58 mm TB and D&D Borzilla requires a pretty general selection.

And go from there. Works OK. All you can do really.

 

Looks like your first most steep incline is at 3. Do not compensate for 4 degree your computer already did it.
Try 2 if you are not satisfied with the idle quality or performance.
I have the 555 also and found 3 works best for me. I tried 4 and the idle was rough. At 2 the power was lazy.

 

Looks like 2
