Following this tuning guide, knowing its kinda old, I see in step #19 I need to create a Histogram. Well, I'm pretty sure its built into HPT 2.24 (histo#7), but my question is, do I need to add the filter to omit data less than 14.6?

 

Nevermind, I'll add it anyway. It seems that filter just omits any PE values if I get into PE.

Should I push PE up to say 65% TPS so Its less likely to trip? (for logging only)

 

I just logged a very short run to see if I'm doing this correctly. Am I actually short on fuel by %20+ percent in some areas??! Or did I set this up wrong?

 

Yes, you probably are short of fuel by 20% in some areas. Your VE table does look very low in some areas, so make the adjustments and do another log. Just remember to adjust the VE by half the reported error.

 

I am assuming I should not touch the VE table until AFTER we finish the injector tuning...?

I'll leave it as is for the next log. (8)
