Well... that sucks

Looks like a high octane kaboom map my goodness.

 

Holy jesus... can some one say steady 10 knock counts from cruise up... that is just uncalled for! Are you telling me you heard no audible knock while running this?

 

who tuned that!!!?????

thats one hectic page of "i know **** about tuning"

Your tune looks lot better. I see you have big maps in the back ground? are you going over to that?

if you are, I would work on transition timing as well as actuals. if the transition is too big )3 or more degrees) then you can bring on knock.

try stay under 3. noticed it in the big maps 6-6500 and 7-7500 in the last 2 columns it is more.

WTF, 20+ degrees at spool-up. Man that had to be knocking like mad. Should have been pulling timing all over the place.

 

is that a diesel fuel tune?

 

Looks like the map on the left is a bit optimistic?
