Tuning Help!

coryf79 · June 11, 2010

I am trying to add some timing(not too much 2-5*) in the "alcohol correction pe/cot" table, for when i run E85..

what i am trying to do is bring the alcohol correction table ONLY when i have e-85 in the tank..or when i am commanding a stoich near that of e-85

My question is under the gas and alcohol spark tables there is a table that's called "multi vs composition" (screen shot attached) I am aware of what interpolation means.. but what do the values represent?? is it injector duty cycle? and what do the values adjust? Anyone know this?? Or am i in the wrong ball park?

IF so, is there logic in the VCM that commands the pcm to use these tables other than if it is in PE?

Forgot to add, this is HP TUNERS by the way
