ive got a couple problems in my tune and i cant figure it out on my own for once i havent had troubles before while tuning in the ve and maf. im trying to run my truck in CL with the maf and everytime i load it back from OL, it goes rich and lt fuel trims just keep on truckin on the positive side even when w/b is showing 13 or richer. i have been going back and forth, checking the ve table and the maf airflow to see if there were errors but they are all -5 to +1. i checked my offset voltages on the w/b and also, free aired it a couple times. i posted my latest tune and log.

 

So u first tuned the Ve, then the maf table. Did u make sure ur IFR is right, if not stock anyway (didnt read sig)

 

You are commanding stoich of below 14.68 in your stoich AFR table.?? Don't know if that would drive LTFT's though.

 

it is an e85 truck so, the stoich table is gonna be different. richer the more alcohol content.

 

yes, i tuned the ve then, the maf. my injectors are stock.

 

did you or do you need to reconfigure you wideband for the e85?

 

im not running e-85 im running 87 octane. i have only run 1 tank of e-85 through it and im thinking it might have taken the w/b out.

 

You could toss my WB in your truck to test if you want, I am not using it and my new one arrives tomorrow!!!

 

i actually have an lc1 kit here at the house for my buddies build. i think i might steal the sensor from his and give it a shot. hopefully it works. if not i wouldnt mind using yours if you dont. you think you could have justin look at the tune and pm me?

 

Just let me know if you want to borrow the WB, I wont be around much this weekend and I will be leaving on Monday for a week so I wont be around and or needing it, you could compare it to your LC-1...
