don't know why but it is only getting to like 840 on the o2 mv i have only raised shift points and removed rev. i added 2*of timing but then took it out.it has cold air,pulley,cat back and throttle body spacer,and a dry shot if i can get it to stop running lean

 

oh what randy the 08 truck???

 

check the pe enablers.

 

yes it is

 

The stock narrowband sensors aren't always that accurate for a WOT reading. I have tuned many different vehicles including mine with the wideband for 12.5-12.8 afr at WOT and the narrowbands would sometimes read 840-870 mv at that afr.

My truck right now is dialed in with 12.8 afr on my wideband and my narrowbands are reading 850-855 mv.

 

That's a good point too.

 

got ya just checken and would like to richen it up a little to spray 100 dry

 

(b0155) for enableds says 300---pe commanded fuel is set at

0-----.85
down to
2048--.85
2304--.86
down to
2816--.86
3072---.83
down to
3840---.83
4096---.82
4352---.81
down to
5376--.81
5632--.80
5888--.81
all the way down

i was told this was way low any input on this would be great.

thanks ahead of time

 

What software are you tuning with? EFILive? I checked and don't have b0155?

EQ is a divisor not a multiplier AFAIK. So your PE table is set up as a multiplier.

Dividing 1.00 by the numbers in your table that you show below will give you the divisors you need to replace them with.

If your software uses a multiplier as an EQ then multiply 14.67 by the numbers in your table below will give you the equivalent AFR related to each.

ex. 14.67 x .85 = 12.47AFR.

or

in EFI Live 1.00 / .85 = 1.18 EQ

14.67 / 1.18 = 12.43AFR

So either way if you know the AFR you want to have for your wet shot you can calculate the EQ and enter it into the PE table for the appropriate RPM.

Make sure you set the TPS % and MAP Parameters that you want to activate PE. Set PE delay to 0.

 

it is efi live 7.23v

B0155----is in the parameters section under fuel.

ok i am going to try the stuff you said thanks
