Merry Christmas everyone

Hey guys now for some reason on hptuners i cant put in a negative offset ??

For the linear and offset i got the specs

linear 312.50
offset -11.25

it wont take a negative -11.25 only positive ??

anyone have any idea what it can be ...
its a hpt custom 3 bar opertaing system

12592618 converted to 1260058 3bar

You can't enter a negative number for the offset value in older PCMs. That's why I never use the LS9 sensor with older stuff.

ok cool makes sense .... i tried to tune it out but it didnt work well i got weird problems running that sensor and wasted alot of gas lmao

I installed the duramax sensor last night and put in 333.33 and 33.33 now i need to redo the ve table ... going to be fun...

I heard that the duramax sensor was not really good in vac is that true ?

How many people running that sensor any issues ?

Thank you

I have the older and newer style duramax sensor ...
I am assuming the newer one is better ?

Would have been so much more helpful to know that HP tuners can't do this. just machined the spacer spent 3 hours installing it, rewiring the harness.

Running same #125 bosch sensor 3 bar. in a 2002 v6 4.3l ECU 0411

Please tell me HP tuners has stepped up to solve this? I read earlier I needed an update to accept negative offsets. Running Version 2.24

Update your software. HPT allows a negative offset now.
