New Haltech WB1

[Millsy]

How else would you do it Joe?

Also, does this calc.pid look right?

Thanks,

well when u get it fully worked out let me know. as i have a few to setup too. haha

That's just it, it can't be done unless both both devices (gauge, V2) have high impedance inputs (10 Mohms or greater)...

do an experiment: have both devices tapped in, and using a DMM measure the voltage... then remove/untap one device and see if the DMM shows the same voltage... if it does then you're ok;

if DMM shows a different voltage then you to avoid tapping directly... it won't be as simple as a constant voltage offset.

The calc_pids.txt is almost right...

add at least 2 blank lines at the end of it (after the last line of text);

also note that the AFR units is already defined, so you don't need to define it.

What stoich AFR does the Haltech assume (does it assume 14.7)...?

If you know this, you could add lambda as well...

For example:

. . .
*CLC-00-001
V                  0.0           5.0       .1  "{EXT.AD1}"
AFR               10.0          20.0       .2  "{EXT.AD1}*2+10"
lambda             0.5           1.5       .4  "{CALC.AFR_WB11}/14.7"
. . .
CALC.AFR_WB11     F001  CLC-00-001    "AFR,lambda,V"    WO2-Analog    "Wide Band AFR 1 - WB1"
. . .

and same for CLC-00-003.


[ there are various reasons to use lambda, see the Calc.VET thread ]

Thanks for your help Joe

Thought I would give you guys an update,

Re wired the wideband connecting all the negatives/grounds together

Laptop is now seeing correct AFR for plx calc.pid I.e. 2.25v AD1 = 14.5 AFR

The gauge does however read about 0.2 - 0.3 AFR higher so I just ignore it when tuning

Thanks to everybody who took the time to reply,
