Can PIDs be modified, How ??

Ever heard of calculated pids (http://forum.efilive.com/showthread.php?2990-Collecting-links-to-tutorial-material-scattered-in-other-sections...&p=130988&viewfull=1#post130988)? :hihi:

yeah so how do I offset the the built in LC1 AFR PID ?

What exactly do you want to do? ;)

I'm trying to get the serial AFR (log works) to match the analog AFR (EFI Live v1)
I know I could use LM programer but It's not my car so I figured I could just
Change the PID and the data would become valid ?

It will never be identical to serial no matter what and ideally you want it to match the PCM's AFR value for EQ/Lambda 1.00
You need to know the LC-1's programmed analog setting for the the output connected to the V1.

Read through the bottom link in my sig.

I got it !! I can add or subtract from the added value.

"({EXT.AD1}*3)+7.35"

Whats that look for ?? Are you really a prick ??

My concern is you don't skew the pid to get data you want to see and ignore reality.

I'm not judging. :angel_innocent:

yeah....I think I'll just walk him through how to use LM Programer and make sure the supply voltage is
correct. I have a question tho if the low is 7.35 and the high is 22.5 why does that calc pid list the
low as 10 and the high as 20 ??

The 10 and 20 listed in the calc pid are the min/max display limits on a chart/gauge;

you can set the display limits to any values you like, I set them so that stoich is right in the middle of the chart.

If the LC-1 has the default AFR/Lambda settings you can add this to your calc_pids.txt

#Units Low High Fmt Expression
#------------ ---------- ----------- -------- --------------------------------------------------------------

lambda 0.00 1.60 .3 "({EXT.AD1}*0.2046)+0.5"
