Does now!

We have made a firmware fix for jittery A/D inputs. The FlashScan firmware now 10x oversamples the A/D inputs and averages the input data every 100ms. That conditions the incoming data and provides a more stable A/D value to the EFILive software.

I've attached the firmware with that update here. Unzip the file into \Program Files\EFILive\V7, then run the firmware programmer to update FlashScan's firmware with the new V64 file.

Hey Paul... I'm suffering with this.... Ross just e-mailed me and wants to know why I'm e-mailing with him and what I'm going up at 3:30am us tiime....

ANSWER: I'm dying! Please get us serial AFR into V2 soon!

Is this firmware current or do I already have it from another update?

Thanks
Chuck

Does post #2 of this thread help: showthread.php?t=4593

I've checked the offsets on both my wide bands, both read around 0.03 volts lower than the programmed 1V and 4V output from the LC-1's in EfiLive.

Would the process you describe remove the 0.03V negative offset?

IIRC, it should get it to within 0.02V which compared to 5.00V full scale is 0.4% error.

If it is consistently -0.03 off, would adding 0.03 to the calculation in sae_generic.txt make it read correctly?

Right now it is:
# PLX WBO2
# ========================
*CLC-00-920
V 0.0 5.0 .1 "{EXT.AD1}"
AFR 10.0 20.0 .1 "{EXT.AD1}*2+10"

Why not make it:
# PLX WBO2
# ========================
*CLC-00-920
V 0.0 5.0 .1 "{EXT.AD1}"
AFR 10.0 20.0 .1 "({EXT.AD1}+0.03)*2+10"

A better bet would be to add .03 to a calculated PID in calc_pids.txt. This file will not be overwritten with future software updates whereas sae_generic.txt will.

[Ninety8C5]

Sounds like a better idea.

[joecar]

I like that idea also.

[Gelf VXR]

Great, I'll make the changes in the calculated PID, thanks
