A/D Converter & PLX SM-AFR

Post by zrated »

Hi Guys,

Just started using Nistune and I'm pretty impressed thus far. I purchased an A/D Converter from Matt and have been trying to get my PLX Wideband Controller (SM-AFR using the analogue output) to work with Nistune.

So far not much luck.... I know the wideband & the A/D Converter are both working fine as I can use telnet to manually request the output voltage of the SM-AFR and all is sweet.

The wideband voltages are the same as the other PLX devices as it is linear; 0V = 10AFR up to 5V = 20AFR.

I've configured the afr1.csv & the aux's as shown
AFR
0000,10
5000,20

When I get into Nistune and open the Wide Band display, it doesn't read right. Instead of showing 20AFR (5V) it shows 12.04 and when the sensor is unplugged it's supposed to read ~2.35V (~14.7) but it actually reads 10....???

Can anyone help me out? :oops:

Just a note there was a problem with the older version displaying AFRs for this unit

Code is updated now (latest is 0.91123 as this time) which has the AFR display fix
