Hello Hondata,

I'm struggling with correct setting with my PLX boost sensor input, which I have connected through KPro III digital input. I have PLX AFR and boost sensors in the chain and AFR is read just fine. AFR is my DI0, boost DI1.

I have two issues with DI1 (boost):
- KPro reads boost values in the strange scale (not linear), for example: MAP sensor reads 17.24psi and DI1 reads 971,75psi or MAP 20,06psi - DI1 1841,98psi.
- KPro reads only when there is a boost (when vacuum, then it reads zero)

Please find screenshot of my digital input setup attached.

Please suggest. Thanks.

How exactly do you have these wired? Is the terminator installed? Where is the terminator installed?

Yes, the terminator is installed and it is in the boost sensor module only.

The chain is like this:
boost module (with terminator) TX => afr module' RX (no terminator), then afr' TX => KPro digital and DM-6 gauge (y cable split)

DM-6 gauge shows vacuum/boost values just fine.

Post the calibration as well as a datalog showing the issue.

Calibration and datalog attached.

Thanks.

Try connecting just one digital input at a time and see if that works.
