Kpro v4 and digital input with em 30-4100

[olivenoire]

Hello everybody

Is kpro v4 able to be used or not with em 30.4100 in digital instead of analogic


I need to tune or drive in wideband closed loop and I'm not sure the so much fluctuation of analogic is good for

If yes, can you simply tel me if what color need to be plug to what color.

And in kmanager, wath to do ?

Sorry but digital input in kmanager can't help, even help file

Regards

PS : is somebody succeed in wideband closed loop, with AEM or PLX ??
PS2 : I bought AEM, probably PLX is by far better or I don^t know but I will stay AEM

You will have to contact AEM for the manual for that wideband as I have not been able to find any details about that one.

Thank you for your reply. Obvisouly it does not work.
I've try white and blue wiring of the gauge with 4 wiring :
RS232 Rx Green RS232 serial receive
RS232 Tx Brown RS232 serial transmit
TTL In- Grey TTL serial input (inverted)
TTL In+ Purple TTL serial input (normal)

None of them gave a signal. In fact I wonder what is the digital input in pro v4

Seems it is possible using hyper terminal etc... Nonsense...

Finally I've decided to use the analog input with white wiring.
Ti avoir 0.7v offset i decided to place the ground of the gauge the same as ecu
I still need 0,1v offset but seems good enough for live tuning
I was able to drive with AEM wideband gauge and everything seems fine.
So kpro v4 in first step worth the money :)

Hi

I was not able to tune using digital. I can't understand why 30-4100 is reachable in menus but nothing happens...

Anyway I've decided to use analogic. But I can see what I believe to be a slightly difference from what I read from the gauge and what I can read in kmanager
0,1 offset seems to be good.
I need to try once again with 0 offset but seems not so good.

Actually I'm using my wideband but want to have proper AFR map in case this one would be defect
I would like to know how to autotune. I've tried using "live" button and "autotune", but no sound, nothing change

[olivenoire]

That's what I will do. I need to do some full pull, i'm not so bad but want to improve

[olivenoire]

Come back after a while....
In fact my k20 is now in very bad state , bad sound probably in valve train...
Need to open it

I will try this improbable feature of livening or autotune later
