Wiring LC-1 Wideband to Kpro

fabiangt79 · Post by **fabiangt79** » Wed Feb 16, 2011 10:37 am

I tried to wire my LC-1 to kpro on my PND DC5 ECU.I wire in the E15 of the ECU connectors, it already had a original wire from the car wiring to it.

I change the settings in kpro to using external from ELD pin.The AFR is running in my Kpro but not accurate compared to my logworks.

Tried some offset but did not work well.

Car was idling for some time and suddenly the ecu had no light running and i could not datalog or download any more from the laptop.

Can someone tell me if the yellow wire from LC-1 link to the ECU E15 ELD had cause the Krpo to have problem?

I discconnect the LC-1 wire and it was still the same?

Can someone give me a guide on how to wire the LC-1 to the kpro and what voltage or settings i need to do in the kpro to get the accurate AFR?

Did you cut the wire at E15 so that it no longer goes to the ELD?

No I link direct to the e15.could that have been the cause?
After I cut the e15, what are the settings required in the kpro?

Please advise in details the settings for wideband input, I do not want to fry the kpro again.

Thanks

You must cut the wire. The insturctions on our website are for an s300 with a PLX wideband, but the idea is the same, just substitute the K-Pro inputs.

Check this out. You may need to create conversion table for your lc-1 / ecu combination. If not done, AF readings are wrong. How to level voltage on lc-1 is in the lc-1 documentation pdf.

I am unable to input the conversion into the table, it is highlighted in grey and does not allow me to edit.

I selected the external wideband from ELD, still cannot edit and also all the quick select and still cannot.

I cut the wire but still not accurate.

Just select "Custom" from the "Quick select" dropdown menu.

Here is procedure how to do propper LC-1 calibration. (Translated form Czech to English via Google Language Tools)
