Hi all I'm new here and may be asking a stupid noob question. I have only had my kpro v4 a week and have not had it tuned yet just a basemap but it has never changed AFR from 14.7:1
I have a K&N typhoon intake. 4-2-1 japspeed down pipe. 2.5" exhaust pipe with a skunk2 backbox. A switch wired into E29 to turn on and of pops and bangs. Other than that every thing else that affects the ecu is standard.
I know its proberbly just a setting i have wrong or because i dont have a windband o2 sensor but i hope you can help

- what vehicle you have -2004 EP3 uk speck
- serial number of your K-Pro- 56446
- version of software being used (from Help, About) 4.4.4.0
- ECU part number (37820-pra-e12) and serial number (237981-4311)
- when and where you got the K-Pro - 03/03/2021 from CPL racing uk

The Euro spec ECU only has a narrowband o2 sensor. To get the lambda you need to connect a wideband.

ok thank you I thought that might of been the case I was just expecting to to see slight switching not static. so I'm sure you have answer this before on here but here go's
what is wideband senor should I fit and what wiring diagrams do I need for a PRA ECU.
thank you for your help

Use a PLX wideband and you can input it into the Analog input on the K-Pro board.

cheers thank you for that. out of interest I'm not bothered about fitting the afr gauge can i just get the bosch wideband o2 sensor and fit that as a plug and play or wired into the analog input

No, you need a wideband controller for it to work.
