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 decat 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

Re: AFR stuck at 14.7:1
The Euro spec ECU only has a narrowband o2 sensor. To get the lambda you need to connect a wideband.

Re: AFR stuck at 14.7:1
Use a PLX wideband and you can input it into the Analog input on the K-Pro board.
Re: AFR stuck at 14.7:1
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.
