Ok so I'm trying to get rid of the EML, iv just completed the auto manual ecu mod but its still there,
Iv just checked it and its came up at code 41 if iv got it right

41 Primary Heated Oxygen Circuit
Circuit Malfunction
Open or short in Primary HO2S sensor heater circuit
ECM

So exactly what is that, a lamba sensor fault?? How can I cure this OR will it not cause any running issues ie; Vtec not kicking in or something along them lines

Your O2 sensor several wires going to it from the ecu, one of them has a break or isn't wired correctly. I had this exact same thing when I installed my afc2 and accidentally pulled one of these wires out of the connector.

Code 1 is a faulty O2 sensor itself

God dam it!! Haha so basically follow the 02 sensor wiring to find a brake or could it be if the 02 sensors not connectered fully..

Iv not touched any part of that sort of wiring

Well the auto vrs manual and bb4 vrs bb1 ecu wiring does differ, could be something to do with that? When I get on my pc I'll post the link I used with the different wiring pin outs
