MG ZR: Cams & Maps

[lolsteve]

They are very easy now I know what I'm doing. Unsure how I did them in the past, might have just gotten lucky but now I can whip off the belt and have it all redone in an hour including set up etc


I'm still not happy with the idle/running though. There is something wrong somewhere I'm sure of it. Swapped out the coilpacks and o2 sensor for spares with minimal improvement.
Plugged in the obd reader and watched the o2 sensor voltage / fuel trims.
Voltage seems to be hanging around the 0.8v area (rich) and the long term fuel trim was a good -8% while the engine was warming up (1000rpm) then when it went closed loop it rose up to -12.5%  . Was at -13.3 yesterday and I think that was the maximum it would go hence the EML light and code P0170
