Just having a look on Jeffs site for some pointers on tuning my Emanage with regards closed loop operation and I came across this, the Spyder VR4 fuel map;
As you can see on the map, low load and low throttle inputs command an AFR target of 16:1+, what we`re seeing on the widebands. I`ve gapped my plugs under book value, maybe that along with the lean condition which is mapped in at the factory is causing my miss?.
If you could map it just right, to bump the fuel into the 15`s where the ecu is not in closed loop operation you could effectively map out the lean spot without the ecu trying to correct your alterations?.
Putting my 450 injectors in tomorrow with the hotwire mod, then I`m off for a datalogging session to see what`s up.
