Hi guys,

I'm wondering if anyone has experienced a similar issue?

Done the wasted spark/closed loop conversion

The car will not go into closed loop at idle, has anyone else had this?

I'm running an independant bosch closed loop lambda sensor (not an output from a wideband)

The TPS is set correctly (0.25° at closed throttle via IAW monitor)
The base idle is set correctly (900-1000rpm with ISCV unplugged, coolant temp of 88°C)
The CO screw has been reset and adjusted but makes small difference

It idles at about 12.8:1 AFR. When I put the lights on, and the fans cut in, it leans off to about 14ish, but I'm going to do this, then unplug the lambda sensor, to see if it IS in closed loop at this state or not

The closed loop works everywhere, when driving, that it is supposed to, from what I've seen so far

The only thing I can think of, is that maybe the fueling in the map, is over 40% out at idle, and the closed loop can't correct it enough


Any ideas are more than welcome
