Driving the car is fine and afrs seem normal . Car idles fine too apart from the lean afr reading .?
It is a modded 940 turbo with to blue injectors and 16t turbo etc etc
Also noticed that a ballast resistor thing is getting very hot is this normal ?
I think its a pre injection ballast or something?
I've already done the resistor mod for the injectors
But this is another one ?
Any help be much appreciated

The ECU needs time to relearn the fuel trims which you erased by disconnecting the battery.
The second resistor is probably for your dim-dip so will get hot, that's why it's aluminium clad to disperse the heat.
