newbie EMU guidance..
#22
Possible but you would need to slap something together.
You'd either need to either figure out some way of fooling the stock to switch to closed loop or fault mode.
Or have a switched supply that gives around 0.3v back to the stock ECU to fool it into believing it's running at Stoich.
Problem here is the stock ECU isn't always looking for the same Air/Fuel ratio so you could set it to an equivalent voltage of a AFR of 14.7 and it'd fool the stock ECU, another time maybe the stock ECU is trying to achieve say a AFR of 13, in this case it's going to keep adding fuel till it either faults out or hits it target.
Either way it's not a built in feature and will need some extra parts and know how to fit.
I've tried this by modifying my O2 clamp and you still cannot get a good consistent tune.
If the EMU was a half decent solution i'd keep it, as over the last 7 years or so i've gotten used to it and know my way around it.
I also find it's datalogging fantastic.
Fact remains though because it's constantly fighting with the stock ECU you simply cannot get a good consistent state of tune with it.
Go for a standalone it's a LOT better solution.
