[T3] Bad day at the (FI) office

Below 100 ohms, your not enriching the mixture anymore, so there shouldnt be any differences below that, if you want shunt it down to 50 with a shunt resistor HOT.  This will also enrichen your warmup so it may not start cold and track properly.  You need to have NO enrichment by this when the engine is hot.

You need to keep adjusting things because the T3 is an open loop system, it cant compensate for changes in the gas and your using NYS gas, it keeps changing, NYC gas might be worse yet... winter blend and summer blend are vastly different...  but Ill bet if you get everything right, in the middle of where it should be that your adjusting things less, the later systems adapted better to this.
