Subject: Fuel Enrichment; TT vs Autotech (or coolant vs DPR)

Does anyone have an opinion or experience as to the best approach for fuel
enrichment for the CIS-E?  
There are two approaches that I know of; first the TT version which enriches
mixture via coolant temp sensor circuit.  The second version is the Autotech
which enriches mixture via DPR current.
Thanks, Rick.
 
 
 
The TT fuel enrichment is simple and it works great, you can really feel it
from 4000 and up. The best part is that if this simple 1100 ohm/DPDT relay
circuit ever fails, it has no affect on how the car runs. It's as though it
wasn't there...
