 signal itself and then sends out the conditioned 4KPM to the cruise and 
 cluster. These are the speed density systems. If you're using this setup, 
get 
 a converter from www.JTR.com to change from 4KPM to the ac output the ecm is 
 looking for. They run about $45. >>

Ok, now I'm confused. Are you saying that the 95 TBI ECM uses the exact same 
4KPM sensor as the speed density TPI or not. I understand the TPI uses a 4KPM 
magnetic sensor which puts out an a/c signal. I've bought those from JTR 
before.

Oh, and thanks for the help. One of my future plans is to tune VE and spark 
tables with this ECM # and then transfer the VE and spark tables into a 7747 
and have them work the same. I plan to build a conversion harness for this 
purpose. JW
