TPS and RPM

[peter paul fenske]

Howday..

Jeesh prob enough of the gang has mentioned this
but there were systems using this.

HOlley used this in their analog box and mercedies tried it.
IT was called alpha N fueling. To get it really right you
have to really figure out the airflow vs tps. Mercedies used
a multi trac tps to do this.

Oh course you need coolant temp compensation.

I am getting a cct together for you guys.
will post it when ready.

Oh yes if you use a gm 1 bar map you get 1.5V at idle typically
and about 4.9V at wot. 

The TL494 gives 1% DC at 3.5V and 100 % at 1 V input
