Andy,

Can the 4Di be used without the O2 sensor?  (I realize tuning becomes more 
critical.)  Due to water-cooled exhaust system my marine application makes 
implementation of an O2 sensor difficult.  (One possibility I thought of is 
to tap into the currently blanked-off EGR port and run a seperate mini 
exhaust, but this raises questions of its own, such as how much flow would 
be required to give accurate feedback, where to discharge this exhaust, 
etc.  So for now no O2 sensor is my goal.)

Holley is advertising a marine 4Di which should go on sale in a couple of 
months.  I've spoke with Holley tech twice.  One rep said that the marine 
4Di must use the O2 sensor and the other one said that it wasn't necessary. 
 Sadly typical for Holley.

Thanks,

Mike Jones

I have 2 4Di manuals.  One is not released yet (i feel so special...).
If you would like a copy of that an the software, gimme a jingle.  The
4Di uses a heated O2 sensor, by the way.  I drive mine to work and all
over the place all the time, so i know it works!
