I have been using the 2.5 version of VMSpc, with a '04 version of the ISL400 engine. I have had problems with later versions of the software, so I just stick with the old version. It works. Periodically the trip gauges will drop the fuel readings for a few seconds, but they come back quickly. The glitch does not affect the rolling MPG or the current MPG, just the trip meters (I use three) and the tank minder. But it is a minor inconvenience, not a deal buster by any means.
It has been a while, so I have forgotten the reasons I gave up on the 3.0 and 4.0 versions, and went to the old 2.5 version.
