For your standard FI engine, yes, you need an EFIE (electronic fuel injector enhancer). Google it and you can find stores who sell them. They are relatively easy to install, requiring a wire to be spliced into the O2 sensor wire.
Ok and thanks. The diesel has no computer of any kind ( thank God) it is totally old school diesel. The only two things that electrical does on the older diesel engines is to open or close the fuel solenoid when you want to start or stop the engine and turn the starter. Wouldn't it be nice if things were so simple today.
On a over the road truck that runs 100-180,000 miles a year I can see where this would be great . We only run 3-4000 miles a year and on the van even less than that. so I guess I need to kick it around some. I really like the idea and may go with it just to say I have one. If I can get a 25% MPG increase in the van I would be a happy feller.
Thanks again for your help.
