ya, but those are at best estimates.
same with vac. gauges. but if you get one that monitors injector pulse width and vss signal, you have a very accurate reading.

Doesnt work on diesel engines. it's a vacuum gauge setup, and when we have any boost, it will read 0 mpg. even if im going 80 mph.

it would be really nice to have!
it is based off of computer only- on the newer engines they come with vac gauges (sometimes known as mass air flow sensors) that it can tap into.
on newer diesels the computer incorporates boost into the reading, allowing the computer to work.
there's a compatability list on the site, and says 96 fords except with diesel engine...

I found a site with guys who made them for a Geo... same idea, MUCH smaller injectors. but it had to have a computer or tablet with a program to translate the data... I just want a gauge..

Yup I saw that too.

Check this out:
Technical Information

It says its available for the Powerstroke


There is a application chart but I cant download it here at work. It is in the order/contact link. It is kinda exspensive $239 plus $30 for the buzz test option

Here's another, says ALL 96+ vehicles, but i'd still question them about the diesels, quick look but I didn't find reference to diesel on their page.

EDIT: in the tech specs is says compatible with Diesel

Maybe you could retro fit a Lie-O-Meter from the newer trucks 99.5 & up.
That's what those guys call them. Not very accurate.

I agree with 93F1505.0L .... I just use my gauges .... but I look at the EGT's and boost the lower the better.
