How to: Install DIC in gmt400 overhead console

How off is it would you say?

I average 350 miles to about 22 gals. Which is right at 16 mpg. The highest the display reads is 15.3 on the avg mpg.

Also the range is almost 100 miles off like I said earlier....

I assume the instant mpg feature reads low by almost 1 mpg also but I have no way too check that.

Would you say the range goes down like it should? Like will it let me know its getting close to 0?

The distance goes down as the fuel level in the tank drops. S-Series have 19 gal tanks, so it is constantly reading low. After you get under 40 or 35 miles it just reads low. When it says that I still have over 100 miles left. There is no way that I know of to recalibrate it for those additional 7 gals...

I wouldn't rely on it to keep you from running out of gas. I still use my trip meter every fill up.

My range works good, and mileage is very close, if not right on.. which is unfortuinately not quite 13mpg.
I'm wondering if anyone has the same setup/problem as me. I have a switch to turn off my abs/overdrive (hooked to the fuse in cab) I use this alot when towing lighter things, Problem is it freezes the data on my display when I do this?
Would this be the serial data or something with where my vss is hooked up?

I really need to get around to doing this on my 98, got everything sitting there to do it. Paul, any chance you could get ahold of one that is just temp/compass and a temp sensor for my '92?

Ok well after thinking about it I think I'd rather just have the temp/compass if the DIC is going to be off anyway. I wouldn't think any VSS input is needed, and I'd be fine with it being full illumination at all times, can't be too bright right?
