For you guys who have fx4s and sxt's there's a trick I learned since we don't have those on board computers that give us mpg..or stuff like that...there's this trick..goes like this:

°Get in ur truck with all doors closed
°press and hold odometer stick button..do not let go
°Turn ignition to where air con and
radio turn on only
°after u turn the ignition to that point..it should go all black on the screen
°let go of the switch button and then it should say..sweep guages
°from that point you can toggle to different settings and even turn it into a digital tachometer reading your RPMS and MPH

 

This is not a trick. It is the HEC Dealer Test Mode and is available on digital instrument clusters on many Fords starting in 1999.

It is documented in the service manual and in numerous places on the web.

Google "HEC Dealer Test Mode"

Lol damn! And here I thought I was special...anyways hey can it show u the mpg?

 

Nope, but an add-on ScanGuage II can...

Steve

 

Oh yeah I heard of them things.they're a pain to hook up..

 

this is a double post, i posted this about two months back. its useful if you dont have a tachometer in your truck, otherwise it wont do much. it can function as a digital speedometer, but its not very accurate.

 

i thought scan gauge II hooked up to the obd2 port

 

Yes. it does. What is the point you're making?

The OBD-II system keeps track of a LOT of things. The SG-II is able to pull the needed data and produce MPG calculations for display.

if it is plug and play how much of a pain could it be?

that was the point i was making... couple posts away though so i see your questioning... my bad shoulda quoted them

 

Im trying this

 

If plugging cord A into socket B is a pain, then yes, I can see why you wouldn't want one

wait....would an A cord fit in a B socket?

 

only if you have either an A-A or a B-B adapter...

 

It is not that hard, you just need an A to A cross over cable.

The A and B have different pin assignments, the physical socket is the same

 

I already forgot what were talking about....
