what one is the one to use????

easy to hook up?
price?

 

You want the SGI-5.

It's simple as hell to wire up. Just run the two wires from the VSS to the box, and then tap into the instrument cluster wiring for the +12V and Ground signals.

 

Has anyone ever put one of these in for a T56 and a 3.27 9 bolt rear? (stock tire size) If so, would you post the switch settings you used - it would sure simplify matters for me!

Thanks!

 

Lee...

I think the best thing to do would be to calculate your MPH for a given RPM over a large range (say 1000RPM to 5000RPM) in first gear, and then use a scan tool on the ECM to verify that they're correct. This isn't an auto tranny; there's no guesswork involved and you can calculate the MPH directly from the RPM. Start out with the 1.0 setting and go from there.

Oh yeah, use the RPM information from the scan tool as well... don't trust the tachometer. The best way to do it is probably on the jack stands with the cruise control engaged

Once you have the ECM reading correctly, recalibrate your speedometer to match. At this point the SGI box is functioning properly, so don't fiddle with any of the switches

where does the cable hook up too?

 

i know one of you know

 

Where does what cable hook up to?

 

speedo cable

 

It must go to that electric speed sensor, did you check on that site I posted up there??
I have a spedo issue to, thats my post on how do you convert gear to electric

 

Uhhhh... you can't use a speedometer cable with the T56. It's all electrical. I suppose you could get a cable-X box, but why?

 

cuz i dont got the money now to set up auto meter guages

 

Unfortunately, you either have to get a cable X box (which I understand is ~$300) or the dakota digital box (~$150 I think) and some sort of electronic speedometer, if you're going to switch to a T56. If you can't afford either, you'll have to just base your speed on the tach until you can.

 

How easy is it to just put a auto meter speedo in there?

 

I couldn't tell you. I swapped to a factory electronic setup.
