Ls swap - How to fix tacho not working

[@giuseppeverdi1253]

Well done, man! I actually need to do this very thing. I've had the SGI-8 E for about two years but have not installed it yet. I swapped an LS2 out of an '06 GTO in to my '87 Monte Carlo SS. I actually installed the Dakota Digital ECD-100-2 to work the factory speedometer.

Thanks for watching, yeah mine sat for 6 months yet only took 1 hr to install. All the best

Hi Firebird... funny...we’re both talking gauges lol... I’ll have my LS swap video soon... it’s still winter here in Canada... but the weather is starting to cooperate. That’s a nifty little unit to get the tachometer working. I thought it would be cool to have someone with electronics experience to build a LCD style bar tachometer in place of the turbo lights on the hood. Kind of like the old C4 corvette digital tachometer... but long ways across like a ruler, plus a digital Display on the far right. Cheers

That's exactly the idea i was thinking of too how bizarre

[@vikenlink]

Firebird great minds think alike 🧐

My intellitronix tachometer reading high. Its pegged out at 8k it has a 4 6 and 8 setting. I set it to 4 . I wonder if this would help a aftermarket gadges...

[@evilswingythingy]

Perhaps it may. Mine has never missed a beat in 6 yrs

Hey, Where is that Red wire coming from the engine bay? Is that the signal output wire that will go to the gauge ?

[@timmckenney6981]

I also put an LS into a Firebird. I have the SGI 100BT I’m trying to get working with my tach. My tach has two wires coming out of it. Which one goes into the SGI 100 and where does the other one go? Any help is appreciated.

Let me check on my setup tomorrow ans will let you know asap

[@DELTRANIO99]

Nice What size LS you put in ?

[@evilswingythingy]

Ls 5.7 same as gto pontiac

[@DELTRANIO99]

@@evilswingythingy Nice ! How does it compare to the 403 lol

[@BeEasyTreeFarmer]

So I've got this unit on a LS E30 swap, original tach was to a 4 banger so I put my IN as 8 since that's input from the engine and I put OUT as 4 since the tach was for a 4 banger but my tach does nothing but will work without the Dakota digital but read incorrect. You think I should do what you did? 4 in 8 out?

[@evilswingythingy]

Yes definitely its the only way it will work. Double check your wiring as well

[@theecstasyofgold7286]

Will this work on a diesel that gets its signal from the tach post on alternator, after the alternator was swapped with a different pully size?

[@evilswingythingy]

I'm guessing it should work. Best to visit dakota digital and send them a email to be certain. They respond very fast .

[@mbrans875]

look for this one "Dakota Digital SGI-100" it shows a diesel input on the module

What is that OBD II dash unit you have installed? Where did you get it?

[@evilswingythingy]

Ebay or aliexpress aprox $30

@@evilswingythingy Is that just your cell phone on your dash? Is it getting the PID info from a OBD II dongle type unit?
