Ls1 conversion wiring help needed

[vp304]

Yeh I knew about the devide 5 bit
Il get it sorted out in the tune and tell u guys how I go
Thanks for all your help

Im back from the dead hehe

Ok so i changed the way i had this all wired and need you guys experience on it.

So now when the signal comes up from the 700r speedo sender instead of going to the cluster i cut the wire and ran it through the converter box then to the ls1 ecu

The output wire of the ls1 ecu red connector pin 50 i think it was i hooked this up to the signal wire that goes to the cluster.

Now with the car wheels up in the ground and the car in drive i know the speedo at idle in drive would read around 40kph or so.

When i tested mine out it shot up to around 160 180 kph lol

I can get my mate around to adjust the ppk etc settings on the ls1 ecu.

What i want to know before i get him to come down out of his way is
Will the vp dash cluster be happy with the vss signal the ls1 ecu outputs to run the vp cluster speedo ?

can't answer that as to weather the vp will like the signal or not, but why didn't you just leave the original signal going to the cluster un changed and then T it off to the converter box ?

Dakota digital do a great unit.
Will accept square or sine wave input. 2 outputs can be both same or different outputs both with different correction.
You could have speed sender straight to this box. The square out to the vp dash and sine out to the ls ecu.
And have pulse correction on both outputs.

Dylan is it the sgi 5

if so i have one lying around already.

Holden202t the un changed signal to the cluster was working but is still 10kph out even after i changed the speedo gear on the gearbox. Due to diff gears

you can make the stock speedo adjustable to account for diff gears just involves removing 1 resistor and replacing with a variable resistor enter this site into the way back internet archive has speedo section showing how to modify the speedo unit http://members.ozemail.com.au/~brettsue ... /index.htm

Thanks for the link delowizzid i think i saved this page years ago but it come up now on the way back machine.

Im just trying to keep it all as basic as possibile at the moment less things to go wrong.

Dylan i looked at the sgi 5 manual and my head boggled a little lol. Dont know how i got it to work last time i used it but yeh lol

that modification only alters the needle position. the odometer will remain incorrect

Sounds like it. Very powerfull piece of gear.
