OMG found it lol

Depending on year model , I believe it is either R109, R73 or R2 ... maybe something else... somebody can chime on it.

 

Tach finally working yey

 

Gratz man! Feels good to conquer the final details huh?

 

Thanks again for your help man.. I have airbag light, and speedo left on my cluster. Will tackle them later.

Here's what I did

 

I received my SGI-5 and finally had time to calibrate it. It is now working with my GM sensor, I have my cellphone GPS and matched it with my speedo and it is accurate.

Thanks for the help turbodremz, stockhatch and ali

 

hate to bring an old thread back but I am working on using an ar5 trans in my 91 cressida and was looking for an easy solution for using the speed sensor on the trans to drive my speedometer, came across this: https://sirhclabs.com/product/vr-to-hall-sensor-converter/ not sure if you'd be able to just wire it in and it would convert the signal to what is needed but that would be awesome and its really cheap at $16... I wrote the company to ask so I'll let you know what I find out when I find it out. Heck its cheap enough to just buy one and try it out and if it doesn't work i'm not out much.

 

Is your 91 Cressida a cable driven speedo? If not you should just be able to bolt a w58 speed sensor on there. I am doing the same swap and ill report back .

 

It's not a cable driven speedo but the speed sensor is gear driven off the output shaft on the w58, the AR5 trans I'm using doesn't have a gear off the output shaft to be able to just swap the speed sensor off the w58 to the AR5. looks like the Dakota box may be my only option, I wrote the guys I linked to and their signal converter will indeed convert to a square wave output there is no way to calibrate it to give the correct speedo readout.

 

found another device that a lot of motorcycle guys use that should work, emailed the company and they confirmed it should indeed work. I like that its super small and easy to program.

well damn, it is a cable driven speedo... now to figure out a speedo I can fit in my cluster and how to get signal from ar5 to it

 

Sorry for resurrecting this old thread, but I am looking for some clarification.
I am doing a Chevy twin turbo & T56 trans swap into my 97' SC400 and leaving the SC's ecm intact, I will just remove the 1UZ's harness. Now, the Dakota Digital's SGI-5 is now discontinued, the newer version, the SGI-100BT interface unit takes care of both the speedo and tach calibration, one same unit for both. If I do get the SGI-100BT unit and hook it up to my 2-wire T56 sensor and hook it up to the SC's IK1 pin #7 I should be able to calibrate my speedo correct?
Questions:Will the ABS work correctly???
Will the airbags deploy if needed(crash)?
Another questions regarding the tach calibration; do I need to do the R2 resistor modification??
And to what pin or terminal does the DD SGI-100BT output connects to in my SC's cluster???
Thanks!!!!
