B16a1 0bd, pw0 ecu.

Ok, I was told that my vtec wont enguage without the electronic VSS signal coming from the tranny to the ECU.

But i have a cable driven Cluster. My question is to you, how do i make this work?
Do i need a whole new cluster to wire it up or can i someone hook it up so i dont have to use the cable on my cluster to the tranny.

Thanks in advance

And yes i searched

 

also if i switch to a pr3, i wont need the electronical vss i could just use my cable correct?

 

hmm nobody running a pw0 ecu...great.

 

This ECU reads pulses from the VSS electronic sensor.

While the original motor and cluster used a cable, with no electronic signal to the ecu.

I dont have the money/time to change clusters. However my one friend told me that i could bypass the whole cluster speedo cable imput. And i could soldier a wire on the back of the cluster and just send the VSS signal to the Cluster.
He said something about following the output of the speedometer cable on the electronical board. The cluster just converts the speed of the cable to a digital reading so i dont think it would be a problem. But im unsure where to soldier the wire from the electronic VSS.

Any help would be greatly appreciated.

 

continue running the same cluster you have. use the cable driven vss. the ecu recieves the signal from the cluster rather than the sensor itself if you use it this way. ecu code has nothing to do with it. if you convert to si-r cluster you have to convert to electronic vss because the signal originates from the sensor itself rather than the sender in the cluster.

sorry if it seems like gibberish...typing it as i think of how to phrase it.

cliff notes: use cable vss and cluster-it will work.

The ECU doesn't look for the signal from the VSS. It looks for the signal from the cluster and the speedo on the cluster. When your speedo isn't working, then you know you won't have VTEC.
