Anyone know if the VSS signal from the stock EF CRX cluster will work with the P72 (OBD1 GSR) ECU to activate Vtec? I'm using a '93 LS transmission, so there is a speedometer cable coming from the transmission, not VSS wires.
Are there any tricks to fool the ECU?
Also, does the ECU use the VSS for anything else?

Thanks
Ben

 

The VSS from the CRX speedo works with the P72 if anyone cares...

 

if you think about it the jdm sir crx has a vss too so it will work as long as the cable doesn't come out vtec wil come in. yes it will work, this is from experience
