I dont think it even references the speedo signal, as I've driven around with a broken speedo cable and had no PS issues.
can we get some confirmation on that? any other ideas on how I can make my steering firm again while at the same time retaining an appropriate amount of power steering? At this stage the SW20 GEN3 body fitted with the '97 SS3 celica engine, gearbox and ECU is causing me quite a bit of grief. Everything is running but there is power loss experienced in lower revs and, shitty unsmooth gear shifting (no crunching, just not fluid motion like it used to be) and the painful loose steering feel which compromises the handling......
