What you did to the tach for the rpms to work.. I did an ls swap on mine but I couldn't get the rpm to work like that mine stays in the 500s and barely moves.. would you help me with that
Took over a year but that was working at a very casual pace. I have the whole swap documented here: www.clublexus.com/forums/performance/672455-2006-is250-ls1-swap.html
