Long story but working 100 hour weeks in addition to starting my own business on the side, so time to do project on my own went to the wayside, so the v8 swap went into the shop and I told them I wasn't in much or a hurry. 1997 v90 has a 6.0 LY6, 4l60e trans installed and (mostly) running absent of some tuning issues I'm waiting until the end to work out.
Short story: Speedo has worked fine from the get-go, but shop is really on the struggle-bus getting water temp and tach gauges wired and working. They apparently have the correct sending unit to tap into the v8's head that should be able to control the water temp gauge. I have also given them a Dakota Digital converter box that I've confirmed is able to control the tach needed with the internal calibration signal the box sends. These should be straight forward to get wired up at this point right?
After weeks and weeks of no progress, I'm told today by the owner that they think the dash needs the original volvo computer to process the signals going to the dash. The original computer (ECU) was obviously removed and replaced with the GM version. They are requesting that I bring the volvo ECU back in for them to test to try and get signal to the gauges. I really don't feel this is accurate as the dash only needs some voltage to control the gauge needles and all that is needed is finding the correct resistance/voltage for all to work. Right?
Does anyone have any experience with this so I can redirect them?
