I read somewhere to disconnect the battery for a day because that would reset the electronics. But pressing the hr and min buttons next to the clock does nothing. No lights and nothing happens when I press on any buttons - except the clock runs continually like when you press the hr button to set the time. Problem 2: The aircon controller unit has stopped working. So if anybody could send me such a file that would be much appreciated! However, I would like to compare it to a similar data file from a Skyline which runs well because there is nothing in my recording that stands out (to me) as obviously faulty. I finally got the correct adapter and the Nissan DataScan 1 software and have recorded ~5min of driving data. It only does that once after each revving. When I rev the engine to 3-4000rpm and let it come back down to idle, it comes down to ~800rpm ok, but then does a little bump up on its own to ~1200rpm before settling back down to idle.
Problem 1: It runs ok, but uses a lot of fuel (~280-290km/tank) and the exhaust smells like an old car in the 1970s when I start it in the garage. I'm new to this forum and I'm trying to solve a couple of problems on the Skyline which I inherited.
