I wanted to update this thread because It's irritating when you get a story going and it is nevery finished. Seems to happen a lot on these forums. I finally go my car fixed after weeks of frustration. There were a lot of speculation from members regarding what might be the issue, but no one hit it on the head. Originally I did not have the uprev cable when I bought the car. I took the car to a tuner, (not Uprev) who spent a lot of time scratching his head, but could not get into the tune because they were not uprev certified. There are only 2 such tuners in WA. The local guy fixed a few minor things for me but most of their time was labor chasing things that did not make sense. After replacing an 02 sensor fixing some wires and an oil leak, they said they couldn't do any more for me because they could not get into the tune. So I stopped driving the car in fear of damaging it. I did eventually get the original uprev cable from the original owner and was excited to get the car back down to the shop. Once I did I was told that the cable was not married to the car and that they could still not get into the tune ? Dang ! They said, as far as they could tell, the tune on the ECU was the standard Z tune. So I make an appointment with the last shop that tuned the car in Seattle. The tuner figures out that someone flashed the ECU back to stock, because his tune or any other tune was not there. When I bought the car, the previous owner had taken the car to Nissan for an ABS issue. Nissan must have update the ECU and wiped out the tune. The Tuner is Seattle still had the Previous Tune on his computer, so he reflashed the ECU back to the last Dyno. He gave me the ROM file and sold me another license. I drove away in a half hour and the car runs like a charm !!!! Story ended....... The tuner said that dealers flash ECU's all the time without thinking to tuned cars. I thought how stupid can they be ? Apparently pretty stupid. Anyway, I'm happy now and on my way to the next project. While the car was layed up I install all new stereo equipment. Looking for an oil cooler now. GTM 34 row is pretty expensive. I'll probably do a little research to see if I can find a quallity oil cooler at a lower price. Thanks for all the comments and suggestions.
