[Link V4 Misfire or Hickup in my tune]

I have always had a hickup in my tune whenever I hit about 3400-3600 rpm. It has always been there and never gone away and is consistant. Can't figure it out. Only thing I noticed is that my Link ignitor is not physically grounded, but the ground wire attatched to it is grounded. I have a Lem V4 with a wire in patch so I did not cut my stock harness. Not sure if it is wiring or the ecu itself. Please advise Thanks, Ron

[Lem V4 Windows Vista]

I have the white and green box Lem and I am unable to get it to work with windows vista. Is there something that can be done so I can get it to work. Thanks, Ron

[Link Lem]

I am not quite sure what version LInk I have but I know it is the version that could be upgraded to the link plus. Anyhow, my Pclink was on my old lap top with all my tunes whick I do not have access to anylonger and my car has been sitting for a few years since running the ecu. My question is will I be able to run the latest version of the Pclink, start the car in live mode and be able to retreive the last map in the ecu and save it for a reference to tune from? Thanks Ron
