Alright I got a 92 SE-R I just got finished not to long ago swapping in a DET (factory turbo'd SR20DET). Well I was trying to use the stock USDM SE-R ECU but it wasnt working to well so I swapped in the JDM DET ECU. Needles to say it runs great other than it has a speed limiter set at about 115 mph. There is a way that you can either cut a wire going to one of the pins on the ECU or you can get these expensive little boxes that you hook up inline somehow with some wires I dont know. So I know that there is a few people in here that have messed with the Nissans some and may know the trick. I tried to get the info off of another board but I didnt quit get it. TIA

 

Wolf Technologes or Haltech would greatly benifit you.
