Hmmm ive just been on the phone to Black code and they say they can do it...not via oem software though.
find out what software please as this is new to all members on here. Throughout the world uprev tuning is used or a new aftermarket ecu is fitted.
You wont get much gains to be honest without supporting mods. Even then you probably barely break the oem figures on most cars except the later HR engined cars
Yeah i will. Basically (very basically!!) they either come to your property or to where the car is and download the data from the ecu, send it back to head office where they then download it and remap it. Its then sent back and reinstalled into the ecu. A friend had it done last week on his top end merc. The ecu on the merc has some sort of anti tamper program (as does the Z apparently), they bypassed this and updated his ecu. Took about 2 hours. I asked what difference it made and he said a few things, quicker throttle response, more low down torque, very slight improvement 0-60 and better fuel consumption. Although he said he hadnt noticed any difference on the fuel side of things as yet. Funny enough, the guy i spoke to was an ex nissan guy and knew all about the Zs. I asked about the obvious stuff ie 0-60 times and he said there would be a slight improvement but it was more aiding response through the gears, torque and low down grunt that benefitted most. Interesting. Now im no high end mechanic so im only relaying what i was told by my friend and by the technician...but it sounds interesting to me!!...so far!!
