Hey,
I have nistune in my r32 with rb22 (forged and n1 stuff) and new hks 2530, gtr 440cc's, walbro and a z32. the nistune'd ecu i have was from a car in qld or nsw with rb20 and a hks 2530, 440s, z32 and a 040.
Question is, if i take it to my workshop and plug it in to any old nistune software, can i adjust the current map or do i have to start from scratch, seeing as the tune was made on someone elses computer/licence etc etc.
Thanks
