I have been running my NIStune for 10 months now, and love it. I still tinker with the tune now and then, and usually make slight improvements. I know that Nico wont let us attach a .bin file, so we will have to send them through email.
I am running a S13 blacktop SR20 with 550cc injectors, N60 maf, and a FP BIG28 turbo. The tune that I wanted to attach works great for me. It idles strong and the air fuel ratio is great at cruising (14.6 - 14.9) and rocks solid under full boost (11.8 AFR) which is 19 lbs. Remember, I do live in Florida so we have 93 octane (sweet). So if you are stuck with 91 octane, you my want to pull the timing down just a hair.
Email me
[email protected] for the bin file, I hope this helps someone get started, and I hope this thread will grow.
