Thanks Matt. Ok. So I was right in my assumption that I should just get things right according to wideband, and not to be concerned with Estimated A/F Ratio. And I tried the input tracer today on the way to work. Pretty cool. Seems like it is more useful for very specific, short pulls though. My dri...

So, i'm in the process of tuning my KA-T. I have it running fairly smoothly, to be honest, but I feel like I am still not quite grasping a lot of things, and feel like it could be running a lot MORE smoothly, despite my already somewhat successful basic tune. For instance, on the fuel map, there's t...

Out of curiosity, should I have started this whole process with the stock MT bin file like I did, or gotten a pre-made bin much closer to my needs for my setup? KA-T forum hosts bins and some users have suggested getting one close to my setup and adjusting the settings to fit my needs. I downloaded ...

Ok. So here's where I am at now. I've set my latency to 795uS @ 43.5 psi (fuel pressure). At this point, that should never be changed if I am understanding things correctly. I've adjusted my k constant and gotten it to idle, when up to temp, at roughly 14.7 w/ o2 sensing ON. It fluctuates between ~1...

Injection Multiplier is the k constant, correct? If so, i've tried adjusting that as well. I was, however, tuning with O2 sensing OFF, so that could have something to do with it. What are self learn trims and how do I clear them? What is dead time? I'm running Injector Dynamics 725cc injectors curre...

So, as the title suggests, i'm new to nistune and tuning in general. I need to get my car to the dyno to have it professionally tuned, but it's roughly a 2 hour trip. So, first, here's my setup. -1992 240sx FB. -Stock Bottom/Top end KA. Rebuilt ~4000 miles ago. -Injector Dynamics 725cc top feed inje...
