I think I'm running an early 0.10.x then cause I couldn't get my techedge wideband to work with the newer one.. but I'm satisfied with it probably being a glitch in the software. Will have to troubleshoot somewhere else. It didn't sound very logical that the ECU wasn't reading battery voltage, but a...

I sold my old engine (340rwhp CA18DET) to a friend, and he's having some running problems with it, and the only thing I can find so far is that I can't log battery voltage in Nistune. I'm pretty sure I could see that when the engine was in my car. The question really is if this is a bug, or if it's ...

my techedge wideband only shows "9". It says it's connected, and recieving data, but does not move from "9". Worked fine until I updated to 0.10.x

thought I'd post back since I've solved the problems. Latency I've left at 950us, simply because the car runs better there.. which is funny, cause it's about half way between the info I found online (one said 630us or something, and the other said 1350us..). The cold idle problem was partly due to t...

I think I've sorted it out. Will have to wait until tomorrow to see if she idles better, but my money is on it being fixed :) I remembered I noticed the CAS was quite a bit from being centred in the adjustments, and thought I'd double check the timing adjustment procedure in the manual. Stupid me as...

I'm starting to think more and more that it's timing related.. can anyone confirm what cold idle timing should be? The car feels very jerky when driving on low speed when it's cold. Runs fine when water temp reaches 40-45 degrees. AFR's are around 10-11 on first startup, so it's getting too much fue...

if the car runs ok at 950us (which means it's potentially injecting fuel before the valve has opened sufficiently), you reckon it'll be better to just leave it there? Will it affect fuel consumption? I don't think it will, but then again, why does AFR's change when changing latency? I still have 2)....

been fiddling around with it a little now, and it seems that if I set latency to around 1150-1200, the car idles better. The popping/banging more or less goes away. But when I do, I get richer mixture on idle. So I then tweak the K konstant to get ~14.7 again, and go for a drive. I then get 19-22 af...

alright, thanks for that. Will let the latency be then. could try increasing the gap on the plugs a little bit. I had the exact same plugs on my 400hp CA18 and had no popping problems. Did have a tiny bit more electrode gap on those though. Maybe 0.6 is insufficient for a clean burn on idle. I've ac...

oh yeah, nistune triggers IDLE SW when throttle is closed

Hi! I've successfully transplanted a series 1 RB25 into my s13, using Nistune type2 in a Z32 ECU. I actually haven't had any major problems with it, but there are two things I want to ask about. Firstly, I have RC Engineering SH4-750cc injectors, and according to a forumpost I found when googling fo...

alright. Then most likely I'll keep the license for myself, cause he can't tune anyway. I'll have to help him if there's any problem. But how does nistune keep track of what computer it's on? My current license, I bought "used" with my first type 2 board, and it's not under my name. Can yo...

sorry for hijacking the thread, but I think my question is relevant to the topic. I have a CA18DET S13 with a Nistune-powered ECU. I've now sold the engine to a guy I know, and I'm also selling him my laptop in case he needs to tweak the tune, cause I don't need it anyway (have a newer one). I'm goi...

I did not know there was yet another one Haven't involved myself much in Nistune since last year in July or something.

Let me revise the question then : If I install the new nistune software version, do I need to adjust my fuel-map?

do I need to re-tune the fuelmap if I install this address file?
