Nistune Forums

Hello. Not sure, if it's a bug of course - but every time, I upload the map into the ECU I get a number of knocks counted. The engine can be running or not, it makes no difference. The cells in the maps are also marked as knocking (if turned on). I have to reset knocks in the knock warning panel and...

Oh, that's interesting. I didn't know that.
I guess it injects 1+4 then 2+3, then 1+4 and so on and the "unused" fuel sits there and "waits" until the second injection comes and the intake vale opens.

Thank you!

Can anybody explain this logs to me? I don't understand what happens at the marked spot. Injection time dropping 1.png Injection time dropping 2.png The log shows a full throttle low to high RPM run in 2nd gear of a CA18DET with a GT2560R, 350Z MAF and 444cc injectors. After exiting the o2 closed lo...

Thanks. I managed to tune the map to match my new specs. (devide K, multiply TIM) But the questions I had are more related to how nistune works in theory than to simply get a proper result in the end. Maybe the reason is that I'm a software developer myself ;) It helps me understand how the differen...

Thanks for the quick reply! I'm not sure if this answeres all of my questions, but... I would think, that scaling the MAF sensor / K-CONST would lead to this: Stock: e.g. 1kg air / min --> 3V MAF sensor --> Load index 90. Larger MAF: 1kg air / min --> 2.5V MAF sensor --> Load index 90 (due to a scal...

Hi. I'm facing a similar problem after changing the MAF sensor. It's a CA18DET and I swapped the stock MAF sensor to the one taken from a VQ35DE (350Z). Performing the change in nistune, the K-CONST went from 183 to 504, causing my load to go off the map. I understand to reduce the Load Multiplier a...

Hi and thanks for the detailed reply! Somehow I wasn't notified about your answer :( My idle switch is working fine. The "problem" in my case simply was the idle timing setting, which I couldn't find by searching for the value (10), because 16 stands for 0, so 10 was represented by 26. Now...

Hello. I'm quite new to the whole NIStune thing, but I installed the Type1 board into my ECU by myself and got the software working fine on my Car-PC. I downloaded a ROM that's close to my specs and modified it for my setup and even did some mapping and tuning on it. The car runs better than with th...
