Z31 Ep 26 Connecting Wideband to Nistune using DLP A/D converter

[@fernandopinto9445]

That looks like a pain for wideband

[@Filthy_Goblin_44]

So in the beginning you tied the narrow band wire into the engine harness stock o2 sensor plug. Is that all you need to get the fuel trims to log or did you have to actually have your stock o2 sensor plugged in? Also are you running a o2 sensor currently with nistune. Thanks. It took me a few time of watching to understand but I think I'm beginning to get the idea for this

[@samwashere1392]

Ya sorry, not the best at making clear concise videos 😅 but yes I just have narrowband signal wire from my wideband controller going to the plug in the engine harness where the stock O2 would plug in. I do not have a stock O2 sensor. Just the wideband sensor with controller. The controller has 2 outputs 0-1v for narrow band and 0-5v for wideband. So that one narrowband out put going to the stock O2 plug is all you need for your ecu to be able to read and trim the fuel.

@@samwashere1392 no way man your z31 videos have been the most thorough out of all of them

Hey man, nice job. I am in the process of doing a NA2T build myself. I have been posting videos, and your videos just recently started pooping up as suggestions for me. I hope I can get mine running in the next couple months.

[@samwashere1392]

Nice! Good luck with your build! Are you going straight na2t with just a turbo ecu and injectors or do you have different engine management?

@@samwashere1392 I am planning on using Nistune, but haven't gotten that far yet. I am horrible at planning ahead. I am just taking it one step at a time.

@@rrh5000 haha that pretty much what I did. Order a bunch of parts..wait…when they arrive find out there’s something better…order that ..wait…lol

[@ulyssesdacop]

How does it work for daily use, do you have to have the computer there and connected or can you plug the converter usb into the ecu somehow?

[@samwashere1392]

It’s just for tuning and data logging

[@ulyssesdacop]

And did the narrowband signal you connect work permanently for the stock o2 sensor?

[@samwashere1392]

Yes narrow band works permanently
