BTW... should I monitor AFR from the CAN bus data, or should I get an aftermarket gauge and sensor? If I can rely on the CAN bus data, then it'll save a lot of wiring work. I may get a digital multi gauge with ODB2 input.

Get a wideband bro, there actually really easy to wire.
My wideband has help me diagnose 99% of my problems. Also, test your vacuum, maybe you have a leak somewhere.

Yea, hopefully I can get a hold a smoke machine. I'll get it done after maintenance work.

Do any of the 370z even have factory widebands? I remember a couple years of the 350z did for a minute, but then they ditched it.
If the factory o2 sensors are not widebands, the A/F reading anywhere about a half point away from stoich is worthless data. My 2009 uses standard narrowband o2s. |

I'll have the exhaust manifolds checked the next time the car gets on a lift. I remembered this being discussed at one time, and I thought that's what people concluded - that the cars come stock with widebands. I was just curious to see the wide band sensor parameters in Cipher. If that's the case, then I'll consider getting a sensor makeover at some point to go with the digital multi gauges from Zada Tech. Phew... gonna be pricey.

You can do that but I'd probably look for a single readout that will read both gauges. With the LC-1/2 you would have to run a second gauge. Most people just monitor one bank. I recommend bank 1 (passenger side) because it seems to run slightly leaner than bank 2. If you don't have the bung in either the downpipe or lead pipe just have a bung welded into the lead pipe of the FI exhaust. A muffler shop should be able to do that pretty quickly at a low cost.
Chuck - I can't recall off the top of my head, but where's your AFR O2 sensor located? Edit - Innovate makes a single gauge dual wideband but I can't seem to find it any place but eBay for instock purchase so it might be discontinued. http://www.innovatemotorsports.com/products/dlg1.php This is the one I run LC-1 with the DB gauge http://www.innovatemotorsports.com/products/db.php Last edited by jwick; 04-15-2015 at 09:00 AM. |
