mercury3545 Posted January 7, 2010 Share Posted January 7, 2010 I will be going opensource in the next 2 weeks and I keep reading about needing a wideband o2 sensor. Do you HAVE to have one to get a safe tune? Link to comment Share on other sites More sharing options...
SubyShop.com Posted January 7, 2010 Share Posted January 7, 2010 If you run modified open loop fueling, it's needed. If you run stock fueling (which is very rich), then you can get away without one. You can definitely get more performance and a better quality tune with a wideband o2. Your tuner will be able to do more for you with accurate AFR data.-Franz Link to comment Share on other sites More sharing options...
Spec B Posted January 7, 2010 Share Posted January 7, 2010 And if you have any type of aftermarket intake...I would strongly suggest you get a WB02. It is not needed..but you are likely going to run lean. I am not sure it will be dangerously lean, but the not knowing is not worth the risk imo. With a stock airbox, I think you will be fine without a WB02. Link to comment Share on other sites More sharing options...
mercury3545 Posted January 7, 2010 Author Share Posted January 7, 2010 I will be using the stock airbox with a panel filter. Also I will just be tuning myself for the time being Link to comment Share on other sites More sharing options...
yamie700 Posted January 7, 2010 Share Posted January 7, 2010 If you are going to learn to tune yourself then just get a wideband. The money you spend on the wideband will be a lot cheaper than replacing parts if you push it a bit too lean. (and you might push to lean without even knowing it, I've heard from several tuners the stock intake is not scaled perfect to begin with) Link to comment Share on other sites More sharing options...

Boostin1657615274 Posted January 8, 2010 Share Posted January 8, 2010 The stock wideband is fine if you know what you're doing. I've had no trouble tuning with the stock one. But in this case, since you are new to tuning, you may be better off with an aftermarket unit. On the search for a new DD... Link to comment Share on other sites More sharing options...
mercury3545 Posted January 8, 2010 Author Share Posted January 8, 2010 Thanks for the help guys. Ive been looking around at these sensors and they are expensive. Anyone know a good place to get one? Link to comment Share on other sites More sharing options...
yamie700 Posted January 9, 2010 Share Posted January 9, 2010 I've had the Innovate LC-1 for a few years now. Permanently mounted in the bellmouth of my Cobb DP. I don't have a gauge with mine, but don't really need one as it works with Romraider. I can't remember where I bought mine but a quick search shows Import Image has good pricing, and they are a vendor on this forum http://www.importimageracing.com/p/Innovate-LC-1-Complete-Wideband-kit.html Link to comment Share on other sites More sharing options...

Probably the cheapest one ive seen. Now you said its mounted in your bellmouth, did you have to drill a hole in it or was it already there? Im getting the ERZ downpipe and i cant tell if it has a bung in the bellmouth or not. Link to comment Share on other sites More sharing options...
yamie700 Posted January 9, 2010 Share Posted January 9, 2010 ^ The cobb DP came with a bung already in the bellmouth. The LC-1 I got came with a bung (and plug) that can be welded on to any pipe though. Link to comment Share on other sites More sharing options...

The ERZ DP's have the O2 bung in the bell mouth so you're good to go. http://www.ERZperformance.com/product_p/103erzcatted.htm Link to comment Share on other sites More sharing options...

yamie700 Posted January 13, 2010 Share Posted January 13, 2010 ^ I think he meant you need the WB02 to scale the MAF in open loop. Link to comment Share on other sites More sharing options...
Spec B Posted January 14, 2010 Share Posted January 14, 2010 ^Correct. There is no way to accurately scale the highend of the maf without a WB02. Link to comment Share on other sites More sharing options...
