4stroker Posted September 17, 2007 Report Share Posted September 17, 2007 hey guys i hava a car tuning friend who owns an "Innovate" wide band 02 meter i want to use the device on my banshee for tuning/research purposes i would like to hear from guys with experience in this on where to put the sensor 1. in the header about 3 inches after the exhaust port 2. at the end of the expansion chamber just before the stingers 3. right at the end of the silencers which location would give the most accurate/useful results... thanks, mark Quote Link to comment Share on other sites More sharing options...
Coupelx Posted September 17, 2007 Report Share Posted September 17, 2007 the 2 stroke oil will kill the sensor along with leaded gas if you run leaded race fuel. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 17, 2007 Report Share Posted September 17, 2007 the 2 stroke oil will kill the sensor along with leaded gas if you run leaded race fuel. He'll be able to get enough runs in to tune, it...though. It'll kill it with prolonged exposure to leaded gas and premix...though, you are correct. PM ojcool...he's done a lot of wideband sensor testing... Quote Link to comment Share on other sites More sharing options...
Coupelx Posted September 17, 2007 Report Share Posted September 17, 2007 (edited) i forgot to add that i think it would be best at the end of the expansion chambers. the sensors also do not like alot of heat unless you build a heat sink for them. this may have some insight for you http://www.wbo2.com/lsu/position.htm Edited September 17, 2007 by Coupelx Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted September 17, 2007 Report Share Posted September 17, 2007 I would use a pyrometer. Quote Link to comment Share on other sites More sharing options...

TurboBanshee420 Posted September 23, 2007 Report Share Posted September 23, 2007 (edited) If you mount it next to the port the readings will be WAY OFF! Since 2 strokes let out a ton of unburned fuel that eventually gets sucked back in. Th O2 will see all of it and not give you the right reading. An o2 only reads the amount of oxygen in the exhaust not fuel. If you want an accurate mounting position the put it right before the muffler and also mount it on the above the 3-9 o'clock position so the sensor doesn't have any water or condensation sit inside of it while it tries to heat up during "turn on" If your going to get an innovate WB, then get the LC-1 controller with the XW-1 analog gauge package. It will be well worth it if you want to watch where it is running all the time. Pricey though.... You might want to think about one of those pyro gauges from ebay.... http://cgi.ebay.com/ebaymotors/Digatron-AT...sspagenameZWDVW These things are cheap and work just as good. The innovate system I have cost me around $350 for the WB & controller... The XM-1 standalone gauge is another $300 Edited September 23, 2007 by TurboBanshee420 Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted September 23, 2007 Report Share Posted September 23, 2007 yeah, you got to get the jetting close and place the probe within 6" of the piston and out of the wetline. Quote Link to comment Share on other sites More sharing options...
NotsafeFWD Posted September 23, 2007 Report Share Posted September 23, 2007 According from my experiences from Wide Band O2s, you wanna place the probe about 2 feet from your main source of heat. In my turbo Talons I'd always place them in the test pipes, and that always gave me an good reading. However, remember that the closer you get to your exhaust port the better, but as stated before, with a 2 smoke you'll have a reverb of exhaust charge and fuel, so ofcourse after the expansion chamber is your best bet. I'm not 100% on the thresholds you'll want for tuning, whether it falls into the same category as a 4 stroke natural aspirated engine(14.7 being completely stoich and ideal). My 2c into this topic.

RZBansheeMan Posted September 23, 2007 Report Share Posted September 23, 2007 (edited) You almost have to treat the expansion chamber as part of the exhaust port in a fuel injected type scenario using 02 sensors. Treating the stinger tube as a "header" tube rather than a tail pipe, therefore mounting the 02 in the stinger tube either midway or towards the silencer........just my $ .99 worth...... :geek: Edited September 23, 2007 by RZBansheeMan Quote Link to comment Share on other sites More sharing options...
