im using the innovate lm1 with the lsu-4 sensor. 2 weeks ago i put a brand new sensor in there, drove 100 miles to jersey. sensor was working properly and my a/f was ok. (i was in the high 13's on the highway, which isnt very lean, but not bad for my basemap). long story short, 100 miles later im back home and my a/f reads all over the place, without me making any changes to my fuel maps.

i had a similar experience last summer, my boost a/f out of nowhere went into the 9's on the wb, so i leaned out to 11's. turns out my sensor was bad and my a/f was really in the mid 13's. i have the sensor at the front of my downpipe, its about 6-7 inches from the turbine outlet. these are oem vw sensors, they shouldnt foul that fast

Interested in this subject. I have the Innovative wideband as well and never leave the wideband sensor in after tuning since I also have had a couple of sensors go bad.

Not positive, but my AEM UEGO wideband setup said to mount the sensor something like 20" or so away from the turbo as too much heat would make them go bad fast, as well as having at least a 10 degree angle from horizontal to keep water from blowing them up.

here's a pic of where it is. thats just a bad regular 4 wire in the bung, but its where the wb goes.

the heat is killing them... mount them at least 20" away from the turbine outlet

i think innovate sells a spacer that threads in between the bung and the sensor to lower the temp the sensor is subjected to. might be a good solution if you don't want to move the bung...

that wont help... if its 1000 degrees on the outside of the pipe its hotter inside, he needs to move the bung

check your ignition timing as well. Your egt's may be hotter than normal which is making your problem worse. But yeah...move your wideband further back.

good advice guys. i remember hearing that they should be like 8+ inches away. i kinda fucked up when the dp got made with the bung placement. im making a new one anyway soon when i weld my ecutout in

yeah it is probably right in the flame track. i have mine mounted by the stock o2 where the downpipe meets the exhaust, you should really move that thing.

anyone run a wideband all the time, or just when tuning.

platinum.

I have a LC-1 and it's acting the same way you described. It would jump around hella, and at decelleration it would dip into lean as high as 24+. I may have to get a new sensor too... but my sensor is located after the oilpan, on the DP @ 9 o'clock.

I would like to know this as well.

All the time here. No reason not to since the sensor is off a stock VW beetle it should last a good hundred thousand miles if you don't foul it.

Deceleration AF's should be high since fuel cut is active......think about it.....

alright well, i forgot to mention that even durring accelleration it jumps all over the place ie. 8-20.

The wideband unit itself is usually the cause of malfunctions like that. A better quality wideband controller can deal with the heat much better than the innovate, and you'll get alot more life out of your o2.

I run my wideband in my downpipe fulltime.

Been runnung the AEM UEGO and mounted about 22 inches away. No problems here.....

What would be a better quality controller that you would recommend?

I haven't had problems with my sensor going bad yet on my lm1 *crosses fingers*, but I only leave it in for tuning. It has been on many cars though and been run for a lot of miles on my own car while fine tuning things.

What controller do you suggest. It seems that a lot of people keep the plx units in their cars. Of coarse I always thought the lm1 was suppost to be better.

I've had really good luck with both the Motec PLM and the FJO. I know ALOT of people have had problems with the innovate and the aem. If you compare the prices of them, you'll see that the cheaper ones are the problematic ones. Funny how that usually works out. lol
