Any update on the 90 extender changing o2 readings other than slower

ezstriper

did not help...killed #3 the design of the headers is a killer...

Did it change the readings any

I've used the Innovate 90 degree heat shield for the wideband and it did not change the readings. I was worried it would but it did not.

Hmmm, I guess my plan on putting O2 bungs in the divorced collectors of my Lightnings might not be such a great idea.

I would not waste the $$ at this point if they are the silent choice ones...

EZ, I have both. They came with the divorced collectors that attach with the short 6 inch diameter hose. They have an internal pipe that extends the point of water entry about 8 inches. I was thinking about using these to get my readings and dial in my tune, and then switch to the silent choice ones later without the wideband O2. I was planning to just use the wideband to dial in my setup initially. After that it should be pretty static. Not planning on any changes after that, and even if I did, I would just switch collectors again while I do the tune. Think this would work?

if you can get the water to dump about 12" from the 02 you might have a chance from what I've been told, in our deal we could get it to live at slow speeds, cruising, etc, but when did a WOT test and backed down(not quick either) thats when killed it..I would do the 90 extension like we tried for extra insurance...

EZ, have you always run yours with switchable diverters in the collectors, or were you running it with the divorced collectors as I described? Were you running any type of muffled tip? I would think that would also be a factor in back-pressure contaminating the sensor.

ezstriper

we only ran the silent choice deal..all we have, and always in the open position, no mufflers, issue is the water is only a couple inches back from 02 and not much we can do about it...even called lightning and asked...
