My sensors look more like the STFT than a normal 02. However they're "oscillating" at a normal amount...just that the "swing" isn't what it should be. I'm looking at the STFT base, correction and...

I ran the test that joecar indicated and I found I was only getting ~7 volts at the sensor! I cleaned one ground and I removed the splice pack for the other and soldered everything together onto an...
This is a real old thread but I found it useful anyway. I noticed "oil contamination" as one of the listed potential reasons why an 02 can become fouled. My car definitely burns oil at high rpm...
I'm starting to look into this table in order to resolve some switching errors (CEL) that I'm getting. The 02's don't oscillate as high and low as they should when under light throttle. They jump...
I just had this happen to me last night! I filled up and all of sudden my logs were all screwy. I assumed it had something to do with the charcoal purge (evap) system so I didn't mess with the tune...
The cam has a 112+4 LSA. I'm sure there is some overlap there.
The problem is that the 02's aren't oscillating like they should. One thing to note is that the same cam has been in there for...
Hmm, I've been thru the grounds but good idea! I'll check that out and see what's up. C5's are famous for electrical gremlins...that could definitely be one of them!
FYI, the codes I'm getting are: P0133, P0153 (these slow response ones are normal for LT's), P1133, P1134, P1153, P1154. I have the rear 02's mounted in the FRONT positions (supposedly they have...
I have a modded 1997 LS1 with ported 243 heads, ls6 intake, 228/232 cam, Vararam, and most importantly a set of LG Street LT's with cat deletes, X pipe and z06 Ti's.
My problem is that I can't for...
I tried to use the DFCO setttings and I couldn't get it to activate DFCO for the life of me (the 02's would never go to zero when decelerating). I have it working mint on my 1997 LS1 so I do have an...
no one?
I have read every relevant post here in the forum regarding the LL8's and tuning. A friend has asked me to tune his LL8 before he heads out on a road trip to Michigan (from CT) so he gets better...
Are you measuring AFR with a wideband? If so, where is the wideband located? The AFR calculations based off a narrowband 02 are almost useless.
Are we able to enable lean cruise on our vehicles in the US? I know it's not "legal" due to emissions...but as far as reality...can it be done? Looking to get the 14mpg on my LQ4 up a bit and lean...
I'm interested! Now we just need some experts to step in and give us some direction!
I just bought an 03 6.0 4x4 2500HD also, looking to tweak the timing and fuel a little bit (inital logs showed a lean condition across the board of 5-7% in part throttle). I'm totally new to...
