Exhaust bung?

[Fbomb]

Should the sensor stick out of it or should the sensor still be recessed in the bung when screwed all the way in? Doing an install on an LC1 right now and this doesn't seem right.

[DETROITMUSCLE]

the sensor should protrude out into the exhaust tubing, look at your O2 sensors thats how its supposed to look.

Yup - it will look identical to your normal narrow band O2 sensors.

Weird, wonder why innovate gave me a bung that's like 2" long. good thing i have another one. almost done, just have to weld it. drilling bungholes can be painful...drill caught and forced my hand against some sheetmetal joint. bleeding now.

The innovate bungs are shitty metal, and yeah - they look way longer than the ones I or Brett had.

Funny thing is that my second one was from Innovate too. Went out for a run last night, car's rich down low and lean up high. Oh yeah, probably forgot to mention that this one doesn't have narrowbands. I'm tuning a carb.

I need to buy a serial to usb adapter in order to datalog with my comp. Will any adapter work or does it have to come from innovate?

[MP81]

I'd imagine any one should work.

A carb will do that down low because of the squirter/s. And you want them to run a LITTLE lean up top. Although ive never tuned a carb on the street with a wide band, i dont think it would be much differant. It will be interesting to compare plug readings to the wide band readings. Let us know what your findings are. If it is the squirter causing the rich low end condition, it should clear up by 3 grand I would think. Good luck, Eric L

Figured out the step-up springs were causing the rich condition down low. Haven't checked plugs yet. Had springs that would lift metering rods at 3" Hg now have springs that lift at something like 5. Should probably swap to smaller jets in the primary and smaller metering rods now though. Went richer on the secondary jet and WOT afr is now in the high 12's. Going to the dyno on Wednesday.
