Is ms w/wonky wideband dangerous?

The crap wideband lc1 I have keeps loosing its calibration and I am needing to recalibrate it often. I thought maybe I fixed it but still is giving me issues. I read that auto tune requires the wide band. Now I just started wondering, if at some point when i'm driving the car, if the wideband goes wonky, can it hurt my motor because ms tries to compensate?

If you're allowing an inaccurate wideband to autotune your car you could definitely blow it up.
If you've already got a solid tune and you're not actively autotuning the car, then your probably ok. Depending on how severe and frequent the loss of calibration you probably want to decrease the EGO correction limits or turn EGO off completely so it won't throw the tune off when you're in closed loop.

I don't know the terminology but all of a sudden the afrs jump around and maxs out at bottom and top and blinks 7.4. Then after I redue the free air calibration it seems to work perfectly. It looses calibration randomly when off and when running. I Guess I can try to run a separate line from the battery with a relay.
I was planning to install my msp today so I was planning to use autotune. The msp does come with a base tune so I can still hook it up and get the base timing set up. Shouod I hook up the wideband and just disable it like you said? It's a innovate btw

I cleaned it up a little bit and relocated the unit to under the radio area but yes, I still have the butt lines. But I'm getting good voltage.. My electrician friend who also has a wideband said it should be fine and that the 12v is solid and that adding a line from the battery is a unneeded complexity.

And to your question #2 & 3 no they aren't. You seem to want to do things 'temporary' then ask why **** doesn't work after. Then argue with everyone about it after the fact.

Your wideband will never work if you leave it wired like that. The LC-1 is highly sensitive to poor grounding, and you have it teed off the radio or something equally kludged. Did you read the directions that came with it?

A wideband controller is influenced significantly by minor differences in electricity. Butt connectors and vampire connectors can offer a greater resistance than soldering the connection. Choosing a circuit for powering the unit that will not fluctuate by having a load variation is important.
