go back and check your wiring. check your sensor grounds. something isnt right with the wiring if thats happening

Re: what is going on?
stupid question but did you accidentally unhook a vaccum line?
also where did you get your 12V from for the wideband.

Re: what is going on?
the 12v is coming straight from the fire wall inside on the drivers kick panel. there are alot of tabs that you can connect to.
i shouldent have unhooked a vaccume line, i wasant by any.
my ground is also a bolt that holds the dash together. these both lit a test light up steady, so i figure it should run the wb fine

Needs to be grounded at the same place as the PCM.

open up your datalogger and start checking things like TPS voltage and such. MAP sensor ect. also you may have a corrupt BIN. try another BIN. umm. just try that stuff first.

Are you using the WB to simulated NB output to the EBL?, if so don't do it!, your much better off with a NB to pcm and using logworks to log the WB

Now that you have it back running on the NB and can log with logworks set up the WB to one of the ADC channel inputs that can be used for the WB or pressure tranducers and set it up in the EBL software.
Than you should be able to datalog using the EBL software and do VE learns with the NB or WB.
Sorry not much more I can help you with, don't use the EBL myself just have read about it.
Contact Dynamic EFI at bobr@dynamicefi.com for more info on setting it up.

it isnt neccesarily the min and max values that matter. you really shouldnt waste your time with log works. you really need to get the wbo2 to connect to the ecm, and you will have alot better tuning experience
