Trying to get my wideband working and I noticed with nothing conected to the aux. inputs they display voltage? I thought they should be 0 with nothing hooked up. I just added a raw voltage pid in the...

Well I decided I had enough. I just ordered the plx dm-5 combo. Thanks for the link, I tried rewiring this past weekend just as they did in the link, and still same result. After doing alot of...

The wiring diagram you posted is exactly what bill said not to do. run any ground to the interface. Can anyone tell me if there is a way to check if what I am programming into the lc-1 is actually...

Okay Bill,

Here we go again: Everything worked great for one day. The next day, I put the laptop in the car and drove to work (it is a 35 mile trip). The entire trip, the wideband read between...

Bill,
You be the f***in man YEAH! pulled the ground off the mpvi works perfect!!!
I can't thank you enough, this has puzzled me for a week now.
:worship: :worship: :worship: :worship:
:yay:...

Bill,

Are you saying that I shouldn't run any ground whatsover off the MVPI Pro interface? Where did you read this, because everything that i have read says that it has to be grounded. Thanks,...

I have all grounds soldered together and grounded to the engine. I changed the following in the lc-1 config.: set output to afr instead of lambda. set 0 volts to 10 afr. and 5 volts to 18 afr....

I can't seem to open your attchment. I have the ground from the MVPI going to the engine, it is grounded with all the grounds from the LC1. I don't understand how this would be explain my problem,...

i have the MVPI Pro interface.
I recently purchased the LC1 and installed it according to the directions. Something is way off because it is showing me AFR arround 20-23. I have looked here, and...

Russ,
Thanks for laying it out like that. That is what a guy like me with no experience tuning needs. It may take me a little while to completely understand all of it, but a good place to start. ...

In every post I talked about the tune I said the tune was stock, is still stock and has never changed. I did not make any changes to decrease the ammount of kr. I also said the fuel filter is only 6...

I have not changed the tune at all yet. all runs were the stock tune. The car has 140k. miles on the clock. Cat, original. Plugs&filters 6 months old. I understand it needs more mods, and I know what...

Here is a new scan, I realize that I saved the file wrong in the last one. Sorry it took so long, I was having some issues figuring out the data logging. I only saw half as much knock on this run. ...

Where should I start? Scan attached! This is my first scan, I am new at this, so please take that into consideration, and I understand that I need to fix things one at a time. Thank You for any...
