I can't even come close to making this wideband work with tweecer.

I go to lmprogrammer and enter
2 volts afr 10
2 volts afr 20

I do that for both analogs. Go to caledit, do the payload write stuff. Go to calcon and have innovate afr selected. Start the car and it is going from 20-21 af. Not staying at one number.

This is only one problem out of many I have


coming close to selling the tweecer and getting a dyno tune.

Where are you hooking up the analog output, are u using a dataq, or EVP method, and you are going nowhere if you put


2 volts @ 10 afr
2 volts @ 20 afr

if you are using the EVP connection use this

0v @ 10 afr
5v @ 20 afr

please explaing where are you connecting the analog output

We've been working together to get his issue sorted out - he's getting wierd readings - even in LogWorks (LC-1 software). Seems like it is down to either a bad ground/wiring issue or a bad LC-1 unit.

If you want to drive down to Baton Rouge we can try swapping LC-1 parts and seeing if that makes any difference - we're also hitting the dragstrip on Sunday, great way to break in that new 4R70W.

somebody let me use their lm1 and it says the same as my lc1 software. the only thing is i used my lc1 sensor.ca

i am starting to think it is right

the car is acting like it did before i changed the plugs [125 miles ago]


^I figured out all those crazy numbers in lmprogrammer. It was set on custom, not gasoline.

thought I could get this working. Somebody gave me a FJ0 file that was supposed to work. It seemed about right the other day but not today. So I was going to do the way stanger007 told me. Enter 2v for high and low. Enter that and tweecer is showing 20.60-20.80 instead of just staying at a certain number. So I figure, I need to lower the volts. Enter .93 for low and 1.93 for high and it just stays at 4.64

Plus I was just baking out in the heat.
