[EVI]

I don't know what happened my LC-1 worked perfectly in the fall, when I tryed to tune a car this spring it wouldn't read anything but 0. I've spent 3 days trying to figure it out. Read everything I could on the forums. I think all the settings are correct. CAN SOMEONE PLEASE HELP ME FAST!

EVI,

Welcome to the forum...:cheers:

Are you saying all AD1, AD2 (and if V2: AD3, AD4) all show zero volts...?

What happens when you place a 1.5V AA battery on any AD input, what voltage do you see from the scantool...?

Have you tried calibrating the AD inputs...?

Can you post a new log file (one where the AD voltage is zero).
Also, can you post your calc_pids.txt file.

Have you done the following:
- LC-1 heater calibration...?
- LC-1 free air calibration...?

What build version is your scantool/tunetool software...?
Do you have FlashScan V1 or V2...?

Thank you for answering. This is the first time I've used the forum. I talked to Ira today and I think we've got it figured out. We think the A/D input card or whatever the name of it is, is blown. I'm going to get a serial cable and just use that input location. If it doesn't work Ira said he could fix it for me. Thanks again for the quick response.

No worries, I glad it's being sorted out.
