I recently put COS5 in my car, so I thought I would have a great day of tuning w/the LC1. I got some done, but the wide band keeps going from a status of working to
one where the AFR = 1.2 on the meter. Yesterday, it did this and I ignored it thinking was was an intermittent error because I have never seen it happen before.
Today, I cranked the engine and it was working fine. Went for test drive, no problem. I get back killed engine, restarted. Its no longer working right. Has anyone seen a condition where it reads an extremely low AFR like this?

I use serial logging, but use one of the AD lines for an analog output. Thats the 3rd LC1 for the Vette. Have the same one in my FORD truck, but it doesn't get used much.

When this happens, it won't let me comm with it using LM Programmer either.

Ideas?

I had a bad sensor that would completely drop connection to the V2.

I just noticed 2.06.40 is available and updated about 5 mins ago.
