LS3 Predator Tune - Code P2066 now...

I have a U7194 with the latest CROM in it for the LS3 08 vette.

Flashed it, drove it about 100 miles and now I get code P2066. I cleared the code and it came right back. I put the stock tune back in and it seems fine now.

P2066 says fuel level sensor.

What next?

yeah if you enter the tune parameters after a flash you'll get that code and the fuel gauge will not work, you can clear the code and the fuel gauge will work again however the fuel computer will not (0mpg when stopped / 70mpg when moving no matter what), i let mike know about it and hopefully they correct it...

meanwhile reflash or reset ecu to fix

So how do we edit parameters now then? I went into the params but didn't reflash - just poking around... If we edit a parameter and reflash is it okay?

yeah if you flash after "poking around" it's fine, hopefully they fix it

Just experienced the same fuel error and indeed the problem was corrected by installing a new tune. I will miss that 99.9MPG tho...
