-100% LTFTs?

Just installed an MS3 cam and I get -100% LTFTs all the time. STFTs look great, car has basically a stock tune as far as all the fueling and spark goes. It does run and does idle.

Nevermind, reloaded the config file and its all good.

Yup, if you are logging over 24 bytes on a pcm that only supports up to 24 bytes the software will drop pid's to get you back down to the max and it usually starts with the LTFT's.
