Looking at picking up an InnovateMotorsports LM2 Wideband Data Logger/Tool.

http://www.innovatemotorsports.com/x...cat=261&page=1

The question I have is if anyone has been running one on their car, and if you went with a dual O2 sensor version, or just a single O2. I will be using this to help with the tuning of my PES G2 setup (1998 A4 2.8), and also my TRD S/C LandCruiser.

With the LC there is no need for a second O2 reading, but with the 2.8 exhaust setup and the dual cats, my thought is that it may be necessary. I will be setting it up to also read EGT and IAT's, so will have plenty of data to digest.

Any experience / advice appreciated.

Cheers,

Steve
