Anyone using an Innovate LM-2 A/F ratio datalogger

I've bought an Innovate MTX-L for tuning my daily-used '73 Dart. Later I bought another one to tune the seperate longram-intakes in my '60 Chrysler.
It's the most useful tool I've bought in a long time. It also has digital and analog-outputs for logging.

On a dragstrip you always deal with constant changing rpm-sweeps and always at fullthrottle. It will be good to actually 'see' if you're rich or lean at those situations.
If you're serious at dragracing, you might want to buy 2 of those MTX-L's, one for every exhaust to compare the left with the right engine bank.
If you're real serious you maybe want a per cylinder EGR-sensor to see if all cylinders do the same amount of work.

But since dragracing is usually more about having fun in Europe I would start off with one unit.
