With a LCD Display measuring nearly 1" the BigLog allows the user to see what is happening while driving down the road. The BigLog is also capable of recording up to 5.5 minutes of data to be viewed later.

Recording such things as:
A/F or Lambda
Battery Voltage
RPM
% load(TPS or MAP)
as well as an optional driveshaft speed input.

The BigLog A/F Meter can be configured either manually or with the included BIGLOG software to display either A/F Ratio or Lambda, adjust the number of cylinders for RPM calculations and compatiblity for either gasoline or alcohol.

An excellent tuning tool for any carb equipped car running either naturally aspirated, nitrous-assisted or a blow-through Supercharger setup. The Big Stuff 3 BigLog also features a programmable output to be used as a warning light to light up when a programmed lean A/F is seen to protect against engine damage before it happens. It can also output the AFR or Lambda values via a 0-5 volt linear ouput to an external data acquisition system or external dynomometer.
