Dual O2 plus EGT sensor
These Altronics O2 Alert warning and recording systems are the first data recording systems specifically designed to record air/fuel ratios with a warning output. Not only do they record up to 2 wideband oxygen sensors, they also record engine rpm and have a programmable warning output to protect against detonation. The systems feature a backlit display, a warning output, and software. The warning output can be used to activate a warning light, enable fuel enrichment, shut down nitrous, or retard timing. Recording can be started by a preset rpm value or switch, and can be played back on the system or downloaded and graphed to a PC.
Also has the added EGT sensor
I bought it last year and it was sent into Altronics and tested before
