I guess you could always git another cluster and see if that fixes it or not. <img src="/forums/images/graemlins/wink.gif" alt="" />

The difference between the SGII and the UG is that the UG costs less, gives you more information on the screen at a time, gives you 3 screens of information to scroll through, and has audible/visual alarms.

The only thing I don't like about my UG is that it's not seeing the voltage and you can't program it. Although...I haven't been able to git any custom programming fer the SGII to work on my T-100. <img src="/forums/images/graemlins/frown.gif" alt="" />

Fer example...I was able to put both O2 sensor readings on the UG and see that the front sensor was slow to respond after the engine was warmed up and then shut off. It used to take about 5-10 minutes after that fer the system to go back to closed loop. After I replaced the both sensors, it only takes less than a minute to go to closed loop. <img src="/forums/images/graemlins/smile.gif" alt="" />

These are the (33 plus the 2 UG ones) gauges Ultra-Gauge sez it recognized on my 1998 T-100 SR5 2WD auto...not sure what it will come up with on the other T-100 year groups.
