But the UltraGuage is the best $70 you can spend.
You can monitor about 49 different things, my favs are the engine temp and inlet air temp.
The avg and instant MPG are not so bad either.
I might get the UltraGauge...the Sebring Convertible we have has a better computer than the one in the Crossfire...but I have not CEL, though...and I know it works.
