I just purchased a UltraGauge for the ZHP. I was looking to add a Digital Coolant Temp gauge that would give a more accurate reading. When I found the UltraGauge I knew it exactly what I was looking for. This thing reads and clears engine codes, resets the "Check Engine" light, can monitor several parameters via the OBDII port. You can set alarms for the parameters being monitored which is really nice! If the engine coolant temp gets too high a beep sounds and the screen flashes. Very impressed with the quality and features with a unit that costs $70.
Change the screen color to match the BMW dash!
I will send you enough to do 2 screens for FREE!
Amazon has the colored film.
1. Cut a business card to fit the screen.
2. Use the first card and cut out another 1/8" wider all the way around.
3. Lay the larger card on the red film, tape it down to make cutting it easier.
4. Finished product!
5. Trim all four corners, aids in the install so they don't catch.

UltraGauge continually calculates real-time Miles Per Gallon as you drive. UltraGauge displays real-time and average MPG to help adjust driving habits for maximum savings.
With Real-time MPG, UltraGauge can quickly answer those age-old fuel efficiency questions specifically for your vehicle:
Is it better to drive with the windows down or use the air-conditioner?
Tailgate up or Down?
Do truck tailgate & bed accessories help MPG?
Is MPG significantly affected by tire inflation?
Which gear is best when climbing grades?
Which speed delivers optimal MPG?
Does engine braking use more fuel?
Does MPG change based on altitude?
Although dangerous, does drafting really help?
and many more....
With UltraGauge it’s instant and easy!
Unlike MPG gauges found in high-end vehicles, UltraGauge is not limited to displaying a maximum of 99 MPG, UltraGauge displays up to 999 MPG.
UltraGauge features fully configurable alarms for every gauge. Both low and high alarms may be set and the trigger value of each alarm is completely configurable.
UltraGauge continually compares real-time gauge values against configured alarm values. If the alarm thresholds have been exceeded, an audio and visual alarm will occur. The alarm window will display the set value and the current value. While the alarm is occurring, the particular alarm may be easily suspended and will no longer trigger for the remainder of the current driving cycle.
The alarm siren may also be disabled to provide only visual alarms. Alarms may also be globally disabled so that both visual and audible alarms are disabled.
An alarm may also be assigned to trouble codes or pending codes. Should a trouble code or pending code become posted while driving, an alarm immediately occurs. This can aid in the diagnosis of intermittent problems.
